1984 Ford 2.3L powered Bronco II

Post #1 by MechRick » Sat Jan 31, 2015 4:32 pm

Here is the build thread for my current project, a 2.3L Bronco II. This came about from a desire to have a small 4x4 for commuting/off roading. My current 4x4, a 1994 F150 extended cab is just too big for this. Plus, it's setup for towing. The Samurai's I've had were too small, and underpowered.

I wanted a Cherokee. Unfortunately, anything with a Jeep logo was way overpriced for my purposes.

Why 2.3? Well, I've built 7 of them, two turbo cars and a Mazda B2300 among the 7. Here are some examples:

2.3 Turbo Pinto, blow-through carb, at a local car show.

Mustang.jpg

Megasquirted 2.5 Lima turbo Mustang Notch.

IMG_1076_w_zpsf93f1c6d.jpg

Mazda B2300 with a BW T5 transmission.

The general consensus on the -net is a 2300 BII will be underpowered. But a BII is only going to be 300 lbs heavier than a Ranger 2wd. And that Mazda I built ran great.

I briefly thought about building a 2.8L Cologne V6. I have Sven Pruett's book on the Cologne. Two things dissuaded me. Reports of 2.8L mpg numbers and those crack-prone cylinder heads.

Something else to consider. The carbed 2.8 was only rated at 115 HP. It won't take much to exceed that number with a Lima.

So without further comment, here it is....

And here is the powerplant mocked up with header and EFI (although I've decided on a Holley 2300 instead).

This build thread will be loaded with 2300 tech. Much more to come...

Nice work..It's obvious you should know how to make the 2300 operate. A few projects back, I ended up with an 84' BII 2.8 powered. I had collected parts for a turbo'ed 2300 version and was very close to dropping it all in when Became interested in the full size version which I now work on.

http://therangerstation.com/forums/album.php?s=41c24e89f606cf03e701453195cbf8e7&albumid=1555

I procured many late 70's/early 80's heads and intakes that are so popular with the local racers here in my area. I built two motors, and had 3 spares I think in my shop. I became disillusioned though in the poor quality castings in stock Ford ranger manual trans bells for the TK's. I did NOT want to use any other trans myself. I also had some m5r1's for use but found that unless i could get a stronger bell, maybe T5, I wouldn't proceed..

My thoughts were more about reliability and frankly I was concerned about any juice clutch failing in the WAY outback. I recall a Bronco I looked at that someone had sabotaged outside a bar one night. (it was an 86 with that goofy clevis pin for the slave line attachment). Someone had pulled the pin and she had fluid drain out so ..no clutch.

Anyway..soldier on, we'll give you an occasional pat on the back as we read.

http://therangerstation.com/forums/album.php?s=41c24e89f606cf03e701453195cbf8e7&albumid=1555&pictureid=9775

BTW when I sold this project, I could get 20mpg on the highway with it...with an Auto-lite C2-1.01 jetted .044. I also had converted it to manual steering, and manual brakes, and it was very drivable..so much so that my partner of 40+ years used it as a grocery getter....

I still have a few Esslinger tools around...

Funny you should mention bellhousings....

photo2.jpg



On the right is the Cologne TK bellhousing. Up to '84 they were external slave cylinder. '85-up were integral slave which necessitated trans removal for replacement. That will never do for the apocalypse BII. Any repair has to beat the zombie hoards. :rolflmao: On the left is a 2.3L Lima bellhousing attached to an A4LD. Notice they are completely different. The 2.3L bell pattern is a modification of the 2.0 EAO pattern. The top two holes are further up and closer together. The dowel pin diameter is also different. Older 2.3L engines had both patterns. One could swap a 2.3L engine into a 2.0L vehicle as long as stepped dowels were used. Interestingly, the 2.0 pattern is the same as CVH escorts, which is the same as the Zetec and the Ford crossflow engines (pushrod 1.6 as used in the old Fiesta). The Duratec 2.3L is a Mazda pattern and completely different.

The TK4 and TK5 transmission was installed in early Rangers, so I'm looking for the 2.3 Ranger bellhousing. I've located one out of state for $100, but have been hoping to find one local.

I've heard that the Mitsu FM146 bellhousing will work with the TK. Can anyone verify this?

Found a pic of a 2.0 EAO RUG 4-speed (left) beside a 2.3L T5.

The difference in the top two bolt holes is evident.

I'd mentioned previous builds. Here are a few...

GreenEngineR.jpg

Build 1..low compression ported head, ended up turbo.

engine2F.jpg

Build 2, same.

trhot.jpg

Build 4 (build 3 was for a mini stock racer. No pics).

longblocklf.jpg

Build 5. Low compression forged 2.5 for turbo use.

Build 6 was the Mazda, build 7 block is at the machine shop now going .030" over...

Build 4 was 9.5:1 with 1.89" intake valves and 1.59" exhausts and ran very well, propelling a Fox body nicely. I drove it that way for a year before turbocharging the 2.5 and dropping it in.

My goal for this 2.3 is as much compression I can run on 87 octane. I'm thinking 9:1. The limitation is the open chambered oval port head I'm going to run. I will run the 1.89" intakes but stock 1.54" exhausts.

One of the things I liked about the 2300, you could use a roller cam very easily. I scrounged around for the cams and followers

What head/intake combo are you using for the carbed build? (I see you said oval port)

About your fm146/tk question..I always wanted to try that (I had an FM146 in an 88BII) I just never had all the parts on the floor at the same time and the 88 was a DD for a while. I passed on FM145's.

I see your T5 bell, you might should put together a 4wd version T5?

After thinking about it..If I were going to do this again, I think I may use the c3/5 4wd route. I have a friend who runs a turbo'ed t-bucket here locally using an auto. The 2300 auto-bells are a little hard to find around here though as well. You may not quite get the economy, but it may be more drivable especialy 4 wheeling some.

1974 2.3 Pinto. I would love to find one of the elusive 'Z' manifolds that allow a Holley or Motorcraft 2bbl to bolt up. If not, I have a port plate adapter to match a 'D' port manifold to an oval port head.

I will do this also. Trying to find someone to regrind a stock roller for a bit more lift/duration. Crane rollers retail for more than $400.

Only viable one is the non world class Jeep T5.

Number one priority is MPG. My goal is 23 mpg. The Mazda was getting 26, so I'm hopeful. I don't think I could get there with an auto.

At one time I had two of those along with 3 late 70's oval port heads. I had one cut for the Oversize stainless from Esslinger and had it all prepped for one of the manfolds. Instead of finishing the motor I sold the blocks(2) and heads separately..

If I run into another manifold I'll now where to send it. All of these are pretty useful here locally but I'm not going to build anything but maybe another 300-6 short block (for a spare)..and THAT most likely won't happen unless I just run into another deal. Before I'd build another 300,, I want to find a Roller cam/follower setup to use. I don't like risking a flat cam...I bought one engine with that problem already once...

Have fun....

My 2.3 sore spot. Built 3 of them 2 for friends running mini stock. Biggest difference was 3 different ways to lube the cam other than the cams themselves. My version was for a DD Pinto at a cost of around 2500.00. drove it about 3000 or 4000 miles. A trip to fla from indy neted 28 to 32 MPG running 70 to 80 MPH. At that poit was dreaming of a 5 speed instead of a 4 speed. Raced a couple stock turbo 2.3 and would out run stockers. Once a vett pased me doing around 90 to 100 and passed him at 120 could smell the new clutch burning a bit and slowed down the vet never came after me.
Got interested in a 81 200 six mustang and pulled the 2.3 and stored it for around 25 years. PUT IT IN a 88 Ranger that had a 2000 2.3 version with a 5 speed. Gave it to my son and someone hit him and totaled the vehicle. The only thing I missed was the engine and 5 speed but his being 400+ miles away and his economic situation lost the vehicle. Realy bummed and doubt he will ever get another freebe like that from me again.

That little green Pinto had build 1 in it, with 8:1 forged pistons. I intended to turbo it eventually. But I remember once, when it had the header and a weber 32/36, chasing a built ElCamino up the seven percent grade on the way home. I couldn't pass him, but he couldn't pull away, and I pushed him all the way up the hill at 110+ mph. :twisted:

One regret I have is never dynoing any of my builds. The 2.5 turbo went to the strip, running mid 14's on very slippery street rubber. I think that one was making way more power than my guess of 230 RWHP.

They will fit the Pinto nicely. A Fox body driveshaft is a bit long, but works without bottoming the transmission output splines.

