Default TBSS Intake Manifold ?

I'm thinking of buying a TBSS manifold for my 4.8L for my turbo setup. I heard that the intake is the same as the 4.8L intake other than the 90mm tb. Is it worth it to pursue or should I just get a bigger tb and be done with it ?

Depends on what other mods are accompanying I'd ask. And what are you aiming to gain? For the gain your $$ may be used else where with better results. You wont see huge gains unless your already nearly full bolt-on.

Do you intend on porting the TBSS intake? I certainly wouldn't. A lot of people have had great success with it and others... well a crappy port job lead to a thin intake and major supports inside the manifold were subsequently removed for increased flow.... too bad the dang thing looked like a set of lungs with every rev!

I'll be running a 76mm turbo/.96AR, stock bottom end with ARP rod bolts, Z06 cam/springs,241's, 72lb inj, Aeromotive A1000. My goal is somewhere between 550-650whp.

No plans to port !
