R31 Ls1 Conversion

[v-spec2]

Hey guys , I'm planning to do a LS1 conversion in my series 3 R31 skyline. So i was wondering if you guys knew anything about the conversion or anyone who has done it? I plan to complete this project by mid next year if anyone could give me some useful information it would be great. I have already used the search criteria and could not find much information.

you will find more info on r31skylineclub.com

Thanks Paul , I'll have a look on there.

im sure its been done many times before but as with any major engine conversion u will usually not find any two the same. thats the thing about it. you will spend many hours working things out and finding ways around things and finish with a car thats quite unique. of coarse when its a more simple conversion (say.. putting a 30 bottom end in a 33 or rb into a smaller nissan like a silvia) it may not take as much modification or innovative thinging as putting a big v8 in a completly unrelated chassis.

but im sure you will work through it. its far from the weirdest conversion ive seen. a hyundai excell with an ecotec engine with a huge single turbo hanging off it was a bit of an eye opener for me. the way the had to ...."adjust"..... the floor pan to suit rear wheel drive was lets just say, interesting lol

I'm just thinking of the fabrication that its gonna in vole in with the engine bay. But it is a project car so i should be expecting something like that.

[tm_r33]

well yer there will be some fabrication i imagine. u will have to work out which crossmember and engine mounts and then if u run the ls1 gearbox u will have to work out the gbox crossmember and perhaps custom tail shaft. or if u wanted to use a nissan box u would need to find some sort of bell housing adaptor.

treat is as LS1 into VL IMO...

off topic - but do you have pics or a link - sounds interesting

I assume this is just a track car or similar?

There is little to no chance you will legally get that engineered/registered.

Thread revive.......Im currently doing this now for drift. also you can get it engineered, already looked into it :-)

[LKC]

I dont know what stage you are currently upto but if you have pics please post. I would love to see.

I'll start the list of things you need to do in order to successfully complete this conversion:

1. engine out

It's an interesting idea but probably worth doing a fair bit of research and running some figures before getting stuck into it. It'll most likely cost X times as much and take Y times as long as you originally budgeted for...

Some potentially helpful threads:

• SAU: BezerkR32's R32 Ls1 Conversion
  
• LS1: Walt's FD RX7 V8 L98 6 Litre circuit race car
  
• LS1: 1971 LS1 240Z aka 570Z
  

Mad machines, the lot of them!

R31Nismoid, the 240Z is mod plated and street legal in QLD ... good luck trying to get that done in VIC

Which VASS was it that said they would approve a 5.7ltr V8 into a 1300kg R31?

[Curmi]

seen a hilux ls1 engineered drift car looked awesome i so wanted it.

hi,

Just found this thread and thought if you were in need of some help i know a fella that did a ls1 conversion when he was working in western australia said it was a good job to do, Give Pete at Supreme Tuning a call 56299321

He can help point you in the right way if you lost

[SLIDN31]

thought i would throw these in.....keep forgetting where i have posted lol

Mine finished and being thrashed as we speak lol. Yeh a mate who is an engineer said he can approve it for me, basically the same as my 25det went through for engineering...

Not sure what a VASS is.....Pretty sure you can get anything engineered, its just how much your willing to put down. I got my 25 done very easily, just people are not willing to spend 2-3k on a shitty r31....but i like mine.

Not sure how to do these multi quote things, sorry for this.....built mine in 2 months....only 3k over budget

You aren't from Vic - So unfortunately what you can do in your state has no bearing on this topic at all.

So as i said earlier, I'm very confident you'll never get a ~300kw LS1 registered into a R31 (factory of what, 140kw) in Vic which was the conversation being had.
