LFX Engine Questions
Haven't been able to find this info and didn't want to clutter up any of the build threads.
When purchasing an LFX motor for an engine swap...
1) Does it matter if the donor engine is auto or manual if I plan on putting on a new clutch and flywheel? Any other differences between the two motors that would make it preferential to get a manual motor?
2) Are all model years of the Camaro LFX engine the same (2012-2015)?
Thanks in advance for any help!

Engines are the same but you'll need to do more modification to the engine harness from an auto to make it work for manual. V8R can do the harness modification for you if you're not sure what to do on that.

My LFX motor was out of an automatic transmission car. If you go this route you will need a custom harness as well as an extra specifically out of a manual trans Camaro. Also will need a pack of the flywheel to crank bolts for a manual trans car as the ones from the flex plate won't fit.

I work for a GMC/Buick dealership. PM me with any questions you may have. I have access to connector diagrams as well as many other things. I also pay 10 percent above cost on O.E. parts.
The LFX engine can be had from many other vehicles not just a Camaro. Acadia, Enclave, Lacrosse, Traverse, Terrain all have V6 options with displacement ranging from 3.0 to 3.6. The Camaro makes the easiest swap as it is already configured from RWD. If getting a FWD motor you'd need to swap the intake manifold and probably the TStat housing out. Harness isnt hard to modify, you'd need to swap some pins and get a manual trans ECU. I dont think an Auto Ecu can be reprogrammed for manual configuration but if you go standalone or use HP Tuners I think you'll be alright.

Schmoo, you can always extend brake hard lines and ABS module wires to relocate the ABS module wherever you need. But I wouldn't make it stray too far from the MC. Hell if there was clearance in the cowl area or under the dash it would work. Only downside to having it inside the car would be pump noise whenever the ABS kicked on.

I'm considering this swap so I'm trying to understand as many of the implications as possible for my car, an MSM.

I thought the idea was to have the coolant reservoir at the highest point of the engine which makes your choice limited. It's going to either be on the back of engine bay on the right or left. I have mine on the right side where everybody put theirs just because the bottom of the reservoir goes to the coolant return line which happens to be on the right side as well. I suppose you could figure out a way to get it in the windshield wiper area. I have an auto ECU in my car, but haven't driven the car yet. It did start at least once upon a time.

From my experience a manual PCM is required. My first PCM was a E39 out of an Auto trans car and even after changing every possible parameter in HPtuners, it still wouldn't rev over 4,000. Its like it was still looking for data from an auto trans, even though the harness and settings were all selected as manual trans.
