Diesel crank in a 16v???

[calimus at techography.net (Calimus)]

Dan,

    Thanks for taking me to school on this.  Maybe there is a chance this
engine was rebuilt not too many miles ago and is just still tight.  I dunno.
I've checked the wiring pretty good, it's all larger then stock wiring and
all the connections seem nice and tight, not to mention free of any
corrosion.  I dunno, maybe the starter I put in is a bit flakey.  I'm sure
I'll figure it out.

    I do appreciate the info though, good to know that someone
didn't/couldn't just dump a diesel crank in it and make me continue to
scratch my head.  I'm sure whatever the issue is, I looked right at it and
didn't see it.  Back to square one it is.

William S

A 2.0L 16V has a very noticeable increase in mid range torque over a 1.8L.
If you had one of each there would never be any doubt which one you were
driving. So, it's probably not a 2.1L if it feels about the same as a 1.8L.
ETKA indicates the crank bearing shells are the same between gas and diesel
engines, so the crank will drop into the block. Course that doesn't mean the
connecting rod won't hit the side of the block!
Just to keep stirring the pot on this, you cannot simply swap longer stroke
cranks into an engine without also changing either the rods or pistons, and
it's almost always the piston. Aftermarket pistons are designed to a
specific CR that takes into account the difference in displacement. So,
basically, even if the engine had a diesel crank, the CR isn't necessarily
any higher than stock.
Sorry, I can't help on the starter motor issue.
