I'd have to concur with Griff. Blower motors are only good for 250 to 300 hours before a rebuild is necessary - at nromal boost: 5 - 6 lbs. Engines with boost exceeding 7 lbs will typically only last 200 hrs.

You can definately plan on spending another 10 grand rebuilding the engines. I'd say 5 grand, but mechanics ALWAYS find something wrong and if you're going to the trouble of pulling the engines and rebuilding them, there's no sense in skimping and not replacing pistons, etc when you do it.
