I recently bought a 92 mustang 4cyl. coupe. Can I use the wire hrness from my 91 thunderbird to swap to a 5.0 liter engine. Also I have heard that you must change the K-member to upgrade to a 5.0 Is this true? If so what do you reccomend

i can't help you with the wiring but all the cross members are suppost to be the same except for the in line 6 good luck with your swap

I saw this website posted on corral.net by tmoss
great website for wiring and some other info

The 4 cylinder k member will work . you just need to gring off the 4 cylinder motor mounts

Hi, Tony here. I've got a 93 LX 4 cylinder notchback. I want a 5.0 but I don't know where to start. I read some of the posts, but for a beginner like me, a lot of these words are foreign and need to be broken down for me to understand. 1st question is, is it cheaper to do the swap or just buy a factory 5.0? Assuming it's cheaper / better to DIY, what is the absolute 1st thing I need to do? While I'm operating the 4 cylinder, can I get new muffler like Flowmasters?
Thanks,
Tony

hey dude i'm doing the 4 to 8 swap my self the decision to by a factory 5.0 or to do the swap is going to be a mater of preference buying a factory 5.0 has its merits but finding one in good shape is getting harder doing the swap yourself will be a challenge and depending on how you go about it it could very well end up costing more than buying a factory v-8 and depending on your level of experiance could be quit challenging to do correctly(not trying to discurage you but be sure you can do this before you start)
as to what you can start doing before you actually swap the engine you can do the rear end, brakes, exhaust, subframe conectors, springs/suspension
so far i have a BBK off road h-pipe and flowmaster catback (yes it is hooked up and sounds great) tomarrow i'm having subframe connectors welded in the plane is to do everything needed for the v-8 before i have put the engine in

I just bought a '86 LX notch with no motor or tranny. The car was 4cyl./5 speed car.My plans are to swap a 400+Hp 351W with a C4 tranny (that currently resides in my 1969 Ford F-100) into the '86 "stang. My question is. What tranny cross member with work with a C4? The car will be strictly drag strip only. I have read this intire thread on swapping a 4cyl to V8 and I have learned that I can use the original K-member and front springs. I also read that the rack and pinion steering are different between the 4 & 8 cyl cars. I will not need and don't want power steering on the car. How can the power rack and pinion steering be converted to non-power steering?

I coverted a 83' 4 banger to a 5.0l. It wasn't to bad at all. I used a 85' T'bird 5.0 as a doner car. But I turned it into a Carburated version. The springs and rearend worked out fine as far as suspension was concerned, since they are basicly the same except for wheel base of the T'bird. I used the motor mounts from the bird and bolted them in place in the stang. the nice thing about using a stang this old is I got to use the dura spark ignition box from the bird. I swapped the stock intake for an edelbrock performer intake and holley 650 cfm carb. with BBK shorty headers, and performer rpm cam. all for less than $1500.00. I hope somebody can use this info.

My car was an original 4 cyl...Its a 1990 LX. My dad put a 5.0 in it and it runs decently.But as I am never satisfied with it, I want it to be faster

I don't think that 5 gear rom the F150 is going to work for you.

I'm doing a 4 cyl to 5.0 swap and i'm having wiring problems. The engine,computer,and engine wiring harness is from a 90.The 4 cyl car is a 93 i'm not getting power to the fuel pump or coil, do i need a main harness from another year car, if so what year, or is there a way around having to put in a new harness. Any input would be helpful if not i might throw a match to it...

You need a 92-93 harness. Or swap out the dash harness with a 90.

If you had a factory wire diagram you could move the wires you need to move, but that is a major pain. And, you better know what you are doing!

hey guys
new to the site and needing some help.picked up some one elses project and im trying to see what i need to do. got an 89 lx(4cyl,5spd)that has an 88 t-bird 5.0/auto sitting in it. need to know what i need to do to get her running????? the guy i got it from says i neede a ecm or ecu he wasnt sure said they forgot to get it out of t-bird so i guess thats where ill start...
p.s. not trying to hijack this thread thanks

you don't need to worry about hijacking this thread its 3 years old at this point. I have been building a kit car using a 1988 5.0 speed dennsity donor subsequently I converted to an 89 mass air EEC-IV. Then yesterday I got all of the mounting brackets from a Lincoln to swap alternator and AC compressor to the opposite side. So, I can tell you there are infinate possibilities! That being said if you put a T-bird motor in your stang you will do better to get the correct T-bird EEC-IV computer and harness. Then you will need a real good wiring diagram! The T-bird harness will fit the motor fine but will be different from the motor to the car and will requires a lot of splices. A 5.0 HO mustang motor that is the same year as your Stang is the easiest choice but these motors sell fast and $$$$. An easier choice is a carburetted 302. You can spend all your money and energy making mechanical upgrades. Hotter cams, bigger brakes, 6 speed tranny.These are much more fun that spending a lot of time and energy learning how a TFI distributer works.

www.fordfuelinjection.com is a treasure trove of EEC informmation. They list most of the EEC-IV computers. You need a speed density computer for T-bird with an automatic transmission. Once you find out exactly which model computer you need E-bay is a good inexpensive source. The speed density computers go for $10-20. So you are lucky.
