The connecting Rods will work. BUT I highly suggest new rod if your going FI. Plus it you already have the motor torn apart better to do everything at once.

 

yea thats the plan. But I am buying connecting rods that say they're for the 2.2L, and I want the pistons that are for the 2.0 and 9.5:1, I am going with forged rods and pistons....I just had to make sure that if I bought connecting rods for the 2.2L, that pistons made for the 2.0L would work with those rods.

 

From what I understand they arent physically different other than hardness but dont quote me, I thought it was the crank and the pistons that change the displacement.

 

also I know that I am going to be going forced induction. if I wanted the supercharger from a 2.0L I need the supercharger, throttle body and intake manifold right? I just want to make sure.

 

can i put and aftermarket ss/sc downpipe on my honed manifold???

 

As long as it is same mounting as stock I see no reason why not.

 

i Was Reading in the GM performance build book and it was saying to switch out the 2.2l61 header with a 2.0 header.? "For improved durability it is recommended to upgrade to
the production 2.0L LSJ valves or Ferrea (part number
F1963P intake and F1961P exhaust) valves." am i undertanding this right?

 

They're talking about the exhaust manifold. If you have 07+ it came stock

 

thanks for the intel

 

All Exhaust Parts are interchangable

 

In order to use pistons for the LSJ/2.0 in an L61/2.2 you need special "adapter" rods.

GM offers them.

If you put 2.0 pistons in a 2.2 without these rods the engine wont turn over.

There is no supercharger for Cobalt.

A supercharger will physically fit on an '07 2.2, but there is no way to tune the ECM.
You'd need to use a fuel controller, go with a piggyback or standalone of some sort.

The dealership cant tune an ECM of any year.

You cant reprogram a 2.2 to think its supercharged.

The 2.2L61 , 2.0 LSJ and new 2.0turbo LNF all use completely different ECM's and only the LSJ's is tunable right now.


Also you cant install "anything that replicates the conditions of the SS". You can only upgrade to options for the car youve got. For example, most dealers wont or at least arent supposed to, reprogram an LS or LT for 17's or 18's because they arent an option, trhey are only available on the Sport/SS. For example a 2008 LS model doesnt even have 18" wheels as a possible selection in the BCM because there is no car with 18's right now.

Most dealers wont do this as GM will be unlikely to issue a VCI password to allow them to do so. GM wont issue a password because they have no way of knowing that youve got speed rated tires on your car, or that youll keep them.... So they dont allow it. Its a liability issue for GM

 

Moder Zogaz... So that is why they told me they "couldnt" change my limiter... But they did reset my speedo for my 17's which with those tires cover 3 milimeters more per rotation than stock SS/SC 215-40/18's. They set it to the same settings as those since they couldnt set it for my exact tires.

 

Yeah, they can set the speedo/abs calibration to one of 3 or 4 tires sizes(depending on year of car) 195/60-15, 205/55-16, 205/50-17 and 215/40-18 (225/40-18 when TC is avail) but this doesnt affect the speed limiting fuel cutoff. Its just a simple click with the scan tool to select a tire size. Changing the fuel cutoff is a reprogramming event that requires the car get new software downloaded from GM

Not to put too fine a point on the subject but basically you can swap anything between all the levels of car and between the Cobalt and G5, its just a matter of how much work/parts are involved.

 

Yeah, I knew that wouldnt change my limiter but shiot, I plan on having this thing til it runs into the ground, they should let me change the damn speed limiter.

 

A co-worker of mine has an '06 sc/ss coupe and he had upgraded to stage 2. Will his stock exhaust fit my '08 lt sedan? If so, is it worth the effort to swap it? Thanks.

 

Yes it work and it's work about 80 dollars and give a nice 5-10HP gain.

 

Thanks!

 

Anyone in the Phoenix, Az area have the setup and willing to sell it for less than $100? He wants $100 for just the cat-back portion of his stock system.

 

I missed this Post. They are talking about the Exhaust Valves inside the head not the Exhaust Manifold.

 

For the interior make a note that 4 door cars cannot use the A pillars in the 2 door cars without modification.

I know because I have an SS gauge pillar that I had to modify to fit in my fore dore.

 

Well i just put the 2.4 dash gauges in my LS and they work just fine... they read the same speeds, rpms, fuel and all the little lights work just fine...

 

^Badass.

 

yeah its rather cool, but you have to make sure you get one from the same year car... i think 05 and 06 were the same, but 07 is different, and my DIC doesn't work right now. I'm going to try and find one that is an 07 so it does work, but the guages look good

 

ya....i did the same..works just fine

 

Here's a quick question, are the Ion RL and Cobalt SS/SC exhaust the same? Locally there's a guy that's going aftermarket and I might be able to get my exhaust from him if it's the same.
