I know with all the upgrades i'm in the process of doing i'm gonna need to get a larger TB sooner or later, preferably sooner. Will 75mm be suitable with the mods.

GT40p heads
Trick flow cam ? ( maybe trickflow stage 1, but not too sure, but a cam for sure )
24# injectors
Large MAF
CAI
Adjustable fuel pressure reg.
Advanced timing ( 14* probably )
And an intake from an explorer or cobra if i can find one cheap
BBK headers
4.11 gears

you dont need anything bigger than a 70mm but if the price is right buy the 75

I'll look to see what i can find in 70mm.
Is "the bigger the better" when it comes to MAF ?

Tims 88GT

no not really, the mods you have i would say stick with a 76mm. Bigger is better is not true in most cases.

yeah 70mm at the largest, 70 works well w/ a cobra intake

id say: 65mm for sllight mods, 70mm for built motor, 75mm for pure racing apps.

^^ yep. 75mm MAF, 70mm TB max unless your car is blown and even then you still may not need bigger than 70.
