I'm looking to upgrade my 06 cobalt sc to a stage 2.. Can anyone help me on what I need and where to get my stage 2 kit from... All I have done so far is vibrant header and downpipe with vibrant 3" exhaust.. And K&N cold air intake... Please give me some advice on what to do..I'd appreciate it..

 

you looking for more power right the hell with stage 2 go after market there are plenty of people on here parting out there cars you could peace together your own kit thats what i did and find a tuner = way more HP than stage 2

 

Exactly.. So what do I really need??

 

i got a stage 2 pulley that ill sell lol

 

What size and how much?

 

Depends what you're goals are. Do you want something to pep it up a bit or are you looking to put down some good hp?

 

this is the real ?

 

its the GM stage 2 pulley..idk the exact size

 

2.8-2.9 pulley, 80# injectors, a good tune and E-85. Oh, you'll need some cooling mods too!

 

I'm not looking to go to crazy just to pep it up a lil.. I wanna be pushing like close to 300hp

 

thats gonna take alot on stock supercharger lol

 

lol. Thats ONE way to make a grenade...

 

Well I've got vibrant header and 3" exhaust wit k&n already..idk if the makes a difference lol..idk I just want more hp

 

77.9mm = 3.067"

 

whp or bhp??

if whp your best bet (on the m62) would be to convert to E85 and run a 2.7-2.8" pulley, with 80# injectors, a good tune, and full supporting mods.

 

300 motor or whp?

 

What's the difference lol..

 

How does the stock pump like E85?

 

Well 300 motor hp isn't too hard. Buy a ZZP or OTTP stage 2 and you're pretty much there. 300 wheel hp will require alot more modding. If you're looking to do 300 wheel hp talk to ebristol and his mods.

 

Ok which one would u prefer zzp or ottp? And around how much more hp will I be looking at with headers and 3" exhaust and intake

 

Alright which one would u prefer the zzp or ottp? And around how much hp will I be looking at with a good tune? And I already have header and 3" exhaust with a cold air intaake

 

I like ZZP.

 

Both are good. If you're getting a custom tune it doesnt really matter who you go with. You'll be in the 260whp range

 

bhp is measured at the crank.

whp is measured at the wheels.

whp is the hp that counts.

 

But you have a 3" exhaust! You might as well support that mod.
