Like most, I've always wanted more power from my 505 GTi. Previously I wanted to rebuild and turbo the original motor (ZDJL) or import/find a R21 turbo motor and mod/rebuild it but that still leaves me with the rather weak ba7/5, a ba10/5 with a Douvrin bellhousing seems to be made of unobtainium and boosted ZDJLs always seem to eat headgaskets. An engine/gearbox conversion seems to be the way to go, if not for nothing else because I'm sick to death of staying up to 2am most nights trying to find basic (let alone aftermarket) parts for all the obscure cars/engines I own.
So basically, how much power can the 505 sedan rear end take? Is the quaife LSD much of a strength improvement?
What have people done about the torque tube rear end?
