burnt piston #8 what should i do

[bigsuperduty]

number 8 injector stuck open and fried the piston so if i gotta pull the motor out ima egr delete it new head gaskets arp studs and plrt the heads what could i do to get the most hp without breakin the bank? Or should i jus put a built 12v in it

sorry to hear that.

you can get everything rebuilt and add a bigger turbo and gate. thatll probably be the simplest. to get more power out of the turbo you can add fuel and get bigger injectors.

you can go another route and get cams, pushrods, rockers, springs etc would really strengthen your valvetrain while giving you a flatter powerband.

or you could do both haha. elite diesels, rudys, rcd, mpd has a lot parts you might be looking for.

good luck with your build.

Yeah i need to get a prcie on all the parts i do have a 03 common rail cummins motor jus sittin but i love the power of my 6.4 jus dont want to spend 10k and still get ****ty fuel mileage

[Capt dong]

i think fuel mileage will depend on how you drive it and your drivetrain like gears, suspension, tires etc... which you already know. im getting 16.25 mpg a tank hand calculated with my mods and very conservative driving habits. however it still wont touch the fuel eco of a cummins.

i guess in your situation its cost vs power. im thinking by the time you spend money to add power to the 12v to match the 6.4s level youll have spent as much and the fuel mileage will decrease. i could be wrong though. not an expert on the 5.9. but that is part of the fun of rebuilding or converting is deciding what you want to go with.

If a 6.4 is set up correct, it shouldn't get terribly mileage. I don't see why you'd put older technology in a new truck anyway.

Idk ive always had cummins and strokes i still have two 12v trucks and a 7.3 truck idk i jus gotta figure out what its gonna cost to have my motor rebuilt and new mods i would love to keep the 6.4 jus dont wanna spend so much money it does have 145k of hard miles on it and has been to the dealer one time fpr.coolant leak on the radiator hose thats it never had any problems out of it jus need a idea of what its gonna cost to get it back rite

[Capt dong]

if you were to rebuild the 6.4 would you do it yourself?

[levan4076]

isn't it illegal to put an older motor in a newer truck? just wondering out loud, also if you did the swap you would need to check that and maybe get it retitled. making it a salvage title

A cummins conversion in a Ford is Expen$ive. I talked to Beans Diesel about one for my 6.0 and out the door was like $20k. They said they would have to swap out transfer case, tranny, etc.

I jus did my dads f450 it had a 6.0 in it we put a 2000 cummins 24v in it and kept the ford trans and t case jus bought the adapter plate motor mounts wiring harness and trans computer got bout 6k in it with the motor
