Hello Longbow welcome to YT! I suspect there was a little color confusion by 300jk but I might be wrong. John Deere also had a 4000 and 4630 model. The JD4630 had a 404 CID with a turbo and after cooler to make 150hp. So if the thinking was you were making a green to blue swap that would explain his comment.

The same company also made a kit for the next smaller model the 3020 which was a 70hp tractor with a 270 CID 4cyl. diesel. In that case the turbo on the 4cyl. just did not seem to have the power increase in comparison with the one for the 6 cyl. model.

The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony.
