What is the best pistons on the market. There are wayyyy to many choices on the market now it makes my head hurt trying to make a choice.

 

i doubt you will get a definitive answer to this question. its not going to be a landslide where everyone tells you to go get xxx brand pistons. some people may have had good experience with one brand but someone else may think that brand sucks. some good brands to look into would be: cp, je, and wiseco

 

Ok, Let's start here....forged or cast?

(it would actually be better to ask how deep your pockets are and what your application is)

 

you would almost be better off asking what pistons NOT to use. every one of the quality pistons is a solid choice. mahle, wiseco, cp, je etc

the actual choice is do you want 4032 or 2618

 

you would have to put Mahle first hey ? Anyone would of thought you were hinting something j/k

 

i think "Sealed power" pistons are really good.

 

engine?
setup?
goals?
any information?

 

Not to get off topic, but I went ahead and typed "What is the best piston in the world?" into the Google to be a smarty-pants. This is what came up on the first page (may not be safe for work - but not too bad)...

OP - As stated above, please list more information.

 

you can't beat google...

 

JE FSR (I am mildly biased) http://www.jepistons.com/Articles/10...d-Pistons.aspx Very cool.

 

wisceo for me reliability and proven on the market nowdays

 

"Better" for what?

what is the purpose of the car/engine (daily driver, drag, time attack etc.)?

2618 aluminum is stronger than 4032 aluminum (about 16-17% greater tensile strength and about 12% greater fatique endurance), while having a greater coefficient of thermal expansion (about 14%). The 2618 aluminum is also about 3% heavier.
The 2618 pistons will require greater piston-to-cylinder wall clearance than 4032 pistons, and will be a little noisy and there will be a bit of piston slapping until they heat up. Also, with the 2618 aluminum, there will be more oil consumption and blow-by on cold starts. Finally, the lower expansion of the 4032 aluminum means it should have better wear characteristics.

For street cars, the 2618 pistons are fine if you don't mind the downsides (noise & oil consumption), but they likely will wear faster. The 4032 pistons also are fine for street use. They will take longer to wear, they will be quieter, there will be less blowby when the motor is cold, etc.

The 4032 allows for tighter piston to wall clearance (less heat expansion) which results in generally longer life and quieter operation.

If the engine is going to be boosted hard and frequently, then 2618 may be better.

Piston Alloy Comparison
4032
High silicon
Low expansion
Tighter piston-to-wall clearance
Quiet Operation
*Less ductile
More stable & consistent
Longer life cycle
Harder

2618
No silicon
High expansion
More Piston-to-wall clearance needed
Noise when cold
*More ductile
Higher resistance to detonation
Shorter life cycles
Softer
*(ductile is malleability related to how brittle the material is less=more brittle)



SRP- 4032
JE- 2618
Mahle 2618 & 4032
CP (Carrillo) 2618
Weisco 2618 & 4032

hope this helps

LOL, was subconscious

 

Its gonna be a b16 shooting for a 400 hp weekend warrior. Thanks mike for the info! Ill probably go with cp 9 to 1

 

Go for Mahle, trust me there more than fine... Even Racebum will tell ya...

 

I'm new here but have been using CPs for quite a time and they are champs.

 

I use CP's but Weisco and JE are good choices

 

Ya for 400whp you are going to be fine with any of the mentioned choiced. If it comes down to price, Wiseco pistons will be the cheapest. They will suit your purpose just fine.
