190e 8v engine specs anyone?? W201

[SPEEDEXX]

I need some engine specs for the 86 Mercedes 190e 2.3 8v.

What are the Valve Sizes? Intake and Exhaust?
What is the bore and stroke? 95.5mm x 80.8mm??
Compression ratio

Gearing in the Automatic Transmission and Rear End Ratio.

Thanks in advance.

I could only find some of the information you're looking for, and some of
that you'll have to decode, but here goes:

Bore - 95.5
Stroke - 80.25
Displacement - 2299
Compression Ratio - 8.0:1

Here's where it gets more difficult - the numbers for valve sizes were shown
as a pair of numbers for each measurement. They were situated one above the
other with a horizontal line between. I'm not sure if this is supposed to
indicate a min. and max tolerance or something else completely, but here
they are:

intake length - 114.70/115.10
exhaust length - 115.60/116.00
width of intake valve seat - 1.8 - 2.5
width of exhaust valve seat - 1.5 - 2.5

Sorry, but I couldn't find any numbers for the gearing of the auto. tranny
or the rear end. I have them for the 16-valve, but not the 8-valve.
