i got a airsearch t3 turbo with a internal wastegate thats all F-ed up..i took it all apart and was wondering if i can weld a parts on the turbo where the external wastegate use to be and use it as a normal turbo and go with a external wastegate..is this possible

 

we tried welding the flap shut ofa t25 but it kept cracking on the welds. we ended up just putting a stop screw on the down pipe flange to push the flap shut. it works well

 

Totally doable. Just weld the door shut really well, and then use an external gate.

 

cool thanks guys

 

Or do it a better way for cheap - buy a 5-bolt flange & gasket that doesn't have the cutout for the wastegate hole, put it between the wastegate and turbine housing (maybe get longer bolts too) - finsished. You can now reuse your DP w/o welding too, although its a moot point if you're getting a different manifold.

One problem with that is if the flange comes loose or leaks any, you have no boost.

Its annoying...
