they are modified t25s like the jwt sport 500 and Z1 stage ones. it just doesnt have a 360 thrust bearing like Z1, but it does used the updated CHRA. i chose it cause it seemed like the best bang for buck of of the 500 level. ill definatly post a dyno comparison to stock turbos one they are on. i just hope they dont do me wrong. on GMS site there is a dyno posted. showing 440 hp and 490TQ to the wheels. it doesnt tell supporting mods tho
