Evan,
By my humble calculations, using the heads from the 1.9L on the 2.1L engine
should increase the compression ratio from 9.0:1 to 9.5:1. See my web site.

> Hello List!

> I am going to be rebuilding a 2.1 to put in my '85. I want to have even
more than a stock 2.1 when I am done, though. I have looked at some of the
other WBX engines that are on offer out there, and am wondering where the
the parts came from to make the increased displacement motors. You can
increase displacement by increasing the bore, or the stroke, or both. The
stock stroke on a 2.1 is longer than a 1.9, but the bore was unchanged. One
of the places I looked showed a larger bore (95.5mm vs. 94mm stock).
> I am not interested in sending out a crank for the work needed to increase
the stroke (not to mention finding different rods to match, etc., etc....)
so the bore increase is where I want to go.

> My question is where did these larger bore cylinders come from? I rebuild
my own engines, so tools and techniques are not the issue. Parts are!
