Yes. A mkiii is going to be between 23 and 29 years old. Aide from the obvious head gasket issue, there are other small issues that are likely to nickel and dime you to death. Parts are not as readily available as you might hope them to be. But if you like working on cars, it can be done. I have daily driven mine at various times. One of those times was in the winter. Ill say it right now. Summer tires in the snow meant getting to work late sometimes. Ive also daily driven it in the summer with the ac broken. That sucks too, as i have black vinyl seats.

Thats my experience at least.

In regards to the 7M:
The headgaskets have a known problem. They are under-torqued from the factory, so blowing HGs (headgaksets) is very common. The easiest, simplest way to resolve the problem is to replace it with an OEM Toyota HG, and use ARP head studs instead of factory head bolts. Torque them to 75 ft-lbs instead of the 54 ft-lbs specified in the factory service manual.

Other than the HG problem, most problems are primarily due to the cars age (23-29 years old), and the fact that most of them have been modified/abused a great deal.

Pretty much any rubber part in the engine bay will need to be replaced in the engine bay if it's original, expect oil leaks and various other small problems. Make sure the cooling system has good, clean, quality coolant in it. If the car has been modified, the turbo's lifespan is probably significantly reduced. Underhood wiring (if original) is probably very crispy and weak. If the wiring is modified expect it to be worse.

That $1700 car will cost more in the long run than a nice clean car to start with. IMO You must be looking at different body picks than I see. If they look bad in pics just wait to see in person. Cars that look good can still be bad in person. You live in Florida, you need ac. Supra's are very hot with out A/C. Driving with no PS is flat out dangerous for street driving. IMO. If you have the money for car and engine work you have the money for a better starting point. Look for clean low mileage stock un modded car IMO.. Good luck.

"I have a 89 supra with the 7m-gte. Im looking to sell or trade for something reliable and mainly 5 speed. The car was rebuilt by last owner with almost everything new. It currently has a vacuum leak problem and it makes the idle rough and jumpy. It has a gt45 turbo with 3.5" fender exit exhaust done by all boost production, stock computer, 440cc injectors, mishimoto fmic (front mount intercooler), mishimoto oil cooler, stage 1 clutch, w58 transmission, an hks bov, kyb struts with h&r lowering springs, and 18x9.5 wheels

The cons to the car is it has an oil leak from the oil pan gasket, and leaks slightly from the tail of the tranny

Other than that the car is solid on 8 psi of boost... smokes slightly from turbo

It is fs or ft feel free to call or text.. thank you "

This part of the ad may say it all as far as I'm concerned, as the owner pretty much admits up front that this vehicle is something less than reasonably reliable. That's most assuredly not where someone new to Supra's will want to start their relationship with one (I can tell you that from personal experience with one). I myself would definitely keep looking for something a little closer to stock, well cared for, and less likely to have to be figured out just to know exactly what the past owners have done to the wiring and other systems. They're out there, just be patient to find the right one and choose wisely.

Supra's are like redheads... they can be fun and exciting, but my o' my they tend to be high maintenance.

well there are other mk3s for sale around me but some have a 1j, 2j or are non turbo. but maybe a non turbo model might be good for me to start off in and if i still want a turbo i could always build the motor.

Like I suggested, just take your time and do your research before you pull the trigger on one. The good ones are more difficult to find but you'll be much better off in the long run if you don't have to spend half your time and all your cash just repairing what other owners have done. Keep an eye out here and on some other forums for a decent quality Supra, and welcome to our collective insanity.

Save your money until you have enough to buy quality. Otherwise you might find yourself chasing a ghost with your head firmly in your hands.

Be patient and buy an unmodded car. I just spent a few weeks with a customers car that he overpaid for because it was modded (turbonetics bolt on turbo, 3 inch exhaust, 550s, etc). I had to put an engine and harness in it, as well as clean up no less than 20 different little issues that one of the previous owners caused with the mods they "installed". Bottom line is, the poor guy is into a $2500-3000 car for over 5K now.

The stock 1jzgte makes 280hp at the crank. Stock 1uzfe makes 250-260 depending on year. The main difference is that the 1uz makes 200lb-ft of its 260lb-ft of torque at 900ish rpm.

Both engines are extremely well built. I have seen 1uz motors with over 500k on them. My SC400 has almost 300k on it and runs like it's new.

Replacement 1uz parts and complete engines are readily available. You rarely find bad ones in junkyards. That being said, they don't have nearly the aftermarket support that the JZ has.

On the flip side, 1jz engines and parts aren't as readily available having never been produced for the us market. Their power potential is much higher due the insane aftermarket support.

