Jm is correct,

The G96, and G86 type gearbox is now comepletely serviceable and is far less expensive than a rare vintage Tubo G50. These boxes were also popular to put into 4 spd Porsches or to update earlier cars with NA gearboxes that are producing more power. It's not like the Porsche race community does not want these and tosses them out. There is very good demand for quality G50 units in the Porsche race community and the kit/mid-engine market.

We have had extensive experience with the current G96 and G86 gearboxes and I have all replacements parts available and service these regularly. The G86.20 ( Boxster 6 spd.) seems to be a stout gearbox, and we make some internal machining modifications to help with dog teeth wear and synchro/slider wear. All gearboxes when raced require service and these are no exception. When properly setup and/or rebuilt they can hold a good amount of power. Once you get into the 500-600hp range, you may want to consider stepping up to something more race specific. However, the price for performance like JM has stated is very good when servicing these later model gearboxes. The parts are fairly inexpensive when compared to the earlier G50 turbo units.
