V8 Conversion For R32 Gtst

[Black Widow]

Hi Guys,

Well in the next few months i am hopefully going to be the owner of an R32 GTSt after an extended hiatus from the Skyline scene.

What i will be wanting to do with it, is eventually do a V8 conversion, now i understand that getting this approved through the RTA may prove difficult (even impossible) hence why i am wanting to research teh topic well before i go down that path.

Also, for anyone that has done this type of conversion, what's the best motor? I'd be looking at a Holden motor so would it be LS1/2/3? L98? I could also potentially have access to a "cheap" crate motor from the states, but not sure of what is available there, and would at this stage prefer to keep it local.

I know a few guys on here have done it, but i am under the impression they have only been used as track cars, nothing for street yet?

Cheers

Nick

Good luck with it Nick, it would surprise allot of enthusiasts when you take off from traffic lights and it grumbles like a V8

Have you read all the threads on this available through search? E.g.

"LS1" and "LS2" should give lots of results.

[blind_elk]

Why not keep the engine "in-house", ie a Nissan engine - VH41 or VH45, far superior to the horrible lump of US cast iron.

[mad082]

since when has the LS engines been cast iron? they are an all alloy engine. the last cast iron v8 engine holden used died out about 10 years ago.

I have followed Bezerks thread yes. And will continue to do so.

As for that other thread..starts off ok but then turns into a "Could an RB do Bathurst" thread...

Never really considered it to be honest. I'm fairly keen on doing an LS* conversion as i'm familiar with the motors and like the way they perform

[Altia_R34]

that be sick many people in Adelaide have done it

Thanks mate, i'm looking forward to it....

[mad082]

are you going to have a big squid hanging off each bank? cause the rumble of a v8 plus the whine of a pair of hairdryers would really get peoples attention

[Black Widow]

Not sure what you mean by squids?

At this stage i'll be keeping the motor NA...and then later down the track it will be gaining hairdryers.

I'd like to see someone get 300+Rwkws from an aspirated Nissan V8.

the Lsx engines are by far more compact than the VH engines as well.

squids = turbos

squids = turbos

Thanks man.

But no, will be NA for a little while..then eventually will resort to whacking some boost through it

We're presently in the process of dropping a VH41 from a Cima into an R32 race car.

We'll be using twin turbos from an R32 GT-R to give it a bit of extra oomph.

So far the issues we've run into are the firewall and gearbox adaptor. The firewall is going to need a little massaging and the adaptor is going to have to be fabricated to handle a 25DET box, nothing that won't be achievable.

The turbos will end up facing high and forward and we'll need cutouts on the bonnet to make them fit, but we'll have about 2cm on either side for strut tower clearance.

I think an NA version is possible for a road car but the LS is a better option for you as there are quite a few threads available on the builds.

Good luck with the project.

if i recall someone did a nissan v8 into a gtst a few years back on this forum... cant recall their name... but i tihnk it was a 4.5 or so.

so its been done.

That would be because they are still using pushrods to activate the camshafts, rather than multi-valves and twin OH camshafts.

It's about time GM brought their technology into the latter part of the 20th century, before they even consider the 21st century.

LS engines have excellent engine weight/power ratio and as mentioned above engine size/power ratio. There're even lighter than all the RB engines and have much more power potential.

Pretty good for old ass tech. IIRC the low-tech LS3 sh!ts all over the the DOHC hi-tech BOSS in the FORD.

The number of camshafts doesn't determine the quality of an engine.

Must be a QLD thing we call em snails here....

Do you know what a Slab is marc??

If you can afford it get the LS7...427 cubic inches will fit anywhere a LS1 will fit ,around 500 neddies ...boooyah!!!!

No. But they've been supercharged to make that much, and relativly cheaply at that. Yes, there was a R33gts-t on here that had the VH45 conversion done, in QLD from what i remember. He ended up running a superharger on it, running methanol fuel, and some other fancy jazz. from what i remember it was in the low 10's at willowbank.

And yes, i deliver. spent a while going through my SAU history, but found the 20 page thread about it

linkie

enjoy.
