Nark/Draven: i have sussed it out befdore.. it is all legal if it is NA... but a 13b with a turbo is not legal..
Yeah i do have a TA22.. in nsw, they are my number plates.
I am prety open as to the form of the engine.. but most prob a standard 13b is preferable. If i dont go down the rotary path i will be looking for a suitable 4 cyl either with forced induction or a testbed for a conversion. I was thinking a 3TGTEU but i believe they are getting on now so i was also thinking 3S.
