4430 injectors

I have a farm stock 4430 with a 3LM turbo on it with the Apump maxed out on the screw. I was wondering if I would install 6030 OEM injectors in it if that would give me more fuel/HP at all or is my pump my limiting fuel factor at this point. Thanks |

Are you still 404 CID or swapped to 466 CID? What 3LM turbo are you using? What style injectors? I know of guys that install 4840 or 4850 injectors (but that depends which engine you have and what style injectors you have) and that makes an improvement. I'm interested to learn more as well. |

It’s a 404 block. Y style injectors (old style) and the part number on the turbo is 178100. I’m thinking it’s a 3lm-466. |

According to the part number its a 3lm 259. If you can run a s300 either the older version or newer one per your rules, you should try either. Approximately how many cc of fuel? |

It’s a stock pump at the moment turned all the way up according to the dyno. Not sure how many cc it’s putting out. The turbo I have is basically new. Just was wondering if these new injectors will be worth putting on or if I should just send the pump off for it to be gone through. |

I’m not jd person so I don’t know anything with what they can put out with stock fuel. Does it clean up or is it smoky? Even if you try to get more fuel from either pump or injectors or both, the turbo is going to be the limiting factor eventually, but like I said before and localpuller said, get you an s300 variant or a s257…..stock turbos only do so much. |

It’s a clean pipe when you’re at the end of the track. Lots of smoke puttin around but it sounds like money will be spent well with a S300 and some pump work and injectors for a healthy mph classes |

If its a 3lm 239, that will be your limiting factor not fuel. Need air to burn fuel as well. A small S300 or big S200 would be beneficial |

That is true, I’m just trying to figure out if I put a S300 on how much cc fuel would I want to feed that air. Just wanting a healthy B3-B4 gear tractor. |

Sounds like you are going to
Need a good 10 mm A pump, bigger injectors like 4x22’s and a s300 turbo. You can get a turbo off of a jd 8.1 engine which is a s300 or can buy other ones, they make several different sized ones and styles. Then the head gasket will probably become an issue …… |

There is a 12mm 750cc pump on the for-sale page by 55 addiction. Have you advanced your timing? |

No I have not, that just entails rotating the pump which direction? |
