poeple i need your help.

i am from mexico and i want to SC my G5 GT 2.4L.....

my question is that i am going to buy the SC kit from the cobalt SC, the M62, intake manifold, injectors, etc..... the whole kit..


so at how many PSI can i set my g5 without blow my engine LOL..... or can i have the stage 2 configuration with out blowing it up?

 

Stage 2 pulley is relatively safe on the 2.4. I wouldn't/am not going to go any smaller without cooling mods, though.

 

stage 2 you should be fine with, you will have to start worrying when you get near 275-300whp

 

Where are you buying the parts from? Is this an actual kit your purchasing or are you putting the parts together?

 

i am looking for some info first,

i am gonna buy thing by thing.... the problem is than in mexico whe dont have cobalt so i´ll need to buy everything ovether in your country LOL.... probably i´ll buy the M62 and the intake in a junk yard, or i´ll probablybuy the thing from a member of this forum....



so any way, i am really safe with the stage 2 pulley?

so i´ll need

- eaton m62
-lsj intake manifold
- stage 2 pulley, injectors, and belt
- heat exchanger and pump
- psi gauge
- hp tunner

what else??????? or thats it?

 

hptuners doesnt work with your car...

 

I'm running a 2.9 pulley which is slightly smaller. I haven't gotten a tune since I switched from the stage 2 and it has been fine.

 

what kind of tunned do you have?

 

I am running 2.9 pulley on 2009 G5. I was running 285 crank hp before I changed MAP sensors... still in the tuning stage with it.

Here is my recent and last supercharging list. It doesn't get any more detailed than this.

This list is broken down to bare essentials for supercharging only and then adds the optional exhaust and optional wiper conversion lists. What type of injectors, pulley’s and other items you choose to change are strictly up to you. This is the list that I used and have modified it for a universal parts list.

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.

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.

 

^^^^^ now thats a person who knows how to help out on a forum

and did anyone mention ls1 edit for tuning

 

thanks man.............. now i really have an idea... it will be w really big proyect for me =)

but what about the computer?

how much have you spend untill today? and whats your time in 1/4?

please let me see some pics of your engine =)

 

Hey gene, I'm using the stock brake booster cable. I saw that you are using the lsj one. The only reason you did that was so it fits better and looks stock right? Or is there any mechanical/performance reasoning behind that.

The reason I ask is because I have a bogging issue when launching, and my tuner said that the computer isn't allowing my tb to open all the way when I floor it. I was thinking maybe the brake booster cable might have something to do with it for some reason.

 

I'm selling my whole setup if someone gives me what it's worth. One source, all the parts, 1 shipping price. Think about it...

 

i have alot of random parts for sale, that are hard to come by, check my for sale thread

 

Thanks. I did it for everyone since I got a lot of help during my install from many people on the board. Only trying to give back.

Vince tunes the car via the internet. (Trifecta Performance).

I spent 3G, but I got more new stuff and more detailed parts that necessary and powerdcoated some stuff.



I got it so it would look factory like the LSJ. I don't quite think the computer wouldn't let the throttle body open all of the way. That is quite odd. Sounds like a tuning issue to me.

 

sounds like traction control to me. You wont want to go WOT from a stop anyways....you'll just spin

 

I'm giving you a virtual high five for having a sick engine bay.

What kind of numbers are you pulling? Any idea?

 

My traction control is off when I launch from "L" and I'm not saying I would want to go wot, but it doesn't let me anyways. BOGGING sucks!

 

I get the same deal...but it feels EXACTLY like traction control. I'm thinking maybe its a transmission abuse mode activating or something else similar.

 

i hopefully will be able to put this together around christmas time. im gonna start saving now
