jonathan909 Posted July 22, 2021 Share Posted July 22, 2021 Not my own problem; a good friend is in the middle of overhauling an EJ20 (of provenance unknown) and is having a little trouble sourcing rings. I haven't confirmed any of this, but he says his pistons use 1.2mm rings top and middle, and the oil ring is 2.0mm - but that all the kits from Rock (for turbos) are 1.2/1.2/2.5 . Where is he likely to find the set he needs? Quote Link to comment Share on other sites More sharing options...
el_freddo Posted July 22, 2021 Share Posted July 22, 2021 Tried an engine machine shop? Take a piston to them to size up. That’s how I got mine. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
