well the fuses are under a panel on the left kick panel in the foot
well but you probably blew the fuse on the back of the radio
itself..have to pull radio to replace it.. good luck…

    Hi All,

    I recently bought a 91 300ZXTT, and it’s wildly fun, but yesterday the
    stereo refused to come on… I figured it was probably a fuse, and so
    began my quest to find the interior fuses for the Z. Are there any? If
    so, what’s the location? There seem to be two fuse blocks under the
    hood, one up by the battery and the main one near the front left of
    the engine. I had expected there to be a whole separate fuse block for
    each interior component, or at least that’s what I’m used to on other
    cars. Anyone who could put me right on this would have my thanks.

    Trying to find the fuses led me to try to get a shop manual from a
    couple of local parts stores. Seems there is no Haynes or Chilton’s
    manual for the 90+ Z. Is this true? Are there any shop manuals
    available, and if so, where might I acquire one?

    OK, last question. I have been considering getting my mechanic to
    start making some mods to the engine. His view is that in order to
    really get a noticeable difference in performance, you need to do the
    whole nine at once – intakes, exhaust, boost valves and computer.
    Information I have found at Jim Wolf Racing and Stillen claim that
    exhaust and intakes alone (i.e. not having to adjust the fuel curve)
    will net you over 30HP. Who do I believe? Anyone out there done this
    work/had it done, and what was the verdict.

    Thanks in advance for replies…

     Deviod,

    First, the problem with your radio is likely the fuse physically
    on the radio, you’ll have to take it out. Not too tough, I think it’s
    just 4 screws on the front of that middle panel (below some plastic
    pop-on shields) and you can access it.

    Second, I’m not sure about service manual, I’m still looking for one
    for my 92TT. There are ‘actual’ service manuals available for $50. Since
    I intend to keep my Z for a long time, I’m probably going to make the
    investment. If all else fails, these are available from Nissan. There
    is an order form in the back of the owner’s manual.

    Third, about the upgrades. You may consider switching mechanics :)
    Ask him if he’s ever driven a 300ZXTT! Yes, just doing the exhaust
    nets 20 HP, then just adding an intake adds 20 more HP (total 340),
    then the computer adds 56 more to 396. These numbers are correct,
    and measured on a dyno (note, not at the flywheel), actually at
    back wheels. Do what you can afford and enjoy *that* first. I’m
    saving up for an exhaust right now, and it’s the most expensive
    mod I’m going to do, the intake and ECU are cheap compared to it.

    Happy Z-ing!

      Michael I hate to break your bubble but 396 hp is a flywheel rating,  not
    at the wheels. I work at a dyno shop and a 300zx tt will not make 396 rear
    wheel hp with just (exhaust, computer, intake)…, if it did the car would
    be making over 467 hp at the flywheel adding a very conservative 18%
    driveline loss. That’s 167 extra ponies. Don’t get me wrong turbo cars
    benefit from intake, exhaust, computer upgrades better than naturally
    aspirated cars but this is a little extreme.

    Devoid,

    The upgrades are 1) ecu (Jim Wolf makes the chips, Stillen resells them, so
    you can buy from either place and get the same thing – just don’t mess with
    Superchips) – do that first and you can do that yourself.  You’ll think
    it’s a whole new car.  Then get the intake (can do that yourself) and
    exhaust (probably can’t do that yourself) and you’ll be at ~400hp.  This is
    for a 5spd.  Call Jim Wolf – they’re good to talk to and will answer your
    questions.

    Sounds like your mechanic is completely ignorant about the Z – better to do
    the chip and intake yourself (not hard – really).  What does he mean by
    boost valves?  If he’s referring to blow off valves, that’s a total waste
    of money on the Z – it already has recirc. valves that do a better job than
    aftermarket blow off valves.

    A manual is not available from Haynes (at least I never found one), so buy
    one from Nissan (kind of expensive, but it will save you plenty of $$ –
    trust me).  And subscribe to the z mailing list (www.zhome.com) and read
    the forum at http://www.twinturbo.com.  And DON’T TAKE THE CAR TO THE NISSAN
    DEALER!!!  

    Oh yeah, about the stereo – 4 screws to get it out, but you have to pry off
    2 screw covers towards the top, and then a screw cover plate just above the
    radio to get the console out

    later,

    My apologies, I was told that they were. Thanks for correction… Still,
    point is true, you do gain some benefit, so it would be 300 to 396 at
    the flywheel. Quite a gain still – my mistake.
