discopotato03 Posted June 24, 2012 Share Posted June 24, 2012 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 . A .

Morgz32 Posted June 24, 2012 Author Share Posted June 24, 2012 I'll check, and I may seek out a engineer to see if I can get permits for it Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413144 Share on other sites More sharing options...
R31Nismoid Posted June 24, 2012 Share Posted June 24, 2012 What state are you in? I highly doubt you'll get a LS1 passed in Vic for instance. Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413163 Share on other sites More sharing options...
Morgz32 Posted June 24, 2012 Author Share Posted June 24, 2012 In Perth dude, I just wanna know if there are kits available if car gets stickered ill track it Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413277 Share on other sites More sharing options...
StevenCJR31 Posted June 24, 2012 Share Posted June 24, 2012 (edited) 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 Edited June 24, 2012 by StevenCJR31 Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413283 Share on other sites More sharing options...
R31Nismoid Posted June 24, 2012 Share Posted June 24, 2012 In Perth dude, I just wanna know if there are kits available if car gets stickered ill track it 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: http://www.skylinesaustralia.com/forums/topic/187852-r32-ls1-conversion/ This thread has no real useful information (but it's R31 with a LS1): http://www.skylinesaustralia.com/forums/topic/355725-ls1r31/ Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413304 Share on other sites More sharing options...

Simon-S14 Posted June 24, 2012 Share Posted June 24, 2012 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 Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6413406 Share on other sites More sharing options...
JonnoHR31 Posted June 24, 2012 Share Posted June 24, 2012 http://forum.r31skylineclub.com/index.php?topic=143701.0 Best way in Perth is to just drive it until it gets stickered and then get permits for the work done.

FordyR31 Posted June 25, 2012 Share Posted June 25, 2012 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.

rb20-into-mr30= Posted June 25, 2012 Share Posted June 25, 2012 (edited) 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 Edited June 25, 2012 by rb20-into-mr30= Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6414570 Share on other sites More sharing options...
Rolls Posted June 25, 2012 Share Posted June 25, 2012 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.

bozodos Posted June 25, 2012 Share Posted June 25, 2012 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) Link to comment https://www.sau.com.au/forums/topic/403271-ls1-into-r31/#findComment-6415730 Share on other sites More sharing options...

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

kitto Posted June 25, 2012 Share Posted June 25, 2012 Garage 7 would certainly be able to help with doing the conversion. Declan has done much much harder conversions before.
