Vn Turbo
I have recently installed a supercharger on my vn v6. My friend has come to me with a T28 turbo from an R33 Nissan Skyline and has asked me for help installing it. To be honest i am in new territory when it comes to turbos. Is there any info you guys can add to help my dilemma. Is this a common conversion for VN's? The information he has given me about the turbo and his car specs are as follows.
Vn commodore series 1 v6
3'' inch stainless steel exhaust - pacemaker extractors
The turbo is able to pump 14 pound boost at its max.
He wants to push around 10 pound.
Aim 220-240 rwkw
it's achievable, kiss the pacemakers goodbye though or at least one of them, depending if you're going to use a cross pipe or not. there is a bit involved, so instead of us racking our brains, ask us questions about what you dont understand
i t28.. that may be too small.. something a little bigger would be better for starter..unless you are going to make a manifold/s it will cost a fair bit to do this convertion. it he wants to use a t28 he would be better off using two.. one way it could be done. it turn the headers upside down and back to front. you may have to use standard manifolds if they won't fit. have the manfifolds so they are pointing up and to the front of the car.. even then they still might not fit. i haven't ever tried doing it.. ya would have to mount the coil pack in a different spot.. it is endless what ya have to do. all depends on how much time ya go i spose

I understand what you mean as room is needed to get to the exhaust but do i actually have to get rid of one side his extractors or just turn one of them upside down. How much roughly would this cost if my mate just got installed by turbo specialsist? T28's are not too small for vn commies. This conversion was done by a street machine vn 6er at 12pound. Ran perfect. I have a prestige adelaide mechanic lined up to make mainifolds.
well there ya go then., i thought it would have been too small. it would cost a shitload to get a turbo place to do it i reckon...
oh and even havter it's been cooled whast the chances of the motor handling ten pounds stock??? not many if any
your gunna need new rods, pistons and you could benifit from a cam for longer lift
plus, you need the manifolds, pipes for the filters, wastegate pipes off manifold, dump pipes (X2?????) cooler pipes cooler, your gunna need to hack up the front bar to fit the cooler, plus run pipes, you need to relocate the battery to the boot, move coil pack and a bunch of other shit so my advice is tell your mate to not be different, sell the turbine on ebay, and work the motor and if forced induction is still running throuhg his vains strap on a vortech, or one of them yellow terra kits
so unless you or your mate is a real good fabricator/welder with alot of good contacts this will cost you a mint, why fix it if it's broke???
supercharger
sorry no nothing about turbo but thinking of possibly fitting supercharger to my vn v6...what is yours and what is the power gain and r u happy with outcome...how much did this set u back
the motor should be able to handle 10psi stock if it's in good order and the tuning is really good. the list of things you put there arent all neccessary, for one, it has an internal wastegate so that eliminates your wastegate pipes, dump pipes are not an issue, that is just the leading piece of exhaust pipe off the turbine housing, you shouldnt need to move the battery because its a single turbo install.....you make it sound like its near impossible when we all know it isn't, try not to be so negativeOriginally Posted by CSL

yes teh vn v6 in the magazine your talking about they ended up spending roughly 20 grand to get that right, think of it this way old vn s1 engine is well worn by now and your gonna strap a turbo to the side of it if the engine is not in good nick something is gonna break even if it isnt it will still break i found some good tt conversions on the net one was going for around $4800 you may be better off looking at one of these kits and giving the engine a rebuild and ballence first
if i intercool my vn i will have to move the battery to the boot as there is no room for intertcooler piping otherwise... the bloke i boght my manifolds off said he was running about 14 psi for about 12 months on a stock motor and had no trouble at all... they are fairly low compression anyway.,..
i aint trying to be negative, all i am saying is that it is a very big job, and i dont want him to realize that halfway through, plus these engines wernt meant to be boosted so they will not handle that much pressure for that long, somthing will give, and yeah you do need dumpipe(s) made up like every other peice of pipe it needs to be custom, i.e tacked up in place then welded up properly, and if that aint a big job, then i love fordsthe motor should be able to handle 10psi stock if it's in good order and the tuning is really good. the list of things you put there arent all neccessary, for one, it has an internal wastegate so that eliminates your wastegate pipes, dump pipes are not an issue, that is just the leading piece of exhaust pipe off the turbine housing, you shouldnt need to move the battery because its a single turbo install.....you make it sound like its near impossible when we all know it isn't, try not to be so negative
//There Ain't No Rest For The Wicked...
haha tell your mate, 10psi boost will only get him in the 160rwkw range.....
Sorry to put out his fire..
Cheers

there is a fella on this forum who has a turbo v6 running 7 or 8 psi and getting 210 at the wheels...

He's got around $5000 to spend already ajnd that numbers only gunna go up while nothing is getting done to his car. There was a stock VR in Street Machine magazine running 12 psi so it is possible( Larger fuel pump) . Is it a better idea for my mate to go the whole haul and buy a second T28. Do you need duel throttle bodies with a second turbo??
i read somewhere but i can't remember it all. i read that with turbos a smaller throttle body will either give you more torque or more power.. i cna't remember... i am sure if you force it thorugh one throttle body you would be right.. $5000+, that should be unreal when it is done..
i have not heard of one person yet turboing a v6 and having it blow up. only people saying they reckon one of those engines would blow up if turboed. there is too many stock motors being turboed now and running fine to get all worried about doing the internals.. i have an AIC but the fella on this forum who is getting the 210 at the wheels just got bigger injectors and a bigger fuel pump so i think i might go that way too..

I was not refering to "vengeance" it was a VR that pumped 12psi same engine thats all. And it was around the 220,000k range. my mechanic today is taking the car to an Auto Electrician (Lost my license hahaha) today to have full diagnostic done on ecu then taking the inlet mainfold, valley covers off. My mates bought some yella terra roller rockers and high performance lifters to install. May change rods but **** tha pistons.
Has anyone actually turbo'd a vn s1 on this site?
there is a few people on this forum who have done it but i cna't remember there names... when i finally do mine i will post a few pics..
sounds good turbo vn always a different approach, tho dont expect lots out of the old buick vn's there not very advanced but ok
Cheers.

hey v6vengeance, there is a place that make turbo manifolds for the vn. its the same place that made the one for the actual v6 vengeance, they were stainless steel. looked expensive. ill look through my old mags to find the add. ill pm you if i find it ay
VeNgeance
Yeah its F.I.T.(Forced Induction Technologies) and it's very expensive.
