I am looking at picking up a 740 turbo (intercooled) Just wondering if anyone has some recomendations on model years to stay away from and what to look problem areas to look at while inspecting.
The 740/760 Turbo used non-watercooled turbos up through the '86MY, so I would stay away from those unless the turbo has been replaced with a watercooled one. The '84 760 Turbo has the strongest engine with a forged crank and rods. The '85-'88/'89 is the weakest, with small connecting rods and a cast crank. By late '89 the B230FT had improved crank bearings and larger connecting rods, which makes this one desirable. From '90-'95, the B230FT used a smaller turbo (Garrett T25 or Mitsubishi td04-??) than in previous years, and the exhaust manifold was improved. These cars build boost at much lower rpm and accelerate quicker, but the top end power is not as good as with the older Garrett T3 turbos.
The last year for manual transmission in the 740 Turbo was '91, and the last year of production was '92.
Check the intercooler hoses to make sure they aren't soggy and soaked through with oil. Make sure the turbo builds boost and doesn't smoke.

Thanks for the info guys. I'm taking it out for a test flight tonight and will let ya know. FYI it's black with full tint....looks good but I haven't been under it yet
Yeah they are, but the wagon looks best on both ends. The rear of the sedan looks funny with the huge trunk release, straight rear window with no defroster lines on it, it just looks goofy to me.
took me a while to post but it was a piece of crap...turbo gone lotsa oil...front end looked like it had some damage!!...the search continues
