TPIS can modify a LS6 intake to accept one of their 90 MM oval TBs. But you cannot bolt up a regualr round 90 MM TB like a Nick Williams to a LS6 intake.. I would suggest a LS6 and have your TB ported a polished the LS6 intake will flow better than the LS2 intake ... if you use a LS2 intake you will have to change out your fuel rails too.

the LS6 intake manifold flows alittle better than the LS2, so you will be fine with a LS6. a 90 mm TB will only fit on the FAST 90mm intake manifolds and LS2 intake manifolds, and will not fit on the LS6 units.
for a bolt on car using a stock ported TB will be fine.

just so that you know, next time post intake manifold questions in the "External Engine" forum, you'll get more responses there.
