Stock Turbo

[Phoenix7]

if you have stock fuel system then you're better off leaving it alone...

Now if you get a boost controller I would not go past 10 psi if you keep the stock injectors. You'll also need a fuel cut defender since the higher boost will cause the fuel to cut out...

Now a lot of 13BT guys, especially the S4 peeps, tend to have problems with boost spikes...the wastegate can't handle the increased flow and you can blow your motor by boosting so high without the fuel to back it up. To help with the flow, a lot of people port the wastegate and that helps with over-boosting...

How's your car running? how long have you had it? mods? Mileage?

Got the car with A coolat seal blown due to the electric fan failing, I plan going back to the clutch fan setup, The car is makeing around 9 psi but cuts out around 9. someone has added an external regulator with gauge showing around 30 psi. It has stock injectors. I just got the car and finding alot of what appears to be little half done problems, it has 180k. Going to get the engine built and street ported. Mainly I want to boost at leat 10 psi if possible. Would I need to change the injectors and reset the fuel pressure if so what injector size and pressure would you say would be safe for 10 psi boost. It has a fuel cut defencer installed by the previous owner. Along with a 3 inch down pipe free flow exhaust system.
