question about wastegates

[silvia_ca18det]

i got a gt28rs and i am thinking about getting a topmount manifold, but i was woundering if it is bad to change a internal wastgated turbo to an external by just welding the the valve shut on the exhaust houseing?

does this have any effect on performance if i change it to external?

thanks allot

What top mount are you using??? I don't know of any t2X top mounts out there??

As long as the welding is done properly it will be fine.

custom flange is being made and welded on! thanks for the quick reply! and yes it is going to be tig welded very nicely

Why not remove the flapper valve and weld a short pipe with a wastegate flange on it to the hole? It works well and allows the use on the stock manifold.

good thinking! that sounds like the most reasonable thing to do:)

thanks

Just remember to externally vent that gate !!

it can be done, like ppl say, but why? you either stick with the internal, or buy a new turbo that needs an external. no performance gains will be felt from changing the wastegate. if your just after venting the wastegate to atmosphere, you can do it with a custom elbow.
