Hey guys Im fairly new to the Cobalt world. I've owned 2 Cavaliers one of which was an 2.2L Eco & another of which im performing the same swap into. I have a few questions about what this car can handle. I see everyone wanting to make big power in these cars but does anyone know how much they can actually handle. My questions include;

How much power can the Axles handle?

Whats the maximum amout the fuel pump can supply?

What are the limits of the injectors?

How much can the engine internals support?

How much does the Head flow?

What are the lift & duration of the Cams?

What is the trim & like specs for the stock turbo?

I know the fuel pump can supply over 2000psi in pressure but @ what volume? The rods are forged steel according to GM but the pistons are still cast. That combo doesnt make much sense to me but I kno that on the original 2.2L eco in Cavi's the rods were the weak link so mabey thats why. I would love to make big power with my 'balt but i dont want to start breaking things. Any help is appreciated.

 

It seems that only time will tell how much power the lnf and the rest of the drivetrain will stand up to. one thing is for certain if you beat on it constantly even with just a tune and 275 whp you will break something soomer or later. If you are easy on it it might last 200,000 miles
