Compression, pinging, and problems...

Sounds like your timing is off.  NOT the disty timing but the cam timing.
Make sure the t-belt is on correctly then I would suspect the cam to cam
timing.  BUT, FIRST, check to make sure the bolts for the disty are in the
right place since there are more than one way that the disty can be mounted.
HTH!!

   This is a request for help!

My engine is a 16v. Balanced PL block that has been bored and stroked to
equal 2008cc. Pistons are forged JE units, crank is a stock 2L unit. I'm
running my stock 1.8L head, and stock 16v CIS-E fuel system/ignition.
According to an online compression calulator I'm running roughly 11:1
compression. I use strictly premium fuel (93 octane here in Tallahassee) and
Tally is basically at sea level.

Currently my car is set to run VERY, VERY rich (puffing black smoke when I
get on it) and the ignition timing is back as far as it will go without it
totally dieing off the line. This is the only way I can even come CLOSE to
stopping the pinging, and even still it pings some on really hot days.

This sucks, for lack of a better term. Please help me find a way to enjoy my
very wicked engine, but keep it in one piece. There is nowhere I know of to
buy race fuel, and I drive the car daily and that wouldn't always be
convenient. Would cams help, or no? What can I do here other than lower the
compression with a thicker head gasket (I'm running a stock 9A headgasket,
btw). I am on a budget here, so please keep uit reasonable. 11:1 isn't THAT
insane, is it?

My car BARELY holds an idle, it's so rich. It does die at idle on occasion,
actually. But if I lean it out even a smidge, it pings more.

I'm really in need of help here. Thanks in advance to those who can help.


Joshua Hignight.
