i got a b18c5 block with cranck and itr rods.

should i run oem pistons or forged ,looking to get 12.5 compression for i will be draving this car 3 days out of the week . And also my altitude here is close to 5000 ft.

and also for a low budget build up.

 

well if your block came with pistions you may as well leave it alone. Mill the head .030 or .040 be sure to check clearances ect. build head basics springs, retainers, and high comp valves. I suggest you sit down and decide on what you want for your setup.

If ur just looking to go the piston route Wiseco JE and I think aris makes 12.5:1 pistons in an over sized piston 81.5.

 

dont forget about toda pistons, they are worth the money believe it or not. They are forged, but they run the tightest clearance available on the market for piston to wall clearance.

 

anyone?
