NICK WILLIAMS 90mm THROTTLE BODY
NICK WILLIAMS 90mm THROTTLE BODY quick question, will a NICK WILLIAMS 90mm throttle body fit a stock intake manifold on a 2002 LS1 T/A, are there any noticable power gains.
Quick answer... no. The stock tb is a three bolt mount and the 90mm tbs use a 4 or 5 bolt design. The tb on the stocker wasn't the restrictor. The opening on the intake is. TPIS sold one where they cut off the inlet and grafted on an oval one with a different tb. I believe it picked up 12 or more rwhp. Really need a 90mm fast intake to go with a nw 90mm tb.

As has mean mentioned TPIS offer a 90mm LS6 intake on an exchange basis. They offer their own 90mm TB, round or oval.