Notice the big dimple in the engine crossmember to clear the clutch cable.

on the roller cams when i was at Crane in the early 90 they came out with thier own roller cams for the 2.3s.
They used the OEM roller arm and lifter from the 88? or so 2.3s and
of course had a smaller base circle than stocker And there was the one that made it work and that was to use SBC length valves.

I'm a big fan of the Pinto 2.3 engines. I had a couple of 79 Stangs that had the 2.3 Turbo engine.

I've actually prepped a set of 1.94" Chevy intakes. Cut them down to 1.90", trimmed the stems a bit. They will not work on the stock base circle due to the extra .100" in length. If I can find a grinder that can regrind the stock roller, I can use the Chevy valves and save about $80 on valves, and about $200 on the cam.

One thing to worry about is using the shorter stock 1.54" exhausts, which I want to do, because of the odd tulip shape of the Chevy exhausts. On the exhaust side, the valve will be shorter, and the lifter sit taller. This will change the geometry somewhat. I think it will narrow the lobe centers a bit.

Camcraft advertises a regrind service, I'll give them a call...

Block is back from the machine shop. This one got extremely hot and had to be decked.

SAM_1975.jpg



Notice the goldish tint of the bare block. I've been told this is because of the high nickel content of the iron used in 2.3 blocks.

On my last build, I used KB hypereutectic pistons, for the main reason of reducing reciprocating weight. The KB's are light, but expensive ($200). One of them came in a few grams heavier than the rest, and I had to whittle some weight off of it. This time I'm using speed pro pistons. They are very reasonable, but heavy. Dropping one on the gram scale with the pin shows 666 grams. Well, at least it's keeping in step with the apocalyptic theme.... :hmmm: All of them weigh the same, fortunately.

SAM_1973.jpg


I dug the crank out of the shed, where it's been for a few years, and the machine shop gave it a good polish. Clearances are right where you want to be with a street performance 2.3 at .0015".



Checking the machine shop...

SAM_1989.jpg


All four were right on the money. My typical street 2.3's use stock rods. Reportedly they are good for 400 HP. I like the oil squirt hole that limits piston scuffing. I will remove the balance pad from the small end to reduce reciprocating weight, always a good thing on a four cylinder. I will install ARP rod bolts and polish the beams a bit, and weight match.

SAM_1985.jpg



I think on this build I will fabricate a crank scraper and windage tray. This alone is supposed to be worth 10 HP on the 2.3L. In the past, I've used the Esslinger tray with good success.

Have you ever tried "floating pins"? My t-bucket friend always runs floating wrist pins in his 2300's. with a drilled oiling hole in the small end of the rod. I prepped a set of rods for my last block..but never used them

How will that little 4 banger go pushing the Bronco along ? Given the Broncos had either a 6 or V8. Great project I have to say.
V8's are great but Six Inlines Just Fine. Cummins Advert.

The baby Broncos always had a V6. Either a 2.8 or 2.9. There are rumors of 2.3L and 4.0L Bronco II's, but I've never seen one. The 2.3L four is a torquey engine. They pull Rangers around just fine. It won't be a powerhouse, but it will do ok.

Not much meat on the small end. I thought about running steel on steel once, but don't want to send them out. I would run Esslingers or Crowers if I wanted floating pins.

Also, the Speed Pros don't have circlip grooves.

Nice. I remember during the overlap between the Pinto and early Fox body (1979-1980), most SCCA racers stuck with the Pinto chassis. It was well sorted combination by then, leaf springs and all. That gutted Pinto probably weighs less than 2200 lbs.

Man I wanted to do one of these so bad in my 56' let the guys on the hamb convince me otherwise. I have since pretty much moved away from that place. They won't accept reality...... if it isn't a V8 they don't want it.

I have a chance to get my hands on some local 2.3L. I need to grab them before they go to the molting pot. What year ranges are the best? They mostly have the 8 spark plug versions from rangers. They worth swiping if the price is right?

I would like to here more about turboing one of these. I had always planned to get one from a turbo coupe. They are getting harder and harder to find. What did you use, turbo size, brand, rods, carb type and setup.........

My first truck (97 ranger) had a 2.3L I always wanted to build it up, and couldn't afford it. So I have always had a soft spot for them.....

