.25mm overbored 12:1 compression forged pistons (probably JE) and a 50-75 shot nitrous on skunk2 stage 2 cams? wondering if i'd be under or overcamming this setup..

 

high lift cams?
high compression?
and nitrous?

is that a good set up?

what engine management?

 

hondata s200.

and i don't know if its a good setup, that's why i was asking

 

those cams should be just right for that setup , but I wouldn't go near NOS.

 

is it true that CTR pistons yield a 12.4:1 CR in a b18c motor?

 

Only one way to find out.

Find your crank pressure under stock conditions, and then do it again with the S2/12:1 conditions.

If you have raised your cranking pressure above 25% you are undercamming the engine. If you have dropped cranking pressure you are overcamming the engine.
