Check out the part prices. I think you will find both have their good and bad points.

A lot of the D-Jet stuff has been subjected to work arounds for parts NLA. The big deal to look at would be the distributor and the trigger points.

But check out the price of a 280 warm up regulator. And if those valves were not adjusted on a regular basis it will eat up those cams.

It comes down to a case of there are a lot of 4.5 engines out there and not a lot of 2.8's.

But the rust thing.... That would be the deciding factor for me if either car would suit my needs.