The best ones to build are the blocks that were the start of the one piece rear main seal (1985) up to the end of the single plug engines (~1990). The dual plug engines were rated at ~105 HP, but they also were a bit higher compression. If you mill the single plug (open chamber) head to match the dual plug compression ratio, HP is equal. The large main journal blocks/cranks are a bit stronger than the small journal stuff, but my 2549cc turbo engine used a small journal block with the 2.5L Ranger crank, and reworked stock rods. At one atmosphere it was plenty strong, and made plenty of power.

There are stock crank/block turbos out there at 50+ psi making upwards of 900 HP (with Esslinger heads) and they live.

edit: By the way, the 2.3L is most prevalent in Mini Stock racing. These 'stock' engines in some cases with no more induction than a 2bbl Autolite or Holley are making upwards of 190 HP.

The turbos I've used are stock Garrett T3's as used on Merkurs. They came with 60 trim exhaust turbines and were well suited to the 2.3L. Mine started building boost at 1200 RPM and had full boost at 1600.

T3-T4 hybrids are also a good choice. Some are using the throwaway Cummins turbos, such as the Holset HX35 series. One of those on a well-tuned, stock cammed 2.3L at 19-20 psi nets 400 HP.

Quick update: Rods have been weight matched, balance pads removed, beams polished. Weight started at 638 grams, now 617 grams.

pistons1_zpscrlnabnt.jpg


Four cylinders can be helped in smoothness if the reciprocating weight is lowered. You don't want to reduce rotating weight, though. Improving the rod/stroke ratio helps with the secondary balance issues also. The next 2.3L I build will have 5.7" rods in it and pistons that weigh about 400 grams. More on that later...

pistons2_zpstmefe6a1.jpg

pistons3_zps60qweldb.jpg



The rods are press fit pins. I heated them with a propane torch until the rod small end glowed 'brown', and slid the pins in.

I'm going to experiment with the oiling system on this engine a bit. Windage is a problem on the 2.3. The Esslinger trays are supposedly worth 10 HP. I'd love to see that before and after dyno run.

The 2.3L has a lot of oil flow to the head. The oil pumps, according to Rick Byrnes (noted landspeed racer) flow as much volume as a 460 V8. Looking down the oil returns through the cylinder head and block, the oil returning from the head dumps right onto the crankshaft. The return passages are straight drillings slightly over 1/2 an inch. I might drop some tubing through from the top of the block to direct the oil flow toward the sides of the block or even through the windage tray. Any thoughts?

I'll throw up some pictures soon to illustrate what I'm thinking.

1 If you are running a roller cam you might be able to restrict oil flow(a little, not a lot) to the head.
don't even try it with a standard slipper follower cam.

The bigger of these two brackets might bolt to your block, I'm not certain how many or which dimensions 2.3 and 3.3's share, just eyeballing your block they might be close.

The factory roller cam engines have an oil restrictor that screws in place of the oil gallery plug in the left rear of the block, where the oil passage is drilled up through the head gasket. I would like to restrict oil to the roller cam, but two things give me pause.

1) I'm using a high volume oil pump from a turbo engine (just because I have it).

2) This engine will spend some of it's time at less than 1000 rpm crawling over rocks.

Number 1 is the real worry, because if the 2.3 has a weak spot, it's the puny distributor gear. They can strip teeth if oil volume exceeds the restrictions in the engine (bearings, etc). High volume pumps are overkill for this engine. Maybe I should get off my wallet and buy the correct oil pump for the application.

I'm pretty familiar with the paper concept.. Last night I used a stock 250 lift bracket to pull the measurements off, then modified the lift eye hole (round instead of oval) and practiced redrawing it a couple times before I asked for it to be converted into a DXF.

Last oiling modification was to braze some copper tubing together to fit the oil returns in the block. The idea is to shunt the returning oil off to the side instead of it dropping on the crank.

Notice the gold tint of the block is gone. It's now painted Duplicolor cast-iron gray...

In theory, this should help. It's unproven though. I got the idea from how the oil returns through the windage tray on SHO/Yamaha V6's.

Hello MechRick, enjoying the build so far. Learning a lot! I'm interested in doing a 2.3 now. Could you give some more information on the oil feed tubes? Are they brass or copper , like plumbing tubing you get from a hardware store? whats the actual diameters & lengths of the pipe & connector sleeves? I think that's a great idea. I'd like to see your windage tray design when you get there.
Out of curiosity, since you are very knowledgeable about these engines, what do you think of the Volvo 2.3 DOHC head conversion? Is it worth it? Does it work well & how much is actually involved in doing it if you know? thanks!

