ummmm..... i thought a 2L 16v's compression ratio is 10.0:1?
and the bently does seem to agree with me here.

Still, the 1.8 G60 originally has CR something like 8.5. But having a 2.0
with the same CR would require more fuel at the given intake pressure
since 2.0 pumps more air through, and keeping the same chip will cause
lean mixture. Ok, it will try to compensate by Lambda signal, but will
it?
With driveability I was thinking the low rpm, easy city driving. This is
importand since driving the G60 I find myself going to police department
more often. Why? If you go easy on G60 car, it feels too soft and weak,
i think of 8.5 CR with negative intake pressure (if we are going slow),
and to make it little quicker and responsive, you have to keep more RPM
what eventually leads to running faster, then G60 feels alot alot better
than
going slow. This all is subjective, but it is so. I want a car, which has
response even when I drive easy. I was thinking that tranny with 3.9
final
could cure this.
I forget what a 2.0 16v's stock C/R is but if its 9.5:1 or less id stick
with
it, much more drivability for sure, thats what turbo miata 1.6s make more
power boost for boost and have better street response than mildly built 323
GTXs with the same basic block in them...a few of the GTX guys are planning
on going to 9:1 with miata pistons...if your engine can withstand the
horsepower level it yields you can run almost any boost level on any
compression ratio, its just a matter of having enough fuel and changing the
timing enough...hell they have a supercharger and turbo for the honda
S2000,
i think its stock CR is like 10:1, personally id say for maximum
performance
with great drivability and simplicity ditch the stock ecu idea and use
whatever big injectors you can make fit <something from the Porsche family
id
imagine would make a good donor> and use a programable aftermarket setup,
once its dyno tuned professionally you'll have a very fast excellent
running
car
