    has anyone ported their throttle body?

    are there any expected gains with the usual bolt ons? or would a larger throttle body from corksport be better off?

    i remember reading someone did, you're not going to see major gains from it though, nor are you from the corksport one

    Better off getting the turbo manifol & downpipe ported and polished. You will def feel the increase of power at lower psi!

    but i wonder what kind of gains you would see if you did the whole system??

    i.e throttle body, intake manifold, head, 5 angle valve job, exhuast manifold or and after market equal length manifold.

    Well the whole idea but port & polishing exhuast manifold..turbo & such..is to increase the flow of exhuasts exiting the engine. This in turn will give you quicker spool as well as mor hp per psi!

    Don't forget..if you go to large w/ port & polish..you will kill your tq on the bottom end of the power band!

    I have the corksport one and it is a stock one ported and with a larger butterfly and you should notice improved throttle response and a little better top end.
