Terry, I preume you are in the US, so I can only guess based on a price
you would pay here, but I suspect you would be looking at around the $1K figure. Pat would be able to give you an exact figure if he reads this.
The main important thing with Turbos is, GOOD CLEAN OIL
. Use a good quality oil
and filter and keep it regularly changed. Turbos will not endure the life expectancy an engine will. So you would factor in two turbo rebuilds over the life time of the engine. But also note there, it is a REBUILD, not a new Turbo. A rebuild is new bearings and seals
. Simple and not tooo expensive to do.
The other issue is that Power comes at a cost. If you up the power from what the engine can deliver as normally asperated, the life expectancy comes down. So you will not get the overall life that the same engine could possibly give you if it was none turbo'd. (We are also assuming a perfect world here.)
Engine wear is a direct result of how many times them Pistons go up and down, so a High reving engine is not going to last as long as a slow reving one. (once again assuming a perfect world)
So to sum that up, if it was a slow reving commercial
engine, you could get the 10K+ hrs. But for a high reving turbo'd pleasure craft engine, I suspect you will be halfway through it's life by now.
