piston and bore opinions
hey guys, this is my first turbo build, im building a b18b1, stock sleeves, good rods, and forged pistons, a little porting, all Aft. market valvetrain, with a t3/t4, 15-20 psi. shooting for a reliable 300 whp. i would like some input on affordable forged pistons, and which bore to use, (i have stock bore) and what compression ratio to use for this set up. thanks guys.

Re: piston and bore opinions
my personal opinion i would take .020 (.5mm) over, because all pistons arent the same and some p-w clearances are a little different.
when i worked at a local machine shop in high school, we didnt order pistons for the block, we bored/honed the block to the pistons.
that is just from my personal experience.
as for what pistons to use, i have used these 3 in this order. SRP, JE, CP.
the srp's were in my first engine. worked very well. b16 low boost.
the je's were a little more aggressive build. and lasted the small turbo and lasted with the t3t67.
the cp's are in my current build. it is over 700hp, over 30+ psi and holding well.
all compression ratios were 9:1 which should suit you well if you are doing a pump gas build. my next will be 10-11:1.
hope that helps.
