Ok im building a friends motor and was wondering if i would have to do anything to the pistons to make them fit and have clearance with the crank? Or could i just get them pressed on the gsr rods and put it in the block with no problems?

 

bump.

 

?

 

whats the block bored out at stock bore i think is 81mm sometimes people bore them over so they get a perfect seal with the rings. oh and what do u mean have clearance with the crank? i have a nice new set of ctr pistons im trying to trade for lmk if interested.

 

When the pistons return down to the bottom of the block will it hit the crank while it turning..


Heres a pic of what im talkin bout.

 

Thanks for the pic but yea i think ur alright there. i dont see y it wouldnt clear. they make the pistions to fit more than one motor.

 

no, itr and gsr share the same stlye crank and rods

 

Alright ill just get them pressed on and install them. Thanks.
