    760 84 760 acc?

    Got the heater core and blower motor in, recharged the AC and that is happy now. But I have a question I haven't found an answer to yet. This is ACC not ECC Can you force it to Max AC I don't see how. I am not seeing the hot water valve close, it defaults open right?

    Aux shaft bearings

    Tore down a B230FT to diagnose a noise I presumed was a collapsed piston. Found the two inner aux shaft bearings showing copper? WTF? (have not measured pistons, but skirts appear normal and consistent) Noise sounds like a single loose piston.

    My Frankenstein 122 wagon project may be resuming. I am stalled, analysis paralysis.

    Boost limited to 250kpa B230 2valve Turbo cam Garrett 3071 3" exhaust in a 84 760 Auto I inherited this table, looking to improve it. I think it is very conservative and I am concerned about exhaust temps. I don't want to lean on it too hard as it gets hammered.

This time I got new "turbo" locking nuts and more new hardened studs (not butter bolts). I don't want the studs to come loose again and locktite has...

    Garrett 409080-5009

    What should I limit the boost to? It hits 200kpa really quick B230 in a '84 760 Auto. Nice intercooler, big exhaust, RC750's on pump gas. Not sure how much the trans will take. I'm not a boost junkie and its not my car, I don't want to turn loose a monster. This thing will easily make...

    760 84 760 Turbo vacuum stuff

    Shouldn't an 84 760 Turbo have a vacuum reservoir on the car side of the check valve that serves the climate control? It also appears someone has removed the (vacuum controlled) hot water valve, why would they do that? Im resurrecting a winter DD
