I’ve had two hybrids on my 2.3fpt. The first was based on a GT30 and definitely gave better response than the standard unit. However even with a 360 degree bearing the seals gave up after a couple of years of hard driving and at that point I moved to a T3/T28 hybrid with roller bearings, comfortably rated for 350hp.

I'm in the process of trying to get a ball bearing hybrid for my 2.3 Carlsson. One specialist says I need a GT 28 Series good for 320-360hp another says I need a T25-T28 with a .64 exh housing and a .42 or .6 or go to a 0.8 T250 compressor housing, another says I need a T28 with a .64 housing as fitted to 4x4 Cosworths.
To say I'm confused is an understatement. I want a ball bearing turbo which is a straight swap if possible which spools up fast and can give me 2 bar without running out of steam. I'm running 1.6 at the moment but life expectancy of the standard unit is low....probably measured in minutes!
Anyone offer any advise on what turbo I need to fit and who can supply it. As I've been quoted between £795 to £980 +vat I want to make sure I am buying the right turbo for the job.
