BA DOHC too good to be true

Nizpro sells the new ford 4.0L DOHC turbo 6 long motor, minus manifolds, for $5000 as a crate motor! This is too good to be true. I was going to have to build manifolds for my turbo 250 anyway and the bottom end was gonna cost atleast $4000 once I included all the parts and machining. Another $1000 for an engine that can handle 700hp on standard internals is well worth the effort. Spread the word
 
I'm happy with that.

5 large for a short block is fine until you consider it will


a) need an ECM

b) a specific transmission which won't fit the X series unless you do a rack and pinion conversion.


c) Becasue of the BA running a single row chain, I'd say it won't allow the early OHC head to be bolted on, so if you mess up your EA-AU 3 or XH ute ohc engine, it can't be used as a cheap upgrade. You may only have to do some minor mods to fit it to an E-series, but its all the other things that go with it.

d) Consider also that align boring the pistons or crank tunnel won't be needed to be done by Nizpro unless the engine has been slammed. Major clean-ups of the existing block is therefore going to be nil, so you are paying a lot for a premium crank and rod/piston set from experts in the business.

I like the window sticker you could run.


1500 HP TURBO TESTED NIZPRO BLOCK. :P :P :P
 
Maybe you didnt understand. Its a crate "long" motor from ford through nizpro as ford dont sell thier engines direct to the public, different to a short motor that comes without the head, its more like like taking a new BA falcon turbo sedan off the show room floor, removing the manifolds and trans and engine mounts and lifting it out. DOHC 24 valve 4.0L I6 that has been proven to hold up to 700HP at the crank for over 35,000km so far on stock internals! I am doing a rack and pinion conversion along with a coil over macpherson strut conversion and scalloping the shock towers so thiers more room for the turbo. I'll probably get a hollinger 6 speed and get CRS so biuld a bellhousing to suit. And I was going to have to get an ECM for the crossflow turbo anyway. This is a track/road race car project and I dont care if it takes 2 years to get the funds for all this. I'm buying the long motor as soon as the ute is finnished at the pannel shop, cant wait.
 
Funny, Ford NZ are willing to sell turbo long blocks to the public @ $4500 NZD! I priced it up the other day and was happly suprised, but was left wondering if an aftermarket computer will run the VVT on the Dohc head? I assume motec would but Damn - the price. Was thinking of using the turbo long, with my T04E + custom manifold and my orignial EF inlet manifold (well at least the bottom half), as I think it's going to cost me about the same to building up a nasty OHC engine. Still humming and harring about it.
 
I asked Nizpro the same question. Yes aftermarket ECM's will run VVT but yes expensive. On the otherhand ford sell the standard BA turbo ECM as a replacement part for AU$400 and then Nizpro sells a piggyback "Flash" system for $2000 including tuning. Reasonable compared with the 7000 for a MoTec!
 
So, what does that tally up to?

•Motor
•Physical installation
•Manifolds
•Turbo
•ECM
•Aftermarket mods
•Harness

Not cheap! But at least its available, even if in a back-door sort of manner.

I do wonder if any will end up in Skylines... And would we speak to the owners? :lol:
 
I can imagine the many, many hours on a dyno tuning the MoTec for just the iVVT alone.. I'd hazard a guess that the cam timing maps are quite tricky to get right, let alone getting the fuel and spark to mesh in with the cam timing. Unless someone supplies a good basic program to get it rolling..

with the EEC-VI, dont you need to have Smartlock, the BA HVAC command centre, and a few other BA specific bits and pieces?
 
Disco. Kalgoorlie eh!
The ba has 4 separate processors for the hvac and smartlock etc, there is a bus between tehm but the engine is separate.
The aftermarket ecu is supposed to be able to run the VVT but as youve said it would be two more variable to play with, however you could si,ple switch from advanced to retarded in one step which would simplify things.
PS i think the BA intake and exhausts are the same as AU and el.
The BA cam timing (as abserved on the ford factory service computor) does not vary the cams individually only as a pair, at least thats what I saw, which was admitatly no load.
The whole deal sound very cheap.

Yeah it all adds up, but I was going to have to build inlet and exhaust manifolds anyways, i had to buy a turbo anyway, I had to buy an ECM anyway, I can do tuning on the dyno at work which saves paying sumone to do it. So basicaly the only extra cost is the extra $1000 for the engine over re-building the crossflow. I'm a mechanic and so is my father. My brother is an autoelectrician aswell so the fitting isn't too much of a problem. The only hard bit is getting the loom/harness. My bro can build one but the plugs for the whole shebang are hard to source so a genuine harness is preferable. Maybe a wreck but then I might aswell get the engine and manifolds from a wreck too, allong with trans! Do you think the Turbo loom would be the same as the N/A loom, cause I could flog the N/A engine off as a fitted and tuned unit with EL manifolds that I have here, and the N/A's are cheaper wrecks

Just some thing to think about I spose. I might just go the crossflow for the ease of the whole thing LOL
 
hey
whould it be hard to toss those cams in the bin and get some adjustable pully's one made up up with the adjustment there.
and then a normal computer should be able to run the engine easly.

Yes I have had the same idea but havent checked it out yet. Performance would be down slightly, but you could advance the cams seperately to give the best performance in your chosen rpm. I even thought of a tripple webbered twin cam head on an SOHC block with the early electronic dizzy. But too much stuffing around. Probly just best to buy a wrecked BA turbo and go from there. Buy the crate engine when that one explodes after giving it curry for 100,000kms.
