2.4L LE5 Internals HELP!!!!
Hey guys Im new to this site and I have searched and searched for internals for the LE5 and I am at my wits end trying to find anything other than pistons. I know in my model it has forged internals but im just looking for a website, catalog or something in case I ever needed anything in that sort. I would appreciate it if someone can please point me in the right direction that would be great.. TIA

The 2.4 is a bit of a step child in the cobalt world but if your pre-08 you have good components to start with. Knowing your end numbers would help. Some are going to 300HP with stock internals and did for a while.
Stock crank, Molnar rods and Diamond pistons will make for a better bottom end than the block can handle.

now quick question, so the OP doesn't encounter problems.
Does molnar rods are compatible with diamonds pistons? or wiseco piston?
If I recall correctly, there was an issue where a brand would not be compatible with another brand. So you have to get all in one. I might be mistaken but I think it was zzp rods or pistons?

From the Sportsman Ecotec Race Engine Book.
The 2.0L LSJ and LNF ECOTEC engines have forged steel rods similar to Small Block Chevy “Pink Rod.” The forged steel rods are made of high quality material and have a cap screw, 23 mm small end, and a full floating bronze bushing. These rods are available through GM service parts. These rods require an aftermarket piston set to work with the stock 2.2L crankshaft. Alternatively, Eagle and Manley both offer a CNC machined H-Beam rod which is an exact replacement for the stock 2.2L rod. (Fig. 8)

I know what it is. I was with GM when they started doing it and boasted it as the next best thing.
The video I posted covers the most important process of Sintering the component

I have a 2007 Pontiac G5 GT 2.4L. i came to this forum because the G5 forum doesnt get into explanation like this forum does.. if I were to SC my car other than the kit ZZP provides for the 2.2/2.4 what would I need and how much boost can this car handle with a stock bottom end?

You said how much psi can it handle. Psi is not power. There’s no “psi number” that will blow your motor. It based off of horsepower and torque. And stock 2.4 motors have been over 400
