Used s5 turbo with a huge ported wastegate will solve your problem. I run stock 5.5 PSI w/ the smaller 2.5" full RB exhaust.
You can combine your good s4 turbo with a blown s5 turbo. All you need are the manifold and hotside.

hey man you should really take your turbo off and port the wastegate hole and weld a new flapper door on to help control any kind of boost spike. a good psi is probly stock which i think is like 6-8psi. i hear the stock turbos arent that good at higher boost levels so you will wanna stick with that probly. i just got done with porting my wastegate hole and i love that i can finally just ****** rip it up and down the canyon with no fear of over boosting. there is a website fc3spro.com that has a step by step. check it out.

there is A LOT of material that can be removed, and just opening up the holes under the flapper isnt enough!

BlueTII ported my wastegate. Maybe he will chime in and post a pic or two. His stock turbo is awesome.
