definitely should go aftermarket pistons, bearings, etc... what im saying is you should replace anything and everything that has been known to go bad in a stock 2.5, save you time and money, oh and a headache in the future... just ask Ed from EQ Tuning what kind of headache i went through...

We use Wiseco forged pistons on both 2.0 & 2.5 liter engines.
Fun fact: It usually costs the same or slightly less using forged pistons vs OE pistons.
Fair warning: Non OE main & rod bearings are becoming VERY difficult to source.

What mods do you have and/or planning to install with this motor?

The worldwide ACL bearing backorder is definitely putting a damper on things right now! We decided to switch to Cosworth bearings for our builds for the time being.

We don't use drop in pistons; all pistons/cylinders are precision bored/honed.
And it's still usually cheaper to use forged pistons.

It costs about the same using forged pistons if you use drop-ins without boring and honing the cylinders to the proper bore for the forged piston. Going the more precise route and setting the bores correctly usually gets more expensive, but is well worth it especially if the car will ever be tracked.
