Re: 2 barrel to 4 barrel

huh, the "bad word" filter never got you. Sneaky.

Yea, the "2 bbl" is TBI, it's not a 2 barrel. It just so happens to have two bores. not to be confused with a crappy old '70s 2 barrel carb.

It's a decent system to put fuel in the car though. If you want the car faster (that is the root of most questions on this board eh?) you want to tackle other things besides your TBI system.

Heads, exhaust, cam, etc.
