My wife is wanting to buy an 88-93 Mustang 5.0.  Is there any common issues I should look for before buying one?

UPDATE: bought the 90 GT today. Needs tires, paint (it's the ultra blue with gray bottom) and the seats need to be redone. Runs great, body and doors all line up fine, no rust on the shock towers or torque boxes (no cracks either). Has 144k miles, I bought it for $1800


Here's a pic of when I picked it up (new mustang pony wheels and new tires will be here next week):




At home in the garage




Today I completely stripped the interior. It's getting the seats redone, new carpet, repainting all interior trim, etc.  Here's a quick pic today after taking it all apart:

basically as close to stock as you can get is better.

Chances might be low that someone screwed with it then

Love them

Why isn't '87 in the running? That was the 1st year of the ground effects that those other years had.

^^^^^^^^ '87 was the switch to the new body style. 85-86 had their own and 79-84 are relative.

Avoid anything with sunroof, T-tops or Convertible. I had an '86 GT with sunroof, nothing but issues with it. Otherwise, try to find one stock like mentioned. Look for usual things ppl do to them (headers, intake, cold air intake, subframe supports, exhaust, etc.)

Cracking in the floor pan under the driver's seat if it had some fat person driving it.

Wife wants a convertible.  It will live most of its life in the garage parked next my 62' Fairlane.  I've found a couple close to me that were all bone stock, no mods done at all.  They are around the $3-4k range, not sure that's good or not

You pretty much need to toss out NADA/KBB on value when it comes to older, your going to pay for condition and mileages and maintance. Id pay 4k for a decent GT that was stock.

I had a 7up edition 1990 convertible for many years. The only issue I had, and I think it is common to the motor, was a rear main seal leak. It had 2 or 3 recalls for electrical stuff that were handled easily by the dealer. I liked it a lot.

sorry Common problems

broken ash tray door
Bent driver side seat ( leaning back and into center of car)

Check floor pans by firewall, seat mounting and rear section around gas tank.

Sunroofs have been know to leak, Good seals are available. Check drain tubes that go behind quarter windows
also quarter window trim is normally junked. Replacements are an option.

My 91 has 36k original miles on it

get a MAF one, 89-93.  It will make upgrades easier in the future. Check torque boxes for cracks, especially on convertibles.  If you find one with a working ashtray, buy it.  Those things are always broken


My baby from HS.  My dad bought it new in '91.  I bought it from him and did a .030" bore, H/C/I, exhaust, Tremec Trans, 150 shot, etc.  My buddy totaled it, and he wasn't even supposed to drive it.


It was 100% stock appearance, except it was lowered 1", rode on some fat Mickey Thompson street radials and had a Cobra rear bumper. I surprised more than a few LS1s with the old purge switch and remote bottle opener...

The one I'm looking at (1990 Mustang GT two tone blue and gray) is owned by a 65 year old man.  He's the second owner of it, and has had it for the last 20 years.  It's got 144k miles on it. He had it repainted about 10 years ago, the paint still looks good for its age.  He's asking 3k for it

What year?  5 SPD?  At $3k if its pretty clean I'd buy it in a heartbeat!

Beat me with an edit.  Go buy it now...

Edit:
Don't be surprised if the rear windows don't work.  They aren't THAT hard to replace the regulators, but they do go bad often. You can help this by only rolling up the windows after the top is up. The top slamming onto the raised rear windows caused premature wear on the regulators.

You can fix the ashtray door, you know.

ETA: Black seats are also made out of gold. My driver's seat is broken, and its almost more cost effective to grab a discarded recaro out of an Evo than an original black sport seat.

Man they are SLOOOW with an auto, especially being a heavy bodied 'vert.  The AOD in those cars was particularly lack luster, but luckily the aftermarket is flooded with shift kits and parts for those cars.   The top motor is going out, and they aren't the worst to replace, but they die a loooooong death.  When mine started going out I just held the button for the top and reached back with my other arm to help the top come forward.  It will probably be fine for a few years.

Do the usual rundown for used car stuff, check the shocks with a bounce test, check the vac lines, and the filters.  Wiggle the wheels in and out and side to side looking for wheel bearing slop, bad tie rods, or ball joints.  Push and pull on the rear wheels to check the axle bearings.  In fact, go ahead and crack open the diff as soon as you get it, throw in some 4.10 gears with a rebuilt clutch pack in the differential. Factory were probably 3.31 gear ratio and one wheel peel(clutch diff burned up) was common.

That's I can think of off the top of my head.  It's been almost 10 years since I was really into the 5.0 scene.  Good luck and I'll check back with this thread, but feel free to IM me any questions!

