Hey everybody! I am new to the Audi scene, but I have been building fast BMW's for about 5 years now. I just recently bought a 2000 S4 and I love driving it. I also own a 1995 BMW 318i that i put a 94 540i motor into. I use this car to run my drivers schools at Watkins Glen. I am considering running some events with the S4 but I think that some RS4 intercoolers and new suspension might be a necessity. Let me know what you think. THank YoU!

 

Hey welcome to the forum. How about some K04 turbos and some new software too! At leat invest in some new ECU software.

 

My buddy has an S4 and he has had some problems with his software upgrades? If i do those should i prep the car to handle the power increase?

 

Yeah typically you'll need to upgrade the diverter valves and maybe replace the vacuum lines. Nothing extraordinary.

 

how much horsepower can these motors handle without internal work? What is a safe HP output for these vehicles?
