Intake manifold port polish how much hp?

How Much hp will port polish give a celica?

[kaioshin]

very little most likely. Has anyone gotten this done yet?

Oh and fix your sig. It's CAI not CIA. :)

there is really not much to polish on the intake manifold. port matching the manifold with the intake port is still questionable until someone comes up with some dyno figures. The manifold piping is undersized and can be widened up to match the intake ports but doing so may effect air and fuel atomization and anti air reversion inherent from the mis-matched ports. I'm leaning towards some gains but not much.

I doubt you can gain much on a near stock motor.

It was DJ_GLITCH_OS I believe, he sent me a PM to a question I had, said he got 5-6hp. I guess you could also port the throttle body to match the manifold.
