What does it take to hook up a six speed to a 92 3000gt vr4 that had a five speed?

To hook up a six-speed transmission to a 1992 Mitsubishi 3000GT VR4 that originally had a five-speed, you'll need to ensure compatibility with the engine and drivetrain. This typically involves sourcing the six-speed transmission, along with the necessary shift linkage, transmission mounts, and possibly the ECU for proper tuning. Additionally, you may need to modify or replace the driveshaft and axles to accommodate the new transmission. It's also important to consider any necessary wiring adjustments and the potential need for custom fabrication.
