i have no clue... cai? exhaust? right now im thinking of a kn drop in... for the time being

red_wing_2121

I have a 2.2L with a K&N drop in. You don't notice much of a difference in power, only a tiny tiny bit. You will get about 2mpg more, though (at least I did).

intake, exhaust, header, ECU tune (when it comes out)

intake, good header ceramic coated with 2.5" collector, 2.5" high flow cat (direct bolt on on the way from Random Technology, 2.5" exhaust, Unichip tuning is on the way

cobss187

go out and buy the ecotec build book, check the part number list thread for the number on it. most of the stuff in that book is used on the 2.2 and there is also a lot of stuff about the internals of the car and not just boost, good luck man.

Basic bolt-ons are good for starters. That seems to be pretty much universal.

intake, header, exhaust, cams, ignition

lol i got header, car, 2" pipes, intake...... npow im stuck i think im going to go more visual now while im waiting for the unichip

afireinside1582

hey biohazard, whats your hp now?

I think biohazard would greatly benefit by changing out the 2.00" pipe with 2.5" pipe. If you have 2.5" pipe header back you'll get more benefits out of the header and the high flow cat also need 2.5" exhaust axle back with muffler.

In the GM Build Book, everything is referrenced FOR boost. In the Stock to 250 HP, it basically tells you to just buy a supercharger.

Back to the original poster...

What are you looking for as far as power wise? How much money are you looking to invest in your car?

There is no point in buying minor upgrades like an intake if your goal requires you to do something much bigger. If your girl is not realistically in your budget or idea of willingness to spend, than this would be a perfect time to not even modify your car cause it would be a waste of money.

Basically what I'm saying is make a goal and make a plan. Doing this now will get you prepared for the future. If you need any help, just contact me.

2 1/2" exhaust system is just too big for the 2.2 ECOTEC naturally aspirated. 2 1/4" would be much better.

IMO easiest with best HP/$$ ratio buy an N2O kit and spray it with a 75 shot. I've done a couple L61s with the ZEX wet nozzle combined with the Airaid powerplate(200-554-P) with very good results.
ZEX kit#82021 (approx $500)
If you already have a CAI you can skip the TB plate and just tap it (NPT tap inluded with ZEX kit) and thread the nozzle directly into your CAI. 2 hr installation time.
I've used the .021" Fuel Jet/ .040" NO2 Jet combo (the largest provided) on the 2.2 with ZERO issues.
Later on you could probably go 100+ shot with pistons/rods and a tuning solution.

have you ever had any TPS issues on any 05+ Ecotecs?

WopOnTour

Which DTC exactly? APP yes, TP not common... (in an 05 there's actually twin TP inputs)
WOT

IonNinja

the reason for my question was because of this post

8th post down by Zinner

would you recommend a WOT switch instead over the TPS switch setup that the Zex kit uses?

WopOnTour

I've never had problems with the ZEX programmable TP sensor on the 2.2 L61, but on the 2 LSJ cars I've installed nitrous, they were "staged" and we therefore used a pair of adjustable boost pressure triggered window switches.

There certainly could be something to what Zinner is saying. The pair of drive-by-wire throttle TPs have 2 "opposing" voltage curves. TP1 starts at about 4.5V and goes DOWN, and TP2 is at about .75 and goes UP as the throttle is opened. The PCM looks to check the correlation between these 2 voltages so if one of them is being affected by the ZEX TP module, it could set a DTC and put you in Limp Mode. BUT the ZEX unit didnt affect the voltages AT ALL on the cars I've used it with.
To use the ZEX you would want to tap into TP2 which is the light blue wire going to the the throttle body.

oh, sorry... dont want to go the nitrous route either... anybody know anything about an ecu flash? a buddy told me they could do it at a rhinolinings... like 400 bucks and i keep the tuner... so i can get good gas mileage or more hp

NJHK

Sorry but what is a rhinolinings? What do you mean by "keep the tuner"?

Getting your computer reflashed isn't going to yield you power if you have basic modifications. Usually reflashes (example GM's reflash) is boost oriented...it can read boost, send the proper amount of fuel per PSI and changes ignition timing accordingly. This is something that the computer will know you need.

Reflashing an n/a motor won't do you any good unless you know what you need...do you need more fuel? do you need less fuel? do you want to have your timing advanced? This is stuff YOU have to figure out and even if you do figure it out, it could totally change if you put another part on your car...you could go from needing less fuel to needing more fuel and a reflash might not adjust to what you need.

Also, I highly doubt that some random company is going to even be able to flash your computer.

afireinside1582

a buddy told me that if you go to a rhinolining place (they spray on the truck bedliners, do exhuasts and other mods) they have some little computer that they hook into the cars and can adujst certain things to add hp or mpg. and when theyre finished, you keep the computer tool they used, so you can mod if you want, and if it needs to go to the dealer, you can return it to stock.

FRIARPOP

seems like they would charge you an ass load to keep the tuner.

NJHK

That's probably for trucks...diesels even. They have alot of programmers available for their vehicles like that.

to my knowledge nobody has a programer for the eco-tec's yet, i may be wrong but i have looked around and the gm lan system is very complex and i think that is what is holding up all the turbo kits from coming out. Also, the only reason for a flash of the ecu is if you changed your tire size so you need to recal your speedometer, or you have added Forced induction or NOS, or you wanna get rid of your governedspeed or you wanna get ridd of your revlimiter, there is no magic button that makes your car have more hp or more fuel economy. Untill you change stuff on your car there is no need to mess with the ecu, GM did that at the factory.

NJHK

Actually HP Tuners has a device out for the ECOTECs and I think for the Cobalts as well (I know they have it available for the Jbodies but that's a different story).

CivicKiller98

the communication for engine and tranny control is different on the 05+ cobalts than on the jbodies.

hptuners is going to start work on the cobalt 2.2 after they are finished with the 2.0 and 2.4