It's garden variety 1/2" copper. The tubing itself is a bit too small to fit the drainback holes, but the couplers are perfect.

I figured solder would not work in an engine with the vibration and heat ( the last thing I want is a section of copper tubing impacting a crank throw at 5000 rpm). I used HVAC grade brazing rod at 1200 degrees to join the sections. The lengths were chosen to stabilize the tubing in the bore and sit flush with the top of the block. The front sections bottom on the front to back oil supply gallery and the rear section bottoms on the right side of the block.

Note that this might be a total waste of time, because I have no idea if it will liberate any HP. Esslinger states that their windage tray frees up 10 HP, but I assume that's on something making a whole lot more HP than what I'm building. If I free up 4 HP I'll be happy for the time I've spent. I'm a firm believer in *free* HP. I like to see what can be done without impacting fuel economy. So, porting, breathing, compression, oiling system and maybe a slight camshaft tweak is what this engine is getting.

I think a tray would be redundant at this point. I may leave it as-is. What do you guys think?

The Volvo head swap has been done numerous times.

With the external oiling and the welding and the custom intake needed, I felt reliability would be compromised. I'll stick with Ford parts on this budget build.

Hello MechRick, I agree with the HVAC brazing rod. So, the tubes bottom out on the engine casting. Does that mean that all the return oil exits the tubes through the two cross-drilled holes you made in the tubes? If so, wich direction do the holes point in the engine?
I think the windage tray is still a good idea. I would do it, just for two ideas. 1) It may just be a matter of just bending some sheet metal and maybe bolting it down to the oil pan bolts? & 2) It may help with oil slosh in the pan if you get into any exaggerated angles when rock crawling?
Will you be doing your own porting? And, will you be sharing any pictures of the procedure? I'm really interested in that as well.
Thanks! and have a good day.

I think most of the oil will flow out the bottoms. They rest on curved surfaces, so I drilled the holes for extra flow.

I'm thinking of a baffle in the oil pan. I can shape one and spot weld it in much quicker than building a custom tray.

I've already started. I'm working on the intake bowls at the moment, oversizing them for 1.9" intake valves. I will take pictures as I go. The 2.3's respond well to porting, and show improvements everywhere, even on the bottom end.

Moving right along on the Bronco, and I've come to the first major compromise.

The input shaft on the Toyo trans had some scoring where the pilot bearing spun. While researching bellhousing options, I noticed that the '85-up bells with integral slave cylinder mounting were much more common (and thus cheaper) than the '83-'84 external slave version. The transmission input shaft length changed between the two options also, the later version about an inch shorter. So by going to the later bellhousing, I could fix the issue with the galled input shaft, as it will need to be shortened about an inch. I bought an integral slave to make sure it would work with the older style Toyo 4 speed, then ordered a late bellhousing from a Utah wrecking yard ($60 shipped).

So, first picture is of the input shaft, which will have to be shortened...

input1.jpg



And the slave cylinder. Bad part of this is the trans has to come out to replace these, but the good is the quill and throwout bearing are part of it, and get replaced too...

slave_cyl.jpg



Speaking of the quill, the Toyo quill has to come off for this style of slave to fit. So off comes the front cover for a little cutting....

quill4.jpg

quill2.jpg

quill3.jpg


Had to file the ears of the slave slightly, as it gets pinched between the transmission and the bellhousing, but it fits. Bolted it together, just have to shorten the input shaft once I get the correct measurement.

trans1.jpg


This shows the excess length of the input...

Last update is I've abandoned the baffle idea, because I stumbled across a windage tray from a Toyota V6 application that I can modify for the 2.3L.

Needs some trimming, but the bore spacing is close enough.

From the oil filter location that is probably a 2.0L German Ford...neat intake.

I've got the tray modified to fit. Took a little cutting, grinding and welding. It's anchored in 4 places with .100" clearance to the rod bolts.

