Just wondering if there is a way to check if i have a stock ss/sc or a stage kit has been installed? i bought it used so i don't know what the guy before me did to it...
any help is welcomed and one more thing, how much psi/kpa would a non-modded sc make vs a modded one?

 

look at the pulley itself on the supercharger for numbers like 77.9mm or 2.9. How much you boosting as well might be a indicator a pulley been changed. Stage two is usually around 15psi while stock i believe is around 12.

I bought my car and was about to buy a gm stage kit until i found out it was already stage 2.

 

Thats exactly what i want to avoid

 

Why would you want to avoid this. Saved me $1000 right out of the gate.

 

I meant i want to avoid buying a stage 2 kit only to find out I got it already

 

yup just check the pulley or take a pic of it and post it for us. We will tell you what you got.

 

Does the supercharger pulley have any bolts ? or it a round black pulley with one hole in the middle ? look at ur fuel injectors do they have a blue ring on top or green ?!

 

its the black one with a hole in the middle

you are on stock pulley so no gm stage 2 how about injectors ?

 

Look underneath the fuel rail, if the injectors are GREEN you are stock, if they are black you are stage 1.

 

they are green...guess its stock

 

so u officially have no stage kit !

Go get one now lol

 

i can just get stage two right? skip stage one since two has everything that stage one has? which website should i order from? zzperformance, crateenginedepot or just go to the dealer?

 

Yes you can just go to a stage 2. If you have any warranty and want to keep it go with crateenginedepot. If not i suggest ZZP or OTTP. DON'T go to a dealer.

 

Would I need to get a cai and change the exhaust cuz they still stock as well

 

no you don't need to, but depending on which stage kit you wanna go with and depending on your power goals an exhaust system upgrade might be neccessary or is recommended

 

Lets say i want to go with stage 2 n i want to avg 250hp... Wot wud you suggest? I ws tinkin more aling da lines of an injen intake, gmpp exhaust..

 

Take a look at my mods...

 

Where would you recommend for installation in the Peg? Motion performance car tuning on king edward?

 

You're stage 2? I can help you out if you want

 

Nope, still stock apparently. Itd b great if u cud. Inbox me your number and il get in touch

 

I will sell you my GM Stage 2 parts dirt cheap. Taking them off the car this week and going 2.8 and 60's. Just a offer pm me if intersted.

 

assuming your getting GM stage 2 I'd pick the dealer over crate, crate is cheaper, but I just prefer knowing that if something ***** up its all on the dealer no "Oh well you bought it from blah blah" and so on

But if you have a good mechanic/performance guy you go to I would get the ZZP or OTTP one, cheaper and faster


But...


GM stage 2 is the slowest stage kit upgrade, but you'll still be grinning like a ************ when you first floor it

 

I did not find it slow at all since i was able to run better times than people with more mods and some with slicks even. With just a GM2 and CAI i was able to pull 13.6 runs at the track. Dont consider it super fast but definately not slow. Also put down 244/225 with GM2,CAI, 2.9 pulley.

 

No, really its not.
