Vt-Vy with Vn T5 possible?

[V6Q]

hi all, just joined, and got a few questions, ive got a 73 Hq kingswood ute, which, as a father/son project(me being son) is having complete bare metal respray, body, chassie, inside and out, ive rebuilt/resprayed my chassie awaiting the body back from the pannel/paint shop, atm it has a converted vn diff, 4 wheel disks, bw t5 and s1 vn, but my motors stuffed, and im trying to work out what motor i should use, ive got 2 s1 manual v6's and a ford t5(for the extension housing)

i was talking to a bloke yesterday and he had a vr commy with a vy v6/auto, to get around all the security rubbish hes kept the vr throttle body and factory vr computer etc theres probally more i cant remember, the security is the biggest problem with my HQ-v6 conversion, now to my question,
can a bolt one of my T5s up to a vt, vy etc, and then run the vn computer, what parts am i going to need, i allready need a new tailshaft no matter what, oh and will my extractors match aswell, there vn ones from castlemain rod shop v6 into hq,

i just need to know exactly what i need for the conversion if it'll work, ie which flywheel, what computer, atm its ready to take a v6 and t5, minus a wiring loom which is in the works
cheers guys
ill post a link to my build on aussiev8 if anybody's interested

Come on no one knows or has looked into it

T5 bolted up to Ecotec will be no problems, just will need a VS S1 V6 flywheel.

As for security, easiest way is to retain the VN computer and harness (will need some wires extended etc), and get an Ecotec tune burnt to the memcal.

Extractors will not work, different exhaust port spacing.

[V6Q]

cheers for the reply, thats good, all they way the vy? vs s1 manual flywheel or dosent matter, what sort of place could burn the ecotec memcal on, and the extractors are they completely different, the same bloke with the vy in vr thought it was only the last set of bolts or something was different, how big of a job to make them work be, its not prob got a welder, both extractors or just one

See my replies in these threads

T5 gear box in a vx

Vn 5 speed into 1997 VT?

[V6Q]

cheers mate, do you know by how much my extractors wont fit, vn-ecotec

[V6Q]

well ive read them both and got a question whats a bottom bellhousing bracket???,
i need a vs manual flywheel and starter,
clutch is cable allready,
tailshaft needs to be redone anyway
the computer is the biggest problem buick or ecotec becasue its going into a hq, can i keep the vn throttle body and vn computer to get rid of the security stuff?

Sorry I didn't read the thread, thought you were putting a t5 into a vt -vy commodore.

the ecotec can run on your current delco 808 (vn/vp) map program, but would require a custom tune and likely extending some of the wiring. the cheaper route would be to use an ecotec pcm and get someone with a memcal programmer to remove the VATS from the tune so it doesn't require a code from the keyhead/BCM

[SweetWagon]

Its where to bottom of the bell housing bolts up to the block, the buick bracket cant be swapped over, i have found the standard vt-vx auto brackets can be used, just need to drill out the holes a bit more on the gearbox and the brackets as they wont bolt directly together.

no worries so it can be done which is a good thing

cheers so idealy i should be looking for a vt-vx motor and auto, with computer,as well as a vs manual flywheel and vs starter, modify the lower bellhousing, bolt her all up and sort the computer out, and shes good to go
sydney would be the place to get the computer done?, im in near dubbo in central west nsw, the extractors will be a pain, has anyone modified vn extractors to fit ecotec,
so putting the vn throttle body and stuff on is no good, the bloke i mentioned earlier had a vy motor with vr throttle body on and factory vr computer, it was auto tho

Yeah ideally vs-vt motor with loom and PCM, as vy had a different sump and vx/vy had flashed based PCM so it would be more difficult to remove the VATS.

VN extractors will never fit an ecotec due to the different port spacing on the head.

Im not sure why he swapped the throttle body's they have the same sensors + you would need a custom tune ($$$$) if you retain the standard computer.

contact this guy for any tuning needs Dicks Electronics RTLS1: Services

ok another problem, are vn sumps the same as vs-vt, mines a modified sump because the hq rails, the pan needs to be at the back instead of the front, its a crossbred thing, vn top, hq lower

not sure about that, you will have to do some research on that one.

maybe contact ASR (they are in the sponsors section) and see if they can make you up a custom sump... wouldnt think it would be too expensive although i geuss it depends a few things

will do hopefully there compatable

Dont belive everything on here the ecotec will run off the standard vn vp computer ya dont need to change the tune at all or the throttle body for that matter we have been doin it in speedway for a few years now yes ya need to change a few plugs and extend a few wires but if ya get a auto elec to do it he will have no trouble at all.

[V6Q]

cheers thats good to know, i need a new loom made to get rid of all the stuff i dont need anyway, so thats probally the easiest and cheapest way to try first

I know it will run on the stock vn MAP tune as its been done on here before, but surely since the ecotec has different manifold, heads, cam and probably compression ratio it would need to be tweaked to run optimal?

The class my mates run in the computer has to be standard no tweeks at all and they are getting up to 200rwhp out of them on pump fuel the only thing they are allowed to do is put the resister in the temp sensor to stop it leaning out as they only run in 2nd or 3rd.

sorted now bought a 40,000k old recoed vp v6 and t5, both done and a wiring loom to suit my hq thanks all for you help anyways

[Vlt_Calais]

good combo mate.

[FstStig]

Holy Fu*k, Just get another Buick motor and be done with it. Much less headache, much less to swap over and in the end will cost A lot less.
