1991 Nissan 300ZX Coupe 2 Seater Twin turbo 3.0 ltr V6

Summary:

The 300zx Twin Turbo has all the elements of a true super car and has yet to be outdone

Faults:

All of the few things that have needed replacement are what I consider general maintainence.

The oil pressure sensor, temperature sensor, and radiator overflow needed replacing. The total cost of those items was under $150.00.

The tension rods also showed heavy wear and were replaced as well as some coolant system hoses. I went aftermarket and do not have the costs for those, but it would be $250-$350 installed. The motor is from a different model and only has 60,000 miles so the turbos and injectors aren't applicable to the chassis mileage. The previous owner did have to rebuild the turbos for an unknown reason, which was over $2,000.

General Comments:

Within reason, the car is fast as any car made today on the straights or turns. Yet it is a decade older.

One of the most beautiful cars ever constructed, and it gets attention from the right people every day.

Very high performance potential. You can reach 400 rear wheel horsepower with about $1,800 on a twin turbo model if you install the parts yourself, and up to 600 rear wheel horsepower on the stock motor.

Potentially one of the worst financial decisions you can make. Only about 17 mpg and you can dump $10,000 easily into the car on maintenance if you don't know what you are doing.

Also one of the greatest buys in history. I bought my car cash for under 8,000, added about $1200 in performance modifications, and can go 180 miles per hour if I got the urge without much trouble.

Do not buy a 300zx without service records, especially of the 60k interval maintenances which are crucial to the motor's life and about $1,000.

Lastly, if you decide to buy one of these rare jewels, take good care of it and it will take good care of you! These are very reliable super cars if you do the maintenance at the correct intervals.

Would you buy another car from this manufacturer? Yes

Summary:

High performance and high cost

Faults:

I recently bought a 5spd non turbo 300ZX, and I'm getting really bad gas mileage. I know that the 300zx isn't known for its fuel economy, but this is crazy. I'm getting about 13 in town and 18 on highways. Would someone let me know how their gas mileage is. Thanks, Dave (sirdave4@hotmail.com)

General Comments:

Does anybody know how to run the diag on the car (ODBE). Thanks Dave.

I had the same problem when I first bought mine, however when I replaced the exhaust system (full cat-back) it helped a bit. I was also told that replacing the spark plugs/wires and getting a fuel system cleaning would help, as they are old cars.

I have a 1991 300ZX TT and get around 15 mpg in town and up to 22 mpg on the highway when I drive it extremely conservatively. When I'm rodding it around it slips to 12 mpg and 16mpg. The 300ZX TT is a step below an all out racecar. It was designed for performance, not an economical commute.

1991 Nissan 300ZX GS-N/A 3.0 Liter V6

Summary:

Amazing Overall

Faults:

There's a distinct fuel smell whenever entering or around the car.

The Bose system head unit and six-CD changer broke 3 days after I bought it. The radio only played.

The Bose system was a difficult challenge to replace. Costly as well, both ways. Either to replace the stock components or to completely replace it.

Spark plugs take about an hour and a half to replace.

Only takes premium gas- very expensive two months ago.

Rear-wheel drive is going to suck in the winter.

Repairs and maintenance for these are a touch expensive though (sixty dollars for spark plugs!?)

General Comments:

The car is awesome, from the interior to the exterior.

The interior puts almost all of the car's controls at the driver's fingertips- Air conditioning and heat, wipers, hazards, almost everything, but it doesn't seem cluttered.

If you want to meet people, buy this car. Everyone who owns one or who has owned one or wants to own one will talk to you. I've met at least fifty people just because of my car. They're a lot more rare than your average mustang, so there's a lot more respect and pride that goes along with it.

I love the response that everything has. Push the gas, instant-response. The brake, immediate response. Amazing.

You won't ever fall out of love for this car.

I have a '92 2+2 manual and I can relate to most of the comments made by Steven (thankfully I haven't had to deal with Bose problems as yet).

The main problem right now is lousy gas mileage, about 12 mpg and getting worse. I replaced the plugs today, (only 20 bucks for platinum tipped Bosch) but the rough idle continues, as I'm sure will the bad gas mileage. All the old plugs looked OK, but I cylinder #3 looked a bit rich.

Tried replacing the air filters about a month ago and the gas consumption seemed to get worse. I noticed that the inside of the air intake plenum was wet, with gas I assume, and it was almost a day since the car was run.

I thought that the problem might be faulty injectors, but how would this get gas up in the plenum, and why would it still be wet?

Does anyone have any ideas???

Thanks Kib.

I will try to ascertain whether the fuel regulator is to blame. Since posting my comment in December, the car is running a lot better, the idle is smooth as glass at 1,000 RPM, but the gas mileage average is still averaging only about 12 MPG.

I appreciate your suggestion and will hope for the best.

An idea for to get rid of the fuel smell from your car is to get a #3 philips screw driver and tighten every screw you can find under the hood. It's a really simple suggestion, but it seemed to work for me.

I had similar rough idling and fuel smell problems. Found that a faulty sensor was telling the processor that the engine was always cold and so sending to much fuel (as in a cold starting situation). Cheap fix to change out the sensor.
