I will be building my new cobalt 2.2 to handle a M62. I have been looking on here and i need some questions answered and i will also make this my build thread. I work at a shop so i know about cars... My final plans on this car is to make it look like a stock ss with front bumper rear bumper and skirts. I then will want the motor to handle the GMPP stage 2 S/C package.. Please help me out if i missing anything guys or will need anything..

M62 of course
supercharged intake manifold
LSJ throttle body
Front mount intercooler
After market motor mounts
CAI
tuned
Gaskets of course.
What the **** is a heat exchanger?
I seen everyone had one of those that
did this..

will i need after market pistons and rods and rings? I was looking into that too. I reaaaallllly dont want to go into the bottom end of the motor though..



Please help me and I will contribute to making a badass 2.2 SUPERCHARGED Cobalt

 

If you stay with the stock pulley on the supercharger than no but if you really want to run the pulley from the gm stage 2 than I would suggest pistons and rods
a heat exchanger is an water to air intercooler for example a radiator is a heat exchanger, you will need one for your setup I suggest getting one from ZZP
you need the heat exchanger because the cobalt ss/sc intake manifold has a built in air to water cooling system to keep the boosted air cool and we all know the cooler the air the more power you get

I would also sugest that if your going to really put power on the engine that you do some cooling mods like duel pass end plate for the intake manifold, you could also port the eaten M62 Supercharger to get lower air temps

for a supercharger setup you will need
2 Bar or Higher Map Sensor
M62 Supercharger
LSJ throttle body
LSJ Intake Manifold
60lb or 80lb Injectors
LSJ Belt Depends On What Size Pulley
Wideband A/FR Gauge
Belt Tension Relief Tool
Worm Drive Clamps
10' 3/4 Heater Hose
LSJ Intake of some kind
Dexcool Coolant
IC Pump Bolts M8 X 1.25 X 25
Idler-Alt Bracket M8 X 1.25 X 25
IC Pump Bolts M8 X 1.25 X 35
Tensioner-Alt lwr M8 X 1.25 X 35
Tensioner-Alt upr M8 X 1.25 X 40
Intake Mani bolts
Manifold Brace
Manifold Brace Mounting Bolts
Intake Manifold Brace Threw Bolt
LSJ Alternator Bracket
Alternator Bracket Bolts
LSJ Upper Radiator Hose
LSJ Idler Pulley Assembly
IM-Head Gasket
SC-IM Gasket
LSJ Tensioner Pulley Assembly
LSJ IC Pump Insulator
LSJ IC Pump Rear Bracket
LSJ IC Pump Front Bracket
Heat Exchanger
Heat Exchanger Pump
LSJ Dipstick

And a Tune since you have a 2.2 about your only source for a tune is Trifecta it will run you about $300 with a $200 deductable unless you want to keep the tuning cable that would be 500 total
here is a diagram for limitation on our engines and the parts you need to replace to get to be "safe" at that power level if your really want to make the power without breaking something; build the engine!

 

Very informative! and good luck with the build!

 

The 250 number on the rods is still a debate, although gm stays thats what safe. The destroyed them with a dry shot of nitrous. There are a lot of people around that number with no problems, it all in your tune and how you drive the car to a certain extent (obliviously if you go crazy with the boost you'll blow **** up or bend rods, or destroy pistons)

 

yeah I think the 250 breakpoint is from the instant stress that you get from using NO2, there are people pushing more than 250 with boost on a stock engine you just have to be carefull with the tune and the boost. Personaly I would rather be safe and build it the first time than have to rebuild it after it goes boom

Also the throtle body pigtail will need to be rewired

Damn.. Where can i get these parts? Should i go to a junk yard and have a field day???

Reallly dont want to buy these parts brand new..

 

What throttle body should i get then if I want it to have more flow and be less restrictive?

 

classifieds is your friend

don't need pistons/rods for stage 2 pulley

 

No man? You dont think so? I really dont want to have to go into the motor...

 

The numbers at the top of the chart is HP i take it??

 

Ive read about quite a few 2.2 guys running a stage 2 pulley with no internal work done. I would say you should be fine. But I recommend you search this forum and other delta platform forums for info and parts. There may be some local guys that may be willing to help you out as well!

yessir!

 

Hmm. alright well what is an air box mod? lol your signature. and yes i plan on doing this supercharger and porting it with stage 2 gmpp kit and front mount intercooler.. hopefully the motor holds up.. then beef up the tranny.. Sounds good to me

 

U definitely don't need 60 or 80lb injectors either, the stage 2 injectors from the lsj work great, there 42s

And if u can find an lsj at a scrap yard, strip it, you'll have everything u need

 

Alrighht when i get back from cedar point im going to call around and find a scraped lsj.. and i thought the stage 2 kit is 60 lb injectors..

 

what do you mean by beefing up the tranny? clutch? you will definitely need a clutch. i'm doing a build also, i'm planning on getting a spec stage 2... but i'm contemplating on a spec stage 4 because it's cheaper, just so i'll never have to do a clutch again. and if you port the supercharger, you're going to be getting plenty more power and probably need to do the internals just to be safe... and if you port the supercharger, you might as well port the throttle body too, because that's going to be restricting to it unless it lets in enough air for the ported SC to get it's full potential.

 

Scratch the port part for right now then.. this thing should be plenty fast

 

Hunter I REALLY suggest you start reading some supercharge build threads on here. Specifically mp81, mine, gene culleys. This isn't as simple as you think it is and especially since you didn't know what a heat exchanger was, you have a long way to go.

 

There is a ton of information in the stickys' at the top of the forum (noticed your newer to here). Its not a simple just throw the parts on and damn look at it go. There is some custom work involved in a LSJ take off kit, along with the tuning and data logging to get your car running like it should (boost on our stock tune will destroy everything) If you know how to work on cars then it should be fairly easy, but if you dont know find some people around you that do.

 

That was to the OP right?

 

I say 60 or 80 because I used 42s in my supercharger build and had vac leak issues because 42s are shorter than stockers. so it is true you will most likley not NEED 60s or 80s flow wise but for about the same price why not get 60s which are more capable and are about the same size as stockers. Im just trying to point the guy in the right direction to help him prevent trouble when it comes time for the build

BTW here is a link to a curent ebay listing where you can get some stuf Cobalt SS/Ion Redline Supercharger Kit | eBay
not sure if your ready to get parts or not but just trying to help
And you can get a lot of the little parts off gm parts direct, pm me if you need part numbers I have lots of em

 

haha yea, i was seconding your statement

 

^^This, you really need to know your stuff before you take on this project

 

Its some big stupid plastic air restriction below the airbox that I removed... theres a name for it I just cant think of it. once I removed it it sounded alot better... not sure it really gave me any gains maybe a little better throttle response with my K&n drop in.

 

I had this problem as well

I think the EV1 42's from ZZP are the same length as the 60's though...its the GM stage 2 injectors that are too short

no reason to not run 60's though...if you get ones with the EV6 connectors they plug into the stock harness

 

an airbox mod is going to be the least of your concerns considering you relocate the whole intake setup with a supercharger. and a port and polish would require new rods too most likely. And please define "beef up the tranny", are you auto or manual? Also you need a heat exchanger not an intercooler.
