Im preparing to rebuild my engine and need some help with picking parts. for one thing, every manufacturer lists pistons for the b20b, but i cant find any that say b20z also... they are the same bore, so they should be the same right? so then it comes down to brands, im not really sure what kind of pistons or rods to get. the goal is somewhere around 10:1 compression ratio. the block will be decked so will affect cr slightly. i will be bolting on a jrsc with either the 8 or 10 lb pulley and im hoping for 250whp. opinions on what to get??
