what size tb to run

[92 lx]

I've got 93 cobra intakes and i was wondering what was the biggest size throttle body to run with out hogging the intake out. Help please.

70mm or 75mm! What about your MAF?

70mm ftw

You have to modify the 93 cobra intake to accept any t/b bigger than a 65mm.

It doesn't take much though.

Wanna borrow my 105mm Accufab Race TB? :burnout:


Seriously, Lee is right. Doesn't take much with a die grinder. And if you don't have a die grinder, this is a perfect reason to go buy one!!

Here is a pic from when I opened up a Vic 5.0 to accept a 90mm...

You can see (hopefully) that I just put ~1" transition there.

Yep. ChipR4cam on here had to remove maybe an 1/8" for my 75mm t/b to fully open and not hit any part of the intake

I have a cobra intake and a 70mm TB. I did not have to modify anyting. The opening in the 93 Cobra is 70mm. Maybe I was lucky but the gasket and TB lined up without have to modify anything.

Interesting. Do you have an OEM cobra intake or one of the newer aftermarket FRPP intakes
