Not me. GTI's are far too slow.
But.......I have posted it as it really would be a SENSATIONAL conversion. They are a great motor and its not hard (read as not overly expensive) to get 200hp outta them turbocharged. The Gti is a smaller motor than the GT Starlet but it does have its own issues.
I think the best option would be to get the G16b motor, which you can pick up for next to nicks, turbocharge it and that would be a force to be reckoned with.
When doing the Gti/Gt Starlet (or any other) you are able to 'rotate' the motor and g/box to get a compromise between driveshaft angle and getting the necessary clearances around the motor. I suspect that once you attach the tailshaft your ability to 'position/rotate' the motor in the engine bay will be diminished. Unless you are building a new exhaust tunnel the shaft has to be positioned somewhat centrally on the existing tunnel. In doing this (not building a new tunnel) you limit your ability to position the motor three ways:
side to side - tailshaft needs to be central (ish) on the tunnel
forward/backwards - gearbox/diff/prop shaft output needs to be in a position to go under the steering rack
rotationally - the gti is a VERY wide angled cylinder head so needs to be tilted backwards. g/box being attached to the motor being tilted means the diff will want to point at the ground. This is why i think the g16b should be used.
Actually, Honk, are you listening?
