It sounds like you have a typical B202 turbo engine. My advice is that if it isn't burning oil don't mess with it. The OEM tri-metal bearings are almost guaranteed to be fine (regardless of mileage). The only possible finding might be some congestion of the piston rings which will usually show as burning oil or low compression. Of course a worn turbo can burn oil too so take that into account. If your compression is good, there's no tailpipe smoke and it screams with hard throttle then the only thing worth considering is replacing some seals and gaskets. They are all much easier to do when the engine is out of course. Watch out for cheap oil pump o'rings, the cross sectional diameter is critical and maybe replace your old oil cooler hoses. Buy bulk oil cooler hose, salvage the end fittings and use double fuel line clamps at each end and you'll save a lot of money there. The B202 is nearly bulletproof and will run like new as long as it gets good oil and regular oil changes. I work with machinists a lot and build engines now and then and I can tell you that if you talk to a machinist or take your engine to one there is no way he's ever gonna agree with anything in this thread. He'll say that you need: Pistons, rings, bearings, valves and all the appurtenant machine work at about $2000-3000 total. The only new pistons now available for these engines (that I can find) are made to order forged pistons at about $700+ a set and every time I've torn one of these (good running) engines down the factory pistons, bearings, crank, etc. are sweet. Put your money in a transmission rebuild and some engine gaskets and seals, maybe a clutch.
