R31 Ls1 Conversion

[SLIDN31]

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.

Sorry forgot this was a Vis topic. WOW i though SA was the toughest with engineering! But they are actually about 245fwkw, S2 VY n VZ SS, not being a smart arse, and put out the same torque as my 25 got approved with.

How do you guys go about engineering? Do you have to under go seperate tests at a certain price per test? Chassis strength tests, lane changing tests, braking tests?

Oh it's an older one, not the 286kw one or whatever? (not 100% upto date with LS1 outputs in whatever forms)

You basically get scrutinised for everything from Emission controls, brake/drivetrain upgrades, engine mounting, frames, exhaust noise etc etc. IIRC as soon as its non-factory, non-family option - you go through the ringer.

I think more than a 20% or 25% power increase it gets tough and the other issue is the torque figures will be what will really hurt you.

EG. You can't engineer a LS1 into a torana or anything these days here. The VASS Engineer who did my car (26 into a HR) was telling me it happens often as people do the conversion BEFORE checking with a VASS signatory. They haven't signed off once since some changes were made a few years ago. Not sure what they were though, i didn't go into more detail on that topic at the time.

Cost/Effort wise it's a certainty you'll get a RB in, and cheaply simple due to the fact it's Nissan and it's bolt-in effectively with just a brake upgrade to the same or similar spec the motor came from.

Fken Victoria is seriously 15 years behind. The EPA laws are from 1992

Ah ok. Yeah we are the same when it comes to all the tests. You have to have papers and reports on EVERYTHING when you go for your inspection. I have a whole folder in my car that i have to carry around with me at all times for the police haha.

Yeh my mate said it wouldnt be easy but its do-able.... But like you said $$$$$. In total over here, it will be about 4k for papers, compared to 2k for the RB, not to mention RB's being a hell of alot cheaper. The set up i have will be fine apparently, the only thing is the clutch bleeder location.....a hole in the passenger side tunnel with an extension to bleed LOL
