Thought I'd chip in here as I have an 08 OBXT 5MT and was originally looking for reliable power.
I have the following:
Grimmspeed TMIC (I could not trust the OEM one with nearly 20 PSI)
Cobb catted down-pipe
IAG Air / Oil Separator (Worth it in my opinion. The OEM PCV system just doesn't cut it)
Cobb Access Port (Pro tune for E85 and 93)
Southbend Stage 2 Endurance Clutch
Chose not to do anything to the cat-back or intake as stock was fine for what I wanted.
I also have a BCP x400 turbo, but I still consider my car to be "stage 2" and it puts down 320 whp on E85.
However, I would recommend replacing the OEM oil feed hard line for the turbo with something more reliable. I just wetn through replacing it myself. The IAG kit can work but it's a tight fit on some years. I ended up using part of it another some other parts, but definitely get rid of the filter in the banjo bolt asap.
I bought ine at 88k and ended up having to to rebuild at 100k, but besides that, assuming your turbo and engine are in better shape that mine was bought when I bought my car you should be good.