So, the Speed Pro pistons require me to make another compromise. The assembled short block has the pistons down in the hole about .023". This is not uncommon for stock pistons, but reduces quench, not a good thing for HP. I was going to run an oval port head with the big combustion chamber on this engine. I've already started hogging out the intake bowls for bigger valves (before the idea of the Bronco II took root). Problem is the compression will be low without a fancy (read expensive) MLS gasket or excessive milling (also costly).

I've built a few 2.3L engines with the D port head, and like the way they run. The D port comes in unshrouded (turbo) and shrouded (fast burn) designs. The shrouded chamber is similar to the EFI 4.9L chamber, and works well for economy/torque. It's also smaller, which will bump compression. The swirl characteristics of the chamber negate the need for quench, so no fancy gasket needed. So, off to the junk yard I went, looking for head and roller cam/followers.

I hit the jackpot.

Now I have a roller-equipped D port head that I can clean up, port, do a valve job on and bolt to my short block.

I realized I didn't need big valves to make 130 HP (or even 115 HP). 1.74" intakes will get the job done, even with the heavy intake valve shrouding.

P4250016.jpg


The intake I stumbled on is a D9 prefix, known to mini-stockers as the Z intake, because of the channels in the plenum floor.

P4250018.jpg


It is an oval port intake, developed for production in 1979. The earlier intake was a D4 (1974, from start of 2.3L production), which is slightly more desirable for racing due to more plenum volume. There will be some port mismatch using an oval port intake with a D port head. Notice the oval port gasket on the D intake ports...

P4250015.jpg


I'll keep searching for the correct intake, prefix E1 (1981). That is a carb intake that matches the D port head. Ford was changing the intake and head design to reduce fuel puddling in the plenum and runners when cold. Early 2.3L's were cold-natured. There isn't really a power difference between the two head designs.

The nice thing about all of the intakes mentioned above, is that once you remove the Weber 32/36 or one-barrel adapter (not shown), a two-barrel Holley or Autolite/Motorcraft carb bolts right up.

P4290019.jpg


The Holley pictured will have to be reworked for four-cylinder use, namely PVCR restriction and accelerator pump pullover, but should work well...

I picked up another old Ford inliner over the weekend to play with...

Anything new on the 2.3? I'm really enjoying the build. But I have to admit I don't understand all the T-5 stuff. If I wanted to do something like this, would the dual-plug head be okay? or should I really hold out for a single-plug head?
And as far as I'm concerned you can talk about the tractor too! thanks.

I've got the engine together and am starting to work on the engine mounts. Have a bunch of pics, once I get the engine location finalized this weekend I'll upload some more...

The tractor has been a joy to work on. So simple compared to modern cars. So far I've rewired it, changed oil, added some missing parts (sediment bowl and fuel line). It runs, but this weekend I will install a starter bendix and diagnose the hydraulics.

The last steps in assembling the engine was to cc the chambers to determine what the static compression ratio will be.

SAM_0104.jpg

SAM_0107.jpg

SAM_0102.jpg


Starting with 100 cc in the burette, the chamber consumed 56 cc. With the pistons down in the hole ~.023", the ratio will be 9.00:1.

The junkyard yielded mounts from a '94 Ranger. I figured since the Bronco and the '94 Ranger were both twin traction beam, the crossmembers would be the same. They were close, but I ended up over sizing the hole in the mount brackets, slid the engine around until it was happy, and tack-welding washers to the brackets. Removed everything, and final welded the washers.

I'll paint the Bronco gray with a red stripe, so the engine ended up in similar colors. I had a long tube header left over from my Pinto project. I was hoping it would fit the Ranger, but #3 tube wanted to occupy the same space as the evaporator plenum. I went back to the wrecking yard and picked up a Ranger shorty to run for now.

The Holley 7448 2 bbl is a V8 carb. It must be modified to work on the 4 cylinder. There are two problems. Vibration, and vacuum signal. Vibration can cause the accelerator pump circuit one way check valve to resonate and pump fuel, even when the throttle isn't moving. The fix is to spring load the ball or pintle under the squirters, or chose a carb that uses the steel check ball instead of the rubber flapper valve in the float bowl. Vacuum signal problems happen with big venturis at wide open throttle and low rpm. The 4 cylinder only has power pulses (and intake pulses) every 180 degrees of crankshaft rotation. At low engine speeds, the air flowing past the venturis can reverse and flow backwards through the carb. With multiple passes through the venturis, the air will pick up fuel each time, causing a rich condition.
