Hi Ralph, Doc here,
you need to discuss the replacement engine job with the shop doing the switch
and then determine what you also want replaced. With the clutch out (if
it is a stick) pay for a new clutch and then you should not have to pay
for more labor since it is removed with the engine job. The same thing
goes with the timing belt and water pump.
The O2 sensors are in the manifolds and are easy to replace with the engine out. Of course the spark plugs (NGK) only and the spark plug wires should be replaced if they are original.
By the way, looking at the older e-mails I wondered if
you had the reverse light switch replaced yet too?
Another thing that you need to do is at least have the radiator checked,
or replaced, since it will keep your ZX cool in the summer and protect your
engine investment.
I hope that this helps you and others...............

I have a 1990 300ZX NA coupe and have 157,000 miles and will have a remanufactured engine installed, can you tell me what will or will not be added with the new engine. O2 sensors, fuel dampners, plug wires, etc,.
What if anything should be changed while engine is out.
Any help would be appreciated. Please reply to both email addresses.

Hi Ralph, Doc here, since you are back in old Windy, which
was my old stomping grounds from '68-'76 I still don't miss the Weather!
You should be able to get into contact with the Windy City Z Club to find
a reputable repair shop that some of the members can vouch for the quality
and reputation. Keep in touch..........

Thanks for all of your advice. I'll start working on it on my next off days.
Actually I'm in Chicago and the weather could be much better than what it
is. The temp here is in the mid to high 30's. I would prefer it to be in
the 70 - 80 range.
Hey thanks again and I'll try to keep you up-to-date on my progress.

Hello,
I have a 1990 300zx coupe NA 5-SPEED and had my clutch replaced in 1997
by a foreign car specialist shop, and now I'm starting to experience problems
in 1st and 2nd gear. When I'm at a complete stand still and accelerate,
I have to let up on the clutch very slowly or it will stall and almost cut
off as if the clutch is too tight, like I'm dragging on the flywheel(this
was told to me by two individuals), but once I start to accelerate and I
shift to 2nd gear, instead of a smooth continuation of speed, it would grab
and slow down and I would have to depress the accelerator down almost to
the floor before speed would catch up. And now its starting to do the same
thing when I shift to 3rd. I've also heard that 300zx are sometimes geared
too high. Is this true?
I have 148,000 miles on my very cherished Z. Also my reverse
lights are not working. Sometimes the would blink on for just a few seconds
as if there was a short or if the connection was not true. Is there some
type of connection with two wires that attaches to the transmission housing.
The bulbs are in good working order.
Sorry for the long questions.
Thanks In Advance

Hi Ralph, Doc here, it sounds like you are experiencing clutch problems
again from your description. Does the transmission make any sounds that
are abnormal? Listen at idle in neutral for anything that is not a normal
sound.
How is the gear lube? Have you ever changed it? There is a magnet on the
drain plug to collect metal pieces that could migrate in the gear lube and
is an indicator of anything that is starting to come apart, like a bearing
shield.
The third thing that is you describe is the characteristic problem with
the reverse light switch. Many times they just get tired and stick from
wear, so I would order a new one from your local Nissan Dealership Parts
Department. The connector is a special one so it is not available from
an after market source that I am aware of at this time.
Since you are having some questions about the clutch I would like to have
you review the repair order to see if the clutch parts were Nissan ones
or something else. Many times especially in your location it may not be
a convenient to wait and get the factory parts so another brand can be substituted
for getting the job out of the shop. From your description is is possible
that there is something that came apart from the center of the clutch hub
and could be wedged in the pressure plate fingers. This would be a good
probability since your description of having to feather it when engaging,
like something dragging.
I hope that this sheds some light on the subject for you..........So how
is the Weather in St. Louis?
