Evo 9 Piston rings
 

Hey guys im having a tough time figuring out what rings to run on my evo 9 pistons. The only part number on them is a e9k1, and a 50 which from my knowledge mean .02 over. They also measure .02 over from my stock pistons. I was told that hasting rings carried a set for .02 over evo 9 piston but cannot find it. The guy I got the set up from went through dsmgraveyard and there website has been down for the last couple days.

I got this response from Hasting rings
" set # 2c4558 is designed for a 4g63 and 4g63t vin code D, F. That is a 85mm bore with 1.2, 1.2, 2.0 piston groove widths. So if that is the engine code yes they will fit."

I went to total seal's website and cataloged an evo 8. The groove size for them matched what I measured on my evo 9 piston. But it looks like the total seal ring set cr4713 20 is going to take a while to get ahold of. I don't know if anyone has any experience with evo pistons on 1g rods but need help finding rings for it. thanks for any help

Rods shouldn't matter, just get .020 over rings for a 4g63 right?
IMHO just get a set of Ross .020 over rings for 4g63 and that's it. Then file them to the gap you desire.

so you wouldn't see a problem with running these? I was just worried because the thickness of the rings change from my knowledge. The oil ring on my evo piston is 2.0 mm.

I've only ever used OEM rings with OEM pistons.

Crap, yea didn't think avout being oem. I was thinking aftermarket for an evo.
