Manifold for st185 externally gated

[GT4PWA]

Hey,

I ahve jsut had my new ECU tuned but it is having boost spiking issues. Long story short the guy who did the original plumping for the FMI and wastegate messed up and the wastegate only venting boost from 1 cylinder instead of four.

Is it possible to get an aftermarket manifold for a st185 3sgte that is externally gated or am i looking at having to get one made up. in both cases what sort of price you i be looking at.

Thanks

Technically being a twin entry turbo you need to run 2 waste gates or Y joint form both sides to run 1 wastegate (but that kills twin entry, unless Y branches are relatively long)..
