The turbo on the 140 & 150 is the garrett GT2249.

Its a fair size turbo, BMW used it on their early 3.0diesels.

Mine uses this turbo and I run it at 1.9-2.5bar (30-37psi)

When mine goes I may look at a slightly larger turbo, but you need to be very carefull on the intake side, do not go too big.

Apparently the turbo off the 316/416cdi merc sprinter van, (I think its a GT2249) is some sort of upgrade, supposed to have a bigger intake pipe for better flow.

You can hybrid the standard turbo.

I take it to get 200bhp you've done the FMIC and intake mods as its near impossible to get a proven 200bhp without these mods.
The best way to get increase the boost (as the ecu runs an overboost function) is both by chipping and a voltage clamp on the MAP sensor.

there is a thread on FMIC tips in this tuning lounge which may be of some help in tuning, nothing on turbo's mind.
