Hi I have a f22a1 and bought a 70mm skunk2 alpha throttle body and found out it doesn't fit, does anyone know what intake manifold fits that throttle body and my f22a1 head

 

Best you can do is buy a throttle body spacer and taper bore everything to match your new throttle body. The stock opening on the intake manifold can only be bored out to ~63mm before busting through the aluminum. So 70 down to 63. Even after doing all that you're probably going to notice it's lazy when you jump on the throttle because you slowed the air velocity down so much.

 

Thanks, is there anything you can do to these motors to get more power. I put on a msd cap coil and rotor, aem fuel rail and regulator, Bosch 315cc injectors and maybe a little more

 

Engine swap, turbo or nitrous. The head flows decent on the F22A series but it's $$$$$ to get any real power out of them.

 

Ok thanks

 

None of the things that you have listed will make more power on your F22A1 engine. Even the big T/B will likely cost you HP in the mid-range.

I agree with Aradin... swap that big single-jingle out for a H22A or JDM H23A and let 'er rip tater chip. Otherwise, you will be spending big cash on a turbo kit.
