The 2.3l has the same transmission and shifter as a 1.9l The 2.8l shifter and transmission are different.
On the 1.9/2.3l adding the MZ3 lever has a couple of negatives.
First the factory shift lever is bent, the MZ3 lever is straight. The MZ3 lever will result in you shifting position moving up and to the right slightly.
Second the MZ3 lever is borderline too long for the 1.9/2.3l. There is a potential interference problem going into fifth gear if you push over to far. The selector rod can hit the driveshaft. This happened on my car and several others I know about. If you are lucky it may not occur on your car.
A better solution is Ron Stygar's shifter for the 1.9/2.3l. It is based off the 2.8l lever but is bent to duplicate the factory neutral position. Because the 2.8l lever isn't as long as the MZ3 lever below the pivot point there is no interference problem. To duplicate the throw reduction of the MZ3 lever with the 2.8l lever Ron can shorten the shifter from above to get the same ratio. With one of these shifters the throw reduction and force required to shift is identical to putting in the MZ3 lever but it doesn't have the downsides. This is what I have in my car now.
Ron's website has directions for building your own clutch stop and he also sells a very high quality one piece delrin stop as well. You can reach him at [email protected]
