"Ported" or "Polished" Stock Inlet Man.

[Freebaggin]

Has anyone cleaned up (or match ported) their stock inlet manifold on their RB25DET? Is there anything to clean up? Any power gains if you did?

Don't want to know about Greddy plenums etc. More thinking of cleaning up factory plenum and maybe bigger throttle.

I have had my plenum cleaned out, & i have an oversized, not stock, throttle body...

Not that much of a noticeable difference, just piece of mind that everythings clean & flowing smoothly...

OK, thanks for the feedback.
