Great pictures of a Geo Metro Xfi

Click on the link for some great pictures of what a nice 1991 Geo Metro Xfi looks like. If you look at the pictures you can also see the difference between the normal 3 piston Metro version and what the two pistons on the Xfi look like:

HEY! that didn't look like GM approved coolant!;)

seriously tho, nice detailed pics.

what's the advantage of a gapless piston?

Gapless? Does that mean gapless rings similar to TotalSeal?

I can understand that two rings probably reduce drag in the bore vs. 3 rings. I wonder if there is a significant difference in blow-by though.

I've read in a few (reliable) places (that I've lot the bookmarks for) multiple rings are more to allow for bad break in and extra longevity. and double up to cover the gap in the ring

as for the coolant, the metro never used a GM engine and was years from being bought by GM in 91. if anything, it oughta be toyota red coolant.

I like the cam comparison. XFI is a lot more aggressive looking.
