10th AE here
 

with upgrading my fuel system, i was thinking about upgrading my turbo. Are there any suggestions. And i wanted to replace my stock air box. any suggestions. I have up grades but i dont know what to do next. my boost is aroudn 10 because of ym exhaust and i have an fcd. can anyone help me out?

If I were you I wouldnt replace your airbox or anything from the airbox to the turbo untill you get some better control through wastegates and and tuning. MAYBE I'd buy a drop in K&N filter but not much else. If you do this first, you will severely overboost and blow her up.

Also, if you are running 10psi on stock fuel setup you are already over the limit!


I'm going to order what you should do loooong before modding the intake.

~250 rwhp

1. Walbro fuel pump ($130)
2. Apexi SAFC ($200)
3. 720cc secondaries ($250)
4. S5 turbo manifold/housing with upgraded compressor (~$250) at 10psi
5. Ported wastegate (Free)
6. Custom intake ($100)

After that, you can think about these;

~300 rwhp
Efficient S5 turbo with upgraded compressor max efficiency at about 13psi
1000cc secondary injectors
Intercooler
