Gt30 Iw Dump Dimension Plz .

[discopotato03]

From people who have made bell mouthed dumps for the GT30 IW outlet what size tube is needed to form the outlet tube welded to the turbos flange plate ?

I did look at XR6T dumps but they are on the opposite side of the engine with the gates outlet under the main one rather than above it like it is low mounted on an RB .

Here is a link to Best Mufflers and a few pics of what they do for XR6Ts .

3 inch pipe, cut up the sides and hand work to suit the flange, then weld in little triangles to cover the hole.

Unless you want to run 4 inch?

Edit: Here is one of my first custom dumps (3.5 inch) I did for a GT35 on an Aristo, it may give you some ideas. My welding has improved in the last 4 years.
