1ggte t3/t4 setup with factory manifold!

[Gttwinturbomk3]

Hi Gentlemen,

On my Supra because of funds at this stage i will be using the factory manifold on a custom t3/t4 setup with 38mm external wastegate.

Can anyone help me as to the fabrication method on where i will locate the wastegate and fit the flange above it. Maybe someone has done this sort of thing on there single conversion? It will consist of to steam pipes which i will fabricate to size. Fabricate the flanges plasma cut to size and weldup myself. The tricky bit is getting the best flow from the joining of the pipes to the turbo flange meanwhile allowing enough room for the wastegate to be fitted as well?.

Cheers.

I have further looked into this here, and have found that it will not be worth the hassle of bothering to do for roughly an extra 30-40hp at the wheels on 14 PSI with factory ecu. Better to get engine management and work your way up from there instead.
