i'm about to get a project engine...and just out of curiousity i am wondering if somethin can be done. i know you can bore an sr20 out to accept 300zx pistons. can you bore out a ga16 to accept sr20 pistons? or are the walls too thin? what would it be...1700..1800cc's?

I'd like to know also, but I'm afraid the walls are already pretty thin. Robert Legre already did this you can read the whole thing here http://www.mathermotorsports.com/html/timmotor.html

Incidentally, although the original compression ratio was rated at 9.5:1, the true calculated ratio turned out to be 9.59:1. Most automotive companies are a little optimistic, but Nissan appears to be a little pessimistic in its calculations. I settled on an increase to 10.5:1 compression and a bore increase of .040", as the cylinder walls didn't look thick enough to accept a larger bore increase. Displacement increased slightly from 1597 cc's to 1639 cc's.

I don't know how much can be removed or how big the sr20 pistons are but if it can be done someone let us know.
Hope this helped
Josh
