Well put I just got a few questions and my .02 remarks. I never priced any of these before, what do they usualy run? Ah man you can't do it with 45's I would do some porting on the intakes as well. Keep in mind it's VERY easy to take to much material off aluminum. Are you saying Bobs also adds 20-30 rwhp also? Thats not to bad A ported E6 I think is 11 rwhp but don't quote me. The reason is a 2.3T air sensor (VAM) want support much over 300 hp. I mean like less than 5-10 over at best. I'm not sure I would go over a 50 shot my self and only to help off the line with turbo lag. Thats just my feelings on this.
