Engine Swapping / '88 T-Bird 4.6 DOHC swap.
Quote from: TheFoeYouKnow;446915
The Coyote seems to have a lack of low end torque only because that's the way the electronic throttle body is calibrated.  The software is intended to reduce shock to the driveline.  I'll bet if the Coyote had a cable actuated throttle, nobody would be talking about it's lack of low end torque.

That's interesting.  Are you saying that it opens slowly or doesn't open all the way to reduce driveline shock?  The throttle probably doesn't need to open  more than 30-50% below 2000 RPM to get to atmospheric pressure (WOT equivalent).  I guess I'm thinking if the throttle doesn't open all the way it doesn't mean you're not getting full torque.

Are the 3V block mounts the same as the 2V and 4V? If so, aside from the water outlet issue, some of my Type 9 mounts with the early lower brackets may get you in the ballpark. Not sure of other clearance issues, however.

You can use 2v mounts on the 3v engine.  It is what I did.  The dipstick tube needs a slight rebending.

I like the DOHC because it gets pretty good power, and I'm a real nerd for DOHC efficiency. Plus naturally aspirated, that engine in that size car would likely get good mileage. I'm hoping better than what the V6 gets at around 25 MPG. Also I'm kind of afraid of the costs and complications with doing ports etc with the 5.0 Windsor, especially if it'll kill my MPGs. If I had the money and resources I'd put in the Duratec 3.7 V6 with the Mustang 6-speed tranny. 305 HP and 31 MPG rather impresses me. Anyway I'd like to at least look at a couple comprehensive write ups for swapping the Mark VIII motor, just to see what I'd need to do as far as the suspension and fuel system and mounting brackets etc. Google just hasn't been so kind. Found a video from a guy who did the swap in his '97, but no details or schematics etc. Even if I eventually decide to abandon the project and just fix the current engine and rebuild the transmission, I really want to at least get the info. I was thinking stick in the axles from a Turbo Coupe and interior from a 5.0 with a floor shifter. Otherwise sticking in a 5.0, especially going simple with stock would give me nearly identical power to the V6 but leaden the handling with the extra weight and probably lose some MPGs.


I just sold my Mark VIII which weighed about 400lbs more than what the Tbird would weigh with the same engine and got between 17 in town 24-25 mpg on the highway.  you may get a little better mpg but may not depending on your gear ratio.

One thing to remember on the newer V6 is that you sacrifice some low end torque and it will feel doggish compared to bigger displacement.  305hp is a number you'll rarely feel, 250 ft-lbs @2-3000 RPM you'll feel every day.

Lounge / Fox Cougar and Thunderbird movie sightings... (Updated 2/23/15)

All the ones on the bottom look to be that same '88 XR7. Might also be in Cloverfield.


You can actually see the plate in Pride and Glory matches the 88 XR-7 in Along Comes Polly, BHX 7697, so it's the same XR-7.

Eric also references a site IMCDB which stands for Internet Movie Car Data Base and if you search 1988 Cougar, you don't get near the references that Eric has but you do get one from The Other Guys 2010 that looks like the same famous 1988 Cougar XR-7.

Suspension/Steering / Use of Hydroboost
I'll chime in super late on this. The only reason hydroboost is used from what I can remember is when engine vacuum isn't easily available (turbo, diesel) or the brake booster won't fit (sn95, new edge mustang). Hydroboost actually takes power from the engine by loading the power steering pump.  Vacuum power robs no power, so why not use it if you can?

User Rides / Five Lug conversion
I also sold the parts car minus the interior and a few Cougar accessories to a guy in town that's also on the forum (see Engine tech).  He's dropping the 5.0L into his Turbo Coupe.  I also sold him my four lug Cobras and it got me looking into other wheels and I stumbled across some new ones.  I've always wanted to keep the stock look.  If I could find something that resembled the black turbines that allowed me to go five lug and a 17 or 18" rim I would do it, but I haven't found anything until NOW!!  I'm pretty convinced I'll be doing a five lug swap and buying these.

User Rides / '88 Cougar XR7 4.6L 3V - update 12/27/2011; Engine, trans and TC rear end in
Minor update:  I got the Hydroboost from a 2002 GT fitted in the car, and because the mod motor is so much wider, the master cylinder is angled up and the MC rod doesn't line up with the peg on the brake pedal.  So I had to take the automatic pedal, grind the weld off and knock the peg out, slice off the peg on my manual pedal that is going in the car, relocate and drill the hole and reweld the peg into the pedal.  Here are some pics.

Then I had to trim the mounting plate on the MC and open up the firewall holes and finally got the brake pedal, steering column and master cylinder mounted.  are some pics.

So I don't think anyone still really follows this thread but I'd like to mention that i have found a donor for this project. A 1988 Mercury Cougar XR7 parts car that someone from this forum had and used for the interior Seats, etc.. SO PROJECT IS A GO!!! Will be starting tear down Monday. :shakeass: :burnout:

What a coincidence! I just sold a 1988 Cougar XR7 parts car today!  Good luck Grant, and good dealing with you. Let me know if you need any help.  I'm looking forward to seeing how your project turns out.
