OK I Have a B16a2 with bottom end blue printed and balanced with ctr pistons the top end with a mild port and polish with crower valvetrain,intregra type r cams, aebs intake manifold, apexi gt header and 2inch exhaust. what else could i probably do to this motor to make more power. It feels a little slow for everything thats in it...... anyone else knows anything????

 

ever tune it with all the work you have done? what ecu you running?

 

2 in exhaust is probably choking it off pretty bad. You should be at least 2 1/4, maybe even 2 1/2 with that set up
