I had a naturally aspired, '79 4230DC. 400ish cu. in. and although it was setup for a turbo, double grooves in the fan pulleys, 4" exhaust manifold outlet and room in the hood opening for a 4" stack with room for one under the hood it was rated at 100 PTO hp.
The big brother had the turbo and used what I mentioned and was rated 125 hp listed as a JD 4430. When I bought mine, Jan, 2005, it was 3,900 hrs and $17k, full cosmetic restoration including new 134 AC system, all new rubber, full weights...tight as a pin. The big brother was sitting next to it at around 9,000 hrs. loose as a goose and $19k, same restoration condition. Was not sorry for the decision.
Based upon that, if yours had one somebody put it on aftermarket.....shouldn't have been that big of a deal.... add the turbo, a little exhaust piping, second fan belt and a new muffler.

I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
