Does anyone know if a BBK 70mm throttle body is a good investment. Another question is that i have a Diablo tuner, would I have to reset my parameters before i would install the throttle body.

 

First off, BBK stopped making the 70mm. If you order one, you're gonna get a 65mm. Second, if you install it, you're gonna have to port the intake for the new T/B. Cus if you don't, you will actually lose a little power. Third, unless you have some decent mods, the T/B will be a waste of money. Fourth, No. The computer will "learn" the new parameters by itself. It usually learns in the first 15 minutes of running time. That's what it says in the BBK install instructions.

 

thanks.. What kind of mods do you consider decent. The only thing i have is a K&N air filter, Which i am really considering getting the CAI. And I have an exhaust sytem that is it, and the computer programmer, I am looking for new plugs and wires also.

 

My mods are the bare minumum if you want to go with the T/B.

 

thanks for your help. Do you know by change what size the stock T/B is??

 

Either 56mm or 60 mm. I forgot.

 

60mm

94-98 are 56 from BBK

 

a nice set of adjustable 1.8 roller rockers will really smooth out the valvetrain and you will pick up about 5hp with them due to the 1.8's adding about .020" lift and reduced friction

 

I knew it was one or the other. Thank you!

 

60mm.....did you get my email?
