John Deere 9300/9400 engine specs

We have a 9300 that we were thinking about putting a TS Performance Agri-Power 65hp chip on it. This would take it from stock 360hp to 425hp which is the same level as the 9400. I know both tractors use the 12.5L Powetech engine. Do they use the same turbocharger, intercooler, radiator, injectors? If they do then we know we could add this power without raising the EGT beyond safe levels and without overheating the engine. If anyone knows this information or where I could find it (Google was of little help) it would be much appreciated.

Computer is giving me fits trying to get the info for ya.

I would imagine the injectors and turbo would be different. All else should be the same. Either way, a pyrometer is the best way to know the EGTs. The owners manual only gives a minimum RPM limit for heavy pulling. Not good enough for me in tough conditions. Especially in the summer heat. Besides, a dirty air filter and plugged cooler fins make it that much important to know the actual EGTs.

OK. Got more info. I was wrong on a couple of parts. They do share more than I thought.

Unit injectors- 3 different p/n based on ESN. Shared on both the 93 and 94.

Turbo- Same

Radiator- Same.

CAC (intercooler/aftercooler)- Same.

Axle shafts- Same.





Looks like you are good to go! Just add a pyro.

The main split I saw, was between the 91-9200 and the 93-9400 tractors.

Awesome! Didn't think ther was much difference. The 91/92 use the 10.5 engine the 93/94 use the 12.5, we have a 9200 and a 9300 and dad just wished we had a 9200 and 9400 so this will be a much cheaper upgrade.

We used to have a 9100. It had the 8.1L in it. Far more fuel efficient than the 8300 it replaced, but still should've gotten a 9200. Just wasn't quite enough power for the ripper in heavy gumbo. 91 got traded for a 9320. That just got traded off for a 9430. We'll see how this one pulls.

Oh yeah that's right they had the baby engine in the 9100 that one competely skipped my mind. I've run a 9530 before, after getting off the 9200 I was impressed.

I believe the 9600 is a combine

we replaced a R5 gleaner with the 9600. it made harvest a lot less stresfull. there were a lot of ruts around here last year. we have 42" duals, and virtually rut free. the R5 would of had 12" deep ruts. we have a 1969 gleaner k i would put up against the R5 any day. had to finish some beans a few years ago the R would not combine, it would not throw it out the back to the spreader.
