Its gonna be a 2.3l turbocharged SH-AWD four cylinder.

i want to run all motor what can i do to make the horsepower of my car greater without swapping engines and turbocharging it. and how much hp would the things u tell me give.

Right now i currently have a 92 civic sedan with a skunk 2 exhaust, a 4-2-1 header, and a cool air intake on a d15b7 motor. I am looking for suggestions as to what more can i do to it, besides turbocharging it, or replacing it to improve the performance i got out of it.

I want to know what models of the honda civics come stock turbo.
