Nigel Posted March 20, 2001 Share Posted March 20, 2001 When I get my T3/T4 built for my l28, I'm wondering if I should get a water cooled bearing. Is it worth while or not? Is there even enough room for the plumbing with the stock manifold? I checked the archives, but I can't find any discussion related to this topic. Any thoughts?

Evan Purple240zt Posted March 30, 2001 Share Posted March 30, 2001 BUMP??? huh? Anyways, nigel it can be done fairly easily. In theory the turbo should last longer. If i were to have another turbo built i would definiitely water cool the jacket. More piece of mind for me because i dont have one right now but would like one. BUT i also want a ball bearing turbo but i dont see that happening anytime soon! Too much money for me, cant afford it. evan Quote Link to comment Share on other sites More sharing options...

Guest Fast Frog Posted March 30, 2001 Share Posted March 30, 2001 Yes! It is worth it. I had premature bushing failure with the first turbo had I had in my pre-V8 turbo setup. I was running 17-18lbs of boost. I sent it to Turbonetics for repair and upgrade to a Super"H"; they installed a water cooled bearing. I never had any problems with the turbo after that and the oil temp was noticable cooler. Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted April 9, 2001 Share Posted April 9, 2001 I had to replace the turbo in the car that I bought w/118000 miles on it at 136000 miles (I change oil religiously every 2500 in all cars - or every 3 months - cheap insurance. Before the turbo always seemed to whine more than the new one - and the new one is vastly better both in spool up and amount of boost and outlet temperature. 10 lbs w/o intercooler for 40000 miles now. Turbonetics set me up w/T3-T4 watercooled, clipped turbine. If they'd had ball bearing I would have done that too, but this was in '94. I feel much better w/the water cooled center section, as to get home I have to drive through a neighborhood slow enough that I don't have to worry about coking when I pull into the drive -I only havet o shut it off. Because I don't have a compressor bypass, the ball bearing route would be great for durability, as well as spooling faster. Quote Link to comment Share on other sites More sharing options...
