Wow! Great book quotes.. ;D I was hoping for more recommendations regarding the wiring dilema vice horsepower, but something is better than nothing!
Shifting gears (Horsepower issues aside), what costs can be assumed with the swap. I might have a hard time convincing the "significant other"....
Mikey, if I get the "no-go", you interested in the whole car? I'd hate to pass over a good deal, but wouldn't mind helping another Bronco owner out..
When I did my EFI swap...I figured If I was to put all the effort and cash into the work I would want something that would be reliable for one, powerful for second, and look awesome for three. I did all of the research that you are doing. I spent time at all of the ford EEC-IV web sites that I could find. Just say no to the speed density motor. There are too many mass air model donors out there too pick from....for cheap!! There are mustang only wreckers on the web that will ship exactly what you want directly to your door.
Anyway...mass air is what you want. However, stay away from 1994 and 1995 mustang 5.0s, stay away from thunderbird 5.0s. Lot lower torque and HP ratings. Get your self a 1986-87 (california) or Federal 1988-93 mustang donor. Or better yet, go the way I did and get the Ford Explorer GT-40P motor and serpantine setup. This is more powerful (needs a new cam and headers) than any mustang motor besides the cobra (it's close though!!!) The GT-40P heads are awesome!. This is a true cobra motor, less the roller rockers and cam. (and maybe other crap). I got mine for $1100 delivered to my door with 28K miles on it. It has the best power steering pump that ford ever built on it. Turns my 40's like I had ram assist....never heats up either. It also has the 130 amp alternator stock. 65mm Throttle body stock. 2 inch shallower water pump and belt assembly. This makes it much easier to mount the fan, whether it be electrically, or mechanically driven.
Here's what I did. Money was an option, but I spent a lot!! (was single then ;D )
1. 1998 GT-40P complete motor from Ebay
2. Crane cam and lifters 1200-4500 RPM advanced 8 deg on top of the 4 deg already in cam for low end umpf! Torquey bastard
3. Scraped the EECV computer and all ignition components, and the 19lb inj
4. Bought EEC-IV X3Z cobra puter, 24 lb inj. and mass air meter from Pro-M, Mustang coil and distributor, egr eliminator kit, all new sensors including 02's
5. Expensive, but custom made for the EB, wiring harnass from
www.ronmorrisperformance.com (a local guy in Central Cali) A true plug and play system. I'm a wiring moron. I good buy for me!!
6. New radiator, flywheel and clutch, etc...
7. BBK intank fuel pump, ford fuel filter, hard plastic fuel line and fittings from Ron Morris., throttle cable and pedal, VSS for t case (unhooked it later),
the list goes on and on.
NOTE. I would not use the X3Z (93 Cobra) computer and 24lb. injectors. Use 19 lb. and the A9L mustang 5 sp. puter
I hooked all of this up...and it fired on the first try. The only issues were cam choices. Took me a few tries to get the best torque. I would run this motor against my buddies TBI 351 windsor any day!!
Anyway, you are on the right track. You don't have to hit the same route that I did, but I have seen EFI swaps that look like a rat's nest. Do it right. You don't want to be stranded out in the boonies with a motor that you cannot work on controlled by a system that is a complete mess!! Just because it runs doesn't mean that it is right!
Hope this mini novel helps. Have fun!
