Does anyone know of any problems I will have replacing my '99 v6 engine with an '02 v6 engine?

I just bought it at a junkyard to replace my original engine with a blown head gasket. It appears that the coil pack is smaller.

Why didn't you just replace the head gasket? Did it fubar the engine?

good question

[Onemanzu]

nope everything should transfere right over... i think... wanna sell me your old motor... ill come pick it up and maybe buy you lunch in exchange for it

[Juggalo_X]

you will need to transfer over a few sensors the master harnes the ecu and the cluster because the PCM will be looking for a digital cluster as well as some of the sensors are made for the PCM that is on the digi cluster. otherwise good to go it will bolt right up to the tranny bell housing and the motor mounts.

only diffrence is the intkae manifold is split port on that year, not worth swapping

??why not just up it to a 02 v8 lol. but yeah you can do it. pretty easily actually

02-04 lower intakes have IMRC (Intake Manifold Runner Control) valves. 02-04 PCMs also have specific parameters for this system including actuation and spark (timing). Replace the 02's lower with your 99 lower.

that would work. but y dont he just grab the 02 PCM would be easer no top end work and he will have that whole whopping extra 3 hp lol and also IMRC don't it improve low end torque marginally so i say keep it and grab the 02 PCM

That's an option if he wants to grab that 3 extra horses. But then he better hope everything else works the same (IAT, MAF, IAC ect.) or there may be issues with idle or open loop operation.

i think it should be fine.... dont quote me but im pretty sure the sensors are the same swap the maf if you have to IAC would be the same cuz the TB is the same and IAT i cant see being different.... o2 sensors should be the same too....

Onemanzu: I plan on doing a slow rebuild on my '99 engine...maybe mod it a bit. I don't usually turn down free food, but I will have to this time. If I give up on the '99, I'll post and sell it later.

Thanks for the info guys!!

Mustang RacR94: Why is the split port worse than what I have? IYO

Let me say this, I bought a complete 02 engine at a junkyard (except bolt-ons...altern,compres,etc) I plan on taking what the 02 engine doesn't have off of my 99 engine and then drop the completed 02 right in.

Option 1: Replace the 02 lower intakes with my 99s

Option 2: Use an 02 PCM to control the power. First, where is the PCM located? Is it attached to the engine or the firewall or what? I probably don't have an 02 PCM if it isn't attached directly to the engine.

I really appreciate the feedback here...I plan on swapping the V6s this weekend and it sounds harder to do than I first thought.

I cant remember where the pcm is it may be behind the passenger kick panel plastic i know ur box code is there... as for the intake swap seriously keep the 02 intake on it and consider the pcm swap it should swap right over. previously i thought u were a pre 99 mustang but i read wrong so i have complete confidence it will all drop in and swap over just swap the pcm too. and the 99 engine is split port as well it just dont have IMRC in the lower intake.

Hm, I wonder how the PATs will work??? I can't remember how the coder is read. Also, check to see if the PCM still varifies the odometer modual. I can't remember if they each store syncronized readings as a form of an odometer freud deterant.

he will have to have the passive anti theft shut off by ford thats about it.

My apologies if some of this has already been said.

1. Mustang RacR94: Why is the split port worse than what I have? IYO

The 99 and 02 both are split port intake. So the 99 intake manifold should fit on the 02. This was corrected above.

2. Option 1: Replace the 02 lower intakes with my 99s

I would strongly recommend this route. Use the 02 long block as is and swap on the 99 intake manifolds and associated parts. I believe the long blocks should be the same. This would avoid potential problems with incompatability with the 99 ECM.

3. You might want to use the 02 valve covers. The 99 has a problem with sucking up too much oil through the PVC which carbons up cylinders 3 and 6 and causes preignition problems.

like i stated he is better off with the 02 engine in full with the PCM swap it will cost less, less work and will be a bit more powerful.

That may depend some on what state he is in. I don't know what TN requires, but in CA one could get into a lot of trouble installing a non original engine when it comes to emissions requirements.

Recently there was someone on here who had swapped in a later engine and couldn't get a smog certificate.

they wont even have a clue if you swap the pcm too derrrrr its when you keep the 99 pcm and use the 02 engine is where ur going to run into sensor and running issues. beleive me they wont give 2 shits and a fuck as long as it passes the visual and a sniffer. i bet they wouldn't even notice its a different engine. and like i said when he gets ford to reflash the PATs they can also match the VIN to the pcm

He has a split port engine. The split port intakes started in 99.
