I have already thinked about it. However here in Portugal SR20DET are not very easy to find.
Even the A14 are very rare and the A15 are inexistent.
I have thinked about the 300ZX V6 biturbo Engine and i tried to buy one. I think it can fit very tight. The junkyard price was something like $5000 with a broken intake manifold for the complete engine, ECU, Gearbox, endshaft, etc..., Quite expensive!!!!
That will be a hell of a car, over 300HP/750Kg.
I am now searching for something less expensive. But i think that the CA18DET or the SR20DET could be great.
