a good friend of mine was looking at caldinas a while back. we went to compression test three in the same day (2 were in the same workshop, another one was at a yard) and all of them had at least 2 spark plugs which were wet with oil when we pulled them out.
the odds are astronomically high that we could hit three in a row, on the same day and it not be a design fault. so my mate found a legnum in good condition and bought that.
the legnums run small turbos though, smaller than a T25 from memory?
