ZX's have gearbox issues, but they are really cheap to replace (~$1600 vs. $5500 for the Getrag in the Supra) and they are fun cars. ZX's have a high cost to mod, the first thing you have to do is fuel, so they're not inexpensive to bump the power. Good luck with the FD, I'm first to admit they are a great platform, I'd just be looking for a different powerplant...
