Currently I have a 01 Tiptronic 103 k & an 02 Manual 130 k knock on wood no problems on either the 02 is a rocketship compared to the 01 got the 02 up to 151mph before I pulled back still had rpm&pedal room to go farther, I did headers exhaust and bypass tubes, short throw shifter eibach pro kit 19/11/295 on rear 19/10/165 on front olds upper strut tower bar, full maston bodykit with wing all around tinted lights lens'&glass all the way around even front windscreen I heard all the horror stories & shudder@times happy I have not experienced any major issues with any of my Porsches over the last 25 years, starting that religious maintenance is the key to a trouble free car? Just ordered oversize intake plenum & throttle body kit, wonder how Mick more performance I'll see?
