between Hypereutectic Pistons and Forged Pistons and what is stock?
Forged for 99% of applications. Being that you have a '90, it came stock with forged (assuming you have the stock shortblock).which would you go with?
I thought hypereutectic pistons were aluminum? And according to wikipedia I was wrong - it's not the nickel content, it's the silicon content. Not sure where I got the nickel thing from...ya hypertunic pistons are more suseptable to cracking under the smallest amount of detonation which is why they say not to use them with nitrous and boost where detonation happend much more oftan. i am sure they are lighter then fordged steel but i doubt they are lighter then my fordged aluminum pistons.
