is there anythin i can do for performance other than a cai and exhuast for my balt..? i have a 2.2 auto and everybody keeps tellin me there is nothin i can do for tuning so that makes most all the other performance stuff for the car usless because i cant tune for them... anything would be helpful..

B&M Shift plus....or trade it in for a 5 speed

 

I really hope hptuners gets software out for you guys. Our 2.2's have so much potential that us j body guys take advantage of being able to tune.

 

it all depends on what direction u wanna go with your car. do you just wanna make more horsepower, or do u wanna improve the ride quality and handling a bit too? figure out what you wanna do and what direction you wanna take your car in, and then we can help more.

 

^^cant agree more...

 

im wanting to do handling ands horsepower... im kinda leaning on doing the power part first though... i want to be able to beat mustang gt's and stuff like that.. dont get me wrong the car is pretty fast to not be a sport model.. ive beat all kinda honda's toyota's and nissans but i want more than that.. i seen the thread bout an auto to maual swap but it never said that it can or cant be done.. if i can make that swap then its something i'll do..

 

who said you cant tune.. you can tune. Go build a turbo setup and get the AEM piggy and tune away. people make piggys sound like they are going to kill your car.

 

if u just wanna go with horsepower to start, go with a full exhaust.

intake, header, downpipe, and catback exhaust. if u go by the brochure, ur looking at over a 20 whp gain. but we all know those gains are always a bit exagerated.

a good set of tranny mounts from CobaltPerformanceParts.com is another good mod. and i would definately suggest the B&M Shiftplus. from turbotechracing.com. thse both help your car to use more of the power you have.

to go with all these mods ur definately gunna wanna upgrade your tires. since ur looking for performace, u should definately buy a set of performance tires so all the power you have is getting put to the ground by a set of good tires.

in the end, the possibilities and list of mods can go on and on and on... lol it all depends on how deep your pockets are and how far you wanna take it.

 

yea i was wanting to get custom pipe ran all the way from a header and get duals put on it.. would 3" pipe be to large for the the car..? i already have z rated tires on the car.. i put them on when i got my 18's put on it.

 

There's a lot you can do. Exhaust manifold, intake manifold, new down pipe, b&m shift plus or tranny interceptor. I hear the interceptors are fun. Then there is internals. Rods, pistons, cams, cranks, or pretty much swapping internals with Eagle parts.

If you do a lot, you can run into a lot of problems with changing the computers and voiding any warranty. That's why i stook with just the intake and lowering mine. I got the GM intake and the dealers never say it voids the warranty. I haven't told them about changing the springs. Haha. I hate car dealers.

 

i never thought bout gettin a piggy and tuning. the only problem with gettin a turbo is that i've heard that the auto trans wont hold up to all the extra power..

 

the auto is supposed to be able to handle more than the manual from what i hear

 

I know there a few good turbo kits out with a good piggy back for it. I know alpine developments made a good kit that comes with the ecu and there is one with a garrett turbo, but i'm not sure if that comes with a piggy back. Search for alpine developments. They have a video and pictures of their turbo on cobalt and show a dyno on video. I checked it out a long time ago.

 

if you want to run with mustang gts and things of that nature just save your money and go turbo(yes you can turbocharge an auto). You can't tune the tranny in certain aspects, but for the most part it's not that big of a deal. If you're worried about it get a higher stall tc. You're going to spend alot of money going n/a peice by piece up to the level you want to be at.

As for handling, get yourself some good motor mounts, some thicker rims with some good rubber, and some springs/struts or coil-overs would be even better if you can shell out the money. Possibly do some things to stiffen up the chassis if you want.

Also if you go with one of the usual turbo kits sold around here it'll come with a flash tune for your stock computer setup. No piggyback needed. So no need to go in and splice wires and all that other stuff. But you will need to get a piggyback to tune further should you feel the need to up the boost and such.

 

My piggy back works fine for me, turbo FTW

 

so the turbo kit for the m/t will work on the auto with out causing any problems? i had read in one of the other threads that under normal drivin that it would the auto trans would shift like really hard kind of like dumpin the clutch in a m/t through every gear.. as far as n/a goes i was thinkin bout gettin a fully built motor and head and thats what i was worried bout the tuning for..

 

i'm pretty sure the turbo kits dont fit the autos because of the difference in shape and size between the transmissions. the auto transmission may interfere with tubing or various parts of the kit because it is larger/differently shaped than the manual.

ha ha i have no idea for sure but im just talking. it makes sense to me

 

well i was just goin by one of the threads i had read on here bout trying to turbo an auto cobalt.. they said that a turbo would make the auto shift really hard under normal drivin and eventually mess it up and that the auto wasnt made for much power..

yea you may be right bout that.. i didnt think about any fitment issues.

does anyone know if the auto to m/t swap can be done? and is there any way to remove the 4 grand rev limiter that the auto's have?

 

The problem with the auto is that the tcm will actually sense the extra tourque from the turbocharger and adjust the trans shift pressures accordingly. Since the turbo will more than likely put it outside of the stock spec range you'll basically have max shift pressures all the time which will cause slightly harder shifting. It'll put extra stress on your clutch packs and your trans mount, but it should be pretty easy to counter-act with a higher stall tourque converter.

I'm pretty sure there won't be any fitment issues putting the mtx turbo kit on an atx car from looking at the pics. But I'm not positive either. At the most you might need to get a different hot pipe made.

 

do they actually make a higher stall converter for the cobalt? just wondering cuz i've never seen one on any of the sites i've looked on..

 

go talk to a tranny shop around you. To tell you the truth I'm not that fluent with tourque converters but I know it can be done. As far as I know a converter is a converter. The only difference in any of them is the stall speed.

 

thanks.. i'll deff check into that..

what size piping should i run on my car? i want to get it custom done cuz i want to have duals put on it..

 

if you're planning on doing some serious modding, it might be worth your time to check out a megasquirt setup.
