tuning is available and the 5.7 Tundra and 4.6L GX460 tunes appear to have the same structure from my time poking around VFtuner. It should be a matter of copying over the parameters from one to the other.

 

Also, I was told that the 1UR and the 3UR had different cam profiles. I was talking to a guy and he said that the 1UR doesnt take a supercharger as well because the cams had less lift and/or duration. Which makes sense since they are trying to get 25% more air into the cylinders through the same size valves.

 

That's good to know. I'm hoping one day I can buy a GX with a high mileage or dead engine so I can attempt the 5.7 swap.

 

@671gx570 Is it too late to ask for a video of it running?

 

Bumping. OP, any chance at some engine bay pics and a video?

 

Yeah bump. I love my 470 but everyone wants more power…

 

Sounding more and more like vaporware.....

 

At this point I'm sure a lot of us are skeptical. I want to believe but without more details and the fact that the OP just, disappeared Reddit style, after making a huge claim.

I doubt we'll ever get more details.

His profile:
Depending on funds and how quickly I can get my overlander build to a good spot I have plans to buy another 2010-2013 and focus on making it more performance oriented for on-street use. A 5.7 swap would be on the table.

 

I was really hoping to see some pics or a video. This would be such a cool swap.

 

The 1UR doesn’t need as much duration, the cams only need to feed 281 cubic inches versus 346 cubic inches.

I remember seeing a GX460 with a turbo making 700 to the tires

 

FYI: If you are on GXOR FB search for “GX570” and you will come across some threads from 2023 with pictures.
