what size throttle body

nextime · 03-24-2002, 08:12 PM

i am planning to add the cobra computer package because i got a real good deal on it. the package includes... mass air meter, 24lb injectors and cobra computer. i am also adding a fuel pressure regulator. what is the best size throttle body for my engine set-up? i was thinking a 70mm throttle body.

Yeah, I would say a 70mm should do ya just fine.

Nice ride, by the way.

I always hear how the computer's in the cobra suck, and pull more timing, but im sure if your getting a good deal it would be a good gain all around, bigger injectors ect..

coupe5.0 is right, the cobra computer suck. what year is your car? looks to me like your looking to do a conversion to mass air, right??

i also heard to stay with my original computer, hey for $150 for the injectors, mass air and computer you cant go wrong. my car is a 1992 so i already have mass air.

yesir, that is a good deal for injectors, and if your getting the whole pakage, throw it on

btw, how do you like the steeda firewall adjuster? im thinking of getting one.

If you were going to buy a new one, buy a 70mm Holley.

the firewall adjuster works great except you still have to go underneath the car to see the play in the clutch cable for the centerforce clutch. but at least you dont have to mess with the 2 nuts on the end of the clutch cable everytime you need an adjustment all you have to do now is turn the adjuster on the firewall. i put some blue RTV on the threads on the firewall adjuster so it doesnt go out of adjustment due to vibrations. the new quadrant, cable and firewall adjuster are the way to go.
