WhenI look for a turbo for an 159 1.9 16v (mjet) they are all listet as an GT1749MV not GTA ! How is that? Hmm, strange, my turbo could be an GT1749MV also. I've found the GTA listed in one of the Honeywell charts, but can't find it back. Here it's listed as a GT1749MV for the 159 1.9 JTDm

Differential is the weak point, consider Q2/Quaife upgrade for more torque.Thisturbo gives unbelievable effortless power when coupled with Gus's exhaust, re map and the FMIC upgrade. With it being a full 360 bearing the spool up is noticeably so much quicker than the standard journal bearing CHRA which is instantly evident in the throttle response. .
