Anyone have experience with exhaust manifolds being ported ?

    Any gains from doing it? I'm not in the position to splashing out on a expensive no one with all the money I spending in the car lately :)

    There's always gains to be had with porting, efficiency is increased after all.

    It's usually done when you've either peaked performance or when your trying to get gains and you don't want to push the engine any further.

    Some folks have other reasons, but those 2 are the main ones.

    Aren't the standard manifolds good to quite a high bhp too? 450bhp+?

    They are good enough.

    In a nut shell; porting just improves the flow, which, in turn, allows for extra gains to be had.

    The more power you can extract from a stock engine, the better it will always be.

    In the old days, everyone would either consider it or just go for it as there were constraints, such as locked ECU's.

    Another mod was the Knife Edge Throttle Butterfly.

    These days, it's mostly the guys with NA engines like the civic crews that are doing it as they can't extract much more power otherwise, unless they go turbo or supercharged.

    Would you get more gains from a tubular manifold?
    Anyone tried the cheap ebay ones/japspeed or do they just crack

    Cheap ones just crack buddy.

    Hardly worth the hassle IMO.



    No worries buddy, it's what we're here for!
