This is from a guy who is giving me **** for building the bottom end, saying I don't know what the hell I am doing, etc.:

"I would get a daily driven car, because forged pistons dont last for alot of miles under hard expansin and contraction conditions. http://1trick.stangnet.com/faq/pistons.html That link prolly dosent do much and i couldnt find the 1 i was looking for That explains the study... Ask around though because i have heard of studies where forged pistons last 25-40K miles before "wearing out". Most people dont drive there cars hard 25,000 miles with boost in less than a year... A boosted honda with forged pistons shouldnt be daily driven or driven that much period, thats why professionals change there stuff after a little bit."

Can anyone here confirm this for me? I understand sort of, but I think it's a bit overstated.

 

he doesn't have a built motor, I can tell you that just from that statement.

Building the motor is fine as long as the assembler has done his/her job of being diligent in their assembly. It will last for years to come.

Stop listening to this guy is all I can really say

 

i'm hoping to get 100k miles out of my built motor.

 

Subaru's have come stock with forged pistons for a hundred years.They seam to run for more than 40k.As well as most bmw's and benz.

factory turbocharged cars are forged, think 2jz.

 

up

 

forged lasts as long if not longer than cast.

 

I was just told that supra internals are cast not forjed, except the crank.
