What pistons?!
Alright.. here's the deal. My rings are shot on my LS block, I believe.. but either way I am rebuilding it. Getting it bored out to 81.5mm, ARP headstuds, new oem gasket, new bearings, Eagle Rods w/ 3/8" ARP2000's, and I -was- going to get CP 9:1's.
Last night I was at BW3's with a friend who has a fully built 400whp CRX. He has pretty much the same setup that I want to do, except his block is ERL sleeved. The head that he had on there was old and he just didn't want to mess with it, so he bought a brand new (from Honda) ITR head. When he was swapping the head, he noticed that on the #4 piston one of the edges on one of the valve reliefs(forget which) was burnt off! He said he had JE's that did the same thing.
So then I went searching about sanding/buffing the sharp edges down, and in this thread (https://honda-tech.com/zerothread?id=191739), Earl states that doing this can make your piston out of balance.
Now, I don't know what to believe, who to believe, what pistons to get.. I know nothing anymore haha! I'd like to hear your guys' experience and professional knowledge on this subject, as I would like this engine to last for as long as possible.. (only going to be pushing 250-275 to the wheels... 203/193 now).
Summary: What pistons won't burn off the edges of the relief? Should I just sand down the edges? Will this take them off balance?

Re: What pistons?! (ccivic)
"sanding" your pistons is called deburring, its just taking the sharp edges off of the piston. people do this to their pistons because the sharp edges heat up faster and can cause detonation ( which is not good ) i deburred my pistons and i had no problems with them. i made 472 whp on stock sleeves. i cracked a sleeve and when i pulled the head, pistons were 100% mint condition ( aside from the scarred side skirts due to a GAY machine shop honing the cyl walls for me ) but the tops were 100% perfect. id like to hear more tech about how deburring the pistons causes them to be off balance..can anyone support this??

I've heard that mentioned a few times around here abouthte CP's, but no one really mentions why. Back when I was shopping for internals parts, I heard a lot of good things about CP, but once I had them I started hearing bad things aout them.

Re: (Muckman)
too many people making alot of power on CP's for that to hold water. Companies dont make defective parts any more than people assemble defective engines. Is the glass half full or half empty, do you think people would rather blame a company for a build gone bad or themselves, alot of people want to try to build engines, if it was that easy there would be alot more low 10 high 9 second cars out there.

Re: (rhd)
CP makes good pistons.........they are just over advertised on honda-tech as if they are the only pistons to use......
personally i would choose arias, wiseco, JE then CP..........in that order

Spare me the bandwagon nonsense...if you can point out some physical difference that would make the CP worse then other brands names I'd be happy to hear about it. Why would I want to keep myself from buying a good product based on how many people used it? I got CP's because earl built my motor and that's what he likes to uses in his engine builds. I heard a lot of good things about them, and just one problem. That was with the valve relief not having enough "meat" around the edge. But just one problem isn't enough for me to get worried.
BTW udders are ******* on a cow...utter is the word you are looking for

there yah go, all you had to say was valve relief. I hate it when people try to use bandwagoning as a reason not to use a product.
Unfortunately I didn't hear about the valve relief on the CP's being thinner then other pistons until after I had my motor built. If I had known this a long time ago I might have looked into getting some Arias or Wisecos instead.

Re: (rhd)
Well, everyone can talk about what they think is best. I will talk about what I have used and the pro's and con's about each:
Arias : These are my first choice simply because I use them day in and day out, I measure them all the time, I custom order them and they come in perfect and they have never let me down. Tolerances have NEVER been off on any of the Arias pistons I have purchased They have always been right on! I switched from JE to Arias on Ed Bergenholtz Mazda6 and noticed MUCH more reliability and strength! They are my top pick because I have used them all and they have worked the best for me under the most extreme conditions, also because I have numerous motors that have well over 60,000, 70,000 miles and more that have had no issues running everyday in NA and boosted street applications.
JE : JE is a good piston, but I noticed that I get far more wall scuffing ( black death ) and had to run the pistons much looser than I wanted to. They have very good tolerances and are designed with performance in mind. I do not like some of the ring pack designs offered and I hated that the designers at JE would send me different rings that what I wanted, without consulting me first. Then they changed the entire skirt design without my knowledge and that was the end for me!
Wiseco : Again, a decent piston and something that I have plenty of experience with. I have notices that you can run a tight clearance and not get wall scuffing, but the ring lands have always proven to fail on me at high RPM and high HP. The pin location on the piston leaves much to be desired as far as strength, but overall a good piston for moderate performance. Tolerances are OK, but I have seen variances between pistons in a set.
CP : A quality company that likes to produce a ton of product. Again, a case of a large coporation pumping out product and marketing it extremely well. These are a good piston, but the tolerances are nothing that I would consider perfect. The pin boss is beefy and strong and the cam design seems to work well in most situations. I have never pushed the CP as far as the others, but I am sure it is comparable to the JE!
Ross : A very strong design, but also a very heavy and cumbersome piece of metal. I have never had any really great experiences with Ross. All I have ever been able to do with their pistons is make an ashtray out of them. Sorry, not trying to be mean, but it's the truth. I would never recommend them to anyone.
SRP : If you are going to run a street car with very low boost or NA then they are OK, but do not expect them to survive anything that I would consider performance. I like to use these in a semi-built replacement style engine build as stock piston replacements!
The other manufacturers I only have a handful of experience with, not enough to determine their values. I work with these manufacturers all the time and have a lot of recorded info on tolerances, variances between sets, overall product performance, reliability and customer service. Arias is by far the leader in all aspects IMO. Hope this helps.

