sell it to a sentra owner...and buy a rwd SR

^^^ What he said....and if you do that and STILL want to rebuild the RWD SR motor there's alot to consider, sorta.

Assuming the walls arn't in bad shape (You have to check with a bore gauge!) Than you could just go ahead and hone the walls and not have to get oversized pistons.

You'll also have to check the bearing clearances and what not.

You should really do the research though.....there's PLENTY of info on this.

Its not hard, just takes time, patience, money, and the proper tools.

well im assuming that it would be cheaper if i just get the complete set with engine and trans and all accessories but how hard is to convert a fwd sr20 motor to a rwd sr20
