engine swap

indytrucks · 09-08-2003, 08:01 PM

i was wondering what all i would need to swap a speed density 5.0 h.o. into an 83 mustang. basicaly how hard would it be to go from a carb to e.f.i. ? i have an 88 lincoln mark vii and i found an 83 convertable stang for next to nothing in great shape with no engine and trans. they were both automatics so that wont be that bad and they were both v-8's so thats good suspension wise.

now what could i use off the mark as far as rear end swap\ 5lug conversion?

I believe you'll need the wiring harness from the EFI. I think the Mark VII rear end is a little wider but will fit. I don't think I'd use it though...

I'm sure someone here has messed around with that type of conversion and can give you more help. Good luck..

indytrucks · 09-09-2003, 04:50 PM

hmm.. any others know any thing? i was thinking too about the rear end being for an air suspension car, so it would be a big hassle any ways. the conversion is the big question.

fastas69 · 09-09-2003, 08:44 PM

I have a 84 convertable, I swaped everything from a wrecked 87 gt, It took me about a week to get it in and running. It was actually a easy conversion. Well worth it I thought. As far as that rear end goes, I wouldnt use it..........Just my .02!

indytrucks · 09-14-2003, 07:36 PM

acttualy im using the speed density engine out of an 88 mark vii lsc. so, what all do i need of the wiring harness?

is there anything else i need?

desertrag · 09-14-2003, 07:48 PM

You can use the front rotors and hardware from the lincoln to do the front.....for the back, use 2 right side axles from a Ranger pickup with the 7.5" axle, along with the drums and backing plates from same.

FYI, just ran across something you might like......Ebay item #
2432199268...check it out,good luck.

gtnby2 · 09-17-2003, 08:45 AM

This guy wants to know about what he needs to do the engine swap.....NOT the rear end. Take the harness out of the Linc and just go through and plug in what is obvious. I've never done this before but with a little attetion to detail it should go smooth.
Good luck

desertrag · 09-17-2003, 02:41 PM

Well, I must have read his original post wrong. I thought the the last line asked about converting to 5 lug.........sorry.

indytrucks · 09-17-2003, 09:26 PM

i did ask about the five lug but im more concerned about the engine swap. so would it be a good idea to get a diferent computer or use the stock linc. comp?

also doesnt the harness control the lights and basicaly evey thing up front? im new to the mustang/ ford thing so bare with me. im a jeep guy at heart.

desertrag · 09-17-2003, 10:04 PM

Thank you..................I posted basically the same question as you.I have learned that : putting in the engine is easy,if the mustang had aod then the trans will fit too. If not then if you want aod, a small amount of fabricating is required to the crossmember as there is a 2" diff in length of the trans.....which means a change in drive shaft length also. As far as the wiring, I'm just going to open the harneses and trace and use as needed,using the original sensors and computer. u just have to find a place to mount it. The exahust is no problem. The sending unit/ fuel pump assy from the lincoln should fit the tank and then use lines as needed. seem resonable?

indytrucks · 09-19-2003, 05:33 PM

so what about the gas tank? isnt there a fuel return on the efi motor?

im looking for some wiring diagrams i guess so i know exactly what wires im looking for. sorry to be such a p.i.t.a. but i want to eleviate alot of the headaches before i get started on the swap.

You will need a gas tank out of a 87-93 mustang.

drtbiker · 09-20-2003, 11:15 AM

as far as the wiring harness it isnt to hard i know a few people infact i have a complete wiring harness out of a mass air, mustang it is a little chewed up but has all the connections. I'll sell it to you for like 40 bucks or somthing if you want it. It is not that bad or atleast i dont think pick up like a chiltons or somthing that tells u all of the wires and what they do and work from there. As far as the rear end i would just go and buy a mustang rear end i think that would save you some time. Yeah with the gas tank your going to need a return as well. Someone who may have the wiring diagrams is Pkrwud maybe wrong spelling but shoot him a pm and he would gladly help. When it comes to when i have wiring problems i go to him, he is really helpful and nice to work with. Just out of couriousity what are the plans with the stang. You going to cruize with it or race it?

i hope i answered a couple of ur questions

indytrucks · 09-20-2003, 12:06 PM

i plan on making it a cruiser but i will definatly take it to the track.

doesnt frpp sell a harness? i found one from painless but it is like 600 bucks! i could make one for less, hehe. there is another place too but i cant remeber the name, its like windsor-fox i think. anyone know about them? or possibly how much theres are? i stumbled upon them yesterday and they arent open till monday so...

also i wont have a problem because its a speed density set-up will i?

drtbiker · 09-21-2003, 10:44 AM

speed density is not a problem but if i was in ur place i would take it one step further and just take it to mass air if u really wanted... yeah those harnesses are up there in $$

KiltedBanshees93GT · 09-25-2003, 09:24 AM

I have to agree with going to mass air, you would be saving yourself more headaches down the line when you have to convert again for more performance.
If you already have the motor I would just start shopping around for a mass air car thats been totaled and take the harness, brain and manifold from it.
