Wiseco vs. Je
Which do you turbo guys favor? I know I can't go wrong with JE but Wiseco has the 89mm that I want for my 97 Prelude for less than the JE pistons. Thanks, just trying to finish off my turbo project.

Re: Wiseco vs. Je (Anubyss)
I can only offer an opinion.
JE is by far a better piston that Wiseco. I would at least consider SRP if you are looking for a low cost alternative. But dollar for dollar JE is the best bang for your buck in forged pistons. Here is a post from a friend of mine who I have found to be invaluable as a resource.
1) Endyn- These are simply renamed off-the-shelf Wiseco units.
Wiseco in my experience is the least technichally advance piston
company. They seem to have seized up the fact that if you forge and
machine round thing from aluminum, people will buy it. I can't
discern a lot of understanding beyond that. In kart racing there are
many piston sizes, but as with a honda the factory japanese pistons
are of top quality but only come in a few sizes. Once the liner got
past the last factory size we could not race the motor anymore, as it
requires Wiseco (or other low-tech piston makers) pistons and they
were not competitive. Not recomended, as they are heavy compared to
the best pistons, and have poorer thermal performance which manifests
itelf in less controlled expansion with heat. Endyn is fond of them
because they are inherently the less expensive, so when he marks them
up to the price of the premium quality custom pistons he claims them
to be, he makes more money. They are neither premium nor custom, they
come sealed in a box from Wiseco, untouched by Endyn. One guy hybrid
board orders 5 sets, for several different applications. Some were
suppossed to produce 12.5 in a particlar motor, other 11.5 in the
same engine. All where the exact same identical part.
2)Arias- Old school V8 hot-rod piston maker, not bad quality buy not
exaclty a cutting edge design and metalurgy. Certainly strong, but
they expand a bit wildly requiring increased piston clearence and
subsequent piston slap. V8's use more piston clearence, and have
plenty of cast iron surrounding the cyliners to muffle the slap.
There are better options.
3)SRP-Not a bad choice, low cost line manufactured by the real piston
maker...
4)JE- The real thing, with cutting edge metalurgy and design similar
to what people like honda have. Light and strong, with the best
expansion characteristics allowing the tightest cylinder clearence.
Not cheap, but clearly better than Arias or Wiseco. It's not clear
exactly how much difference there is between the JE branded units and
the ones SRP sells, the SRP version is cheaper. To be honest I'd
trust the SRP's more than Arias or Wiseco, and I'd get the JE's if
budget permitted.
5)Other Choices- I'm sure there are some, I think Ross is making
import pistons now also. They are top drawer like JE, but very
costly. Like the JE they are available on a truly custom basis, not
the handful of Wiseco part numbers Endyn sells. To be honest JE is
the piston of choice, and they sell sets for hondas at fair prices.
I'm not sure how much farther I'd look...
I trust what this guy says. Take an opinion for what its worth....2 cents.

Re: (Anubyss)
i compared a set of srp's by JE to wisecos and the wisecos were far tougher looking. they are really stout and thik in the upper half. Tunning is the key but if **** went down hill for a few seconds i feel the wisecos would take the beating alot better than the srp's by far. i cant comment on je's tho have never seen them in person

Re: Wiseco vs. Je (Anubyss)
dont forget if you by wiseguys pistons via endyn they could be sportsman quality, these guys that make domestic pistons make like ten different qualities. lets compare apples to apples, wiseco uses the same machine stock as JE, ask JE.

Re: Wiseco vs. Je (RGAZ)
Umm I was always under the impression that JE pistons were low silicon (or is it silica?) content and therefore requied looser clearances and more cold piston slap, and that SRP pistons had higher silicon content and could run tighter clearances than the JE ones??
I swear i read that here or on another board about 3-4 months ago..

Re: Wiseco vs. Je (Anubyss)
^^ does anyone know what's going on?? Someone w/ authority set this issue straight. It's probably been resolved but since we can't search, only whoever already debated this knows the result. I was under the impression that JE/eagle was the "can't go wrong" combo brand wise and thus the H-T standard... I've got no complaints on my set, but I'd like to know if I can build another motor for cheaper. TIA

Re: Wiseco vs. Je (tonydatyga)
Just some extra info. JE are good pistons there is nothing wrong with them. People use them all the time and they work great. Especially when someone I know sprays a 300 shot on them.... (Well tuned V8). They hold and are still working great. Can't say the same for his SRP though. Detonation is VERY bad. I myself am kind of biased to ROSS though because they make only what you order so they perfect YOUR piston they. They are also the pistons used in the SALEEN mustangs and they are getting into NASCAR now. Just my .02 cents.

Re: Wiseco vs. Je (sweettooth)
I would think more focus should be paid to the tuning aspects of the motor and not just "what is the best piston can i get for my motor" kinda deal.

Re: Wiseco vs. Je (RioNinja)
Endyne/Wiseco's got my vote.... they look awesome compared to some el sloucho SRP's I had at one point.
The SRP's ended up being out of round <used> and the machinist said this is common in the SRP line from the semi-forged metal they come from.

Re: Wiseco vs. Je (Anubyss)
JE and Wiseco Both use Low Silicon Aluminum which is stonger than heck! The low cost SRP Low Compression pistons use High Silicon Aluminum which can become very brittle under high boost! Arias uses High silicon aluminum for majority of their low compression pistons also! High silicon content pistons tend to melt with high boost! although, what is really wierd is that SRP uses Low Silicon in their high compression All-Motor pistons!
High silicon aluminum is great for running tight piston-wall clearances only because they don't expand as much as low silicon pistons! These pistons usually call for .001" - .003" piston-wall clearances. They tend to be a little quieter also!
Low silicon pistons require a .003" - .0035" piston-wall clearance for expansion, but they are rock solid! I have heard JE low silicon pistons in several cars and they aren't that loud to my surprise!
Like I stated before, both JE and Wiseco are great pistons! You can not go wrong with either!
