A&Q about 350Z
Q:
What car would you beable to swap the RB26DETT into with none or minimal mod to the car?
A:
How about an R32, R33 or R34 GTR Skyline? It should bolt right in.
With a little more work it will go into the lower spec skylines, the GTS-ts and GTs.
Anything else and you have to start making serious modifications.
A:
I once saw a Holden in a New Zealand rag with a rb26dettand 6 speed GETRAG. Alot of work to put in any car. If I were going to do it in anything other than a skyline, it would have to be a smog exempt Z car (250Z?) You could get the front done in fiberglass, and build a half tube-chassis around the engine/trans. Easier than cuting into the unibodies and rewelding sheet medal i think
