what pistons should i use in b18a1 for a all motor build
b18c1
b18c5
b16
or what

 

what bore size do u have?

 

You should buy some ctr pistons

 

piston selection is diffucult, it all depends on how extreme you are wanting to go. This also depends on:

1. bore size

2. rod selection

3. crank selection

If you exceed the piston to deck height with using a set of pistons not compatible with the rods or crank, the pistons will literally run into the head. IMO I would go for a set of p30s they're a very good piston for the money, and depending on your application can yeild some very good numbers with the right tune, also you will run into very few problems running these pistons, as they are not as high compression as the ctr or even the itr by a very small margin.

 

im rolling my b16 w\ some wiseco high compression pistons,
there pretty good, only about 530dallors on the net,
