I would like to know for a STOCK ENGINE Cobalt SS Supercharged what is the smallest pulley I could install. Some people said 2.8 others 3.1. I just want to change the pulley nothing else for now. Thank you very much.https://www.cobaltss.net/forums//ima...ies/cssNET.gif

 

u dont want injectors? a 2.8 with stock injectors=fail

 

ummm please move this thread

 

<---- you forgot this ------>

 

lol umm ok

 

its his first post... 2.0 lsj 2.0lnf

easy mistake no need to be cocky

 

CSS.net members are so grumpy

 

cocky? i said please. lol

 

i think he meant the other guy

 

oh lol ok. my bad

 

anyways to the OP anbody on here is going to tell you that once you drop the pulley size that you have to upgrade injectors at a MINIMUM.. cooling mods would be needed for 2.8 and below but people run dual pass's and h/e's on 3" pulleys etc just to be safe

i wasnt trying to be a grump lol i just didnt want this thread to turn into a crap hole... i still suggest he move it but im sure he has no idea what lsj/lnf mean or maybe he does idk

 

no it's cool. well anyway OP congrats on your first post. haha

 

well if he doesn't want to change anything let him not change anything. i wouldn't drop below a 3.1-.2 w/o changing injectors or tune

 

2.0" is the smallest you can run. best if used with stock injectors adds another 95whp and all you have to do is use the GM tune. works great!!

 

youre a sick bastard

 

and this thread is now useless haha

 

a 3in pully is the smallest that you can run on the stock injectors

 

Thank you Guys for all the post. I will install the 3.0 pulley for now. Later on I will install the injectors with a smaller pulley. Thanks.

 

check inbox..... that should steer you in the right direction!!!

 

If you put a 3" on, prepare to go boom. 3" is smaller than the s2 pulley.

 

You can go to a 2.79 pully or you can meachine down the snot and go to 2.50 but that is the smallest I think
