turbo on a 4230?

we have a 4230 john deere tractor and we are interested in putting a turbo on it

would this work/fit?
For those who have been around or done this to one of these or a tractor simular what are your experiences?
how much in a ball park would it cost?

thanks for the responses
Austin

Wrong compression ratio. Need to change the pistons.

Used to run a 4240 that had a turbo added on.
Made it almost into a 4440.
Had to watch the pyro and the engine temp when pulling it hard. It would heat pretty easy.
Loved the chrome stack, no muffler.

Re: turbo on a 4230?

would it be a feesable job? just would like to have more power


how would the transmission/rearend hold up to any extra power?

I think it will add 20 to 25 more HP and if you want more will have to go in the injection pump screw to get more, need to monitor the exhaust temperature like dutch said.
Can you get a new turbo kit.
The rearend is only a two pinion so that can be a problem and the transmission will be ok.

Re: turbo on a 4230?

we dont plan on messing with the pump all that much bc jus pulling a planter with or without the splitter when it is not on the 756 and then on the john deere 400 or 1210 grain cart in the fall so would not be pulling the #### out of it so is it worth it?

Re: turbo on a 4230?

IIRC, the 4030 and 4230 shared the same tranny and rear end. Not much extra capacity there.

Why not either trade up to a 44X0? Add the money you will spend on the upgrade to the money you will lose on resale for a non-stock engine and you have came close to buying a 4440.

Re: turbo on a 4230?

My neighbor did this to a 4240 a few years ago. He used a 4320 exhaust elbow so it comes through the hood in the sock location. Made a nice little tractor out of it. Where at in western Illinios are you located? If you use used parts it fairly reasonalbe to do.
