Thanks to Sam Walters, I have the documents of the "Lilley upgrades" from
Robert Lilley.
I like what he does in his writings with his 2.1L
Here's some questions for you engineering types:
1) I'd like to know if the 1.9L is a viable candidate for a high performance
motor.
2) Does the digijet limit the power, or is the Digijet the desirable FI
system
3) should I upgrade to 2.1L heads or get a 2.1L motor rebuilt w/
counterweighted crank, perf cam, ratio rockers,
4) how about stroking the 1.9L or the 2.1L motor.......offset crank grind
with oversized main rod journals?
5) upping the compression on the 1.9L?
6) who has done the ceramic coatings on pistons, sealing surfaces, exhaust
valves, combustion chamber...how do you
    like it, does it help keep the motor compartment and components
cooler?......any problems?
7) anyone using a #91 grind on their wasserboxer?.....better top end.....
8) 1.25 ratio rockers?....better bottom end?
9) ported heads anyone?
10) 3 angle valve job?
11) chromolly retainers?....I really like this idea.....along with the race
keepers
12) chromolly pushrods?

Since Robert didn't actually increase the displacement or the stroke, torque
should be the same...moment about the crank.
HP is estimated by Robert to be around 130....that's nice.....especially
when mated to that new SA 5-speed 4.57 w/ overdrive

I tried emailing Robert but his email address is no longer
working.......anyone know.....I have questions for the gurus

That's it.....I'm staying with the wasserboxer format on my next motor,
which is going to happen soon
I just want to fix all of the faults of the motor, like Mr. Lilley
