1988 - 745T: It is a Mitsu unit but I do not recall model number, can any offer info?
unit has atleast 150K on it. Is that normal? The manifold gasket to turbo (4 studs?) unit is blown and repair is coming up, tap, tap, tap.


What is turbo life expectancy? , I'd like to find/buy a reasonable $$ unit before I really, really have to.

I would think that a turbo with 150k on it would need replacing. I can't offer info on the turbo it'self or upgrades, try www.turbobricks.com forums. That's where a lot of the RWD guys hang out.
