This is our latest B5 1.8T build that we completed this year, and it is definitely the most fun.
This particular customer came to us with 1997 A4 1.8T that hadn’t run or been registered since 2001. The car had a chewed up disaster for a wiring harness, a cobbled together turbo kit with both internal and external wastegates, and had been through a few motors. In fact, he hadn’t even seen the car in 6 years when he shipped it down to us.
He wanted a reliable, consistent, quick-spooling 350+ HP setup, without sinking too much money into the motor.
Once we got started on the car, more and more of the old hardware had to get tossed out in favor of new, professionally engineered performance parts. It’s always easier to start with a clean slate, to say the least.
After countless hours of replacing hackjob parts and removing rat nests, dead squirrels, and spiderwebs, the car was ready to hit the dyno for break-in and tuning. We even had it detailed when we were done. Here are some pictures, specs, and dynos from the completed project.
