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.

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.

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.

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

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:

Mad machines, the lot of them! :worship:

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

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

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...

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

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 :yes:

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.

    • I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box
    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
