hey just wondering if i can use my aftermarket header as a turbo header - i know everyone used hf manifolds with an adapterplate but wondering if i could just use my header , it will be equal length but not sure if it will spool properly or not - also how hard is it to make a bseries manifold fit a dseries - also does it matter which way the turbo is mounted on the manifold - thanks
