i know a person selling a set of endyn roller wave (wiseco) pistons for a b16a. they are 84mm and yeild a 9.5:1 compression. will these pistons work in a b18c resleeved to 84mm or b20 block that is already 84mm? the head is from a 98 jdm type-r. so does anyone know if i can use these?

 

??

 

Yeah, they will work. But your compression Ratio will be higher then 9.5:1 with a GSR head.

 

b18c5/b16a head + b20b block
b18c5/b16a head + b18c1 84mm block

does anyone know about where my cr would be?

 

once more

 

Gotta find out more about the piston dome displacement CC's

 

You definately need to to CC the motor, my Endyn RW psitons were supposed to be 9.7:1 but in reality were 8.9:1. B series pistons are interchangeble.SUpposedly Endyn and some other companies don't have a B16A piston but give you a GSR piston instead. Hearsay so.

 

it says compression ht is 1.180
and bore is 3.308.
need any more info.
