I recently sold my boosted '97 420A Talon. I had it for almost 9 months, boosted for 7 months with T3/T4 on stock internals @ 7psi daily.
Never smoked, leaked, knocked, anything..... I also put 8k miles with setup.
Took it to the track once a month and ran 14.91 w/sucky launch @ 96mph.

I changed the oil (Mobil-1 10W-30) every 2k miles. Tranny began to get rough in second gear, going in. I have an AWD TSi now, but I kinda' miss the 420A, lol. Really.
