2.4L Pistons

[sleepydsm]

Hi. I have a 6 bolt 2.4L, and I've been researching pistons. Ones that caught my eye were from Magnus Motorsports. Black anodized, high boost, alcohol, etc. Anyone know anything about these?

why do i get the feeling that you don't know what you are looking for

Because I'm a dumbass who knows nothing. Thanks for all your help.

Decent and cheap, go for Wiseco. If you want better, go for Arias or Ross, but they are not quite as streetable (more slap). JE just sucks, stay away from them, IMO.

[sleepydsm]

I was set on Wiseco until I read something Raptor said about Wiseco sucking for an undisclosed reason. Thankyou Jet, for some real advice. A little piston purr never hurt anyone!

[AJ]

The reason Wisecos are not the greatest any more is that they started making them with the part #s and a makr to show how they should go in the engine stamped on the top of the pistons instead of being nice and smooth. Not the best way to start off with a new set of pistons on a boosted engine.

[Raptor]

Allan is right, at least about why I didn't want to use the wisecos as shipped anymore. What really pissed me off was their lousy attitude about getting ones that didn't have extra indents all over the top. They said I would have to order custom sets and wait 4-5 weeks as well as spend another 150-200 per set for them to leave the stupid marks off. And they were pretty crappy to talk to.

There are a huge number of pistons on the market that work well. I will tell you which ones I don't like. Besides the wisecos, I am not a fan of Ross or as Jet mentioned the JE's. There are many reasons for me not liking either from the things they lack to problems they have. Venolia, CP, Arias etc are all fine and will work with you on custom setups. We are switching to a piston manufacturer that at the moment I will not disclose to anyone other than our customers or potential customers. The design is much better and on every engine tested, they have been proven to add substantial power gains. If you are considering having us build your engine, call or come down and I will run through the facts and info for you.

The pistons that Magnus sells are made by Ross to their custom specs.

How do these pistons add substantial power? What is substantial power?

[Raptor]

For only a piston switch, substantial power in this case is 20HP at the crank. Accounted for by dome and ring land and skirt design. This has been proven on an engine dyno over and over. The pistons replaced were all wisecos in this case.
