Upgrade Gtr Manifold

[rhysc1986]

well i got told it was a shitfight to replace dump pipes without pulling turbos and manifolds out so thought may as well upgrade the manifold while i do it. not looking to spend anything rediculas as was not a planned thing to do in my budget. heard the R34 GTR manifold is good upgrade the the R32 GTR one?

no real point unless youve got bigger turbos in which case just get your stock ones port matched to the turbos

nothing much wrong with the stock R32 one. just grind out the exit port to the shape of the manifold to turbo gasket, if you've got stock turbos they'll also have the same restriction. You can pull the ex housing off the turbo and port it the same way to match the same gasket, this should improve response as the standard design has a bit of restriction. Some photos to demonstrate- you'll see the black section that doesn't match the gasket, this is what you grind out. (And there's some ported manifolds).

You have a stock motor - no point unless you are 400rwkw+, and you won't be doing that on a stock motor!
