i'm doing a b20 vtec build as we speak, i'm putting a b16 head on it, but the question is can i run a pritty high compression piston and still run a 75 shot of nitrous reliably????? or am i better off running low compression and calling it a day. my goal for the motor is to have 230hp on motor and 300 on NOS. and i dont wanna go forced induction. let me know what you guys think.

 

unless i am more tired than i think i am, the b16 head has a larger chamber actually lowering the compression a little. so you should be able to bump the compression up a little.

may get a better answer in the fi forum. may want to ask to move it.

 

What is your definition of reliable? 230hp NA is already asking for race gas and a min of 12.5 c/r.
