All the quotes are of RICE RACING himself talking about his enigne and NRS seals.
If your thinking about deal with RICE RACING or using NRS seals. Id think again.

"Well here is the end fruits of all of my hard work L ONE TOTALLY FUCKED ENGINE!!!!

10 psi boost, water injected, touched rev limiter at 7000rpm in 2nd gear, high 10 AFR, 10 deg ignition timing small dent on front rotor face and one totally shattered apex seal which then caused catastrophic failure to my engine and a massive bill, fucked brand new Mazda Crate Fully race prepared engine (damage list ALL end plates scored *injested broken ceramic seals* both rotors stuffed, one rotor housing stuffed ) one damaged turbine wheel on brand new TO4Z turbo charger…. One broken depressed and angry man L

Peter.

"

And more

"p.s. they have to be a fucken **** seal! As I personally have seen and had much more detonation on the stock Mazda 2mm and never had a seal shatter like this ever. The real fucked thing is almost every single engine I built in last 2 years for various people all fitted with NRS seals have fucken destroyed themselves! And I have been blaming everything and everyone as I could not believe it would happen…………….. this is probably karma on me.

"

and more

"p.s. cleaned up all the parts and the cause of failure was two apex seals breaking on the front rotor and they snapped right where the corner piece starts near the bottom (weakest part of the seal).

"

and more

"Listen to me you stupid ****!

Your APEX SEAL FAILED then the corner seal broke! I have the apex seal where it snapped off at the leg where the secondary piece joins.

It fucked my entire engine and cost me $12000 in parts and time. This is not the first time either, its happened to 9 out of 10 engines (I personally built to the highest standards *none of the others used ceramic corner seals*) and all along I have needed to tell everyone it’s not the seal fault but rather them and their tuning or some other bullshit excuse.

Now when I do actually need support this is how you treat me! Nice! I supported you and your bullshit product when no one else would, if you want a fucken enemy well you have just got yourself the worst one you could ever dream off ever having!

I sent my evidence to quite a few people (these are not my “buddies” as you call them) but ALL people who have been supporting me for many years, sadly it looks like you have chosen to not be one of them as you can’t admit (and won’t pay up) for the destruction your weak as **** wonder shattering apex seal did to all of my brand new parts! But hey I suppose the clearances were wrong, or the engine injested a foreign object for the apex seal to explode LOL.

Ball is in your court how you choose to respond from now. Remember you will cop a world of crap if you choose to **** me over on this and I promise you it will never end and I will have dozens of people who will go out of their way to support me be they customers or workshops who have all had to deal with these catastrophic failures.

If you are a man you would admit the problem and work towards resolving it, rather than attacking the most loyal asset you have ever had.

" have an apex seal that exploded into a million bits rather than cracked and it took out my entire engine, I think that is defined as “fucked”.

Add to that all of the other failures of engines I have built for various customers (me myself personally) and the time and effort others have gone to take out broken motors and strip and inspect them form me (Jake has done 2 for me) and it stresses relationships to a breaking point. These are favors that my supporters and “friends” have done for me to keep me out of the **** with paying customers who have had similar catastrophic failures. I would defined that as “fucked”.

The years I have put in sticking up for you on every forum and race track/workshop I have attended let alone phone call to others in the industry telling them, selling to them the virtues of your seals, without ever letting on the failure rate and method of failure and what it has done to various people out of the 70+ sets I have moved for you. To have an e-mail from you blaming the corner sear and a tight clearance that I gave the o.k. too is what I would call “fucked”.

Your seals shatter to pieces, they did in my engine, they did in almost all the engine I personally have built, they have done so in basically every single turbocharged car I sold the product into, but I always stuck up for you and your seals through thick and thin (do you forget this?)….. now when I of all people need some support and offer you some feedback of a very critical problem or catastrophic failure of your product in this application which is showing to be far less tolerant than even the stock std Mazda offering you are still going on with the same lines like I am some kind of retard who does not know wtf I am talking about or doing?.... that is what I would class as “fucked”.

" just today had another customer call me who is sending back a dead engine this week.

This one has 1 piece 2mm apex seals and his exact words were this as follows. “ Peter the motor has just done 1000km and was still on Jakes run in tune, I was accelerating in 3rd gear and hit the rev limiter grab’d 4th gear and it sounded like a tractor”

He looked in the exhaust ports and it has one smashed apex seal - Sound familiar? Exactly the same failure as my engine. This was fully tuned by Jake JSR and installed by him, engine did not injest anything and I built it 100% correctly. No ceramic corner seals involved. This follows off the back of the other mysterious failure of another customer of mine Ian who’s engine pictures you have and Rob commented on saying it injested something to break the apex seal, upon my and Jakes analysis no such thing took place.

"

and more

"On the apex seal front re the NRS and one piece. I have had most success on one piece but having said that have had 3 failures on engines I have built for customers all running 1 piece 2mm NRS, same story massive failure resulting in totally rooted engines.

Seems to be they are not tolerant of any level of detonation or use of rev limiters that cause misfiring or harsh engine operation.

"

and now for the pictures

so... does "rice racing" not know how to build an engine? or are these seals hes using ruining his name? I have never heard of him so I dont know.

I do know, I have never rebuilt a 13b but If I did, and it failed, and then I rebuilt 20 more OTHER 13b's after, the chances of them ALL having apex seal failure and ALL having shattered apex seals seems fairly builder error, but rather the lack of quality in the product used. I would have quit using those seals after the first 2 or 3 engines. this guy seems standup and has stood by his work and is rebuilding all these engines and taking a massive hit. i think he should def. file a lawsuit. you cant ship someone a **** product for them to use and then cost them thousands and just get off scott free, ever hear of chinese drywall? or..

All i hear is talk about a bunch of predetonation and busted ceramic apex seals.

"small dent on front rotor face" - detonation!!!


"As I personally have seen and had much more detonation on the stock Mazda 2mm and never had a seal shatter." - Ceramic is more brittle hence why they dont take detonation well.

"accelerating in 3rd gear and hit the rev limiter grab’d 4th gear and it sounded like a tractor”- Sorta similar to predetonation,i always thought hitting limiters were a terrible thing

And at the very end he answer's all these problems saying "Seems to be they are not tolerant of any level of detonation or use of rev limiters that cause misfiring or harsh engine operation" - EXACTLY! I assume everyone is tuning their engine very aggressive and getting detonation before they know it.

And as Ratjar said, after a few crap motors i would have changed out their seals and never looked back.

Im not a tuner or pro engine builder, just a regular guy.

Sounds like I won't ever be using NRS seals. I have been an avid fan of the information Rice has provided over the years.

I dont want to bash on the guy, but yea.. if you bought say, lug nuts, and they all started falling off after 3000 miles. and you replaced them, would you switch products if time after time they failed.

just startn

i think the NRS seals are fine. a few of the guys use it in the US and worship them. You just gotta know what you are doing in terms of installation. Looks like the person building these motors didnt .
a few guys i know use the NRS and one guy heard audible detonation and still survived after many many thousand miles.
