my 94 AAZ Jetta is totally undergeared for its torque range and power.
I already have a tranny with .75 and would kill for the 400 rpms that a .68 would give.My engine cruises with power to spare at any speed.I usually drive around 125 kmph, and thats in the 3200 rpm range buzzin.68 would put me at 2750, major differenceand in summer i run 17's with 205/40ZR17's and it gives about 5 klicks over the speedo on speedand I still pull 800 k to a tank!
GTI's are great cars! I have been slowly converting my diesel Jetta to a GTD, basicallly a GTI with a diesel.Slow process.
what else do I need? I am going full polyeurethene bushings all around. a thicker front sway barno height difference but stiffer spring rates ( I hate lowered cars or jacked trucks) and aftermarket brakes and rotors, and 205ZR17 sticky yokohama's!My biggest beef is the amount of movementthe engine does even with brand new VW sourced engine mounts all around, on the front one, I even shimmed the bottom bolt to put preload on it. and still moves like a bugger!too much torque, need a spring/shock dogbone mount at the head to keep it tight!
oh movement is good, don't get me wrong. and you can't compare a GTI to a diesel.A billion times less harmonic vibrationsjust need a upper torque limiting armmy ol" 91 Lumina Z34 had one. had rubber bushings went right at the top.any twist the engine does is power wasted!I'll figure it out, already made my own load sensing timing advance off of the boost signal
