Stock Eurovan 2.5 compression?

[Bruce Bell]

Yes, those 88-90 motors as well as the tectonics 94.5 mm crank applications
used the 144 mm rods. Caution here, there are, as I recall, two different
wrist pin sizes for the 144 mm rods. 20/22 mm? Some early 4 cars, both 4 and
5 cyl used 136 mm rods. Those would be too short to consider.

I seem to recall the EV crank was machined to use rifle drilled rods.

Yes, there is a short deck 2.0L.  I believe the only USA application for
this
engine was 88-90 Audi 4cyl. cars.  These engines are desirable to the VW A1
hotrodders because they fit into an A1 chassis w/ no modification to exhaust
pipe or cutting the raintray.  I don't know how the long stroke is packed
into the short block, but it does fit, and they are considered to be
reliable.

So the I-5 engines just skipped over the 92.8 stroke length?
