|
|
I rang the QLD D.O.T about conversions of larger engine capacity's to a vehicle, and this is the info i got. I thought it would be usefull to share this for people undertaking engine conversions in Queensland. I should also point out that this information refers only to a "4 cylinder" car.
For a vehicle that is naturally aspirated as standard, and has a total weight of 1100kg or LESS, the formula is...
Vehicle weight in kg's X's 3
e.g TX sedan approx. 950kg's X 3 = 2850cc = 2.8litre max.
For a vehicle that is naturally aspirated as standard, and has a total weight of 1100kg or MORE, the formula is...
Vehicle weight in kg's X's 4.82
e.g TX sedan approx. 950kg's X 4.82 = 4579cc = 4.6litre max.
For a vehicle that is naturally aspirated as standard, and a forced induction type engine is fitted.
If the total weight is 1100kg or LESS, the formula is...
Vehicle weight in kg's X's 2.5
e.g TX sedan approx. 950kg's X 2.5 = 2375cc = 2.4litre max.
For a vehicle that is naturally aspirated as standard, and a forced induction type engine is fitted.
If the total weight is 1100kg or MORE, the formula is...
Vehicle weight in kg's X's 4
e.g TX sedan approx. 950kg's X 4 = 3800cc = 3.8litre max.
I was told that if a higher capacity engine was fitted than these, it would not be worth the head-ache. As an approved engineer would have to scrutineer every milimetre of the vehicle, this would have to be done after every modification to meet the safety and legal standards, and the 'red tape' involved would take approx. 6-12 months. In which time your money would have been better spent elsewhere on a more legal conversion that could be driven on the street alot more quickly.
Cheers,

My initial question for him was, "Can i legally put an RB25DET in a 180SX ?" His response was what i stated in the post. So legally, yes... A VG20ET can be fitted to a Gem. He pointed out that as long as the complete brake system from master, booster, rotors, calipers and so forth were fitted either from the donor engines vehicle (would be the most encouraged) or better.

P.S Dont be afraid to ring these guys for info, he was more than happy to help. He also pointed out that it was about time younger people were asking this sort of advice from a professional before jumping too far ahead of themselves. |
