That looks like a 2.9 nate pulley to me, its hard to tell because the side ridges are much larger on the S2. Only way to really tell is to calculate out the diameter differences from measuring the circumfrences or using a fat micrometer.

 

i ordered it from nate and i got the pulley and bolts...but cars kinda down now,so it doesnt really matter anymore

 

please tell me your not rockin the NGK spark plugs.... also, I really won't recommend using a 2.9 on Stage 2. I know most people with disagree but I've not run across anyone who has it on there for more then half a year without taking it off. Check your SIP sensor on the blower, something tells me it could be off.

 

I have the NGK Copper One's not iridruim(spelling)..had dealer check everything and they didnt find jack...only other thing left to do was change the pulley back to a s2 pulley,and i did that earlyier today and passed 150 miles and still no check engine light...i got it out of dealer and passed 75 miles and it turned on

 

dude get the dam reflash from gm its not the "latest update for s2" its a different reflash i had the same codes over and over again and found out from the dealership that WE HAVE 7 UPGRADES that the only way to fix it so go there and ask them to put ur car on there tech 2 tool

 

they did...i saw them using the tech 2 tool whole time i was there,they told me i have the lastest s2 reflash

 

****, i have one of the first S2 tunes on the market and i'm still running good (never reflashed) running 2.9" and NGK copper 1 steppers. Only p0171 code was from a stock folded coupler on my intake tubing on the underside where i couldn't see for months after doing my airbox mod. I was going crazy til i switched to an ebay CAI and found the problem.

oh yeah, and it ran like a bitch with that code, i bought a scan gauge because of it.

 

something isn't adding up the s2 reflash isn't the same the s2 reflash u had to buy in a kit the reflash im talking about is from gm to fix the little problems our cars have sorry but there wrong

 

i pulled these two codes too... but i am a stock 2.2L

well atleast stock as in no power adders (intake, exhaust, turbo, s/c, none of that)

the codes been on for months and i havent found a way to get rid of them. need emissions test this thursday and need help!!!

 

i had them deleted...had a buddy delete the code with hp tuners,and im all good now..only reason i have been poppin that code is cuz the MAF isnt reading the right amount of air,and it gets worried and pops the light...

just go to dealer and tell them to erase the code and it will never come back again

 

so i can get both or just the p0300 cleared?

 

the p0300 is a spark plug problem..do to the dealer and get some stock plugs,and the p0171 is a problem the dealer will take cpl of months to fix,and eventually will never fix it..just request to get them bother deleted,but ur responsible if anything happens after that...

 

thanks man, info helped a lot. hopefully it doesnt come back when i go for emissioins testing thursday

 

I don't think that you're aware of how the pulley size is measured, measure the total diameter, then measure the distance from the outside ridge to the top of the ribs on the pulley.

Lets say the total diameter is D and the distance from the outside ridge to the top of the ribs where the belt rides is S

D - 2*S = pulley size, which I assure you is 2.9 in your case.

if i put stock ss/sc injectors in... the 32lb ones would i run richer or leaner???

and would that maybe help my p0171 code... i just failed the ****** retest again but i got the inspection passsed so now i got 20 days for this and p0300 code to clear but im pretty sure 0300 is gone

help???
