JE 213918 turbo pistons

[Blake051300]

Are the new "improved" je 213918 pistons any better then when they were cracking? I was told it was just a bad batch but I know of 10+ sets just from one builder that were cracked. JE says the one produced since have no issue, but I have heard otherwise. The reason I'm checking into this is because I can have a set for nothing. (I know I should just buy wossners) I didnt plan on doing pistons just a spacer plate and head studs but with the price (free) it makes me think. What is your experience with these pistons and is it a waste of time to bother. My bike is going to be running 6-7 lbs, its a street bike with no water injection and runs pump gas.

i have an older set in mine with no known issues
and who can turn down free?

[cdhoroho]

if not then id love a set for backup??

Stock pistons will take over 400hp and none have cracked.

I got the same pistons on my bike.. still freshly built motor with over 500 miles on it no known issues.

[texas-buzzard]

Sell them, your stockers are fine for 6-7lbs boost.

Wow, this is a mix of opinions??

What they don't want you to know is that is it NOT a new, improved piston. It is the very same piston without the "scallop cut" done on the top. In other words, they did one less machining operation - making the piston itself heavier - and are trying to pass it off as a totally new piston. It is not. It is the same poorly designed and ill-forged Wiseco blank machined by JE.

It may or may not crack. There are plenty that have not. There are plenty that have. I've got six cracked sets myself - too bad I don't smoke.

I have not taken apart a motor for inspection that did not have a cracked set in it. But keep in mind all the motors we have taken apart were all making over 500hp and the customers were using it. If you use these pistons for a street bike you will likely not have the cracking occur, but then again, neither will the oem Suzuki pistons.

I have seen them cracked in Stage One turbo bikes that were making less than 300 at the wheel. Rich, your comment that "the customers were using it" I think applies here. Every set that we saw cracked came out of bikes where the customer was really riding the bike and using his boost a lot. A totally street bike might be the only exception where I could use these pistons. It just wouldn't be my bike! Would you put crappy and/or bald tires on your car because you got them for free? One other thing - who in the world builds a turbo bike and babies it, riding like a Honda Spree or something? If you can't "appreciate" your turbo, and use it to its potential because of weak parts, why even bother? You should have just left it stock.
If you use these pistons, you are going to be thinking about it every time you boost the bike. Wossners are the better choice.

[Blake051300]

That's the straight forward advise from an experienced builder that I was looking for............
Frank, thanks. Stockers are gonna stay. It would probably cost be a couple hundred thousand to buy new pistons?????? (It's called a divorce, I've spent alot of money lately)???

I am not saying street bike riders do not "try" to use the power, if your bike is making over 300 hp and its a stock length street bike, when trying to apply all your power you will wheelie or spin, resulting in lower power output. My referral to the stock pistons were based on a theory, that if you are knowingly installing a set of pistons that have cracking potential, vs stockers that do not crack, why even take the engine apart?

The Wossners are the logical choice for high quality, aftermarket pistons, they can be bought at a very reasonable price, and come std with lateral gas ports, HD wrist pins and coated skirts, all three of these options you will pay extra for from any other piston company. We have installed these pistons in bikes that have made over 600hp time and time again, and are used in many top land speed bikes and prostreet bikes.

What he said . . .

[cdhoroho]

to clarify what i was saying i personally havent taken mine apart to see if there is an issue
I personally will build to use wossners next time but on my budget i cant afford new pistons yet
if you dont need them pistons id definately think of getting them from you as a set of throw away for my prostreet bike
it sucks not being sponsored so freebies and cheepies is all i can afford lol

Sounds like you might want to research them before you have issues

You'll be throwing them away, all right - after about six runs.

well how about sponsoring this privateer lol
untill then guess ill have to run em till they cause damage
then set in the pits pissing and moaning lol

i just pulled the motor apart and inspected them after the 500 miles, again no problems as of yet.

We have not seen them actually cause damage, per se. Of course, running the motor on boost with cracked pistons is a scary thought. FYI, JE did not consider the cracking to constitute what would be called a "failure". They blamed about 16 different tuners for not tuning the bikes right, and basically tried to blame everyone and everything other than themselves for making a crappy product. In the end, they countered that their turbo pistons were not designed to go over 300 hp. If you race the bike at all, they will crack. But again, they won't do any damage to the motor. You would be the first if they did. I went over 5,000 miles on my Ultra with no problems and did not discover the cracking until the motor got torn down for some tranny upgrades. Knowing what I know now I could never use their product with confidence or recommend and/or sell them to a customer!
