    depends on how high you're revvin'. on a turbo build keepin' the revs 'round the stock revlimit... you should be aiight.

    basicly what he said. Your head is not really affected by big hp #'s it is the revs that kill it. Try spining a GSR head to 10k+ you not going to be lasting long.


    Remember, by doing head work, you improve the HP more. Bigger cams, PnP for flow, valves and springs to support the higher revs and duration of the cam lobes. You just increased the redline, and the HP.

    keep your valves till they break. If you bend one, it isn't usually the end of the world. You should have a chance to fix it.

    Greddy 18G kit is a Pile. T3/T4 50 trim minimum is where ya wanna start doing a kit. Take that greddy kit, unbolt the turbo and manifold, insert into trash, and pickup a header like the SFP one, external gate and a nice garrett. You'll see a world of difference. Oh also at least do a hondata and throw that Greddy control box in the trash while you're at it.



    What do I know.. I'm a nobody ricer....
