nah, the vr6 is a 02A 'box (but with different ratios to a gti one), and the 18T has an 02M...it can be fitted but is lots of work, and not really worth it. so stick to the vr6 one. may be worth seeing if yours is repairable though. there are some good upgrades available for the vr6 02A 'box, such as a 6 speed conversion, and a quaife ATB diff. you can also fiddle with the final drive ratio to alter the ratios.
