there are a few options. I get confused with the Mitsu tranny codes though...
the most robust would be from an AWD 90-94 Eclipse/Talon/Laser converted to FWD, but thats a little extra work. finding one from the FWD turbo version of the same cars will be almost as good. even from the non-turbo should be an upgrade.
also the early 4cyl Sonatas have a suitable gearbox than can be fitted.
there is a lot of mixing & matching of drivetrain parts for these Mitsu-based Hyundais. you can get a few different combinations from swapping bellhousings & flywheels, ending up with a larger, stronger clutch & a beefier trans.
I find that the HyundaiBishi info is quite thin here - I spend more of my time at
