Ls1 Into R31

[Morgz32]

Hey guys

I got a series 3 r31 and looking to do a ls1 conversion, jist wondering if anyone knows if the is a conversion kit available and where I can get it from or what is needed to drop one in, I know there is s13 kits etc but have not seen one for r31

Cheers

If its a locally built one with that 5 link rear end ...

You may want to be sure that a 5.7L engine into a normally 3L car will get approval because I don't think allowable upgrades are based on the weight of the car any more .

I'll check, and I may seek out a engineer to see if I can get permits for it

What state are you in?

I highly doubt you'll get a LS1 passed in Vic for instance.

[Morgz32]

In Perth dude, I just wanna know if there are kits available if car gets stickered ill track it

[StevenCJR31]

well done on thinking outside the box! anything has to be better than a NA RB30E but doubt that you will get it passed without upgrading the brakes and other things too, gonna cost ya alot of bucks as its unlikely there will be an off the shelf fitting kit available

You might be right over there, they have a system that is at least reasonable

There is no off-shelf kit that I'm aware of, it'll be all custom fab work as there aren't that many LS1s in R31's to begin with, I recall seeing maybe 2 or 3 cars with one in them over the years and that's about it.

This is probably as good as you'll get info wise:

This thread has no real useful information (but it's R31 with a LS1):

Yea got s13 front suspension set up with 33 calipers and bc coilovers

It's different and well fun and I've seen none

Thanks for help so far

pick up the latest drift battle mag.. local SA guy has his car featured in there. LS1 into a 31. goes pretty well.

Failing that speak to Jautech in adelaide, they did most of the work on it

Best way in Perth is to just drive it until it gets stickered and then get permits for the work done.

No one makes anything for 31's so it sounds like it will be a custom job

even if it has been done before. There is hardly a market for it.

i spoke to the guy in s.a with this conversion, all that was needed was custom tailshaft, gearbox crossmember and engine to mounts were custom. I think he had standard engine mounts from the crossmember part. very easy from what i saw. I am doing this conversion myself on a r32

there is a place here in sa that makes mounts for ls1 conversions, he is on ebay. best bet would be mounts for the vl 6 cyl range.

hope this helps

In an R32 you can go up to a 7L NA engine or 4.5L turbo charged if you get it appropriately engineered.

I imagine an R31 is slightly heavier/the same so I imagine similar limits, I read this on the application to modify vehicle regulations.

[Simon-S14]

LS7 anyone?

factory 377 kw motor lol

[bozodos]

got a spare 15k? lol.

OP: Could be worth enquiring somewhere like the Castlemaine Rod Shop as they do a VL LS1 kit (not sure if there would be any common parts or not)

Not quite correct... It'd be around 6500cc (maybe less, depends on model).

VSB 14

Either way each state then carries it's own laws on the matter so it could be less again (or impossible).

Vic being a VASS Engineers, I've spoke with some a few years back and i did ask a similar question. They said no way would they be letting an injected V8 pass in a lighter car than it came with, especially given kw increases... So as i said earlier it comes down to the state you live in, and knowing the laws and contacting the engineer first to find out what they will need before doing it. could even depend on the engineer you get and if they are willing or not!

garage 7 in S.A wouldnt be able to help would they? i got all the stuff i need for s13 front set up from them they seem to know abit about 31's you dont know the guys name on ebay so i can search him or what i search under??

all this helps guys cheers!!

[kitto]

Garage 7 would certainly be able to help with doing the conversion.

Declan has done much much harder conversions before.

[Simon-S14]

as far as conversions go... its an easy one

[bozodos]

please post a build thread if you go through with this OP
