Title: C85 pistons in O-200
Post by: go ez on March 07, 2006, 01:36:18 PM

Has anyone installed C85 pistons into an O-200 to give a higher compression ratio.

Was it successful, any snags or problems?

Any advice  would be gratefully received.

Thanks

Title: Lycom pistons

I refurbished my 0-200A last year and put 8.5:1 lycom pistons in.
They cost me $860. It was money well spent. My climb is now 1200 fpm plus and top speed improved about 15 knots. I looked at C85 pistons and it was told to me that the piston tops needed to be machined into a chamfer. I decided to let the piston experts do it. The folks at Lycom were easy to deal with. I did need to call them on the correct way to assemble the rings.

Did you have to do any machining of the rod   or does the std wrist pin fit
Thanks

I used the 0200 piston rods and cylinder pins stock.
