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
GlowShift Vacuum | Boost Gauge
AEM Wideband Air | Fuel Ratio Gauge
OTTP 2.9 Polished Pulley (For Stage 2 Hub)
M-8501-L54 Ford Racing Intercooler Pump
NGK Copper Spark Plugs (Part# LFR6A-11) (Also one step colder)

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

Stock LSJ Alternator Bracket

Optional Parts

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.

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.

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

Hose routing is with using ZZP heat exchanger only with 10 feet of ž 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.

Exhaust Parts (Optional)

GM Parts

90537953 – LSJ Exhaust Manifold Heat Shield
15231157 – LSJ Downpipe To Cat Back Gasket
15235773 – LSJ Exhaust Manifold To Downpipe Gasket

Use your stock 2.2 or 2.4 exhaust manifold gasket, or buy new, as if you used the LSJ exhaust manifold gasket it wouldn’t fit properly and you would have an exhaust leak and/or noise.

Used Parts

Stock LSJ Downpipe
Stock LSJ Exhaust Manifold

The stock LSJ downpipe works on any manual shift car. It does not fit the automatic because of the way the automatic engine sits in the vehicle.

The LSJ exhaust manifold and LSJ downpipe are much bigger to allow more exhaust to exit the engine. This is important as you are forcing more air into the engine with the supercharger so you need to provide adequate output as well. Feel free to purchase your aftermarket selection of header/dp combo.

Windshield Wiper Conversion (Optional)

GM Parts

22729469 – LSJ Windshield Washer Container
22732432 – LSJ Wiper Cowl To Washer Container Hose

You’re moving the LSJ air intake to the left side of the vehicle and that is where the 2.2 and 2.4 windshield wiper container is. The container I listed includes a new pump, grommet, cap and hose to attach to wiper cowl hose. The wiper cowl to container hose I list is the original GM hose on the LSJ that goes from the left side of the wiper cowl (where ours is) and takes it to the right side where it meets up with the LSJ washer container that I list. As far as the connector for the pump, I cut the end of the connector off and added new wire to loom it from the left side of the car to the right side of the car to the new container location. I ran the loom across the top of the inside of the radiator support where there is already a loom running for something else. I ran it inside its own loom and wire tired to the existing loom.

Bad idea? Anyone here running a zzp kit? Also, my balt is an 06 so, I've got an 8 pin tb connector? So, no problems?
If anyone has any of the aforementioned brackets, or any parts that I need for that matter, I'm interested.
