RB25DET piston rings

[s13point5]

i need piston rings for my stock RB25 pistons. anyone know where to get them? also does anyone know what the ring groove widths are?

It MAY be in the FSM, I doubt it though.

Call up JE and pretend like your interested in buying a stock set of pistons. They maybe able to tell you.

Check that your pistons are ok, because mine looked ok, but it was the I guess ring lands that went on my motor and scored my cylinder BAD!!

there are several companies that can make rings up for you, the problem is you need to get your pistons out so you can measure on usually turnaround time on getting a custom set our rings made up is about two weeks and a six-cylinder with a good high-quality rings usually run around $120 $150 a set, total seal is pretty accommodating about making rings up for turbo applications and has a good turnaround time. You need to know the thickness of your rings grooves and the diameter of your bore and also make sure they know it's for a turbo application.

how do i go about measuring the thickness of the ring grooves? im staying stock bore. just gonna hone the walls. so my stock bore is 86mm correct?

Bro,Take your motor to a machine shop.Where they can measure and bore/hone your cylinders properly so you don't mess up.Gonna cost you a couple bucks, but at least it'll be done right.

You don't need to bore unless you're going with larger pistons. A hone will work fine and the link Coolwhip provided has a decent price. I looked for rings and my machine shop couldn't look any further than their USDM parts catalog. Make sure you still file-fit the rings in the bores after the machining is done.

motor is already home from the machine shop. called up total seal today and ordered a set of rings. ill have the rings by monday. and i know to file fit the rings. assembly is gonna be fun but cold. i hate winter.
