Audi TT Stage 3 IS38 Swap

This Audi TT Quattro originally packed the EA888 with the IS20 Turbo,
The Audi TTS however has the same engine with the IS38 Turbo.

This vehicle had the IS20 Turbo changed for an IS38 aswell as other essential supporting modifications such as Downpipe, Intercooler, Intake

After Stage 3 Tuning of both the Engine & DSG Gearbox we now have an extremely fun pocket rocket of a car. 

The performance of this base TT is now in-line with a Stage 2 TTS making it a bit of a sleeper ;)
