I will give my opinion. I think the turbo or altitude compensator was designed for the 504 diesel engine of the A4T-1400. I read somewhere a few years back that the A4T had a stronger (maybe thicker) crank than the G1000, 1050 etc. and only the A4T crank could take a turbo for prolonged periods such as farming. There are lots of pulling tractors out there with the 504 or 585 engine and a turbo. My cousin has a G1000 that he has lots of fun with.
