You getting a Promar engine? Not sure what they cost, but back in like 99 or 2000 I put a drop in diesel from Dealers diesels in my truck. It was probably the best money i'd spent. Cost me close to 5K, but it was completely rebuilt and dyno run before I got it. All it needed was fuel and a starter to run. It was complete top to bottom. Fuel system had been setup everything. at the time for like 2K more I could have had a turbo, but I was out of my league on the 5K engine let alone another 2K for a turbo system.
So longer story long if they will dyno run the engine before you get it I'd be all over that. If you build a turbo system for it how does that affect their warranty?
