We have the WRX/STi Evo III 16G in stock. This turbo on a 2.0L EJ20 is just flat our killer! We have tuned several of them now to the high 200 wheel horsepower to low 300 horsepower levels with almost stock spool times.

The TDO5H 20G still spools almost as quickly but the compressor wheel is large enough that it just keeps pulling all the way to redline on a 2.0L EJ20 engine. The TDO5H 20G on an STi would be a killer auto-cross and road racing turbocharger that would spool very similarly to a VF-39, but keep moving air on the top end up to redline and past it if you build the motor and have the fuel mods to support it!!! Check the pictures below for some awesome shots of the turbo's from all directions!

The last picture shows off our modified up-pipes that we weld up to support Tial 38 or Tial 44mm external wastegates. This setup works awesome and produces rock solid boost control all the way to redline.