Maybe if you think you need 600whp for performance. Several people have ran SRP's reliably for years with 400-500whp. The 2618 alloy that the other pistons you have listed are made out of is only about 15-17% stronger than the 4032 the SRP's are made out of. You can run your tighter tolerances with the 4032 and not worry about scuffing either. My next build, however, will probably be CP or Wiseco pistons, but I have no complaints about the SRP's I've been using and would definately recommend them for anything 400whp or less.

Re: (RyanCivic2000)
Turning into a very informative thread
So.. right now I'm pretty swayed towards Arias.. and there's a deal going on by a sponser for $700 shipped for H-beams and Arias pistons!
Anyone else?

Re: (boostincoupe)
I can talk all day long about why I choose one pistons over another, but I am being completely dead honest when I say I think Arias is BY FAR the best afyter market piston you can buy. Sure they don't have the 3,000,000 square foot buildings that some do, but they do have something that most others don't , and that is HEART and VALUES. They have been updating their equipment with some of the finest pieces available, regardless of cost, to be able to bring the very best product. When I started into all this, I wanted to do a lot of research on what piston company I wanted to use and do a buy-in with them. After years of research, experience and good ole trial and error, my money went to Arias on the simple fact that their product works, they have great customer service, great to do custom stuff and excellent performance and tolerances.
I know I may be rambling and there are plenty others out there that like other manufacturers, but I swear by Arias and the results are stellar for everything I have used them on! From drag racing records, to Bonneville World Speed records, to exceptional street and daily driver performance, they have worked for me

For a GSR head, there is no piston I would use over a Endyn Rollerwave.
For all others, whatever. I've heard of Arias pistons having looser clearances and being louder than the rest of the bunch. Anyone with more recent firsthand experience with their SHELF pistons care to elaborate?
SRPs may end up being the best for a low power-daily driven type application because of the tighter clearances you can run with their lower thermal expansion rate.

These are a good piston, but the tolerances are nothing that I would consider perfect. The pin boss is beefy and strong and the cam design seems to work well in most situations. I have never pushed the CP as far as the others, but I am sure it is comparable to the JE!
Ross : A very strong design, but also a very heavy and cumbersome piece of metal. I have never had any really great experiences with Ross. All I have ever been able to do with their pistons is make an ashtray out of them. Sorry, not trying to be mean, but it's the truth. I would never recommend them to anyone.
SRP : If you are going to run a street car with very low boost or NA then they are OK, but do not expect them to survive anything that I would consider performance. I like to use these in a semi-built replacement style engine build as stock piston replacements!
The other manufacturers I only have a handful of experience with, not enough to determine their values. I work with these manufacturers all the time and have a lot of recorded info on tolerances, variances between sets, overall product performance, reliability and customer service. Arias is by far the leader in all aspects IMO. Hope this helps.</TD></TR></TABLE>
Funny that this guy is "sales@goldeneaglemfg.com" and the exclusively sell arias pistons.
But maybe that's just me.

Could you please tell me how a company that is only 5 years old can have 20 year old technology? That is a ridiculous statement.
I will make you this offer. Pick out any Wiseco piston (or ANY other brand) you want. Come to Calif. I will pick you up at the airport. We will pick up lunch to go on the way over to CP. You will get a tour of CP. Anywhere during the tour you can stop and point. I will eat my lunch right off the floor where ever you choose.
We will then place your piston into their half million dollar laser measurement machine. You will get a complete printout of your piston to the nearest millonth of an inch. THIS INCLUDES FLATNESS MEASUREMENT INSIDE THE RING LANDS. No other company can even measure like this. You can pick any CP piston in the building. We will do the same test on the CP. You can compare the results to standard for yourself.
ONE LAST POINT If your tune-up is correct, you can have a piston with 50 sharp points on top. NOT ONE OF THE POINTS WILL BURN OFF. If your tune-up is wrong and the top of your piston is perfectly flat, you WILL burn a hole in it.
