Got my b16 head, GSR block and OEM headgasket for super cheap. Been looking for internals. Decided with Brian Crower springs and steel retainers, Ferrara 5000 series high comp valves, and sk2 stage 2 cams. As for the bottom end, I'm doing forged rods with Nippon p30 pistons, balanced and micro polished crank . Does anyone have experience with this exact setup? Just looking for opinion's

 

I would go with pr3 pistons..but that is just me. I have almost same set up except ls crank eagle rods and blox vt.

 

Why the pr3's over the p30's?

 

Anyone?

All of your answers to any question you could possibly think of is at your finger tips. Have fun learning

 

Aftermarket rods use floating wrist pins which require the pistons to have wrist-pin locks. P30 pistons do not have pin locks. You will need to either (1) use stock rods with your P30 pistons, (2) modify the P30 pistons to accept locks, or (3) modify your aftermarket rods to a press-fit pin configuration.
