The day I brought it home. Lowered on coils, Rotiform BLQ 18×9.5.
52687

First on the list of mods was this eurosport FMIC and piping.

Next came the TIP, CAI and motor/trans/dogbone mounts.

The car was approaching 200,000 miles so I decided to do a rebuild on the 1.8t with some goodies. Forged IE rods, Autotech intake cam, power pulleys, gates timing belt, manual tensioner, sai/evap delete, closed system catch can, silicone boost hoses and a big port intake mani off an AGU 1.8t with adapter plate.

The intake mani got sent in for powdercoating while the engine was removed and rebuilt.

Everything was hot tanked and new. ARP hardware, calico bearings. The old bearings were in such good shape it was almost a waste to replace them. 200k miles and literally no sign of wear. Plastigauge said they were in tolerance but they were replaced anyway. I believe this is good testament to being very well maintained. The head was refreshed and the cam was installed with OE springs and valves.
52695

The motor was now ready to make some horsepower. I began acquiring parts for a K04-023 turbo (audi tt 225 fitment). Its a daily driver and I was looking for 300hp-ish. After talking to doug at Frankenturbo I ordered his f23 kit. I was able to find a NEW TT exhaust mani and I sourced the other parts needed to make it work. Let me tell you...it was a chore.

Exhaust is a 3in system from 42DD with a K04 fitment downpipe. I'm also installing this HUGE 6in filter with a 6x3 velocity stack

Busch Light can for scale. It barely fits. I did a test fit after purchasing to make sure.

Anyway, I begin the install on 11-30-20. I'm super excited and will keep everyone updated on the results! Thanks for looking! Here is a more current pic of the car

Turbo parts installed 12-23-20. Still going through the Tuning process with Motoza. There is a fueling issue at high rpms that still has to be sorted out. Updated pic of the engine bay after install.
