[Question for all those with a 16v 2.0 block and 16v 1.8 head]

[Rabbit16v@attbi.com (Rabbit16v)]

It's the same as a stock 2.0L 16v.  The combustion chambers in the head are
the same betweent he 1.8 and 2.0.  Actually, the 2.0L heads re better than
the 1.8L heads (flow better stock, more material to port with).  Plus, as
far as pump gas is concerned, the regular octane (which is 87 here in the
US) is better for the 16v and the knock sensor system than the higher pump
octane (92).  Someone did a dyno with each on the same car and came out with
better numbers with the lower octane fuel.  Anyone remember who that was???
Now if you racing, the 110 or 112 at the track will be better just from a
pure octane point of view (it's been my experience anyway).  HTH!

What does the compression ratio come out to be.  I have been searching on
the
tex and haven't been able to find good answers.  Thanks

Ah the great mystery of life. I've had one for two years and have yet to see
definitive numbers. From a practical aspect, it'll be happier on high
octane,
but good pump gas works fine. But did anyone ever find this number?
Somebody's
going to have to do some measuring with an engine apart I think. Maybe an
"experiment" for Cincy, who's got some heads laying around? With he skills
on
this list, and the known CR for the 2L, it should be do-able, right?
