Hey guy i have a 2012 ls7 that i want to install in my 2006 ls2 c6 track car..

I am looking for any info on what it would take to do that..

Thanks..

Manny

 

Are you converting it to wet sump?

 

If you convert the LS7 to a wet sump engine its a direct bolt in. If you keep the dry sump system then the only real headache is moving the battery to the rear compartment and fitting in all the cabling. Even then its not that big of a deal other than time and money. Installing the factory dry sump tank and lines is a fairly easy thing to do as it will just bolt in. However there are no bolt holes in the frame for the lower tank mount so those will have to be added. All the battery cables are available from GM as are all the tank parts. You can even use the existing engine wiring harness as all the sensors and connections are the same as your LS2.

 

I've done it a few times. While I currently don't have a write up, I can answer any specific questions you might have.

No i want the dry sump set up maybe even change to a 4stage setup

 

cool so i can us my 06 harness for a 2012 ls7?
Would i have to change the ecu and get it re flashed

 

I have a set of factory cables to move the battery to the trunk if you are interested. They have never been installed.

 

Hey Christopher .. i have now a ls2 c6 the motor i have coming is a 2012 ls7 is there any harness that i will need to replace? this is for a track only car that we run in many events..

 

You won't need a completely new wiring harness but you will need a couple different connectors to make it work.

If you're gonna run an LS7 MAF then you'll need to cut off your stock connector and replace it with one from a Z06. Fortunately the color coding of the wires is the same so it's easy to hook up. The same goes for your cam sensor connector as it's also a different connector but with the same wires.

On the LS2 there is one connector that plugs into the oil pan and is used for both the low oil level indicator and oil temp. That connector doesn't exist on an LS7 but there is one for the oil temperature which connects to the oil tank. With that one you'll need to wire the oil tank connector into the correct pins on the LS2 connector which I can help you with as you get closer. There isn't a low oil level indicator on the LS7 however.

You'll also need to run at least stock LS7 injectors as the LS2 injectors won't provide it with enough fuel.

As for the PCM, it's basically a process of fooling your PCM into thinking it's just a larger displacement LS2 which can be done using HP Tuners or EFI Live. That part takes all of about 15 minutes.

There are some differences with the wires going into the starter but I'd have to talk to my local parts guy to get you the particulars on that.

Hope that helps.

 

Great help the info you have given me is great and get me going down the right path.. i will be running the LS7 stock injectors that cam with the motor,,,I would like to get us the LS2 ECM and i have a buddy that works on programming them for Mousler cars.. he uses hp tuner i will give him a call to see if he can reprogram ,,,

really look like it may be easier than i thought.. I really appreciate the info and please keep me post if you think of anything else,,, one more quick question what about the reluctor wheel i believe the ls2 is different than the ls7 ?

thanks in advance ,,,Manny

 

You won't have to worry about the reluctor wheel if the car's a 2006. With 2005 and earlier cars it was a 24 tooth but everything's a 58 tooth for anything newer than that.

The one thing that you probably will hate doing though it cutting out the battery tray to make room for the oil tank. Part of it unbolts but there's a sizeable piece that needs to be cut from the frame and it is a major PITA.

 

Manny, I converted my 05 LS2 car to a dry sump LS3. Yours should be easier since you already have a computer looking for a 58 tooth relict or wheel (no conversion harness/box). I will get in touch with you this week to let you know what it takes. Not too bad of a job.

Start with this but ignore any reference to the Lingenfelter conversion box.

He did a really nice job documenting how to do. It should save you a ton of time.

 

Also the 2012 oil pressure sensor and possibly the 2012 MAP sensor is different. All you need to do is to swap them out with your stock sensors from the LS2. You can delete the oil level sensor from the LS2, and you can wire in the oil temp sensor that will be relocated to the dry sump tank. Also the LS7 MAF is different but all you need is the LS7 MAF sensor pig tail and wire in the LS7 MAF to your existing harness, even the color codes are the same. The LS7 injectors should connect to the existing LS2 injector connectors, they should be the same USCAR connectors.