I had an '86 GT as well.     I didn't have any sunroof issues, though. 5-speed manual......man, I do miss that car. I can still remember the badass snarl when you started it up. It was quick as hell for what else was on the road back then, but holy shit those brakes sucked.

Loved the 85 I had, but the t-tops worked better than most shower heads.
Big thing on the fox body is floor pan where the seat bolts in. They are known to tear from metal fatigue.
When looking at one grab the top of the seat and push it around to make sure the floor pan is good

Look at the torque boxes and undercarriage for cracks and breaks.



Convertibles are also susceptible to door sagging of the owners dod not put sub frame connectors on the car.




The rear main seal and head gaskets will weep a bit of oil on higher mileage cars.




The 87-92 models used forfed pistons...the 93 had cast pistons.




The T5 is weak...but easily replaced.




The stock E7TE heads are the biggest restriction to performance on the 5.0...a head swap to anything else will really wake the motor up.

where the rear control arms (4) mount to body.

There were not a lot of other options out there.

My 95 Cobra has a slightly upgraded t5, honestly 330ft/lbs is enough capacity unless you are on sticky tires and drag launching it, and I find no issues with i given I have traction problems even wuth 315 street tires.   It is a nice light trans when it comes to dropping it for rebuild or clutch replacement.    I would sooner do a Gforce T5 upgrade than do a big heavy high rotational loss t56.

I may some day own a Fox body but no way in hell I would have a convertible.   LX notch back coupe for me.   Subframes at a minimum with cobra 5 lug disc brake conversion front and rear.

As others have said, 89-93 for mass air.

Do a head/cam/intake with a tune and be done.

You can swap in a manual transmission without too much trouble if you really want one.  I'm without a 5.0 right now, but I've got my manual trans swap parts tucked away for when I have the garage space again.

If it looks like it has been worked. Check the gaps, 80% of the ones you find will be all twisted up from racing.

Floor boards are a cinch to fix in fox body cars.  Even full on replacement is easy.  

Op there is a lot of good advise.  Definitely avoid sunroof cars. My fb had a factory roof that leaked like crazy.

Factory were probably 3.31 gear ratio and one wheel peel(clutch diff burned up) was common.

That's I can think of off the top of my head.  It's been almost 10 years since I was really into the 5.0 scene.  Good luck and I'll check back with this thread, but feel free to IM me any questions!



There is a fix for lackluster performance.

My wife is wanting to buy an 88-93 Mustang 5.0.  Is there any common issues I should look for before buying one?

Bracing.  Most people don't brace the chassis.  If you're going to make power with a fb car,  you need to have chassis braces,  torquebox reenforcement,  and ideally a good cage to cure chassis flex.

We have no plans to do any crazy mods to it. She just wants a convertible to cruise around town in

Check for...
Check body panels for gaps.  Check torque boxes.  Broken seats,  floor pans,  fuel fill pipe seal,  door hinges and window regulators.  Those are what I can think off off the top of my head.  

The 5.0 engines are usually pretty bullet proof.  Check the oil for anything obvious.   Check the coolant.  Look for oil leaks,  rear main is common.  Drive and make sure the trans shifts and works fine.  Check the trans fluid.  Check suspension and swaybar bushings. Off the top of my head.   The rest is common used car stuff to look over.

Even if you don't plan to beat on the car, I would still install a good set of subframe connectors that include support braces for the front seat mounts.  Convertibles come with additional torque box bracing, but they lack any bracing between the front and rear subframes.  Without the roof structure of the coupe or hatchback the stresses of normal driving will cause a convertible to experience body flex over the years which will lead to problems.

A set of subframe connectors is cheap prevention for multiple problems.

You want 89+ which is mass air. 88 and older is speed density. If you are planning any power adders (turbo, nitrous , supercharger) with the stock bottom end you want 89-92. As 93s have hypertectic* pistons.

ETA maybe its 88 on for mass air. I never kept any of that stuff long enough to remember. Last car had fast injection

Wish they weren't so hard to find around here. I want a notch back which makes it even harder/more expensive.

Also check the vin to see if its a "real" v8 car, not a conversion. The 8th digit will be E for V8 cars (93 cobra is D).

1992 GT is what you want to hunt for.  Last year of forged pistons, the wheel well openings were enlarged on the 1991 and up cars so you have more tire clearance, the T5 world class was being upgraded through several minor revisions, with 1990 being when it was finally upgraded on the books to take more torque.

Good luck finding a lower mileage example with good paint and no dings...they are getting really hard to come by in that condition any more.

Had an 87 GT T-top in high school and it didn't take much to get it to run 13s in the 1/4... loved that car. Wish I had another..
