Default LS6 intake with NW throttle body

i have been trying to find the specs on the size of an ls6 intake opening but have had no luck. i was wondering if a 90mm NW throttle body will fit on an LS6 intake? thanks in advance.

Yep...you certainly aren't the only one to wonder this. It'd be nice to get around having to buy the FAST 90mm intake that you need to bolt the NW 90mm up, but as of right now, you really can't. TPIS modifies the LS6 intakes to fit a larger throttle body, but again, that's just more money.

78mm

The 90mm stuff also has a 4-bolt pattern, where the LS1/6 manifolds have a 3 bolt pattern.

Actually there is a solution to put a 90mm TB on an LS6 manifold:

your best option is a stock ported throttle body, unless you want to buy an aftermarket intake manifold
