I was thinking of putting my P72 pistons on there with the B20 rods, but then I remembered that the B20 sits at a 2.0 while the GSR is a 1.8, will this matter?? Does the 2.0 mean that the piston are wider?? I dont beleive that they are interchangable, but I still havent really found out.
p27 pistons wont fit. The B20 is an 84mm bore. Also when you change the head, he compression will change.
www.c-speedracing.com if you click the how to or diy or something like that, you can match different heads with blocks etc. and it will give you the compression and the displacement.
