Ive been told a lo of CTS-V guys have done Maggie 112 conversions, meaning they've converted a Maggie designed for a L2/ LS7 to work on a LS1/ LS6. Im about to do the same. Original unit is off an LS2 GTO, and is going on my LS1. What do I need to do to make this work?

Heres what I got so far:

1. Fuel rail spacers/ ring kit from Katech
2. Injector adapters (LS1/ LS2)
3. Wiring harness adapter (LS1/LS2 for the IAT and other sensors)

You guys got anything else?

Your question is confusing. A 112 or a 122? The 112 is sold as a direct-fit kit for the LS6 and LS2 CTS-V.

Yeah what ^^he^^ said.

There are two MP112 kits for CTS-Vs, those for LS6 and those for LS2. As far as I know, GTO and Vette kits have some slight differences. Other guys here can maybe tell you what those are ... I can't.

I could be wrong but I think the main difference in the kits is the accessory drive spacing in reference to the blower snout.

Contact Blownchevy...he's the man at Maggie. From 112 to 122HH is the same as going to the TVS2300 from the OEM I'd suggest. My experience is with the Truck 122HH, but far as I know should be able to work without much alteration...Brian (blownchevy) will definately be able to help.

You will need a different throttle body snout or step up to a 90mm that comes on the 4th gen. I actually have a 78mm snout if you need one. Its for a V so make sure its the right one. The accessory drive will be the same from a 3rd to 4th gen. you will need a different valley cover. LS1 have the knock sensors in the valley where the LS2 has them on the side of the block. MAP and IAT sensors will need to be relocated. I'm sure there is more but that's all I can think of right now.
