im new as far as upgrading my cobalt ive been looking into geting the stage 2 kit for my cobalt s/c but i dont wanna pay 700 so ive been looking into outsourcing for parts i found a pully and belt and im looking for injectors that would work with the factory flash all i got was high flow injectors and i was wondering if i put 60lb injectors in would it still work with the flash

 

You can not use bigger injectors of any kind on the factory tune. Will run like crap.

Any time you get bigger injectors you need a new tune.

 

Are you looking at getting the GMS2 kit? You can get a ZZP stage 2 kit for less than half of that.

 

yeah ive noticed the zzp logo alot on here what website can i got to or do i just search zzp stage 2 kit,

 

and would i still have to get a tune or can i take it to gm with the zzp stage 2 kit and get a flash would it still work like that like i said im a noob im into street bikes but i went down at 120 a year back and i traded in the 2 wheels for 4 so im learning all over again break it down in crayon

 

i found the zzp kit what do you think of te stage 3 if its as relable as it says im willing to go that route but if im getting in to far over my head with it ill stick with th stage 2..... i liv in an area with turbocharged cobats and they have an attitude nothing wrong with that iwould as well but i want a spercharged balt thatll have enough power to stand up against them if its not possible like they said well let me know i seen zzp has a turbo kit swap and id be willing to save up for that let me know what you think

 

It all depends on what the turbo balts have done to them, if they have full bolt ons and a high psi tune then then factory supercharger wont beat it without something like nos, so u have 2 choices get a bigger supercharger the tvs or turbo swap. Id personly say get the tvs and all the cooling mods to go with add some meth and get it tuned by someone that is good with these cars, u can check the dyno section for a liat of people with all kinda mods to give u an idea of what u want to do,

 

you won't be beating a bolted and tuned tc with the m62. End of story. Even with just a tune a tc will give just about any m62 balt a run for it's money.

OH SORRY I FORGOT TO SAY WITH NITROUS! Most people don't want to run nitrous. Turbo is still the way to go, turbo LSJs can put down some great numbers if you're that determined to beat a TC.

 

Turbo LSJ>LNF

 

i was wondeing with the stage 2 kit from zzp which is better to go with the tensiner pully or shorter belt........ and after install will the gm tune for there stage 2 kit work the same with the zzp stage 2 kit

 

the gm stage 2 tune will not work on the zzp kit, gm comes with 42s and zzp comes with 50s

 

I have GM stage 2 injectors for sale for 70 bucks with a harness in the classifieds.

 

I'm just giving ya a hard time Tommy.

 

implying I'm arguing that. I completely agree
I know it was supposed to be a "sarcastic caps lock" hard to convey sarcasm over the Internet.

 

agreed.

OP just slap a turbo on your go and go have fun, or even a TVS. I really like my turbo setup now, its fast, but the TVS was just fun in general.

 

lol I know. Damn internet

 

Go with ZZP's Stage 3 Kit.

It's not too difficult to do and it comes with a tune.
best bang for your buck. . .

Or you can buy the parts separately and find someone near you who can tune you.

 

OK so i was dooped by the dealership but i tracked down the guy that owned my car prior to me buying it i had him look over it and it has stage 2 injectors and a 2.9 mps hub and pulley im at 7 pounds of boost he said i should be at 12 pounds with the set up i have he looked everything over quick but didnt have much time to give it a good look through i have a fuel regulator as well and i spliced the hose and ran a hose from the boost controller modual and spliced it with the hose connected to the regulator its running strong now with better fuel and that splice but im still only at 7 pounds of boost any ideas or recommendations or warnings or any advice really anything will help...... i also have a cold air to put on the car it has a stage 2 tune hopefully all that info will help you help me i appreciate it guys

 

how much power does that produce im at 240 with the stage 2 kit and tune not a custome tune just the flash from gm

 

If ur running only 7 pounds of boost something is wrong with ur car, stock the car runs like 10 to 12 depending on where u live.

 

yeah im trying to figure out whats wrong with it the upgrades i have is stage 2 injectors 2.9 pulley and a fuel regulator i have the fuel line that runs to the regulator spliced with the hose that comes from the boost control modual i had a diagnostics ran just a basic and its says bank 2 lean which im thinking is just the regulator would it be a bad boost control modual that would be doing that cause it just hits a wall at 7 or could it be a leak somewhere i just have no idea before i knew that i had a stage 2 kit on it i ran mid grade fuel in it not knowing but i dont think that would do anything could it be maybe a seal somewhere on the supercharger or a bad belt maybe the belt is slipping i just really have no idea

 

its gotta be a boost leak somewhere ..... ill start with the a boost leak test and i hope its only the supercharger seal fingers crossed for tomorrow

 

im zac.

do you have cats in your exhaust?
