What pulley were you running when you made those numbers?

This is going to give you vital information on how your engine is doing. It will indicate the air to fuel ratio. It will greatly assist in the tuning process and is needed to make sure your not to lean or to rich for your application.

20 gauge wiring
Zip Ties
Electrical Tape
Plastic Wiring Sleeves


Optional:
LSJ Throttle Body (requires rewiring)
Aero Force Interceptor Gauge
Gauge Pillar
Oil Pressure Gauge

Notes:
• A 2 bar map sensor will work instead of a 2.5 bar map sensor, however the 2.5 bar map sensor from the LSJ will also read intake manifold temps.
• Stock LSJ Injectors will work not work for this setup. The IDC will be too high.
• The stock LSJ belt may also be used with this setup, however it may require a larger idler pulley and there is no guarantee on the fitment of the larger idler on the rebel bracket.
• I’ve heard that the stock LE5 Injector harness will work with the 42.5lb Injectors however I cannot confirm this.

Tool List:
Wrench Set
Spark Plug Socket
Drill with Assorted Bit Sizes.
Soldering Iron (optional)
Screwdrivers
Jack
2x Jack Stands
Creeper (optional)
Grinding Tool
Vice Grips
Box Knife
Teflon Tape
Allen keys

Clearing up some Common Misconceptions:
1. You DO NOT need the LSJ Alternator for this setup, however you will need to cut one rib off the stage two belt
2. You’ll need to rewire the Throttle Body pigtail if you decide to use the LSJ throttle Body. (see below for how to)
3. This is not a BOLT ON, this setup will require a tune, and is unsafe to even attempt to drive if it is not tuned.

Preparation:
1. I highly recommend removing the front bumper, headlights, headlight mounting brackets, front wheels and fender lining, REMOVAL OF THESE ITEMS ARE UP TO YOU TO FIGURE OUT, HOWEVER THEY’RE ALL PRETTY SIMPLE.
2. If you plan on using a LSJ intake you will need to remove the windshield wiper fluid reservoir from the driver’s side fender.
3. You will need to cut open the stock engine wiring harness and relocated the MAF and Throttle Body Wires to the other side of the engine compartment. Allow Plenty of slack in the wiring, they can always be tucked away later.
4. I also would recommend setting up two tables in your workspace. The first with all the items that need to go on the car, and the second for the items you take off the car.
5. Stock the fridge with drinks and snacks, this will take a while!
6. If you are not already using fully synthetic motor oil, you should probably switch over before installing your supercharger. The LE5 requires 5 quarts of 5W-30

Removal of stock components will be up to you (intake/intake manifold/throttle body/etc) if you cannot figure these out you should hire a professional to install this kit.

STEP ONE: Replacing the Spark Plugs
• Using a 10mm Wrench, remove the four bolts securing the coil packs (one bolt for each coil pack)
• Next, remove the coil packs from the valve cover
• Using a spark plug deep socket, an extension and a ratchet, remove one spark plug at a time. After removing one, immediately replace it with the NGK Copper Plugs. Tighten firmly.
• After all four spark plugs have been replaced, reinsert the coil packs into the valve cover and retighten then four 10mm bolts holding them in place.

STEP TWO: Replacing the Injectors
• Using a 10mm Socket, remove the two bolts on the fuel rail.
• Carefully pull up on either end of the fuel rail and wiggle slightly. The Fuel rail along with all four injectors should pop out.
• Remove the wiring harness and the metal clips around the top of each injector
• Lay a towel down over the engine and hold the fuel rail over a small bucket. Wiggle the bottom most injector while pulling and it should pop right out. Let the excess fuel from the fuel rail drain into the bucket.
• Once the fuel rail has drained, remove the rest of the injectors in the same manner as the first.
• Lube the o-rings on the new injectors with motor oil. After oiling, insert one injector at a time into the fuel rail.
• Once all four of the new injectors are in the fuel rail, reinstall the metal securing clips and plug in your new wiring harness to each injector.
• DO NOT reinstall the fuel rail back into the engine at this time, as it will need to come out in order to put the supercharger on the intake manifold, so it is best to just set it aside in the engine compartment.

STEP THREE: Installing the Lower Intake Manifold
• With the stock intake manifold out, cut off the bracket that attaches the dipstick to the old LE5 intake manifold. (This will get in the way of the new intake manifold if not removed)
• Next, you will need to take the lower intake manifold mounting bracket and drill the upper two (non threaded) holes larger (I cannot remember the drill bit size, but the hole needs to be large enough to fit an 8M bolt)
• Once these holes are drilled you will need to bolt the bracket to the engine using the two 8M bolts listed in the parts section.
• Next slide the intake manifold along with its gasket into place. The bottom of the intake manifold should line up with the bracket. Once the intake manifold is properly positioned with its gasket, insert the two 6m studs into the lower middle holes of the flange.



STEP FOUR: Installing and Wiring the Intercooler Pump

Pretty simple. On the front of the block under the intake manifold there will be a few holes that will match up with the mounting bracket. INstall the back side of the bracket first, then place the pump in the bracket, and install the other side of the bracket. Use two butt connectors on the prongs. One of the prongs is labeled positive, the other negative. using the butt connectors, run a wire from the positive to the "fuel pump" fuse and run the negative wire to a ground.

