• I had a FF built with a .71 5th gear built for my jetta (had the dreaded AWY) and it still is not tall enough for comfortable interstate travel.
  
  I think you should definitely start with a 3.67 RP.
  
  I have thought about having another tranny built up to go taller.
  
  Don't forget how much you can do with tire size.
  
  I am going to try 195/70/14's (currently running the stock 185/60/14's) before building another transmission.    This should put me at 2625rpm for 70mph.
  
  Good luck!

• Anyone know why they only built the ACH for one year, and only in the 1985 1.6 NA?

• what are you building that weighs 1200lbs total???
  
  I built something to that tune, but it'd definately not safe over 110kph :lol:

  I would go with the 3.67. I have an ASF in my Jetta and it moves about just great. ...

  
  
  I love my ASF and equivalent trannies in my 'diesel road cars' (gleaned from gas jettas)
  
  I also liked a 9A with a .71 5th for a mountain car with a tall 5th, and 3 gears very close 30mph-50mph
  
  but.... my best economy has come for running my 1.6's flat out with .75 5th's  :?  or with low ratio 4spds (again, screaming at road speed)
