Go with an angrier cam, or run 1.7 rockers too.
A custom tune is a must. That will make or break your build.
Dont spend the money on a ported TB, do that yourself, or have someone on the forums do that for much cheaper.
Only need for a TB spacer is to tap it to spray.
Lastly, and most important. DO NOT BUY AN INTAKE SYSTEM. Buy a big ass cone filter, and make your own.
