Why not get a USDM H22? There are plenty available, and they are cheaper, and have equal miles to the "JDM" ones. If you really want an LSD tranny: saving the money and buying yourself a Quaife would be a better buy, and perform better.

Please do NOT say the JDM has more hp, its like 9 hp to the crank, and maybe 4-5 to the wheels. You won't notice.
