#346437 why dont you try compression calculator that can give you a good idea of how to start http://www.zealautowerks.com/bseries.html

see how much you can get by only replacing your pistons to (PCT) b16b pistons, but i think you might have to shave 1mm off each side where the piston connects to the rod search and ask about it i think this can give you good torque

#346448 Making horsepower on all motor build is pretty tough to do and expensive. But with the right parts it can be done.

The biggest power gain, bar none, is head work. Tons of hidden horsepower to be unleashed from the head.
