I own two Audi b5's. 1998 and 1997. The 97 had a big turbo build but the car was junk. Swapped over to my much nicer 98. Everything required was swapped over. The turbo is a garret gt28Rs. I swapped the Ecu over as well. 440cc Injectors too. The donor 97 ran despite the rod knock and the rest of the junk. But I had to give it gas to keep it running. Felt like it was having fuel cuts or something of that nature. Now that donor car sat for years before I bought it for parts. And it ran good before it sat. Now once everything from the donor car is swapped over, the new one runs the same. I just assumed dirty injectors? I only started it once for the first time today. Any help is much appreciated. Prefer if someone could get ahold of me via phone? Thanks!
