They were (they don't make them anymore) one of the most reliable engines built - period. Why didn't they make more of them? - because they were not as profitable to build. And I would argue that the bean-counting mentallity plays a role, too. You see, the B234 turbo engines were really over designed and over built. Specifically, the pistons and other bottom-end pieces were capable of almost twice the stock horsepower and torque - there are quite a few fellows in Sweden who are running well over 400 hp with the stock pistons, crank, and rods. Without offending anyone, I think it's safe to say that there are philosophical differences concerning manufacture between different countries, say the US and Sweden or Switzerland, for that matter. The Swiss or Swedes would almost neglect the concern for profit if it means compromising the design or manufacture of something, whether it be clocks or car engines. The US manufacturers seem to run on a completely different mind-set: the number one priority is to the stock-holders! Anyway, B234's are not expensive to keep running. What usually requires maintenance/repair are ancillary items: ignition (DI), turbo controls (BPC's, BPV's, etc., the turbos are relatively robust items and, besides, there's really only one turbo manufacturer: Mitsubishi -Garrett licensee in Japan, but actually manufactured by Ishikawajima Hiremi Kaishi Jhuko), etc. The other little known fact is that even the 170 hp LPT has the same overbuilt/designed bottom end - even has the oil sprayers for the undersides of the piston!.....imagine the consternation this gave the bean counters in their concern for their stock-holders! But, there's two-sides to every story: GM is producing some pretty sophisticated engines these days, but I doubt one could say they're overbuilt, which can be said for the HO B234R. It also has one of the most brilliant engine management systems that is still light-years ahead of the ones used on 2004 vehicles - where others rely on more 'invasive' means to determine what's happening inside the cylinders, Saabs' use the spark plugs - ingenious!
