Official GM Supercharger Pre 00 Information Sticky
Thursday, March 09, 2006 2:40 PM
The GM Supercharger sticky is here! Please people read this before putting up another post in which there is already 100’s of.


Before I start with the information, If anyone would like to add their part please do so!
First of all, the gm s/c was designed by GM for 2000+ j-bodies…..Over the years many of us have installed this unit onto our Pre 99 cars.

What you will see below is the list and needed mods that I know of (To the best of my ability). Again if I leave anything out please put it in here. I am only putting this up to help people that can’t find their answers.

General installation time has been from 3.5 hours to 9 hours, depending on your speed and knowledge of what your doing.

If you are wanting to get part #’s for certain parts here is a link-

After clicking, wait for the little box at the bottom right so u can zoom in!


Spark plugs
1 step colder that come with the kit- Part# 05613717
2 step colder plugs that some(Including myself)are using-Part #5614285

Both plugs are AC Delco plugs in case anyone wonders.




Ok so you have a 1999 Cavalier/Sunfire and you want to buy a supercharger kit. Great, Now what do you need you ask? Well here’s a list of things………

1. You need the s/c kit obviously J

2. Most of the 1999 cars were equipped with high impedance(skinny) injectors, no egr, and already have the smaller 2000+ starter. Therefore your install is going to be easier than a pre 98 car.

3. The only things you will not be able to use in the kit is the 2 bar map sensor, and get the computer reflash. Just resell the map and you’ll make some money back J


4. Since the computer will not be able to read the boost(You wont have the reflash), You will need a afpr to adjust your base idle pressure because of the larger injectors, and some sort of fuel management (i.e.- Cartech fmu, emanage, etc)

5. Having some type of Wideband o2 sensor will help you in your tuning process also. This will aid in knowing if you are running rich/lean.



So you want to install the s/c kit on your 98 Pre Cavalier/Sunfire. Well here’s a list of things you will need to do/buy. Again if I have missed anything please add to this post.

Well now you guys have a little more work to do than the 1999 guys so here it is:

You will need to go buy:

1. Starter from a 2000+ car(Smaller starter)
2. Egr block off plate (Jake aka GreenZ would be able to help as far as egr goes)
3. Your injectors are LOW IMPEDANCE(Fat ones), therefore you CAN’T use the injectors that come with the supercharger kit. So you will either be able to use your stock injectors, or you can buy bigger ones from RC Engineering.
4. Along with the 99 cars, your computer will NOT be able to read boost, so you will need some “fuel tuning devices” such as:
a. FMU(To raise the fuel pressure as you get into boost)
b. AFPR (To adjust the base idle pressure if you buy bigger injectors)
c. Bigger injectors would be recommended(Some guys have been using stock injectors w/ an fmu and bigger fuel pump and have had no problems-(Jake/GreenZ)
d. I would also suggest upgrading your fuel pump to a Walbro 255lph pump.

5. I would also strongly recommend buying some type of wideband o2 so you can see exactly how rich/lean you are running since you will not be using the reflash.

6. Like the 99 guys, You will be able to resell the map sensor and injectors and make some money back.



Basically what I wanted to do here was give a “General” overview of what is needed and how to’s on this supercharger kit. Once again if anyone has anything to add PLEASE DO SO!

here is my set up and i suggest others to follow it. (i am on the stock s/c pulley)
2k starter
stock injectors, fpr
cartech FMU
walbro 255 fuel pump
coolingmist.com water/meth injection (m4 injector)
ac delco # 41-602

for the egr i got the GM block off plate and just removed all of the EGR stuff.
I clear the check engine light each time i start my car with a code scanner. IT takes 30 seconds to do and my car runs like stock and gets like 30miles per gallon. With the EGR simulator hooked up, my car ran like crap and randomly stalled and hesitated alot. SO i just ditched that. sorta a pain, but the way the car runs it makes it worth the little bit of hassle.

need anything else answered just ask away

There was a good link in this forum posted a while back that was similar to the link above but had a details of a 1999 2.4 installation of the gm supercharger. Anyone remember where that web page is? It would be a good fit for this thread. I wish I saved it myself.

Very good information...however I did it a little differently....

I have a supercharged 99 automatic

First off,
I had the correct starter (00+)
I didnt have an EGR
I had the high impedance(skinny) injectors already

However,
I am using the 2 bar map sensor, because im using a 2000+ automatic PCM with the reflash already installed onto the PCM.

Currently seeing 6psi of boost.

I would like to add for us 1998 and lower guys I would say a Cartech FMU or other is almost 100% necessary. The problem with just running bigger injectors and an adjustable fuel pressure regulator is that you do not get added fuel while in full boost. I made this mistake and leaned it out and spun a bearing.

I was running GM SC, 320 cc RC injectors and the LT1 AFPR.

Also the Starter is 89.99 plus core at autozone and you do need it.

A few things you can make if you buy a second hand kit thats missin things are...

Cruise bracket, can be made easily and you dont have to pay extra for it if your missing it. Email me for more details.

Brake booster line, you can modify your stock one and it will work fine, just need a little cutting.

Like everyone else said, just sell the 2 bar censor to a turbo guy or something.

Make sure everyone checks their plugs and get some kind of fuel compensation for boost!

You will injoy this mod, I would say its worth every penny.

Does anyone have a .pdf of the installation instructions for the kit? or maybe someone could scan them in? is there any posts with a step by step how-to? that would be a useful link for this thread. Just seems like there are a lot of parts in the kit... it would be nice to know where they all go... thanks,
Matt

would getting a 99 ECU be worth it for us 96-98 guys, or would the new HP Tuners kit be better later down the road?


Re: Official GM Supercharger Pre 00 Information St
Wednesday, March 29, 2006 9:02 AM
97-98 you can re wire it to a 99 ecu fairly easy(search).

96(like me) would have to cut off the 96 harness and re pin it to a 99, get a99 computer(or a 97/98 and flash it with a VIN from 99 5 spd) and use the HP software(currently contemplating going that route).






Re: Official GM Supercharger Pre 00 Information St

that makes things sound good, i wouldnt mind paying for a flash (providing i can get a VIN), and using HP tuners that way. That would mean no EGR codes, and the skinny injectors (high impedence).

mm.. so is it safe to say if you were s/cing a 99 cavy and had hpt and then use bigger injector, you wouldn't need an AFPR?
