Okay guys I need your help Ive read all I can on here and had a few questions. I'm going to get my ls6 mani modded to house a 90mm TB and I was wondering if the nick Williams TB would work with the tpis 90 mm snout? is there anyone that can port the ls6 mani in the areas that it can be ported if so who? Thanks for the help everyone.

 

For the money you're going to spend on the 90mm opening ($300 I think), you can sell your LS6 intake for $300-$350 and buy a FAST92 for $600-$650. That route is better for two reasons...1. you don't have a hack job intake making your engine bay look like crap...2. the FAST intakes come apart which makes porting them much more effective than a LS6 intake which is one piece.

 

For obvious reasons the fast is better but wont benefit me in any way with the setup im going with. I wont see upwards of 6200 rpm sense im an auto so the ls6 flows just fine for my application just need to know the questions asked earlier

 

the NW should work just fine.

 

thank you for the fast reply

 

fyi, here's one for sale:
