SPI 1.2mm top compression ring answers. part number inside.
So I ordered the sealed power standard re-ring kit for my 01 focus. Pull the pistons out of my new block just to find that the new top compression ring does not fit. Yes, I had the mysterious 1.2mm top compression ring. After hours on the phone with sealed power and ford dealers, everyone says they only list a 1.5 top compression ring. Finally I talked to a very helpful lady named Lisa at hastings. She knew my exact problem and said that the 1.2mm compression ring was for the european market engine. I'm not sure how much truth is in this but either way, the hastings part number for the 1.2mm compression ring kit is 2C5150. That's for the whole ring kit. She also gave me a part number for just the individual 1.2 ring but I don't have it on hand at the moment. I can post it later if needed.
Another breakthrough was with the ford dealer. A gentleman named Bob at my local ford dealer emailed somebody that makes a lot of money at the ford corporation and confirmed that ford does carry the proper 1.2 mm top compression ring but they don't list it as an option for this car or the escory. He ordered a set in just out of his own curiosity and confirmed that it is 1.2 mm. I didn't get the ford part number from him but I will do so tomorrow if anyone needs it.
I hope this helps everyone out a little bit.
