Yeah this is true, the quotes I've been getting for a td42 conversion are around $10k, whereas a rd28 engine is around $6600. I was just seeing what options there were. Would love a td42 but way out of my price range. Do you know where the best place to look for 2nd hand engines is? I've looked at a few places but I'm sure I could get a new engine in there cheaper than $6000.
