Well i have a 02 F-150 that ima start building. I also have a 00 Navigator that i plan to get rid of. I don't enjoy 8.9 miles to the gallon out of the Navigator,but i love my Truck to dead. well i was sitting down one day, and asked myself, "is doing the head swap to a 4v worth it for a (what will be) a Nitrous F-series". I mean will i see any improvement without the Unit (Nitrous). I have the car here sitting. I have both as weekend cars and downtime is not a big issue. Do i need to swap over ECU's as well. cut wires. any big mods to do so. i did plan to do a STS turbo kit, but i think i will piece my own kit together once i get ahold of a Gt3082R or a HX40 turbo. Thanks guys for the help. Sorry if it's a newb question.

 

I would do an entire drivetrain swap. The Navigators have a forged crank and I believe a 4r100 trans as well. You could probably use the wiring harness from the navi as well if there were any wiring issues. If you have the entire vehicle as a donor then why not.

 

there's a lot more work to just swapping the heads.

like gotts said: swap the whole motor, trans drive train wiring harness and ECU

 

check out the supercharger forum I'm trying to organize a group buy for the STS turbo's

 

i wish i knew how much work i was getting myself into before i went ahead and started the swap.

 

well, anyway


you need to run the ECU and torque converter for the transmission you will be using. the wiring will be a plug and play into the F150 engine bay. all you will need to swap is the complete engine itself, the engine wiring harness and then get a custom tune.


good luck on the swap
