IF you're going to boost to over 12, get a good management system.

Guy I met was running 18 lbs(around there, anyway) with all stock internals, but because he tuned t well, he's not had asingle problem in close to a year now.

I would say LS Vtec Turbo. Just don't boost the shit out of it right away. Start off at like 8psi. Get used to it. have fun with it. If you need more...well...then up it a bit. I know its extra work, but you get much better results in the end.

What kind of head work are you looking to do with whatever you decide?
