Zamani, it's a 166 engine with 164 24V M L 1.7 electronics.
The 155 with the 24V and 156 gearbox is a great combination, the car really goes, at this point i prefer taking the 155 to the track because it is faster than the 75 with the same engine even after i installed a TS box.
that is one great 75/Milano Lenz, with the new brakes did you change master cylinder too? I'm curious if you used that 25.4mm BMW one and your results.
Thanks Matt
Matt i used the 25.4 mm ate bmw master and it works great with my set up, with the oem master i hardly had any pedal, but with the 25mm the feel of the pedal is so much better than it has ever been before. Almost as good as on a modern alfa romeo. However the ate needs a rebuild, because it has probably been lying aroudn to long.
