4 CYL TO 5.0 SWAP???

[j-rock]

Hey guys I'm new here. I have a 1990 4 cyl car and want to swap a 5.0 into it. I just have a couple of questions. I want to stay fuel injected. Do I need to get a 5.0 computer to swap into the car and do I have to change any of the wiring harness. Or does everything just hook right up? I know about the rearend, trans, etc. I just need to know about the 4 cyl computer. I would appreciate any help on this subject. Thanks.

your gonna need a new computer and harness. i think you have to change every harness under the hood. you will want to find it in a car of the same year too. oh, if you can find one use an explerer 5.0 wish i would have
if your going 5spd. a9l is the computer you want

Sounds almost like I should go carbed. Looks like it would be a lot less trouble. Thanks for the input.

its alot of plug and play action.. there is no actually modifying to the harness or body.. everything bolts on and plugs up.. sensors will have to be changed and such but i wouldnt be scared to do it

I have a 5.0 Mustang mag from a coupple years ago and it had the swaps 4 to 8 and 6 to 8 and 5.0 to 5.8.
It told you every thing you need to do and every part number for all the different parts. None of the stuff semed that hard to do with all the pictures they showed it would be very helpfull. If I can find that mag I will send it to you if you want it.

I just done a swap. I had the 5.0 engine and it still cost me $1500 in parts. A donor car is the best way to go about it. The following parts were different in my 93 lx swap.

Motor mounts
Starter
Battery Cables
All brackets
A/C compressor and lines
Coil
Engine computer
Main harness
Engine harness
O2 harness
Front electrical harness can be altered to work
Fuel lines from filter to engine compartment
Cruise control unit
throttle cable
All vacuum lines
H pipe
Crossmember
Cat backs
All exhaust hangers
Rear brake lines
Auto transmission
engine plate
flex plate
torque convertor
shifter
shifter cable
driveshaft
air intake
Fan - 4 cyclinder electric fan is too tight to use
fan thermostat
All cooling hoses
fan belt
speedometer
The 4 cyclinder car has no air pump or related parts will need with the 5.0 to pass emissions testing

I sure I missed a few parts. I started mine three weeks ago and a few odds and ends this weekend, it will be on the road. The engine started right up after the swap with no problems.

That would be awesome if you could. I would really appreciate it. Thanks for all of your help.

I live in Alabama and don't have to worry about emmisions, yet. Guess I'll have to keep my eye out for a donor car. Will the 4 cyl t-5 bolt up to a 5.0 or do I need to get a different bellhousing?

They will bolt up but thier is some bushing or something that is weaker on the 4 cyl one that u should change but I don't think it you half to. My friend is running a 4 cyl tranny in his 5.0 and has had no probs with it so far and he beats on it.

i am curently taking everything from my '86 and putting in a '87 4cyl. (im swaping to carb.) car and i was going to use the '86 dbl. hump crossmember...but to my suprise this car already had one (previously a 2 owner car...and im assuming it came factory)

i just though that i would share that piece of info.

 

[j-rock]

Glad to hear about the tranny bolting up, gotta save a few bucks here and there. The Cobra payment is killing my extra funds.

 

[jstang209]

its easiest if u get a donor car like i did... and if u can turn a wrench then u can do the swap in no time

 

[j-rock]

Thanks for all the help, guess I'll start looking for a donor car.

 

[Modular2v]

i had a speed density 5.0. it would have taken less work for me to stay fuel injected than you and i went carbd if that says anything

 

[j-rock]

Carbed is sounding better to me, instead of trying to find a donor car right now. I could always change it later.
