How big a deal is it to put EFI on an older model car? Say, a 75 Ghia II??? I've been thinking that this would make it a more drivable daily driver. Anyone done this???

It's not too difficult of a job, especially if you stick to an EEC-IV controlled computer.

The fuel system needs upgraded with high pressure fuel lines and fittings and a high pressure EFI fuel pump, plus a return line.

The electrical is pretty simple since the EFI usually uses a seperate wiring harness that only requires a few connections to the Mustang II wiring harness. I believe I only had to connect 4 wires for my 2.3L Turbo.

If you go for too new of a motor, the EEC-V is a bit more difficult to hook up. My roommate did a '97 SOHC 4.0L swap into a '74 Capri and the wiring looked scary for a while.

Hood clearence can be a bit of a problem too dependig on what intakes you use... I used fox T-Bird manifolds on my 289 in my '78 II... Had to modify for a different style of throttle body and eliminate the egr... Still pretty tight.... I'm currently working on making an upper intake that'll work with the truck lower intake that'll give me more room..

Haven't gotten anywhere on the intakes yet.. But I just read an article in the back of I think the January issue of Car Craft talking about a company called Probe Industries that adapt Edelbrok Torquer II and Victor Jr. intakes for EFI.. CHecking into that as we speak..

As far as parts, I bought an entire running car with a bad tranny and took all the injection whatnot.. Wiring harness, intakes, throttle body, throttle linkage and brackets, sensors, ecm, distributor, etc.. Had to swap a few pins in the injector harness (Was a 5.0 HO with the Windsor firing order) I think I one thing I would change would be to use the mass airflow injection from either a 91-93 Tbird/Cougar or I think 90-93 Mustang with a 5.0 HO.. Seems to have better throttle resonse, and allows for engine modification. They also have the TFI ignition module mounted to a heat sink that can go in a nice cool place instead of right on the distributor..(at least on the T-Bird/Cougar)


For the fuel pump I first used the high pressure pump (the one on the frame rail) from an 86 F-150. Mounted it to the floor pan in front of the gas tank... This worked fine unless you ran it outta gas.. It was hell to get primed (and yes it was raining). So anywho I added a cheapo electric pump for a carburator in it's place, and put the high pressure pump under hood on the fender well.. Fixed it right up

For the fuel lines I ran 2 new ones front to back.. Took the sending unit out, driled a hole in it, and soldered a piece of line into it for a return and kept the original pickup.. I have an inline filter after the low pressure fuel pump..

The hardest thing was finding a place to put the ECM (AC doesn't let much extra under dash room) I finally monuted it above the plate on the driver's side that goes from the steering column to right above the kick panel..

It's kind of hard to explain how I did the intakes. It involved cutting, grinding, drilling, tapping, and JB weld.. It works but it doesn't flow all that well, and it is still VERY close to the hood.. I was considering a 5.0 Power Box as an upper intake replacement until I saw how big the ports are in the truck lower intake.. As of a few months ago there was no other upper intake available for the trucks.. But all it really needs to do it tie all the ports up to on location where you could mount a throttle body..

I was hoping to attempt to make an upper intake for the truck lower to see what happens but the brakes and rearend went to crap so everything else got put on hold.. I'll keep ya posted on what I find out about these intakes from Probe Industries...

I haven't tried it but I've been told that the holley upper will fit the truck lower.
When I look at my truck lower all I can see setting on top is a Holley [B&M] blower.

http://www.geocities.com/maxwell_fax/stangeng.html

And yes I know it's all sorts of a dity disaster under there... Once everything works as it is supposed to the whole car is going for a makeover... In the meantime I'm still waiting for some local kid to crunch his 91 Mustang GT..

Well, the local kid crunched his 91 Mustang GT.... Ran it through a house.. We are still trying to negotiate a deal... That's about it.. The II's beeen sitting for a few months now.. It's in need of brake work.. Finally decided to give up my stock wheels and do the brake upgrade.. Now I jeed need to get to it..

A friend of mine got an intake from Probe industries for the 351W in his 89 Cougar.. It's a slick little item, they also offer the throttle body adapters and all the fittings and hardware for the fuel rails..
They seem a little pricey but the fact that everything is supposed to woek together is nice although we on't actually have it on the car yet to see how it all works he just got hitched so it could be a while...

Right now I'm in process of injecting the 351c in my Gran Torino.. Found a 93 5.0 T-bird with a bad engine and alot of body damage.. For the intake I decided to be a cheap *** and make all the stuff myself.. Bought a used Edelbrock Performer intake and had a guy at the local machine shop weld injector bungs in it.. (same thing that Probe Industries does) I think I may buy the fuel rails and hardware from them though.. I already have a throttle body adapter made..
