Metro XFI Score!

You should see if the 2nd compression ring from the std piston fits in the groove of the XFi's piston. Don't even have to install it, just measure the ring thickness.

If it does, I'd personally have no problem ordering a set of total seal rings and only using the 2nd compression ring. I've never left piston rings off a piston in an engine before, but that's no reason not to start, right?

The XFi groove looks wider in the pic for some reason, but it's not. Top rings are 1.2mm, 2nd rings are 1.5mm (not present on XFi) and the oil rings are 2.8mm. I believe this applies to all Suzuki G10/G13 engines.

Out of curiousity, I got my old 1985 Honda Civic service manual out. They also left out the middle ring on the 1300. Same design compression ring too, angled and overlapping.

Has this been done by anybody other than Suzuki and Honda?

Rebuild them both

Gasoline Fumes: most excellent information & pics posted. Good stuff. Thank you! The side-by-side photo: very nice.

I wasn't aware of Honda doing it on their 1300. News to me.

And Johnny has a point: do 'em both!

EDIT: I actually owned an 85 or 86 Civic hatch, probably with the 1300 (the 1500 was the "S", right? I know mine wasn't the "S".) I'm embarrassed I don't remember the details of that car, but I only owned it a couple of months before the head gasket went and I cracked the head. Had it repaired and sold it after that. Other than my Suzukiclones, it was the only other car I had that got fantastic fuel economy. I really liked it before I blew it up.

The Civic DX Hatchback had the 1.5l along with the slightly sportier 1500S. At least in the US. And I'm not sure if the 1.3l in Canada had the single ring, there were quite a few differences between the US and Canada versions. I had an '84 Civic Wagon until rust took it away from me.

Next rebuild is a Swift GTi engine for my other '94 Metro. I have plenty of engines I can rebuild, but only two good Metro bodies.
