Project WRX

[flintster55]

Alrighty, I've been really lazy and not updating til now but we got everything finished up friday night. We started at around 4:30 and finished up around around 1:30. That includes an hour for dinner break and about an hour going to the machine shop and turning the flywheel. So total wrench time was around 7 hours or so.

The LGT trans had a bad case from where the throwout bearing tore it up. And according to the Subaru Tech I bought it from it had around 40k on it and was actually driven by a middle aged lady. But in short we swapped over the guts of the LGT trans into my 02 WRX trans. The LGT input shaft was a direct fit into my box so we just swapped that over. For the output shaft, we had to take it apart and swap the gear cluster over to my output shaft because my WRX has a 3.9 front diff as opposed to the 4.11 in the LGT. We also had to swap the 3/4 shift fork and rail from the LGT to match the spacing of the gears. We also used the center diff from the LGT because it had 40k on it versus my 107k. We also replaced the clutch, pressure plate, TOB, pilot bearing, rear main seal, input/output seals, and axles seals.

Onto the pictures- Sorry some are blurry andthe lighting wasn't exactly ideal.

Flywheel- Yay for hotspots from 5200 rpm launches :lol:

Fully assembled ready to seal back up


We somehow found places for those 50 loose screws and ended up with a finished product


All in all a great success. No real snags along the way either. The syncros of the LGT gears are amazing and require hardly any effort to shift even with my short shifter. I can go to first now at pretty much anything under 25 mph versus previously grinding unless I was completely stopped before. I also babied the clutch for about 200 miles but finally did some spirited driving last night and everything held well. 8)
