Do forged pistons hold up well enough to live for 100,000+ miles?
Do forged pistons hold up well enough to live for 100,000+ miles?
I've never had a forged motor. In the past they all had cast or hyperureutic pistons.
Rebuilding an LS1 that will see a lot of daily driver time for the RS. I know forged pistons are what most folks use when they rebuild. With reasonable care and moderate street use, how many miles is a forged piston set good for? I've heard the hyperureutic (sp) pistons tend to live for far more miles.
Thank You

Forged pistons will hold up relatively well...however you must exercise some care with them.. ie cold start up they tend to rock a little in the cylinder until they have warmed up and expanded. so be gentle when cold.. they do have a tendancy to scuff more then your higher silicon content pistons. so the actual cylinders will see some extra wear and needs to be monitered over time and checked for runout.. there are a couple options out there though.. the stronger of the 2 are your 2618 forgings which are superior for strength in higher horsepower apps where cylinder temps run excessively higher, and then there are the 4032 forged pistons which are forged and have excellent strength yet a more daily driven characteristic in higher silicon content for tighter build clearances and better scuff resistance.. a good compromise in my opinion.. depending on your goals for power and how you plan on getting there should dictate which you ultimately decide to use. excessive power will best be suited on the 2618's.. and as they say if ya wanna make big power your simply gonna have to accept its gonna be expensive.. and freshening up over the course of a few thousand miles will be required. good luck hope this helps!

I would definitely go forged. They are also lighter than hypercrap pistons as well. Go for the lightest piston/rod combo you can
Just let the car warmup before beating on it (good practice anyways) Many cars came with forged slugs. (early 90s 5.0 Mustang is one that comes to mind) and I have seen them at the track with 200K miles on them

Let me shed some light on this before it goes overboard. The mustangs did have forged pistons in them and they did live for a long time but, that is not the same forged pistons that you will be getting from your choice of manufacturer. Those pistons in the Mustangs were purpose built forged pistons that were designed to factory spec's. Not the same spec's that JE, Diamond, Ross or any aftermarket pistons manufacturer makes theirs too. Those factory forged pistons used a lot tighter piston to wall clearance, this in turn let them live for over 100K. You will be hard pressed to find a aftermarket piston that will do that. Also factory skirt profiles are very different than the aftermarket but that is a story for another day. Moral of this story.......you will get a lot of miles out of a forged aftermarket piston but it will not last as long as the factory forged by any means.

Ok...this was in a DSM I built with Aries Forged Slugs....they slapped a little till they warmed up...I usually just turned on the car went back inside finished fixing my hair and gathered my briefcase and by that time motor was up to temp.....car lasted 120,000 miles before some ******** in Greenspoint ripped it off and stripped it to nothing and left it in Conroe...point is they can last if you're just careful w/them...and these pistons saw 30lbs of boost and a 75shot on top.......I was never "Easy" on them when racing....when I wasn't racing, I drove like my father....nice'n slow and just easy.

Chris, what's would you say the "typical" life for an aftermarket forged piston like a JE, Diamond, Wiseco or CP would be assuming good care is taken?
If I knew the stock pistons could survive the engine dyno testing we're going to do, I'd stick with them.

Josey, you can get them to last if you treat them right. That is not the norm for most people though.
Wade, it is hard to say what the exact life would be. You will get a long life out of them most likely. They should go a good 50,000 with no problems. Now if you spray them, life is in your own hands.
