Honda CRX Mugen LSD - Maximum Traction

With the transmission in its current disassembled state, inspect and remove any fragments from the housing magnet found directly adjacent to the differential assembly. The Hasport transmission had plenty of shards littering the magnet thanks to the numerous track events it encounters.

Inspect the inside of each synchro ring for wear. Also, inspect the synchro teeth colored gold in this image for uncharacteristic wear. The teeth should be sharp and pointed. If they look rounded or worn for any reason it's a good chance that your car has a tendency to grind or not engage smoothly when shifting through the gears. Replace the oil seal and countershaft bearing if necessary.

Brian found a serious problem with the factory housing when inspecting it for any problems. The K-powered CRX distorted one of the dowel pins used to keep the two transmission pieces aligned. Rather than pound the hole back into a perfectly round shape, which was nearly impossible, Brian took a grinder and file to rid it of excess aluminum surrounding the dowel and ensure the housings fit snug when reassembling.

Brian took the final drive pinion off the original JDM Integra (RSX) Type R differential, which sports a shorter ratio of 4.764 compared to a longer ratio of 4.389 found in the '02 to '04 RSX Type S transmissions.

With the Mugen LSD in place and magnet repositioned, the tricky part of installing the countershafts takes place.
