I have some knowledge in turbos, i was wondering if TO4E compressor,with a nothing out of the ordinary compressor/turbine trims, and a/r .70 on the turbine housing. i plotted some points on the compressor map, for the imprezaRS EJ25, which turned out pretty darn effecient, i just want some other opinions, i know this is a little broad, but knowledge is power!! thanks

 

Nickster, i do know that the T04E is used to very good effect (500HP) in Australia. TRP (rigoli racing) use them for there 500 hp conversions.
