hi all ive been doing a fair bit off research on forged pistons but can not make my mind up on size.?
A: Should i go for standard forged size for rb25det,.?
OR
B: Get 20thou oversize forged pistons,.?
option A sounds easy thats if the bores are ok.
But then i can get it bored out the same size as the oversize pistons then i will have a nice smooth bore.?
if you can give me some advice that would be great.
Cheers
