There are many routes you can go.
Buy Skee's built B18c5 and spray(best HP for the buck)
Ls B18b1 non vtec precision turbo, inline pro mani, custom downpipe so you still have A/c, greddy boost controller, the tune, approx 290-300 at 14 psi not to mention the intercooler Bov, wastegate, piping (ouch)
JDM GSR B18c skunk2 intake,header, no cat, tuned ( should be fast)
Average guy cant afford the K swap
