I had an 01 GTi with the VR6 and it was a POS. The timing chain guides failed and allowed the chain to jump with 11k on the odo. Crashed the valves, and cracked all 6 pistons. It was still under warrenty but I got hasseled the whole time. I lost alot of interest in the newer ones after that. I'm way more into the Mk1s and Mk2s.
I still have an 84 GTi with a BSI Racing 8v in it thats all hopped-up. I'm not sure of the whp but it will beat my 83 GTi with a 16v swap. Definatly a great autocross chassis.
If anyone has interest the 84 is for sale, I need the room.
