These are using a LS2 intake and Fast 90 tb.

with more tuning and the cut outs....i will be pushin close to 550 with the LS2. Just cant justify $800 for 20rwhp. If i am gonna do that...it will be $800 for a 200 wet shot

Everybody I've known that has put on the LS2 has lost power. Even C6 owners are gaining power by swapping on the LS-6. The TPIS oval intake/TB is another option, but equaly as expensive. Personally, I'd find a used FAST. Sweet numbers BTW. I'm fixing to head down and have Allan dyno tune mine. Should be fun.....
