Regarding NSW RTA

coops has a reasonable point there.. As the tare weight is recorded with the original A12 engine intact, if u then fitted the significantly heavier FJ to the mix.. wouldnt this bump the weight up on the weighbridge.. therefor letting u fit the bigger engine?

Or is it the tare weight for the original vehicle... REGARDLESS of modification?

Good topic by the way.. sheds alot of light for ppls answers

thanks for that daveman, im very happy now lol.

for forced induction it's 2.5 x kgs = cc's allowed
for NA it's 3 x kgs = cc's allowed,
this rule is for passenger vehicles
ie: 1200 coupe 729kgs x 2.5 = 1822cc,

I remember hearing something about the legality FJ20 turbo motors....

The way the story went was that because the FJ20 (being cast iron block) is so much heavier than say an SR20 & the calculation for the size engine you can put in is based on kerb weight with the engine included, this gets the FJ20 past the post.... Just.

Can anyone else validate this?

Does anyone know the formula...?
Something like kerb weight x 1.5 = max. capacity for turbo motors ( x 1.8 for non-turbo)...??

That's it wardy, the only way to do the 2.0ltr turbo thing "legally" here in NSW as i understand it is to get an engineer to approve and certify it cause it is WAY outside the rta's guidlines for power to tare weight ratio's.

You would be hard bloody pressed to find someone to do it though cause it's their ass!!!

That is the ONLY way you would get one registered here in NSW. Spoke to my fiance's cousin who is a mechanical engineer and he said there are no tricks or ways around it. Just cannot be done.

Any one in NSW who has one registered on the road has a very friendly and trusting engineer as a friend or member of their family, or had it continuosly registered for the past few years.

Dunno bout other states though.

went and saw me engineer today just for ####s and giggles And put the hard word on him to do a SR turbo conversion in my ute and he used these words exactly " i dont think so " in a sarcastic way!!! so thats a no no for me..haha

If you read the whole thread I said earlier that you can engineer them in Vic. Vicroads don't work on a formula like other states, you just need to convince an engineer that it's safe.

Hey jonboy can ya post some pics of ya setup?? cheers mate

my standard internal ca18det makes 313rwhp on nos and runs 11.40s .the motor has been in car for over four years and never had any dramas
