Conversion help

[gassed250]

Hey i have an ED 4.0 and an LPG system sitting in my shed doin nothin
and started thinking bout putting it in the transit, it will bolt to the standard mounts and i can get a bell to adapt it to my toploader from CRS (P/N bh91a)

Getting it in the van is no problem for me but getting it to go might be
I dont want to use the EFI and was planning to run LPG only but i dont know if i need the EFI comp for the ignition?

I also want fit an sc14 toyota supercharger and run about 9psi, This part wont be a drama either its mainly the ignition and getting it to run without an ECU thats got me

Any help please

thE sc14 BLOWER Wont make 9 psi on a 4.0 mate....Not a chance...
Use an XF dizzy mate... there is a slight gear drive mod u have to do to get it to work but its easy enuf to do

Cheers dynoed

Yeah 9psi is a little optomistic but 6psi is do'able considering an sc14 with the stock pulley will make 3psi on a 4.0 so if i overdrive it, it should make 6psi to about 4200rpm

It will be mad in a transit van.. One of my first jobs as a mechanic, was to do a cam change in car in a transit van... DAmm that was a pain in the arse, the push rods only just came out past the tunnel.. it hand an XF 250 in it with a XD alloy head manifold( single barrle)

A 4.0 in it would be Sweet as , as i hate doing lifers and cams in them

 

[gassed250]

Yeah it should go alright but the main reason for it is to tow my cortina around
It goes well with the 250 but the 4.0 has that little bit more poke and i relise that its going to loose some kw running straight lpg and an older dizzy
this is why i want the supercharger, to give it a bit more down low
it might not work but hey the sc14's are only $250



Checked out the two distributors yesterday, it looks like i need to turn the gear upside down and drill a new hole. Is this all thats needed to fit it??

As you can see the old 250's still got plenty of heart

Nice spoiler.

My thoughts exactly...

 

[gassed250]

Hey c'mon dont knock the spoiler
its to help with high speed (80km) stability :roll:

Its got a milo tin exhaust too

Old transits are cool! They are the only car I can think of that you can drive around in with the door open! Good for fresh air in summer. I drove one once with a 250 crossflow in it - it still had the low diff, so it had heaps of punch off the lights. What a pity it ran out of puff at about 120! It must have had a 4:1 diff or something in it.

Yeah there not a bad old rig, though i dont have the mod with the sliding doors, its got a 250 x flow and a 4 speed the diff is a 3.00

Its got a few mods like K-mac suspension, changed PCD from 5x160 to 5x114.3
its got the vented transit truck discs and 4 piston callipers and the huge GT falcon finned drums

^^^^^^^^That's still a ford, only it has a Bed in front of it.


The Ogura SC14 is fine for a stock engine with about 170 hp to start with. When reving at top revs with no intercooler, it has a capability of about 220 hp, tops. A stock EA to AU propane engijne is hard pressed to exceed 200 hp, so the SC14 sounds like a very good idea. If its intercooled, 280 hp is possible.

The Ogura is an 85 cubic inche supercharger, where as the Eatons in Commodores are about 112 cubes per rev. Since its 32% smaller than the stock supercharged 227 hp Commodore 3.8, then it needs to rev harder to make up for it. The little Ogura spins like a top, and can yield over 6 psi with the right drive.

It is better off as a fan clutched item, switched via the AC circuit like the CRS 3.8 V6 supercharger which Rod Hattfield did. I can attest to the 30% plus power boost.

One other forum member did a supercharged Cortina 4.1, but it was lacking in that it used a very, very sensitive Gas Research carb and Century converter. It was nicely arranged, but the carb then went into a stock 12" long EFI x-flow intake, and it was not a sucess. The Ogura is a two blade supercharger, and it does have rather savage intake pulses which cause major problems with modern propane carbs and long branch EFI intakes. Revert to known combinations which work properly and have a known track record.

In your case, its important to start with a basic CFI EA carb intake, and add the 216 HP (normally aspirated) CA 300 or 207 HP CA 225 carb, E-series converter (325 hp limit) and add a hat which then runs to an SC14 mounted where the power steering pump is on the OHC. Keep it simple. You may still be able to use the p/s pump and a/c pump.

Go for it.

Cheers for the input X

I will be using an intercooler as gas engines tend to run hotter
as for the gas delivery i was going to use the ED manifold but swap the TB for an modified XF unit. I have an Airod variable mixer that fits snugly into the mouth of the XF TB and is held into place with grub screws

The SC14 will be mounted inplace of the PAS pump

Im still in the parts/info hunting stages so it wont be up and going for some time but i will keep you posted

That Ogura mob in Japan are a busy bunch - they make tiny little electromagnetic clutches for photocopiers and printers too!
