I just sold my Gs-T and bought a GS-X and lookin to upgrade the turbo. I am thinkin about big 16G setup from Extremepsi.

here is the link

What else do I need to do to get at least 300 WHP.

I already have apex'i N1 with the downpipe, walbro 255 fuel pump, precision 580cc fuel injectors(not installed) , MBC, boost gauge, air fuel gauge, BOV, and I also have FMIC but I didn't install it yet.

 

id say just get an safc and tune it and you should be good to go run around 20psi or so

 

can i tune it myself or do I need to take it to a mechanic

 

You can do it yourself if you can just figure it out.

 

What would be the max psi I can run with that setup?

 

i wouldnt suggest more than like 22 psi on those injectors. But im guessing all you have is the narrowband a/f ratio guage. That guage is pretty much useless. So you will also need a wideband guage like the aem uego. But yes its incedibly simple to tune the safc

 

Do I need to replace my cluth too?

 

Very soon my friend......It wont last long. Act2600 will be your next buy. And pm me if your interested in my afcneo and aem uego I have for sale. No miles on neo, and uego never even installed.
