Couple of things here, you shouldn't put the turbo in the feed to the matrix as it will totally mess up the coolant system and the way it works - Go and reads ruans thread about not bypassing the heater matrix as the same applies 
As for amount of boost and how long it will last with/without water cooling-
-the water cooling is only really the for when the car is switched off while red hot from ragging it (which unless your a retard you wouldn't do) and the oil provides sufficient cooling for the turbo bearings.
- I have been running 35+PSi for over a year with no filter and there is no more play in the turbo now than the small amount of slack in the bearings (taken up by the oil when the car is running) than there was a year ago.................they are a strong turbo!
Also removing the wastegate by welding it closed has no effect on EGT's, infact having a wastegate and too much fuel for the boost so that is smokes on boost is what causes crazy EGT's, with it de-wastegated if you add more fuel it ups the boost due to the extra exhaust gasses passing through the turbine so it still burns clean................................
I just thought I would clear a few things up
