Intake manifold upgrade question I have a 2000 Pontiac trans am with a BBK SSI intake manifold. I’m looking to get a new intake manifold because mine is cracked. The throttle body is only 85mm. I’m wondering what I’ll need to go to a 92mm or a 102mm. I know I’ll need a new throttle body. Will I have to get a new maf sensor? Will I have to get the car retuned? Can I use my BBK fuel rails with a new intake?

Fast intakes are nice but, the Dorman LS2 intake is a pretty nice comparble intake with a 90 mm neck and will fit a 90 mm TB. It supposedly uses the FAST bottom plastic welded to the Dorman upper. I had to smooth the runners before install but it was easy. I love the set up because it maintained my OEM fuel rail.
What cam do you currently run and are you willing to change it out?
Street car? Track car? Both?
For overall performance I did like FAST 92/92 setup with a big cam. Made plenty of torque chugging along at low rpm and pulled hard at higher rpm where the cam woke up.
