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

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:

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

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 :cheers:

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.

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!

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