The 1uz has 3 generations: ( years vary by car)

1st gen - 90 to 95/96 250hp
2nd gen - 95/96 to 97 260hp
3rd gen - 98 to 00 290hp (VVTi)

As far as the jz engines, the 1jz went VVTi in the mid 90s, and iirc went single turbo with the vvti change. The 2jz went VVTi in 97ish, but kept its twin turbo setup. Unlike the 1uz, the jz VVTi engines pretty much keep the same power level as their non VVTi counterpart. I welcome a jz expert to check my facts, I'm basing my jz info off my terrible memory.

Are you very mechanically inclined? Do you want boost? We need more info about your goals and budget.

MKIII's are very cool cars, double wishbone suspension, disc brakes all around, power everything. Have the unique 80's look. I love mine but be prepared to do some wrenching/spending regardless of the engine choice.

i do want boost and i would like to rebuild a 7m from the ground up and would like to get it pushing 500-550hp with upgraded drive train. I do plan on going to school for mechanics within the year so i want a mk3 just to have as a DD from home and school then after school was done build it up, but after engine was all done then id want to work on other areas of the car. But i want to keep it a 7m cause i figured that parts for the 1jz and 2jz were more expense to get.

Honestly speaking, I have an '89 that I got years ago. It was bone stock and was in great condition. I daily drove it for a whole year when I got it then I wrecked it being a jackass. Fixed it drove it again and drove it for another year and again like a jackass, spun a bearing. Point is that I wasn't ready to own a MKIII. I can honestly say that I wasn't ready to own this car when I had it. It is not a car to be taken lightly. Now that a few years have past, and the car has sat, my "goals" of 500+ hp that I wanted back then have come down to a realistic stock to 320 hp. Why? Because I'm not sure I want to set speed records or hp records. I want to enjoy the car for what it is. An 80's Japanese GT touring car. In my most honest opinion, buy a stock MKIII and get a feel for it, see if you enjoy it and build your relationship with it. Never buy someone else's pipe dream. As you will never know what all has been done to it. Don't let someone else's negative experience ruin your own.

Well the mechanics school I plan on going to will take me 2 years to complete so I planned on keeping it stock for that long will be good.

Every car you have listed is somebodies problem car they cannot fix themselves. Fixing a problematic project car is very expensive and a waste of time. I think everyone has stated the same thing. Start with a bone stock, well taken care of car. There are nice clean cars out there. Nice paint and body, clean interior and stock powertrain. It takes time to find the right car. Autotrader.com has a super clean 89' with less than 80k miles all stock with clean leather interior. Asking about $8000. Only bad thing it its an auto. The nicer car you start with the cheaper it will be in the long run. IMO. Don't start with some car the previous owner can not daily drive. An important question that you need to ask when looking at a cars. " Is there anything keeping this car from being able to be driven everyday?" IMO good luck. BTW any supra you get should be your second car. Meaning you have a reliable DD like a camry corolla or Honda. IMO

It can be done, but you'll have to wait a while for that price. 2 years ago i paid $3800 for my 1990 turbo 5 speed, 90,000 miles. Seller told me it was stock, except for the k&n cone filter, the exhaust, and the wheels. 10,000 miles later i blew the headgasket, tore the top end down, and i discovered the previous owner was being honest when i asked about the headgasket being replaced. He said "no". A few of the head bolts were only finger tight, as were some intake bolts. There was a stock gasket and a shim underneath. Also the timing cover was higher than the deck. Judging by the lack of carbon in the combustion chambers, id say it was done probably exactly 10,000 miles ago. Just one of those "you get what you paid for" deals. I also noticed about 6 months after i got it it has been repainted before, though i cant tell how long ago. I just wish they would have sprayed some clear as well.

Use part of that budget and buy a reliable Civic or something cheap as a daily(unless you already have one) then the rest for the MKIII project. IMO

The last supra I bought took looking at 15 plus cars 4 different states and took two years to find it. I am very happy I waited. Don't get a hurry.

So as i looked around today for a mk3 i came upon this one. "Up for sale is original 7m 1991 Toyota supra. One owner bought brand new from Toyota. Original motor and transmission, runs and drives, clean tile, clean history. Has ARP head studs, HKS head gasket, HKS turbo, HKS FCD, exhaust and down pipe. Runs strong!!!"

I would have a hard time dealing with the spoiler. The seat covers and dash covers are covering up something. He drives right over top of a parking curb? Looks like car started of as a NA car. I doubt that someone would take off the rear spoiler and fill and paint the holes to do it. IMO

Think super51fan is right about it being N/A originally. Make sure its an R154 if you decide to buy. Even then I would lowball
