2.2 to 2.4 Upgrade

Can I just change the Air Intake and Throttle Body out on my 2.2? I have a 2008 2.2 with no modifications. I want to put the 2.4 Air Intake and the 2.4 Throttle Body. I was online and saw that the 2008 Cobalt Sport which was a 2.4 made around 171 horsepower.

Im pretty sure you can do this but you wont be making 171hp thats with the bigger engine and you will still have a 2.2

You can put the intake manifold on no problem but youd have to tune for the throttle body. Minimal gains not worth the $400 or so to gain 5hp

You might also need a harness adapter. Some TBs have 6 pins, others have 8. ZZP sells the adapters.

As a stand alone mod, don't expect much. But it's a start.

With enough bolt-ons and a proper tune, you'd be able to put a stock SS/NA behind you. You might see up to 180ish chp.

Optimum horsepower setup for an NA 2.2 would be something like this:

CAI
LSJ (SS/SC) TB w/adapter & harness
LE5 (SS/NA) IM
longtube header & catless DP w/wideband
catback
HP tune

I have the 2.2 l61. 2.4 intake manifold and TB injen intake, full exhaust, trifecta tuned and I dynoed 140 hp and 126 ft/lb of torque. Trust me 180 is very ambitious for a non boosted 2.2.

Also taking a couple parts off of the 2.4 doesn't make your 2.2. The 2.2 and 2.4 is the actual engine displacement, not just a name.

180hp (170whp) is indeed on the higher end, but it is obtainable on bolt-ons alone. With the stuff I mentioned a post below, you should see those numbers.

Maybe your tune was weak? 140whp really doesn't sound like much of an improvement over stock. 126tq doesn't make much sense either. Do you have a wideband? Was it a canned Trifecta tune?

Yep its trifecta, but I datalogged a few times For vince and kinda got everything dialed in as much as possible. I might be doing a gen3 LE5 swap soon which will open me up to HPtuners and some real power. But the 140/126 numbers are fairly reasonable. Stock numbers were 112/98 so its nearly a 30 hp and 30 tq gain. To gewt those higher numbers on a 2.2 you're looking at a full internal builld as well.

112/98? What dyno were you using and did you connect the right wire to read rpm signal to the right ignition coil wire? Mine with my intake/header/lsj downpipe/catback/no tune read 141hp/139lbs tq. A cobalt ls stock should be roughly 120ish hp/120ish tq stock. I used dynojet with the ramp that raises and lowers.
