This thread is intended to organize all the information that's floating around the 2.0L Technical section about the GM staged Kits.

Please only post FAQs (conclusive information) about the kits. Provide supportive material and documentation if you can for each bit of information you contrubite.

-Stage two – 3” Pulley smaller belt & everything in Stage 1



-Both kits contain the same ECM Re-flash

- No Badging is included in the kit
- Instructions are provided




- You may have the install done from an outside shop and flashed with the author code by GM (warranty may not apply if installed by an outside shop – if part failure is found to be a direct result of how the parts were installed)

-Stage 2 Kit has been Proven to get rid of lean CEL

-Cost varies dealer to dealer however install time should be roughly 1.5 hours


-Stage Redline is adjusted to 7000 RPM

The lean code P0171 hasn't popped up yet so we'll see.
The redline in the first 3 gears is 7000 RPM as I still have my winter tires on and haven't got that high yet
The stumbling idle when blipping the throttle at a stop is gone.
The idle is raised slightly to about 875 RPM.
Car feels more tuned but still has the feel that we fell in love with.
Will bring lots of smiles

First gear has been proven already with a Tech2 scan.

2nd/3rd/4th/5th gears have not. Can someone please verify this also with a tech2?

I was told otherwise and that 1st gear was only changed due to less engine load.

VictoryRed06

im gonna say its fun all the way around..i saw on another thread that when in low rpm and u step on it..boost automatically goes to 12.5 and higher rpm goes to like 15/16...i cant wait for mine!!

MarcS

Trying to help you guys out here. Lets stick to just submitting information

Example:

Q: What is the pulley size for stage 2?
A: 3"

jlewis2578

Is the reflash available with out purchasing the entire kit. I'm sure alot of us have already changed out the pulley and the injectors. If so how do we go about doing it?

selfinfliction

only way it will work is if you keep the thread locked and have people submit the Q&A's through pm's to you. all threads go off topic by the 2-3 page

MarcS

Yeah, I think you're right.

c7015

Me Too ...


also Mark I have added links for images ....so if you want to update the first post I have PM'd you the info

SS_SC_Cobalt

ok I'll add to the faq:

Q:Is the reflash available without getting the stage kits?
A: NO, an authorization number is on the instruction manual that is needed by the GM tech doing the reflash to allow him to get the proper reflash part number loaded into the tech 2.
Available flash part numbers are:
12607644 05 Cobalt SS
12607645 06 Cobalt SS
12607646 04 Ion RL
12607647 05 Ion RL
12607648 06 Ion RL

With the 3.0 pulley (GM) can we go smaller than that, without changing the hub or snout?

c7015

If you want to add this info too

Q. What are the Injector Sizes
A. The injectors are 5.3 gms/sec flow. (Roughly 42 lbs/hr)

Q.How much bigger are the injectors
A.The stock injectors are 4.3 gms/sec. . Stock injectors are about 34 lbs/hr

Q. How will Stage kits effect fuel economy
A. We dont know conclusivly however it is safe to assume that the larger injectors will decrease MPG slightly the rest is up to the driver

SS_SC_Cobalt

A:Yes the Stage 2 Kit pulley is a modular design that is held on with 4 bolts. At this time it is not proven if a current aftermarket pulley will bolt to the stock GM Kit Hub.

retrop

A(cont): If some-one starts to make 4 bolt pulleys for the hub. Looking at other designs (ZZP and Billetflow which are both 5 bolt) it is not possible to re-use the hub YET.

SS_SC_Cobalt

Dub is a 4 bolt pulley but not proven if it will fit. GM is spposedly making other pulleys according to a gm poster that was shown, but no size announcements yet.

philco_3

Here are a couple of questions I have...

1)How long did the dealer work on your upgrade. (My dealership is saying something like over 4 hrs for the stage 2, which I dont think is right)

2)What kinda of MPG are you guys looking at currently at with the stage 2 upgrade.

Zenkat

If you have your dealer's parts department call the PARTEC hotline, they'll find the listed time for Stage 1 is 1.0 hours, and Stage 2 is 1.5 hours.

If the dealer is doing this for the first time, you may have to work with them on it.

Stage 2 Individeal Part Numbers

Smaller Belt: 12597993
High Flow Injectors 12597995

These numbers do not show up on gmpartsdirect.com. The Hub assembly does not have any parts numbers on it.

TheToolmaker

Dealer install on stage 2 appears to be between 2.5-3 hours. It takes awhile on the phone to get the VCI or whatever its called. Mine took 3 hours (tech took it for a drive in that time too).

I have put ~250 miles on my stage 2 kit. The whole tank of gas I averaged 23 mpg. When I reset it on the highway I was getting ~30mpg and of course I have put the hammer down in that time too.......

KangolRiot

with Stage 2.. if we went down to a smaller pulley (such as 2.9 for ex.) would we still have to run the boost bypass mod?

kissmySS

I believe that is correct....but i could be wrong....!

Yea, the recently published PARTEC time for Stage 2 is rediculous. The prima donna front line drivability techs that are best suited and trained to do this type of work will just refuse to do it for 1.5 (since the warranty flat-rate for the same operations is more than DOUBLE that) So then the job will just end up getting dispatched to a back-shop "Bubba" that's never opened the hood on an LSJ- So he CANT WAIT to do a Before/After roadtest your prize ride and very likely get axle grease all over your seats and doors! Whoever developed the op-time for the Stage 2 messed up IMO- THIS ISNT A SET OF RUNNING BOARDS! All it does is promote the tech to RUSH through the installation and potentially make mistakes and/or cause damage.

The injectors seem like they arnt a big deal if you just count the fasteners, BUT you DO need to do a few additional steps to do it safely (battery disconnect) and keep from leaking fuel all over your engine and wiring harnesses. Then a reflash typically takes .4-.5 at the best of times but it's taking a LOT longer on the Stage kits as you gotta phone 1-800-Techline (and usually wait on hold for 10) just to get the VCI code to install the software. Then afterwards you need to warm the engine to operating temperature, do a crankshaft variation relearn and road test to get the fuel trims moving in the right direction (they get reset during a reflash)

The pulley is totally a hit and miss. Maybe if GMPP would have issued a proper puller/installer to the dealers that could eliminate having to pull the supercharger, the 1.5 time allowance would be more realistic. (trust me they dont have one) So instead they are being advised to remove the supercharger completly and "rig" something up on the grubby old 20-ton press to remove and install the pulley.I can forsee all sorts of pulley damage and various pulley/sc problems at some dealers. I've also heard of at least one case of the SC bolts being stripped out from over-tightening with an air tool (again all because at that point the techncian is taking shortcuts as he's working on his own time for free at that point)

Total BS! Partec reps are gonna get an earful!!

EDIT>OOPS Sorry Marc, just realized this was an FAQ thread. Feel free to move my post- Wop

CobaltSS422

Shouldn't the Chevy dealers have one? What if someone brought in their Supercharged Monte Carlo SS 3800 Series V-6?

WopOnTour

The supercharger pulleys ARE NOT servicable under "regular" GM service practises. So NO there isnt one as part of their regular tool inventory.
