why didnt you look at them before you bought them? how much did you pay for them?

150

 

So you have no idea what kind of pistons you have? Therefore you have no idea of what compression your engine will yield with them? No idea of piston to deck height or piston to valve clearance???

Oh god..........take them out and buy your self a set of pistons and make sure you know wtf you're getting.

Its "ok" to do this guessing **** with little stuff like exhausts and shift ***** but god damn. buying unknown pistons?? wtf!!!

LOLZ, FYI i asked to see what brand the pistons are. i didnt ask for compression ratio, piston to deck height, or piston to valve clearance. those i can find out myself, DOUCHE. there are method you can use to figure it out, if you didnt know! if you dont know what brand the piston are then dont post, IT'S AS EASY AS THAT!

Yes, brand is much more important than those things I mentioned.

Anywho, they look pretty similar to a p30 piston, but no I don't know what brand they are.

okay thanks. i know brand is a major issue, that why i'm asking HT to see if they ran into these pistons before cause I DONT WANT TO USE THEM IF I CAN'T FIND OUT WHO MADE THEM!


forgot to mention, these are aftermarket forge pistons. and these are the only pistons i see with a groove between the exhaust valve. so hopefully someone here happen to run into these.

 

They look like wiseco's. Could also be JE's for obvious reasons

is there any specific design? groove? marks? etc? i can look for to know for sure?

 

Looks similar to a JE.. but the intake valve reliefs don't look like JE's.

There isn't any castings on the inside of the piston?

No castings... maybe probe?

nope there isnt any casting inside the piston. i know CP has their stamp inside the piston, so these arent CP.

 

you are expecting people to tell you what piston it is by looking at the top?

how about you take the pistons out and give us some measurements so we have a better idea of what the [freak] we are looking at.

thanks noobie.

the reason why i didnt take pics of the side or inside of the piston is cause THEY ALL LOOK A LIKE! THE ONLY THING THAT STANDS OUT FROM THIS PISTON FROM THE OTHERS ARE THE GROOVE BETWEEN THE EXHAUST VALVES! DOUCHE!

don't post a "DOUCHE" comment cause your a moderator. if you wanted more info, you could have just asked. didn't think it was that big of a deal to find out what brand the pistons are.

also, i'm not a NOOB. been in the honda scene since bodykit were TIGHT! LOLz. and i lost my pass. for my old S/N.


ANYWAYS, if you actually look at the piston you know that they are HIGH COMPRESSION pistons, that why i posted in the ALL-MOTOR forum and not the FI forum. if you really want more details (which probably won't even do any help) then they are:

84.5mm
compression ratio 12.6.1

 

those are 12:5:1 MAHLE

these are wiseco's version

12:8:1



these are JE's 12:2:1




those are mahle's Gauranteed!

can you enlighten us on what this motor even is?

what is the compression height? dome volume? valve reliefs?

and fyi, we were trying to help you, however, most people tend not to like helping people who can't help themselves.

ever consider looking at the different piston company websites and comparing photo's?

i'll post a douche comment to someone who is being a douche to people who are trying to help.

take the piston out and look under it. I believe JE has a stamp somewhere under there.

thanks, for the info and help. but like i said earlier they're no visible stamp of the makers. the only visible unique design from this piston from the others is the groove between the exhaust valve. i already tried looking at different company but cant seem to find a exact picture of the pistons that why i'm asking here. i wasnt trying to be a PITA. i just wanted to verfied what these pistons are before using it since it got FREAK over on them.

can you verified it with a pic?

 

tried but cant find one ive used 2 set's trust me dome cc's are 6+

12:5:1 b16 head
12:9:1 -13:1 Gsr Head

brb let me see if i can find a pic

 

they look like endyn rollerwave pistons to me (custom spec wiseco)

but it's hard to tell just from the piston domes.

check here: http://www.theoldone.com/compo....html

 

thats not a wiseco piston.

 

definitely not a wiseco, imo. mine and other wiseco's i have seen do not have the divider between the intake valve reliefs.

 

i'll grab more pics in a bit. just took a look at the bottom and it doesnt look like the roller wave. the top does tho.

here is one of the builds i found in an old pic with mahles









i think they might be in the 11;1 compression range these above were 12:5:1
in an LS block with a 91 prelude b20 crank

 

Looks like ENDYN RW's. Look at the exhaust side of the piston.

 

new pics!!!the top does look like RW but the bottom doesnt, will atleast not the all-motor one. however, the bottom looks like it the FI one.

 

they look like endyn roller waves but on the other hand why would seller only want $150 for non used endyn's...ive seen them go for $300 used
