To convert a 1988 MR2 20Valve 5-speed into a 6-speed, you would typically need a 6-speed transmission from a compatible model, such as the later Toyota MR2 Spyder (MRS) or a 6-speed from the Toyota Celica GT-S. The conversion also requires modifications to the transmission mounts, shift linkage, and possibly the driveshaft. Additionally, you may need to address the ECU and wiring to ensure proper functionality of the new transmission.
