    GH Sigma, RWD 4g63 Manifolds.

    Pretty much decided i'll be getting that top exhaust manifold. We'll be chopping it up anyways. So plenty of opportunity to strengthen it and put some bracing between the head flange and the turbo flange. As well as a JMF intake. Now trying to decide between the Garrett GT3582r and the...

    Yeah i'm leaning towards the JMF as well. As for exhaust manifolds, we are going to be bracing it a fair bit. When it breaks, i'll copy it with a stronger metal. Only prob with steampipe is you can't get the desired radiuses that you can with SS..

He thinks this thick ass pan will be a good idea and it'll be interesting to see if it holds up under...

    4g63 Sigma progress
