Question 1993 4 Cyl Swap

If I have a 1985 5.0 Mustang (5 Speed) already.

How hard would it be to swap the motor/tranny into a 1993 4 Cyl mustang (Automatic) ?

Re: 1993 4 Cyl Swap

do you have both whole cars?
if you do it's just a matter of just ripping the drivetrains out of both cars and installing it into the '83. it's not that big of a job. no custom work needs to be done. it will all bolt right up

Re: 1993 4 Cyl Swap

Well I was looking to buy the 4 cylinder.

I have the 85 mustang, but it has NO interior or wiring harness at all.

There's a little more to it than that. The '85 is carbed and the '86 and later 5.0s are not. You will have to decide if you want to go to an EFI set-up or if you want to stick with the carb. Either way there will be some wiring issues to consider.

You will also want to upgrade the brakes and suspension. The four cylinder brakes barely cut it for the four cylinder cars. They really can't handle the extra weight from the V8. You will also need the brake lines from the V8 car if you do decide to upgrade the brakes. Many of the suspension parts are also different between the V8 and four cylinder cars. The main one I can think of being the front springs, which again are not designed to support the weight of the V8.

There are probably tons of other little things I am forgetting too. But it's really not all that bad because everything does bolt right up into place. It's just a matter of figuring out what all parts you need and swapping them over.

Do you guys think a 93 4 Cylinder in CLEAN condition 53,000 miles is worth $800 ?

Probably way more than you want to pay. You would end up better off selling the car and buying a later model 5.0.

May I ask why it is that you want to put the drivetrain from the '85 in a four cylinder car to begin with? Is there something wrong with the body/frame of the '85?

There in no interior at all in the 5.0, or wiring harness, or lights, or anything.

Well, your other option would be to reverse your thinking and swap all that stuff from the four banger over to the 5.0.

The 5.0 also has rust, allot of it, roof, floor ect.

And that would be allot harder I think.

Plus the 4 banger is a notch, were the 5.0 is a hatch.

From what I was reading and people were saying... the conversion is not that hard.. I got both cars.

Re: 1993 4 Cyl Swap

my '92 coupe is a conversion. dont forget about swapping out the swaybar in the front and adding a sway bar for the rear. it's not the hardest thing in the world, but u need a fair bit of patience. u definatley dont wanna pay someone to do it for you, unless u find an ase certified stangbanger crackhead dat will work for damn cheap...lol.

if u can keep the cost down. it took me 30 days to build mine. but mine is efi. the mounts are the same. make sure you get some wiring diagrams, they are very helpful. u get to know alot about the car when u do it that way...lol.

Re: 1993 4 Cyl Swap

I may do a 5.0 swap in my 93 4 cyl down the road, not sure yet. I am doing a 460 swap into my 81 4 cyl hatch though in the mean time.

Mine will be carbed and will be around 545 ci when all is said and done. IT will fit no problem, there's lots of room under there for it. They have complete swap kits with k-member and headers for the swap. Should be pretty straight forward.

No, the fenders stay intact, the fire wall stays intact. It's a direct swap and can even fit under the stock hood if you by the k-member spacers or the drop k-member.

The trans that will get bolted to it will either be a lentech auto or a T56...many run the C6 or an autoglide.

The only cutting/welding that will be going on in my engine bay will be plugging excess holes.

Re: 1993 4 Cyl Swap

did you ever go through with the swap?

the 85 5.0 suspension is the same as the 93's 4 banger suspension. not until 87 did the v8's get a better suspension,bigger front brakes, so the only good donor would have to be a 87-93 v8 car. plus brakes lines are in different spots and fuel lines are different.

mrlight460, could u share some info, thinking of doing this to the 87 coupe I just picked up this summer

my 92 coupe is a conversion. as far as your 87 goes. springs, front sway bar, add a rear sway bar, fronts breaks, rear end depending on your hp level, a 7.5 will hold up to more than wut most ppl think. but u will definatley have to addresse the trac loc..or lack of actually. unbolt fuel line from body and bend over to other side. i push'n over 400hp. i can honestly say that u can drive on the 4cyl. brakes..normal driving only. they are a challenge at 140+ though. i have been using the 7.5 with frpp trac-loc for 3yrs and no problems, however keep in mind my car is racing aod equiped, not t-5. it's time consuming but not rocket science, i hope some of this helped.

Sure... I will start at the front and work my way back.

Cooling:
I bought a generic aluminum radiator and mounted a 16" Be-Cool radiator with the push through plastic straps. I used a Meziere electric water pump.

Electrical (alternator):
I kept the factory alternator (6 rib pulley) for simplicity reasons and mounted it to the front motor plate. I also used the factory 5.0L crank pulley on the 460 so the alternator still turns the same speed. Since this is the only thing I need to turn I went to advance auto parts and bought the shortest 6 rib belt. I believe it is 30" so I used this to position my alternator.

Electrical (gauges and other):
I did TONS of research online so I could get all of the factory gauges working. Let me know if you need any of this documentation.

Mounting Engine:
D&D kit (motor plates w/ brackets, oil pan, pickup, dipstick, headers)

Front suspension:
The engine will go in with the factory K member but I recommend some type of tubular unit. I went with the UPR chrome moly and coil over conversion. I cut the tabs off for motor mounts so my headers could drop lower. I did not use the available spacers to drop the K member below factory (no real reason other than I didnt know about them). When bolting the front plate to the brackets I actually laid the oil pan on my rack to get it as low as possible (I used a piece of wood about 1/4" thick as a spacer). If you do this be sure your rack is level (parallel with the K member as this will determine how level your engine is). You can get a manual rack from autozone for cheap. I did buy the flaming river shaft to replace the stock rag joint. I believe this is necessary to clear the headers but I never tried the stock unit.

Trans, bell, mount, and driveshaft:
I used a PA C4 trans with a bulletproof bell (the bell I needed had to be modified to clear the headers). A factory crossmember from an 84 gt will work with the C4 (I tried an 86 and 93 crossmember but they will NOT work). If you get the right mount it will force you to place the trans in the right position to be able to use the factory driveshaft. DO NOT go through the pain of trying to use any factory C4/460 dipstick tubes with this header/bell combo. Just save up and get the Lokar flexible one. You will thank me in the future.

Please let me know if you need more information. I am sorry it took so long to respond but I've been really busy.
