this might be a dumb question to some of you but I want to buy a ported LS6 intake manifold. Now with that, what TB's will bolt to it? could I buy a FAST 92mm and it work? what size is the stock TB? also will I need a new MAF?

FAST tb's are 4 bolt ls6 intake needs a 3 bolt. You can buy a FAST but it wont work, you need a stocker.

you can get a ported stock TB 78mm TB for $50.the stock MAF will work fine.

okay then the hell with FAST. ws6store said their BBK 85mm works fine with ls6 mani's

and thanks to last poster, so stock size is??

stock is 78mm. I'm very happy with my ported TB, goes nicely with my LS6 intake for the whole budget swap scenario.

Whats the price difference from ported vs stock? Never really seen any concrete results from having an LS6 intake ported.
