Hi,
correct this if its wrong,
I read that you can swap an 03 engine in a 98 with no big modification needed :you need to use your old upper intake, wiring harness, cam sensor, old fuel rail (including your old injectors), old exhaust manifolds, old EGR valve, bracket, and pipes
ECU '97-'03 will all interchange. Some things are different in all of these years. Most are minor. Don't change out your ECU.
You can save some time if you use your old valve covers if not you have to deal with: The coil pack, upper radiator hose, PCV valve(s) , spark plug wires/mounts, DPFE sensor, and the main electrical harness connector bracket. If you use your old valve covers all of these will match up as on the old engine.
The cam sensor, oil pressure sender, and block ground appear to be the only sensors/connectors you’ll need to use from the older engine. use all the sensors from the newer engine except for these three.
You need to use your old heater hose bracket/coupling.
Do you know if we can swap a ‘11 to a 99 and that it would be the exact same thing you have to deal with, since the engine '03 are nearly the same as '11
99 ECU is still interchangeable with an '11?
can i use my 99 5 speed manual tranny with the newer engine?
thanks
