Weight was kept lower, underhood temps near the brake reservoir were lower, downpipe flow was MUCH more linear, and I got fantastic spool. Made 15psi @ around 3500rpm with a .63 a/r exhaust housing.

Here are some pics.

Hi I have crappy T25 bottom mount and i want to modified it to be a T3/T04E manifold like you, and i was wondering if you buy the t3 flange and then You welded? or just cut the t25 flange and make a new one?

And mY last question its how yo do to put the external wastegate? and why the wastegate its in the top?

You can order the t3 flange off the internet, I know there are a few on ebay. After that just cut the t2 flange off and weld the t3 flange in it's place.

As far as the external wastegate goes, you basically put it wherever you have room. You will probably have to end up making a wastegate "runner" so you can get the actual wastegate away from the crowded manifold area.

It will depend on the turbo and the exhaust housing of the turbo. It's possible that a downpipe for the SR20DET would work if the turbo has the correct output flange. There is a mid pipe that connects the turbo to the downpipe usually.

Something like this...Mid Pipe

Connects to this...Down Pipe
