Im trying to figure out what engine is in my 1996 mustang gt.

Attached is a picture of a 4v motor in a GT- Mine.

That is a PI by the looks of it, which is nice because you have 30-50 hp more then your stock motor would have... but thats just by the looks of it. Without taking off the intake there isn't a way to tell.

One thing I can tell you that is wrong is that they didn't tap the water crossover for the two coolant sensors the 96-98 GT has, maybe he did a wiring swap. Not. It has coils, not coil on plugs.

IF they did do a complete PI swap, you are gonna be sitting about 265hp. If they did a head and intake swap, you could be sitting a little more, if your stock motor was in good shape, as it will have raised compression.

Either way, check for unhooked wires, make sure your AC and cooling fan work (one sensor runs each that you are missing) and get it scanned for codes. It is NOT a cobra head swap, but you may still be one up anyway!

Hm well he sweares they are, So i guess what can i do to get more out of this engine? So theres no way thats those are cobra heads? what would have to be done to but cobra heads on?

They are not. You can do anything anyone with a GT can- and IF they are PI heads, you can do anything that the 99-04 GT guys can... in moderation. Your car NA if it is a PI head swap will be better NA, as you will have higher compression. IF it ISN'T just a head swap, then you can select from a vast array of blower setups, and still run your 6-9psi, Good for about 400ish HP.

Since you have a Termec transmission, they very well may have found a doner new edge GT, and just did the entire swap. Like I said, pulling your intake and doing a compression test are the only ways to know for sure.:bigthumbsup


AS for a swap, here is what you will need to do just the motor:
Nicks 1997 Ford Mustang GT
Mark VIII 4v Motor Install
Parts and Mod Guide
NEW PARTS REQUIRED:

1994-1998 Lincoln Mark VIII 4v motor, complete long block
1997-1998 Lincoln Mark VIII Intake and throttle body
1997-1998 Lincoln Mark VIII Throttle cable
1994-1998 Lincoln Mark VIII Fuel Rail
1994-1998 Lincoln Mark VIII Alternator
1991-2004 Ford 4.6 Motor Mounts- Mustang/Cobra
1994-1998 Lincoln Mark VIII water crossover and thermostat housing
1994-1998 Lincoln Mark VIII/ 96-98 Cobra IAC
1996-1998 Cobra IMRCs/1997-1998 Lincoln IMRCs
1996-1998 Cobra spark plug wires

REUSED PARTS REQUIRED:

Mustang GT power steering pump
Mustang GT AC pump
Mustang GT Flywheel/Clutch or Flexplate
Mustang GT starter
Mustang GT fuel injectors
Mustang GT wiring harness
Mustang GT MAFS
Mustang GT radiator
Mustang Ignition coils (COPS if later model GT is used)

NEW MISC PARTS:

1 clay pipe 4”-3” reducer
1 4” OD 90* elbow
1 4” OD to 3” OD reducer
2 universal 90* PCV valves
Hoses as needed

to swap onto your motor, you will need heads, intake, timing cover, oil pump, timing chains, valve covers, fuel rails, throttle body, injectors, MAFS, and CAI

Theyre are cut wires that have been shrink wrapped with new ends and wires and plugs that go nowhere in numerous spots. Engine light is not on. I have noticed this, The plug that goes into alternator has been cut off and replaced with a different hookup. The alt on my car is for a 99+ gt engine. Bolts on perfect. What else could i look for to figure out what engine and or what is done to it so i know where im heading. BTW this car and engine ( if its the stock 96 engine..) only has aroun 75,xxx miles on it.

You forgot to put an RPM switch in your list to activate the IMRCs if you're going to use the stock GT computer.......:bigthumbsup

Ok ill post some pics when i can of the intake pulled. SO its for sure a 2v engine? Also the stock 96 block with a pi swap MAYBE? Or could it be a 99+ engine? I start gettin lost when going in to detail about everything. 99+ gts are 2v or 4v? Edit> Also my speedo is way off.. When im goin 40ish it reads 80+ so i have it unplugged. Where would i get the part to fix it? I need the gear behind dash or in transmission? or both? Lol

ALL 96-04 GTs are TWO VALVES.
IT IS FOR SURE a 2v... Look at my pictures, does yours look ANYTHING like that?

Get the intake pulled, get pics. My email is [email protected]. Email me with any questions and Ill help you get the wiring taken care of- and the broken sensors all over that thing replaced. I have everything off my 2v, and it was a 97 with a PI swap, the right way-

Hahahha nope! I zip tied them bastards open! IF you are going to use functional IMRCs you do have to run an RPM switch

:rollgrin::rollgrin::rollgrin: That's one way to do it. Since you're going supercharged, you should just pull the IMRCs, take the plates and rods out and epoxy the holes, and get rid of your zip ties.

I would never suggest deleting the IMRCs on a naturally aspirated engine though, you'll lose too much low end torque.

Sorry for the thread hijack, but.........

to the op:

That's definitely a 2V engine, no doubt about it. I would say since it has a Tremec in it, it's probably a complete PI engine, not a headswapped car.

about how long of a job is pulling intake manifold? A good hour? Ive done it on my old 5.0 but just tryin to get an estimated time. (my first 4.6) Another thing i have noticed. My oil Filler is on passnger side and stock 96 engine is on driver, and again alternator is from a 99+gt. Oil Filler have anything to do with it? Im guessing not. lol EDIT:: Also if its a 99+ engine does tht mean i have a 99+ecu? Ive tried lookin for the Computer reader plug and i couldnt find it. it may be one of the loose plugs under hood by any chance?

Hmm well theres 12 on driver side and 14 on passenger(side with oil filler) That sound right?


Ok its 13 and 14.. The driver side cover is the wrong one it looks like. It said on the barcode, Ford Windsor 0a103aa. But Ill upload this pic, It doesnt cover on of the bolt holes.

I dont think it is missing one, that doesn't look like it has had anything in it in its lifetime. Pulling the intake is an afternoon job the first time. The EGR can be a butt, and the fuel rail will also be a pain, but aren't horrible. Also, take a picture of the belt routing if possible. To pull the intake, all you will need is a #10mm and a #8mm, a few extensions, and a ratchet... MAYBE a pair of pliers.... then, just have at it!

Here are a few pictures that i took of some things. The first one is a picture of an Unplugged wire that i have no clue where it goes, The wire runs into the passngr fender above tire and then goes into firewall. Its group of wires and before it runs into firewall it breaks off and goes into a computer box mounted above tire.

Second is another unplugged wire hangin above the one just like it but its plugged in.

The rest are just random pictures of belt and other things. I was looking at 96 Engine bays compared to 99+ and some of the other pics are diff. Ima going to try and remove heads tommrow, im sure that will be alot more helpfull.


The last picture i just found out is a EGR valve off of a 99+ mustang gt. Looked up the NUmber on the tag. Idk if that means anything.
