I have 93 TSI AWD, the motor internals are completly stock along with the turbo, im wondering what kind of turbo it is and whats the max safe pressure to be running without just making heat? Im at 12 right now thats what it was when i got it. And does anyone know what the stock fuel pump capabilites are. I wanna know what to set my FPR to so i dont hit fuel cut. Thanks

Check the housing. It's probably a 14b if it's manual.
What is the big number on the cool side of the turbo, it should say TDO5H for example, which would be a 14b or a 16G. I'm going to ASSUME its a 14b. But the only way you can be sure is by looking at the compressor wheel, if it's staggered in height, it's a 16g. If all flush, it's a 14b.

You're gonna hit fuel cut at 15psi. You are going to need a new fuel pump to go higher than that and something to tune with.

Not fricking likely with a 14b and stock intercooler.... however 15 psi is a good safe limit for stock fuel system...
 
What can a 1g Talon TSi Turbo AWD stock bottom end hold up to for power? What does the stock 14b turbo max out at? (After you upgrade your fuel pump and injectors)
 
I checked it out and its the 14b, thanks. But ive been getting some back surge latley. Even using the stock bov it works great 1st and 2nd gear. so i replaced it with a greddy type S and in still getting a surge. Im affraid im going t mess up my turbo if it prolongs and suggestions. And ive already tryedmessing with the spring stiffness but im not sure what to set it at. Boost is set at 12psi right now.
