i have a set of JE pistons , currently rebuilding my engine

on the spec sheet, its says to set it to .0040 , but my engine rebuilder told me i would probably need more clearance , cuz i told him i wanna run 30psi and aiming for around 500whp

any idea how much clearance i should use ???

thanks guys !!!!!!!!!!!!

 

are you asking for ring gap or pistion to wall

 

im not sure .....

what about if you tell me both ???

pistons clearance and ring clearance , its b18c1 pistons , 81.5mm

thanks man

 

up

help a brother out

 

.005 will probably give you piston noise when it is cold. Call JE directly and ask a tech

 

Let us know what JE told you just for other's future knowledge

 

Not to jack the thread, but fixing to be in the same boat, Sleeved block, new pistons, ect........ Is there a way for someone Building there own motor to ckeck piston to wall clearence?
