    Turbo upgrade

    Hi I have been trying to source an upgraded turbo for my a4 1.9tdi I was wanting a bv turbo but they seem thin on the ground and came accross a unit for the awx engine code with these specs GT1752 Spec Stage 2 (Uprated main bearings, 360deg large pad thrust bearing, balanced to higher tolerance, larger high flow compressor wheel +4.2mm,. Could some one confirm if this turbo would work. On my engine with supporting mods obviously.

    52mm compressor will work however i would have a larger turbine machined at the same time, the gt17 turbine is pretty maxed out as it is... Buy a gt2052v turbo then use the compressor, turbine and vnt ring within your own gt1749va housing...

    You surely know your stuff mate where as it's all over my head a bit. I was just going to buy it as it's advertised as a hybrid that will fit my engine how would it exspect to perform etc Adams's24 will it be worth purchasing ? I think it is advertised as an original turbo off awx engine with the modifications as above if that makes sense lol

    Hybrids are ok if done properly ! As i said the gt17 turbine is pretty maxed out and the 52mm compressor is good to push enough air however, modern turbos have extended tip technology and better inconell shafts and 6+6 blades so they surge less ! As i said, only upgrading the compressor works to some extent, i would upgrade the turbine to a stronger/larger gt20 turbine for good measure, however that will need a new VNT ring from the donor turbo...
