Brother you are a swapping machine.

I started reading this thread said what nut would swap the diesel OUT of an 80. Saw the v8 and thought ok fair enough. LM2 shows up and now I'm over here subscribing. LM2 is a pretty cool platform IMO.

Yea my stock fuel tank doesn’t know what to think hahaha

heck yea some questions instead of opinions lol

Cruise control is doable. I don’t think the factory stalk will work, but swaptime makes a cruise control module with buttons you can mount on your dash or center console. What I am going to try to do is buy a modern Toyota steering wheel (2020 Camry to be exact) and use Trailteq’s adapter (whenever he can ship to the United States) I’ve already been in contact with him about it. And I want to use the radio controls and cruise control on it. I think that would be awesome

AC is easy, GM compressor everything else Toyota. I had it running in the LT1 and it was great. I just got to finish making the hoses. I’ll probably get that done next week or so

I thought the AC should be simple enough, but I wanted to be sure.

I wonder about the stalk. At the end of the day, the factory stalk is just 4 momentary switches (right? One up, one down, one back and the on/off button - though I can't remember if that's momentary, or if it latches... yes I could absolutely walk outside and check 😆 ). I don't think that would be any different than dash buttons, just find the right wire colors in the wiring diagram and sub them for the buttons.

One of the things I've always liked with Toyota is how intuitive that cruise stalk is, so I would be very motivated to keep the original or use a another similar Toyota option. I've never really liked radio buttons on the steering wheel (or any other buttons for that matter), but that's me. I'm very happy with my transplanted Scion head unit: touch screen AND a volume knob. Best of all worlds. 🤣

The cruise control stalk is more complicated than that. I believe it uses a resistor ladder.
 
This is an amazing thread. I can't believe you pulled off that swap as fast as you did. And the combination of the LM2 and the 10 speed transmission sounds amazing-- although I have wondered about that oil pump belt and the computer complexities. And I have always wondered how complicated those engines were and how hard they would be to swap -- the pictures of the engines I have seen look a bit crazy.

Few questions---- and sorry if this has been asked before--- was there a particular reason why you went with the LM2 and not the newer LZO?

And do you think that the LZO is also viable option, or would it be more difficult? It seems like the computers get more complicated every iteration.

I am hoping that these engines remain popular and thus become widely available in the future. It is always good to have options.

Great questions. So after you start taking off all the unnecessary things on the engine it’s a very simple diesel engine. So the LZ0 looks to be a great engine but unfortunately it’s a GM global B engine. They started doing that in like 2022 or something like that. Computers are more complex. That’s also when GM started using turn knob gear selectors on their transmissions, so you can’t just swap those without using all kinds of extra stuff, maybe one day

It absolutely does. It's a common method for builders to use 2 wires to get all the cruise buttons through the steering wheels slip rings and to the PCM/cruise computer.

I guess I must haave been aware of that at some point, but had forgotten. I think I remember hearing that Lutz Auto will modify the resistor ladder because some of the Toyota swaps don't get along without modification. What are the odds that the GM stalk uses a similar arrangement and may just need resistor changes?

Can you give a quick tutorial about how GM structures their engine families currently? What does “global B engine” mean in the grand scheme of things?

Thanks!

Sure. That’s great. These are literally all spam/selling-you-shït websites. The internet sucks donkey ballz usually.

I want a human practitioner to explain it. Like I do with Toyota systems. This guy seems to know his stuff. I’d rather hear it from him.
 
You mentioned a vacuum switch from a Volvo, what is the part number or year & model the switch came from?
 
Ok small update, so I pulled a 2000 pound trailer 300ish miles this weekend, 60% of it on the highway and it got 20mpg on the dot. And this was taken off GPS miles instead of relying on gauge cluster because it’s off a little. This was also on a “test” tune because I don’t have that completely ironed out yet. So I’m impressed with that, can’t wait to see what unloaded on the interstate will do.

Any tuning, mpg or parts install updates?

Hey thanks for asking, I have been fiddling with it trying to get it more and more better

IMG_3940.webp

I relocated the intercooler off to the side to help with intake air temps and to gain hood clearance

Added a EGT gauge that I had on the 1HDT
Changed up my air intake. Went from a 4 inch that went to the passenger side to a 3 inch towards the driver side. I was having a problem with intake air temps going up which would cause boost levels to go down

I’ve been putting tons of miles on it and I’m averaging around 28 MPG around town

I haven’t had any long road trips yet to see what MPG I get on strictly interstate.

Haven’t messed with tuning much

Problems I have so far is with electric power steering pump not being enough to turn 37s. It works great if I don’t have any rapid movements on the wheel

I have a really nice 3d printer on the way and I’m going to start designing a power steering pump bracket

I also plan on getting rid of one of my batteries and going to a AGM. I think the alternator is having problems with lead acid batteries because of the smart charging system GM has but I’m not 100% sure

I also mounted a shifter from a 6th gen Camaro I got from swaptime. It has tap shift buttons on the side. lol bad thing is they are on the wrong side but I guess I’ll have to start working out my pinky hahahaha

But the shifter feels insanely good compared to the stock shifter with the B&M cable I was using

Also in that picture you can see my custom speedhut boost and EGT gauges I had from the 1HDT
 
How's the noise? Quiet?
