from some honda tuners here in canada the pistons that work best for boost are the Arias pistons, mainly becasue they are the only one s that work with the oil squirts in the cylinder , all other ones you have to modifly or make new for other pistons so you dont get any


quote my tuner

"Yep, the bottom of the piston slighly touches the top of the oil squirters. I know that CP, Wiseco, and JE all touch so the oil squirters need to be removed. Look into it before you buy the pistons. I believe Joel Smith had this problem with his pistons in the Gsr block. The B16 with Wiseco pistons that I just built had this problem so I had to plug the oil galley at the oil squirters. I know this applies to at least the 3 I listed. Arias is your best bet cuz they dont touch at all"


now, he said thid was back in 2004, has there been any changes with pistons designs lately? what other pistons will work best with squirters, becasue my tuner builds ls/vtec motors and all b and d series motors for boost and performance, its what he does

any more info to suggest???

I heard Arias Sucked because of the alloy used for this Piston is very soft and expands and retracts more than a CP or Wiseco would! I personally used Arias before and have not had a problem but then again the motor did have blow by and after the pistons were removed the cylinders were all scared in the same patern. Im also interested to see if anyone else had this same problem!!

mitchell_2kSiR

i'd go for any pistons, i just would like to mainly know a little mor info with other pistons and the oil squirters delema

non-VTEC

i know for wiseco pistons you need to bend/move/remove/modify the oil squirter's on B18C bottom ends. wiseco makes the piston skirts a little longer and they can touch the squirter's.

most other brands are usually pretty good. but that clearance should always be check with aftermarket pistons anyway. plus most engine builders remove the squirter's all together since forged pistons usually run cooler so the oil squirter's are not really needed.

there is no "best/better" piston. they are all pretty good.

Endyne has the best off the shelf piston IMO!!!!!!!!!!

My tuner said something similar, that they cant be run with tight tolerances and most engines with arias pistons have A LOT of noise and sound like diesels which can make it a bit hard to tune due to faulty knock readings i guess...

ive been using arias pistons pretty much exclusively in every build...not a single problem with them at all...zero...zilch...none.........ask the people who have actually run them rather than trust a bunch of hear say on the net

my tuner currently has a car at his shop that uses arias pistons, it does indeed sound like a diesel...

streetracer6rpt

ive got arias pistons, no problems......

mitchell_2kSiR

so then what pistons do you recomend for me that i wont have any porblems with oil squirters and stuff

Why have you built many blocks using all the different kinds of pistons? whats your basis on that?

ExospeedAMcrx

Any piston will sound like a "diesel" if the block is not machined right. LOL.
Just a slight mistake on measurements on the final bore/hone can cause excessive piston slap with ANY piston.

Most piston brands out there are good. If they weren't, then only a couple would be in business right?

blinx9900

ehhh, i guess you guys are right, i cant blame the piston for a noisy motor cause it could have been the builder, but my tuner said most arias pistoned engines are like that, he did NOT say they dont hold up though, on the contrary, he said its just as strong a piston as anyone else like ross/wiseco/JE.

mitchell_2kSiR

a few people here in saskatchewan are running arias pistons, 22lbs on a dart block bored to 2.2L(street/strip del sol), ls/vtec 11 lbs on arias pistons(drag car)

they recomend them to me jsut cuz they've both had issues with other pistons for their oil squirters and found arias are one of the few that you dont need to modify the squirters

And a few tuners here in town have shown me pictures of how bad the piston slap on the ARIAS unit! To each their own I guess

ExospeedAMcrx

ya to each their own. we've made over 800 hp on off shelf turbo Arias pistons many times. They work for us.

People would be suprised what pistons some of the faster cars on H-T run. Arias in particular. We've used them in a couple different makes of cars with zero issues

0bd1_Kanobe had more misinformation in his first post than I have seen in a long time. ALL PISTON MANUFACTURERS USE THE SAME MATERIAL!!! It's either 4032 or 2618 depending on the application. Hell, most get their forgings from the same place as well, and their coatings... So to say that it's material is just plain ignorant, sorry. Go do your homework...

Wiseco and CP do seem to have the lion's share of H-T builds, and have good names. I'll pretend that CP's didn't used to burn up if any rogue oil entered the cylinder, and that all complaints were eliminated after a reportedly 'unrelated' design change. Wiseco has been making pistons since WW2, has been proven to have very good piston characteristics by several indipendant publishers (not just Honda), and rarely see issues. I do recall the 2 cracked Wisecos, but it was after 43k miles of use at 400ish WHP. IIRC fresh pistons was all it needed. I use Wiseco's, and at ~.0035" clearance, the head is FAR louder (can't hear any cold slap).

Anyways, I'd not pick a forged piston because it can use the oil squirters or not. In most cases, the better thermal properties of forged aluminum over cast means squirters are not required. Given that more oil pressure can do more for you (and that the turbo basicly saps you of some), its usually a good idea to plug the squirters.

Only you can weigh all the pros and cons and decide. I usually say use what your tuner recommends, and what the locals have success with. The locals are proof in the pudding, and the tuner's experience usually trumps other brands' innovations. Just know most tuners live in the present, and don't focus ONLY on how the motor will work 50k miles from the initial tune date.

My Wisecos and JEs never touched my oil squirters, and I've had multiple sets of Wiseco and JE pistons.

LastGenEK

I Have a B18C with 81.5 mm Wiscos and all i had to do was stick a screw driver in there and push them into the center of the bore more and all was good


for wiscos. I love the coated skirts and the size of the skirts

</TD></TR></TABLE>It is irrelavant what Pro FWD car those pistons are in! If I have a problem with a pistons I am not using it I stated in my first post that I my self did not have a problem with the piston but had blow by and found out why when I tore the block apart! Like I said Endyne has been good to me and will not use anything else BTW no need to get defensive just stating what I expirienced with Arias Pistons
