V8 conversion legalities

Post by sudso »

Can a V8 still be legally put in a non V8 4wd under the new Code of Practice?

I have a 350 chev with a T350 tranny destined for my old HK Prem but now I would rather build up a bit of a 4wd beast using it. Was thinking of an extra cab ute.
It is an unleaded motor.

I suppose what I should have asked is:
Does it say anything about it in the Draft of the Code of Practice?

Either way it would still need to be engineered and approved.

i was actually talking to the RTA yesterday about this in regards to a 575 into a vt commo, and this is wat they had to say

Any engine mods or changes you get like this you have to get an engineer to hear about first and work out what can be done. Then once thats all approved and ok, you can go ahead (and get the engineers report/certificate afterwards) For the biggest V8, theres no straight answer.

Apparently a lot of people put a stroker kit on a 355 or 388 in the 5L.

He said that there will be new peramaters coming in in the near future (could be a matter of weeks).
Basically, the formula is: (any car weighing over 1100kg stock goes by this)

Original weight X 5 = Maximum capacity in CC's

So, a VT weighing 1500 X 5 = 7500 CC's max, or 7.5 Litres.

This is a guide to go by and the formula which will probably be taking effect in the near future. It is not published or written anywhere as it is still being drafted.

hope this might be of some use.

and I believe part of teh Draft COde indicates engine conversions certified under the COP cant increase output by more than 20% from original. Thats to be certified under the specific code, doesnt say it can't be done.

And I was speaking to a 4by workshop proprietor in Adelaide today.
He said he asked the RTA at Regency park about lifts and other mods, how far can you go now etc. etc. and they told him you can basically go as high as you want and whatever engine you like but it must come here for inspection and approval. Wont be legal until its approved as long as the mods are done properly and not make the vehicle unsafe.
I've heard they are pretty reasonable at Regency with regards to mods but they are a bit stricter on car mods.
