try the NA forum

For big NA power, you'd need cams, valvetrain, maybe higher compression pistons, etc... + your basic boltons, clutch, flywheel, pulleys...

question is, how much money do you wanna spend?

There is a lot of material on this around here. Do you know about the search function? From my many hours of post reading, I conclude it will cost a fortune (many thousands) to run 13's NA. Then your tranny will break from drag racing. Nitrous is the best bang for the buck at around $500. Maybe bang is the wrong word. I use a ZEX kit.
