Okay so I'm upgrading the turbo and all supporting Mods for My 04 Sti.I've been looking around and Finally found one that I like and in my price range.First off this is my Daily driver other than my Bike.But I'm looking for quick spool time and solid mid range power.I've never heared o this brand so am a little weary of the turbo.I've listed the Make and Model Below as well as all specs that I could Find...Any input would be awesome in helping me understand the Compressor and Exhaust trim in regards to spool time and power curve.I searched the threads but no success.....Thanx

EQ tuning has got a thread that is littered with dyno maps for all different types of turbos. I'd suggest getting a hold of GST and telling them what your goals are. Mike has got many tried and true combinations for varying power levels.
