Purchasing the LSJ power brake booster hose takes care of 2 issues. I cut off the ends of my 2.2 hose and used it as a PCV hose from the valve cover to the LSJ air intake hose. It gives you the correct hose from your power brake booster to SC and gives you a factory looking formed hose for your PCV hose.

New Non- GM Parts

ZZP Heat Exchanger have a cobra h/e
GlowShift Vacuum | Boost Gauge ordered
AEM Wideband Air | Fuel Ratio Gauge have innovate lc-1
OTTP 2.9 Polished Pulley (For Stage 2 Hub) bought a gm stage 2 pulley
M-8501-L54 Ford Racing Intercooler Pump using stock h/e pump
NGK Copper Spark Plugs (Part# LFR6A-11) (Also one step colder) still need

Copper plugs are better than Iridium plugs or any other plugs for supercharged applications. People have gaps anywhere from .035 to .040. They come .040 and that is what I am using.

Used Parts

Eaton M62 Supercharger coming in the kit
GM Stage 2 Injectors (42lbs) getting 60's with my kit
Stock LSJ Air Intake coming in the kit
Stock LSJ Tensioner coming in the kit
Stock LSJ Idler Pulley coming in the kit
Stock LSJ Throttle Body ordered
Stock LSJ Intake Manifold coming in the kit
Stock LSJ Alternator Bracket coming in the kit

Optional Parts

ZZP Triple Gauge Pod ordered a dual
Aeroforce Interceptor Gauge

Injector Harness

I used the 2005 Cavalier injector wiring harness because it came with the proper connectors for using the original GM 42.5 lb Stage 2 injectors. I did have to splice my MAP sensor connector in from my original harness as I started out with the stock MAP sensor.

MAP Sensor

You can choose to use 3 different MAP sensors for your conversion. Which MAP sensor you choose will also depend on the connector needed to be used.

Stock MAP
This MAP sensor fits into the LSJ intake manifold, but you must modify the opening in the sensor where it screws into the intake. How I modified the sensor is in my SC build thread. This is the least expensive option and is the least hassle option.

LSJ 1 Bar MAP
This is the MAP sensor that is used in the SC on the stock LSJ. We can take that sensor and use it in the LSJ intake manifold. You will need to modify a means to secure it and also seal it to the LSJ intake manifold. How I modified this sensor to fit my car is also in my SC build thread. I would honestly say this is the least optimal choice out of the 3 possibilities for me.

LSJ 2.5 Bar MAP
This is the real MAP sensor used on the stock LSJ in the intake manifold. It best fits the stock LSJ intake manifold (obviously). This MAP sensor also has a temp sensor, otherwise known as IAT2 (Intake Air Temperature 2). Our cars cannot read the temp without modification. How I did the 2.5 bar MAP sensor conversion to read IAT2’s is also in my SC build thread.


still undecided what to do about a map sensor. suggestions?

Throttle Body Connector

If you are using the LSJ throttle body the connector you’ll need to have is an 8 pin. Regardless of what connector you do have or if you have to purchase the 8 pin, you will need to wire them for the LSJ TB.

2005 – 2006 2.2’s have an 8 pin connector. No new connector is needed.
2007+ 2.2’s have a 6 pin connector and you will need the 8 pin connector.

2006 – 2007 2.4’s have an 8 pin connector. No new connector is needed.
2008+ 2.4’s have a 6 pin connector and you will need the 8 pin connector.

If you need the 8 pin connector you’ll need the one below.

88986255 – LSJ 8 Pin TB Connector ordered

Supercharger Cooling System

New GM Parts

22697069 – LSC SC Coolant Reservoir
15076936 – LSJ SC Coolant Reservoir Cap
15271970 – LSJ SC Coolant Reservoir Bracket
22697111 – LSJ SC Coolant Reservoir Overflow Hose
22699879 – LSJ SC Coolant Reservoir Inlet To Top Intake Manifold End Plate Hose
22707607 – LSJ Bottom Intake Manifold End Plate To Intercooler Pump Outlet Hose

using a stock filler neck, and im gonna use universal hoses to save some cash

Hose routing is with using ZZP heat exchanger only with 10 feet of ¾ heater hose. The house routing diagram I used is in my SC build thread.

First hose went from LSJ SC coolant reservoir outlet to ZZP heat exchanger inlet.
Second hose went from intercooler pump inlet to ZZP heat exchanger outlet.

I chose the stock SC cooling system for now. If you choose to use option B or any other alternative then you will need different hoses and lengths of hose.

I am running a 2.9 pulley with the ZZP heat exchanger only and my IAT2 temps are within +20 to +30 above ambient temp (which is optimal). Of course in traffic or during heavy WOT runs the temps are higher as expected (which is normal). This cooling method is very adequate.

End of bare essentials list to supercharge your 2.2 or 2.4. The rest of the list below is simply optional.

nicce bro ill be following :) Sedans FTW!!!

hell yeah, nothing better than a whining sedan to shut people up haha

or a sneezing sedan haha

I disagree with the plugs tho. I use NHL iridiums bkr7eix on my ss/sc and their gapped at .032. Coppers didnt run as well or last as long.

Ngk** lol. Good luck tho. Sound like fun.

ill check em out

i had the NGK BRK7E's on my modded ss/sc and they were good for me

and im putting this here so i dont lose it, this is the diagram im gonna use to wire my tb in

http://i439.photobucket.com/albums/q...ireHarness.jpg

just as a warning i know on my build with that diagram i had to swap the yellow and brown wires with each other, if you need any help at all let me know my build is still fresh in my mind

thanks man, ill make a note of that

and a question for ya, i entered in the part number for the lsj tb harness and its like 80 bucks on gmpartsdirect? is that right? seems like way too much..

Subd. :)

i didnt get mine brand new but i paid 30 bucks for one off some guy on yourcobalt and i think the dealer quoted me around 100 i think

mine luckily came with the blower.Mine was all off a junkyard car with 15k miles.Got the blower,intake manifold,TB,intercooler pump,tensioner,idler pulley,and other various parts for $300.Steal of a lifetime :D.

I paid 450 for mine, and its coming with the blower, LIM, h/e pump, stage 2 belt, 2 sets of injectors, an injector harness, idler pulley, tensioner, and all the brackets im gonna need

booooooost is the best thing bro

Good deal man.Your gonna love it!I'd help if you lived remotely close to me lmao

i know, i cant wait. just a couple hundred more in parts and im ready. this thing is a money pit already, so far ive spent 850 and im not done yet haha. and then top top it off i need to pay 200 for a tune. i wish vince would retune me for free haha

lol i wish everything was free.....

Me too.Im going HPT soon.My Trifukta tune suxass.8* of KR yet Vince says everythings good :lol:.

boost is a wonderful thing i thought about doing sc but i found some old thread on the cobalt using a procharger instead im working on getting the money for that atm its alot more pricy because prochargers do not come cheap

I wanna swap the ol heaton for a procharger.Would be awesome

yea I would perfer hp tuners but I dont know jack about tuning. Vince is ok tho

I'll keep my mouth closed lmao.I'm having a local tune it for me.He tuned his own twicharged setup and tuned my buddys E85 turbo 2.2.Both are stupid fast.
