OK so it’s not that we are worried about the piston expanding from the extra heat we’re talking about rings. The extra he will expand the piston ring it’s self and but up against each other and drag in the boar. These rings should be gapped to .024
Nippon Racing Type S (11:1) compression test readings.. 165.. 165.. 170.. 180.. 1st ring gap NPR ring 0.018 2nd ring untouched oil untouched. I'm on 11psi boost. Have you ever seen readings like this in a stock sleeve h22a motor.
I got the simular results when then i went with the super tech rings instead of the ones they come with. I just think if you go with these pistons you should just go with a name brand file fit set and be done with it.
What do you reccomend for a eoem b series build..I'm getting mixed answers.. oem rings are 200 vs hastings or npr for 40$..would like to save the money if I can..
I got a b16a2 just did a over haul due to a bad ring on the 3rd piston I decided to buy after market and my loca shop told me nippon racing rings I want to turbo in the future would those work good
Ring Gap unless ...so small that the ends touch under operating temps is .. not important ! Real life proves that ring gap is NOT critical. .. Despite Brochure babbles.
Duron Chase cross check it with the other cylinders to get an idea if it’s the ring that’s off or the cylinder that’s worn. If the ring is tighter in the other cylinders you may want to rethink either getting another block or boring over. In your case probably another block sssuming you already have pistons
@@VHBEngines lol no i bought new rings all tops were even. I filed all tops to 0.20 but one. It was the very 1st ring. I filed wrong to about 0.25 lol. My cylinders are fine. All are dead on. Acording to the old rings. Thede are the top rings. I bought cp rings. The tops were tight from .015 i believe. And the second rings are .024. So i had to open the tops ofcourse for boost.
Duron Chase if it were a build for me I’d run it. For a customer, I’d order new rings. Not the end of the world but comes down to what your comfortable with
I dont want to sound dumb but every time I try using the formula to get ring gop size the second ring is always smaller. Is this normal or could somebody help me how to get it done correctly.
I don’t use it anymore. The numbers don’t really make sense to the application. If it’s a turbo engine I’m gapping .021 or .022 top and .024 or .025 second.
sorry bout the audio tone change. i was cupping my speaker by accident

StrictlyFWD well NPR is a name brand ring company 👀
@@VHBEngines yes but but i mean a file fit set npr rings arnt a file fit set there made to expand with warm up heat.

Both of those are fine
Hi. Where do you get the chart for the nippon gnr rings for na applications. Thanks in advance
I just ordered my nippon type s pistons for my h23a. Will I have to modify anything to use the h23a rods?

hasting did the job for me :)
some people gap oil rings needed ?
One of my cylinders top ring .025 and the second is .024. The rest are in the spec. Will that be fine? Or get new rings for #1 cylinder? Chris

going to get total seal rings, used them on my high compression (11:1, lol) build on my old f22b1

Awesome thanks. I thought I was the only one note being able to do the math 👍
