Mike2JZ Posted April 25, 2017 Share Posted April 25, 2017 Whilst trying to find some piston rings to go into a 2JZGE stock bottom end (86mm) I found that some ring suppliers sell either GE or GTE piston rings, whilst others are selling rings that can apparently fit either. Looking at the Toyota EPC, the piston rings have different part numbers: GE (13011-46040) GTE (13011-46050) It seems that both the GE & GTE piston rings share the same thickness dimensions of 1.5 X 1.5 X 4mm Looking at the US Repair Manuals, you can see the following: The US manual shows that there is a distinction on the ring end gap. The GE ring gap being a slightly 'looser' fit The original Japanese repair manual for JZ engines shows the following: Here the ring end gap is shared between both GE and GTE engines. I don't have a set of GE and GTE rings to hand to test what gap they come with straight out of the box. So a few questions: a) Has anyone got any experience buying and installing rings advertised as fitting either engine into a GE bottom end. b) If we take the US specifications as truth, then presumably you could run GTE rings on a GE bottom end. And even if the ring end gaps are slightly tighter out of the box, it would still fall within the acceptable 2JZGE end gap range specified in the manual, with some extra meat on the ring if a small grind was required. However using GE rings on a GTE may not work if the rings are indeed 'looser' . Has anyone done this before? Thanks Quote Link to comment Share on other sites More sharing options...
np89 Posted April 27, 2017 Share Posted April 27, 2017 Only difference in a GE and GTE block is oil squirters. GTE rings will be fine. Quote Link to comment Share on other sites More sharing options...
AC93 Posted December 20, 2019 Share Posted December 20, 2019 Just incase anyone else follows up on this thread.. I am currently rebuilding my GE bottom end, bought a engine gasket kit but need piston rings also. Part numbers have been super-seeded: GE - 13011-46041 GTE - 13011-46051 My local stealership want £292 for GE rings... I'll keep hunting haha Quote Link to comment Share on other sites More sharing options...
steve spedd Posted December 20, 2019 Share Posted December 20, 2019 Have a look at NPR piston rings. They are much cheaper and to my knowledge they make them for Toyota... Quote Link to comment Share on other sites More sharing options...
AC93 Posted January 8, 2020 Share Posted January 8, 2020 Managed to find a OEM set on eBay from the UAE, delivered in 3 days and less than half the price of the stealers here. Result! Quote Link to comment Share on other sites More sharing options...
