NPR Piston rings

[TweeT91109]

I'm just rebuilding the motor, I was suggested by my machine shop to clean the pistons by hand and replace the pistons rings. The NPR rings set that is offered on Drift-motion look like a winner. Has anyone used these. Are they really a quality ring set? Am I going to have to order a set of oil rings?


Here is the link to the rings set.

I dont believe aaron would sell something that was of poor quality, they include the 2 compression rings a the oil control ring. Ill be using these on my build, Ive heard good things about them.

Using them on my engine without much issue. I have good compression, but my engine does seem to lose a little bit of oil (can't say for sure its from the rings). Keep in mine the top ring is chrome which is very hard, so break in requires a proper finish on the block. Hard rings+very hard iron that Toyota used on the block= difficult break in. Also, don't forget to gap and properly orient all your rings before you put them in.

Right, ill be doing a lot of research on installing he rings, and buying a lot of tools to do it properly lol.