STEP FIVE: Installing and Plumbing the Heat Exchanger
• The intercooler pump 'outlet' needs to be facing upwards. How you route the hoses is up to you, however in order for the system to flow correctly you need to follow the diagram below



STEP SIX: Installing the Idler Assembly

• Simply remove the black bracket on the engine above the alternator by removing the two bolts ( I believe they’re a 14mm bolt)
• Before installing the idler assembly, the idler bracket from rebel autoworx will require some grinding. The inside corner of the bracket by the lower bolt (closest to the pulley) will need some heavy grinding. We had to actually cut the head of the bolt as well to get the belt to slip over the pulley
• Once you have your corners ground down and rounded, you may install the bracket using the stock bolts.



STEP SEVEN: Installing the Blower



STEP EIGHT: Installing the Throttle Body

Four bolts on the S/C housing, pretty self explanitory. Make sure there's a rubber gasket present on the s/c housing side. If you're using the stock tb you may need to drill the bolt holes on the TB a little larger. If using the stock TB make sure its centered on the blower and there are no leaks.

STEP NINE: Wiring the Map Sensor

SEE THE DIAGRAM BELOW: Basically you'll need to cut two wires from the stock MAP sensor (which is located on the fuel injector harness) and splice them into the new map sensor pig tail. Next take two wires from the MAF (see diagram for which to cut) and splice them into the appropriate wires on the new MAP pigtail.



STEP TEN: Bleeding the Heat Exchanger

Find a how to on an aftermarket heat exchanger install for this step lol.

STEP ELEVEN: Connecting Various Vacuum Lines

Attach the valve cover breather to the intake, Brake booster attaches to the throttle body, the other larger hose attaches to the blower housing. The boost bypass valve does not need to be connected to anything other than the one line that runs to the blower housing. Do not plug the other hole on the bypass valve just let it be. Attach the new upper radiator hose and besure the overflow from the engine coolant tank is connected.

Getting your AEM Wideband to work with HP Tuners:

Wiring up the LSJ Throttle Body:



The following wires need to be swapped:
Yellow <--> Brown
Tan <--> Dark Grey
Blue w/ Black Stripe <--> Tan w/ White Stripe

The green and purple wires remain untouched.
There are two tan wires, however if you look closely one has a white stripe its pretty difficult to see.

The larger throttle body needs to be tuned with HPTuners. It threw off my entire A/F by about 1.0 leaner.
Note that I am also throwing the P2101 Code (which is a common code to see after porting a tb etc. This code can be disabled via hpt since it does not affect performance whatsoever)


im doing this setup with a tvs i just bought a lsj alt because i heard it spins another way!

lol, i got the lsj alt too but thats cause the guy threw it in with the kit. guess it puts out more power but i asked hunter awhile ago and he said that my 2.2 alt should still provide enough power for my pioneer setup and crap.

for cleary2.4, i havent finished yet but i'll list some prices
supercharger almost complete kit off CSS.net - 1100 including gas and snacks for the road. (semi local pickup)
TB 6-8 pin adapter - 75
DP - 40
injectors and harness - 100
spark plugs - 25ish
dual pass mod - 80
tune - 250

so idk, 1500+ unless u get the hookup or good deals. thats not including any gauges like intercpeter or wideband.
my parts were on the car for like less than 10k miles so still like brand new.

You have to remove the washer tank from that side. You can either buy an LSJ one (look at the list I gave you in your other thread for the GM part number) or leave it off.

The intake SHOULD clear the brake lines, though.

judging by his thumbnail under his name, its a m62. as for the windshield resivor, you need to get a SS one for the other side. im still looking for one myself T.T was thinking of running like a Short ram intake for the time being. dont think they cost much on gmpartsdirect but the shipping is killer...

cars at the shop right now wish josh or sean would pick upp could there very well be not enough space no matter what i do? I believe the tech said even with the washer tank off it doesnt clear the brake line im going to call in a few and ask them to take a pic and email it to me

The location of the TVS inlet snout should be identical to the M62's. If it wasn't, peoples' throttle body connections and intakes wouldn't fit up. I'm fairly certain that there is just an issue with not having things in the right spot. While my intake does run close to several lines under the hood, it doesn't rub any of them.

i understand that, that makes sense but the TVS is bigger so therefor the inlet snout would be extending further out which in this situation would make the other end stick out more?


also off topic i have a 2.0 mainfold with a 2.0 TB would you say i converted my engine to a smaller 2.0 from a 2.4 thats what my friend keeps saying but i tell him the 2.0 TB is bigger then the 2.4

Honestly, it might be slightly larger, but there is nothing that's anywhere close to the snout on my M62 (and I have an Automatic as well). I need a picture to see what exactly you're talking about... I have a meeting in 10 minutes so I'll be away from my desk for 30 mins or so, FYI.

Also... My oh my... You're still a 2.4 (the displacement of your engine isn't changing at all...) and yes, the LSJ throttle body is larger than the LE5 TB to allow for more air to flow.
