Hi guru's,

 

I have just aquired a '90 300zx Manual (not turbo) and had high eexpectations. I have never owned a jap sports car before and fell in love when i saw it, so I bought with my heart not my head.

 

There is an intermittent vibration when I drive over 80kph (I will have to get the speedo changed as a priority). It's not always there, but most of the time it feels like its going to shake the car to bits!

 

The car is leaking either brake or power steering fluid from just behind the passenger side front wheel.

 

There is a really loud nise from the power steering pump when turning the wheel at standstill or low speed and the steering is really heavy at low speed.

 

Lastly, as an import it has been restricted to 115MPH but even though the engin is smooth, it doesn't feel like a 220bhp car. Will derestricting it liven up all the performance?

 

Have I bought a dog? can these things be fixed cheaply? should I cut my losses or stick with it?

 

Cheers

 

Stevie

OK - After going through the millions of posts it looks like the prop bearing is the cause of the vibration, are there any 300ZX specialists near Hertfordshire?

 

Still not found any clues about the steering or de-restriction problems, (can I turn off the beep when I go iver 60mph?)

Last thing... Honest!

 

Even the the clutch is good and the manual gearbox works fine, there is an awfull lot of movement from the gear lever in each gear (like stirring a bucket of bricks instead of slotting neatly into each gear!)

 

Any Ideas?

Have you had the wheel balance checked?

Sounds like the selector shaft maybe worn in the gearbox

Have you checked power steering fluid level?

Did you pay alot for the car?

The wobbly gear stick is probably the gear stick bushings cost about a fiver from Nissan, but are a pain to change. :)

 

Behind the passenger side wheel area is a joint in the power steering pipe which goes from fleible to metal pipe, it may well be that thats leaking. Low fluid, or someone who has just topped it up without bleeding the system would cause it to whine at full lock.

 

Truth is, it is not a 220bhp car. the car was advertised as 220 bhp at the crank, not the wheels, you will probably be running about 180 at the wheels. De-restriction, an induction kit and a nice pipe and a chip will make it feel 10 times better and sound about a hundred times better. You can tune it further than that but its a good start.

 

The chime is a silly box behind the clocks, easy to remove, just unplug and play :) Try ztech in the traders forum for a specialist near Herts. :)

OK Guys now I'm worried, I topped up the power steering fluid and the noise has gon (expected) but the leak has stopped?

 

I didnt pay anything for the car... I swapped it for a Reg Mondeo diesel. Not knowing anything about these cars I couldn't say how much it is worth (1990 manual Non turbo, 17" wheels, Cloth trim, no cruise but aircon and it's a T-bar roof 2+2 import 99K km's) So if anyone can give me an idea, I would be greatfull...

 

The MOT runs out in a month, when I guess I will have to get the Cambelt service done at the same time, but can you tell me if it is safe to leave the propshaft bearing bearing until then?

 

Oh and yet more fun, went to the pub last night and left the windows down and roof off, when I came back the passenger window doesnt work. I looked through the posts and found a way to get the window up again by wireing the window motor directly to the battery (thanks again guys)...

 

All points to the question "Have I bought a Dog?"
