itr .25mm over for my gsr block or itr .30 over

 

Same as every other piston install (after honing your block .25 over), Chiltons manual is your friend!

 

wow i hate when ppl tell ppl they can hone there block to .25 over NO you need to bore at a machine shop then hone it. if you dont know what your talking about dont put your 2cents in. im sry but i dont what this kid to go buy pistons get a honer from the local auto shop and try making these pistons work.

 

yeah gotta bore it out first>>> then hone. how im doing mine

 

I'm having this done too but im not boring because the walls were good and just needed to be Honed.

 

first off you need to bore the block to met the specs of the pistons, the have the pistons pressed on the rod(machine shop), put the bearings, dont forget the lube, clock the rings put the ring compressor tape them in to place, tq the rod bolts make sure the arrow on the piston is pointing to the front (driveside)...done
