Hey guys my friend has his 95' B18C1 block pulled apart right now. He is going to turbo the motor. Well we had some 96' LS pistons laying around that our friend never used. Can we put the LS pistons in the gsr block to get lower compression? Also will the LS pistons fit on the gsr rods, or what other rods will we have to get? He is getting supertech valvetrain put in the head, so that should be fine, but are wondering how the LS pistons would be? Any info is appreciated.

 

yes all b series pistons have the same bore, except the b20, same pin width too.

doo it !!

just remember that the stock ringlands dont like any detonation!!

 

Since you have everything apart, get some forged pistons.
i dont trust oem pistons under boost.
do it right the first time, this will save you time and $

 

im doing the same thing with my turbo gsr .i got a killer deal on some wisco pistons they were for an ls i'll post the part number later today but i have no clue yet want the compression will be on it .

 

get the part # and go to the wisco website.

 

i tryed cspeed but i dont thinks it right. and its throwing me off alittle.

 

is it a dome piston or dish
look at the cc hight should have a negative number
