quick question

do 4efe and 4efte piston rings the same ?

Some mecanics say they are different (but don't know differences...) and other say they are the same

i would say they are the same, but looking on toyodiy, there are a few different part numbers for the rings between years and cross referencing the number only brings up 4efte fitment.

i cant see what would be different apart from maybe the ring gap specs, but that wouldn't mean a different ring would need to be used!!!
seems an excessive cost to have lots of different rings when they could easily standardise.

this was my opinion. they will use different part numbers, just for the fun of it. but produce one standardised product

I assume for forged pistons the rings are totally different yeah?

most likely as the rings will be specific to the piston type. probably only manufacturer differences though, so a 74mm piston ring for a ross forged piston will fit all 74mm ross forged pistons, but they may not fit wiseco 74mm pistons. I may be wrong though, but that's the way most companies do things.

I always use 4EFE rings. Hastings are better than OEM.
They are 1.2mm 1.2mm 3mm

Ring land thickness on forged pistons are the most of the time the same but the depth is not the same.
