1986 Toyota MR2 Base 1.6 4AGE

Summary:

A lovely car, a blast to drive, and inexpensive to obtain and maintain

Faults:

I bought the car with a bad alternator. I have gone through two more since then, but I believe that to be the fault of the alternator remanufacturing company, rather than the car.

Speedometer was inop when I bought the car. The fault was in a broken speedometer cable, which was fairly easy to replace, if somewhat time-consuming.

The driver's side power window was nonfunctional when I bought the car. I determined the problem to be in the motor, and was able to replace the faulty motor with an Ebay part for only $45 or so. Replacement was not at all difficult with hands small enough to fit inside the door panel.

The original leather driver's seat has worn badly in the car's seventeen-year life. I plan to recover the seat. Also, the leather cover on the steering wheel has worn very badly, and the shifter boot was torn when I bought the car. Replacing the shifter boot was very easy and quite inexpensive.

The radio aerial was eaten by a low tree in my yard. Replacement was somewhat difficult, but the factory antenna, with cable, was very inexpensive.

The factory stereo would not output to the left channel while the tape player was in use. I replaced the stereo unit with a CD/MP3 player and am very happy with it now. Replacement was the fastest and easiest of all of the cars I have installed stereos in.

The original dash speakers had begun to crackle by the time I took ownership of the car.

The synchronizers have begun to wear, especially in second, third and fifth gears. The gearbox has never been rebuilt. I will do this myself within six months, at the same time that I replace the clutch. The gearbox has an audible whine in the very top of third gear.

The original muffler had rusted through and developed a hole the size of a golf ball. My car sounded like a Honda until I had the muffler replaced last month, at a very reasonable cost for such a large, oddly shaped muffler as the MR2's.

The props for both the engine cover and the front boot have broken their clips, and now rattle incessantly when driving at any speed. They are not so loud as to be intolerable, but the rattles are always present and irritating at times.

Both rear strut cartridges have blown their seals, causing serious wheel-hop upon breaking a tire loose. Taking a corner too fast, while accelerating, can cause the car to shudder violently until the driver lets off the accelerator and regains traction.

The car's paint has stood the years well, but the black plastic trim on the sail panels has faded badly. Also, each of their retainers has either cracked or will very soon. These trim parts are very rare, and will not be cheap to replace.

The original weatherstripping still seals well. My car has no leaks, around the windows, the doors or the sunroof.

Air conditioning does not cool as well as it should. I will be converting to R-134a within one year, and will solve any problems at that time.

The clutch has begun to slip more than I would like, under hard acceleration in gears. This is a normal wear issue, but needs to be replaced soon.

The cabin trunk-release cable has been broken since before I bought the car. Replacement will be difficult as it is routed through the firewall into the engine bay, and then out into the trunk. I will wait until I replace the clutch and engine before I attempt to install a new trunk-release cable.

General Comments:

I love this car. I love everything about it. Each time I drive it, I find some spectacular reason to praise Toyota's brilliant engineering, and each time I walk by the car I admire its unique styling.

In its day, the MR2 truly was a thing all its own. It had a rev-happy motor with variable intake timing, a very nice interior with supremely comfortable sport seats, and an extremely reliable, economical powertrain - especially for a sports car. It also has a very low curb weight, around 2300lbs, which obviously aids in its acceleration and handling; but the car has proven its ability to protect its passengers in collisions.

I have a very few complaints about this car.

First, while the MR2 is powerful enough to be a ton of fun to drive, it is not quite powerful enough to be competitive in autocross or track racing. Fortunately, any of Toyota's marvelous 4AG series will fit into the MR2, including the later Supercharger engine, the famous twenty-valve engine with independent throttle bodies, or an 11,000rpm Formula Atlantic engine. A later MR2 Turbo motor, the 3S-GTE, will even fit with a little work and a big shoehorn :)

Second, sound quality is not as good as I would like. The car has only three speakers total: two set into the dash, and one subwoofer underneath the driver's seat. Replacing the factory speakers and deck with quality aftermarket units has helped a great deal, but I would like clearer sound.

Since I paid only US$1280 for this car, I did not expect what it has given me. I have had from it more than eight months of nearly unbroken service, getting better than thirty miles to the gallon, on occasion. It is a very forgiving car up to its limit, but can snap around when traction is compromised, due to its engine configuration. It has lived through my first few months of driving with a standard transmission, and it has no problems whatsoever with even heavy rain.

Would you buy another car from this manufacturer? Yes

These 1.6L fours do not have variable valve timing in the truest sense. It is really just a dual runner control for the intake manifold. Huge difference which could be misleading.

I recently purchased a MR2 and proceeded to strip the interior, Weld in a roll cage and swap out the previous engine which was bagged and replaced it with a Corolla engine. I must say that after coming in 2nd and 3rd against much more powerful Subaru's and various other rally spec cars in amatuer rally racing, this little car hauls and handles beautifully. If you should ever get the chance enter in a rally and turn some heads.

My speedometer cable just broke and I can't get it out. Are there two cables running from the motor to the dash? Also are there any tricks to replacing it. I couldn't pull out the broken cable, it's stuck.

1986 Toyota MR2 1.6 Liter 16v Dual Overhead Cams

Summary:

I love it!

Faults:

While driving down the road one day, a loud screech arose from the engine. The first thing that crossed my mind was that it came from the alternator. The second thing to cross my mind was that the bearing froze up and that the screech was the belt slipping against the pulley. After some investigation, I found that the bottom alternator bolt had vibrated loose, a simple $1.25 nut-and-bolt replacement.

While driving on another day, all of the sudden I hear this whining sound. It sounded like a flat tire rubbing the inner wheel well. It turns out that only one of the two upper engine mount bolts had a nut on it. All this pressure on a single bolt caused it to snap and my engine dropped about 5-7 inches down. It's fall was broken by my transmission mount and drive axles. The whine I heard was the A/C compressor pulley rubbing the bottom plastic engine cover.

Both of these problems occurred do to improper care taken during a previous engine swap.

General Comments:

This car is seriously quick and handles like it's on rails. I took that line from the survey example, but in my case it applies. The car's mid-engine layout and suspension design by Lotus give the car a "glued" feeling. Flat road? Reverse bank? No problem!

And as far as being seriously quick, its 1.6 liter with dual cams and 16 valves produces a healthy 120 horsepower that pushes me to 60 in about 8.5 seconds. Not bad for a 16 year old 4 banger. I'm sure the engine swap has something to do with it, especially since the stock block was swapped with a newer model. But with the new engine, my specs are still stock. A real Honda eater...

I'm a true believer of the MR2. I bought mine in Phoenix Az for 1200. Not in the greatest of all body shape, but the engine and transmission are in great working order. The platinum spark plugs give an even spark and burn. The first to go wrong on my MR2 is the speedometer and fuel pump, but with a little TLC this car is a joy to ride and will last forever.

I would just like to say that I own a 1986 MR2 and I absolutely love it. I bought it off a collector in La Jolla, CA. He had only put 38,000 miles on it in 19 years. I have had only two problems with this vehicle thus far. Firstly, I have had to re-wire the tail lights. After the re-wire and replacement of the bulbs, everything seems to be okay. Secondly, I noticed that when I put it into gear, the car would jolt slightly. So, I inspected the motor mounts. Sure enough, the mounts are on their last miles. I went to an auto parts dealer and ordered some new mounts (front and rear--the transmission mount seems to be unavailable). Plus, it turns out that I paid too much for those mounts. Anyhow, if you own or are buying an MR2, check those mounts.
