![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=21)
old v6 looks kinda small dont it ! ! !
![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=8)
i had to remove the v6 gas tank and rear end to install 1999 cobra IRS
and 1999 gt fuel system
![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=2)
whats that, just a simple cobra independant rear suspension with 3.27 gears beats the stock 7.5 and 2.73 gears
![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=15)
eew cant love those headlights
![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=30)
almost looks factory, next step 410 gears and maybe a supercharger if i get lucky

engine needs a good cleaning! cleaner up and now includes a new typhoon intake manifold
![](http://www.gotstang.com/photodisplay.php?useruid=1127&showimage=9)
just a few add ons to go with the engine swap
bbk shorties, c& l cold air intake system and bbk throttle body
installed and ready to go

wife posing next to the car,
now hows that look , i did the top myself,

for all of you who said pigs would fly before i got this done ! !
********
First off let me say if you are planning to do this, you better have a lot of knowledge on cars and the working of newer cars get something like alldatadiy or a mfg manual for both cars.
Also prepare to have your car down for an extended amount of time
Mine was down 3 months mostly for waiting for parts to come in and trying to figure stuff out
My total cost is 5780.00 for the entire swap
This is a basic break down
All hard parts I listed above 1750
Wiring 600
Labor 2250( does not include my personal labor of about 100 hours)
Sct tuner 400
Irs 780.00
Ok for swap
First remove everything
I mean engine trans wiring dash interior ect until you have a stripped car
Then put it on a lift and remove entire fuel system be careful , gas tank is heavy if anything is still inside it but even if just a little it is awkward to take down( recommend 2 people)
Fair warning, do not pull or cut any wires 1 broken wire will cause you hours and hours of headaches
Ok I was lucky because all my parts were removed from the other car for me
But if your doing from car to car first do the v6 ( swap to car) car first, put all the parts aside then as you remove parts off donor car install them onto the other car
You will notice things different, like the door pin connectors for your dome lights, the fuse block does not fit in the old spot because it’s a different size ect
Other than that the body of the 1997 and 1999 were almost identical( but not 1 wire was the same) and wiring was perfect(note 1994-1998 h pipes are a different angle than 1999-2004 buy the h pipe based on the body not the motor)
Ok onto my swap
We pulled all the 3.8 stuff out pretty simple kept everything just in case we needed anything
Installed 4.6 and all accessories wiring, ac, abs, cooling ect
Everything fits, we did have to drill a few holes to mount things
But the harnesses fit into the same positions, engine trans and drive shaft fit right in and bolted right up to the 7.5 rear end
Dash wiring connected to the ac system, but I cannot find a wire for my clock, its ok who needs a stupid clock anyways
Headlights and turn signals were just plug and play,
Note 1 big problem was mounting the fuse box and gem module
I used a small cut off wheel and trimmed the metal to fit the fuse box, then installed it, gem module is zip tied to the kick panel
Air bags are disconnected would need to get 1999 airbags and the sensors to make them work
Since the p.a.t.s. system on the steering wheel for the 1999 was completely different than the 1997 and I didn’t want to tow my car there just to get them to charge me 300.00 for the pats system, so we went to jms http://www.jmschip.com for a sct tuner to bypass the pats and turn off the rear o2 sensors also added a nice tune to the car.
update .... i would like to note, i have been having problems with the jms tune. 2 things mostly
#1 between safe, moderate and performance tunes, i cannot tell any difference and with 93 octane
#2 there seems to be a problem with the shift points and as far as i can tell it is due to the tune allowing them to shift as soon as the predsure builds up instead of holding the gear
Went to start the car and hit 2 problems
The constant control relay module was buzzing, thanks to some help from a local ford guy I found out it only buzzes when it is not grounded properly so we knew we had a break somewhere in the wire, instead of taking days to find that wire we just tapped it near the relay box and grounded it to the body directly got instant power , tested for spark and tested to see if fuel pump was priming , then final test was fuel pressure.
At this point we were ready to crank her,With only an h pipe,
We cranked her over but nothing , she just spun but didn’t kick
Tried a little either and she started right up
So we knew it was fuel,
Injectors were stuck, all 8 of them
So we pulled them off and cleaned and cycled them , stock them back in and she started right up THEN darn a fuel leak
Shut her off and looked around, someone stuck the rubber line onto the steel line but did not lick them together (points at self) and forgot to put the little plastic clip so she popped off, fixed her and she started right up
Just needed to bleed the brakes and make sure everything was tightened up on her
Now a few pointers
1.When you start to put things on the car, tighten them up as you go, you may thing you will get back to them later, but you will forget there are too many components going on so tighten as you go( its better to tighten them and have to loosen them instead of forgetting and something falling off later)
2. do not pull on your wiring harness, it may seem strong and you may thing its ok, but we somehow broke a ground and never found it, also the previous owner pulled off the turn sig wire when they took out all the old wiring, so we needed to fix that
3.dont try to just make stuff fit, it wont, even if it does it don’t mean it will make the proper connections
Many people will say for 4600-5800 I could have went out and bought a 1997 gt or even a 99 gt ,
But let me tell you it was a project, i like projects that are fun and keep me out of trouble
I now have a 1997 gt convertible with only 88,000 miles on the body, it has a 99 pi engine, a sct tune h pipe rear o2 deletes,( 1997 gt and v6 use the same rotors and calipers, 1999 gt uses same rotors but different calipers)and I know the car very well now
So lets say I went out and bought a 1997 gt, then I did a pi head and intake swap 800-1200 dollars, sct tuner 400.00 h pipe 200-350
That’s 1400-1800
,
Note, I deleted the abs, and air bags.
have added cobra leather seats and had the car repainted due to a ford probe kissing the mustang's butt,
also added a pioneer in dash nav / dvd player
drilled and slotted rotors on all 4 wheel
17" american racing hopster wheels

Whoa...
I had no idea there was so much work put into this, and definitely had no idea it started as a V6.
Wonderful job! Absolutely wonderful work!
