Sounds like a solid setup. I see no need for the genx heads and intake if your going to boost it, money better spent on suporting mods for turbo. If you have the 799 heads those are the best flowing cathederal port heads from GM. Plenty of guys doing 1k hp on 317s, more or less same head as 243,799 with diff chamber size. Now if your going for every bit of power or money aint a problem then go all out lol.
What you say is true , when i think about it boost will work his way with this heads or aftermarket ones , i still have stock 4l60e which won't hold to any thing higher , time to get TSI th-400
thanks bud
