I’ve always liked the Audi TT, ever since Need For Speed Underground 2. It has been a joy working with this Nardo Grey Audi TT MK3 8S featuring the robust 2.0L EA888.3 engine. We rebuilt the engine with slightly lowered compression aftermarket forged pistons and replaced the factory IS20 turbocharger with CTS Turbo BOSS kit, which is actually a customised made-to-fit Garrett GTX2867R.
Big turbo setups like these will require additional cooling. Hence a WagnerTuning Competition intercooler is put in place to allow more charged air volume and reducing the overall charged air temperature. On top of that, KATECOOL engine oil cooler is also used to reduce the overall oil temperature.
Results shown on the dyno is 428 wheel hp and close to 500Nm. That’s 200 wheel horse power more compared to stock!
