Want to build costom turbo kit. Need advice from boosted guys!

How thick is that metal? I mean, yes, now cut a hole for the wastegate as well.... You can use a larger pipe that matches the size of the outlet. Probably 2.5" then you can use some smaller pipe for the wastegate and meet up with the downpipe 12" down the piping.

And Parmas is right, your actuator arm is too close. If your engine bucks a bit you might end up slamming that against the wall.

That metal is 1/4" thick steel. You cant see in the picture but there is a cutout inside the turbo housing for wastgate gases to reach that hole. In order to complete this downpipe a tight 180 degree pipe is needed at the turbo exit. Then a 90 is needed to direct gas tward the back. This would be a extremely difficult design for a divorced downpipe. It is also not nessesary for the low boost I will be running. If ever I install upgraded pistons and rods for more boost, I will need a new downpipe design. I am sure I will be able to reach my 160-180whp with this design. And I saved money. If you look at Focus Sh1ft's thread on the last page. You will see the zage downpipe is similar design to what I am making. There dyno test netted 180whp. At least thats what they claim on there U tube video. I have also milled some material away from the inside of the plate where the waste gate opens. This will insure it opens completely and does not make contact. Something I doubt zage did with there flange.

I have also pushed my firewall back to gain additional clearance between firewall and W/G actuator. There is still clearance between my firewall and heat/ac plenium if your wondering. I checked.
