as for it opening honestly half an inch or and inch less space makes no difference to me... again im just curious if it can be done.
Its one of those things that can be done if you have the money. Whether or not its realistic to try is a different story. You'll have to remove the entire motor assembly out, and try to retrofit one from a GP, assuming that the window dimensions match or come close. Then there'* the mounting points that you'd have to fabricate, and there'* no guarantee that it would fit properly. Then there are sealing issues and adjustment, and it would take you a very long time. These are just things I could think of off the top of my head.
A lot of things will affect airflow from the sunroof, including the position of the passengers, the volume of the cabin, the location of the windows and how far down they are, and many other things. I highly doubt the higher flow was attributed to the window style, as when moving, air would otherwise just fly over the raised sunroof.
As for additional modifications, if you want something worthwhile to work on, get polyurethane control arm bushings for the front. if you already have them, you'll notice that they don't work properly, as mine don't either. The reason is that from the factory, the factory bushing had a notch that went into a dent in the subframe. There'* no dent here, which allows for too much play instead of having the bushing rest on a flat surface. The solution is an aluminum plate under the bushing so that the bushing rests on a flat surface. I'm going to fabricate some of these for myself soon, and I can make you a set too if you're interested.
Otherwise, go to the rear and try to find a way to make a rear strut tower bar. These are things that will make an immense difference for our cars.
