car in question is an r32 gtr. this used to happen occasionally but at the moment (i've been driving it quite frequently) its constant. without the ac on i can feel hot air coming thru the vents and at my feet as well. temp gauge is a tiny bit above half way. is that normal or is that running pretty hot? not sure what it could be. car had a full fluid and filter service just a couple weeks ago. any clues? cheers guys. oh also, last night the speedo needle was shaking heaps.

yeah i'm pretty sure i already tried that, but i'll try again just to make sure. but is the temp gauge normally that high? i know my falcon ran a lot cooler and i know its not a good comparison, but still.

press the recirculate button when a/c is off. fixed.

are you going off the stock temp gauge or one with deg? if so, what temp does it get up to?

anyone know what the safe temp range is ? mine sits anywhere from 80-95 depending on driving

Speedo needle shaking? mine jumps around when sitting at 100-110kmh

yeah its just annoying cuz it didn't used to do that. thought in some crazy way it had something to do with the heat. i'm going of the stock gauge so i'm guessing it may not be so accurate anymore. and yeah, heat problem fixed. can't believe how dumb that was.

If you get hot air when you have the vent open to outside its probably the heater core tap getting stuck open. Mine used to blow hot air at me when i was on the freeway and id stand on it for a few seconds. Probably the increase in water flow thru the core pushing the tap open...

a bouncing or shaking speedo needle is a really strong sign that your speedo cable needs replacing. that cable also controls the steering to some extent. worth replacing it before it dies

Not necessarily true. Before my speedo cable let go, it was working perfectly, no shaking or bouncing, it died suddenly.

And I got it fixed, got an aftermarket one installed profesionaly and now the sucker is bouncing like crazy.

Oh well.

have you had it looked at? maybe ask the blokes that fitted it for you why the needle is bouncing.

i have known of 4 32gtrs a 32gtst and a 180 that all had bouncing needles (my gtr included) and they all turned out to be worn speedo cables. i replaced my cable myself with a genuine new cable from nissan. works perfectly with both speedos that ive had in my car.

im not saying that the speedo cable IS the fault, just a very good chance it is :)

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By GTSBoy · Posted

      I hadn't thought about the variable power steering assist. Presumably, it will always be the same level of assist as you get in an S14. The R32/3/4 are either helliishly heavy (at low speeds) if the solenoid is not powered at all, or hellishly too light (at high speed) if it is powered all the time. I presume that it is PWM controlled on those cars. I hadn't thought about the S cars not having variable assist. ugh. What crappy plebby cars they must be!

      Hmm yeah that is a good point. It looks like it'll just bolt in with no real issue besides maybe the bushings being different. My other concern was that 2 pin plug that I assume is used in some way to control the rack solenoid depending on the speed signal from the ecu. The DMAX rack doesn't even have that plug though so, don't think it'll matter. Might just order the rack and see how it goes. Will update this when I figure something out

      I'd say it's a fair bet that the feed and return fluid lines will be in different enough spots that you would need to come up with a way to cut the originals short and adapt with new hard line adaption or braided teflon hoses or somesuch. But really, you have the car, you have the photos of the DMAX rack - you should be able to go out there and see for yourself whether they're in the same or different spots.

      I've been doing some looking around and honestly was just considering throwing a new rack at it. I saw that the dmax silvia rack bolts up into the 33 with the silvia bushings but not sure if the high pressure lines will sit in the correct spot. I believe other version of the 33 rack are the same/similar to the racks that can be opened up without as much fuss so I assume the dmax rack would fit but any ideas?

      I've never played with one, but I would expect that you are correct. That slot looks like it is intended to be used to unscrew the end, and the flats on the body would be better than grabbing it around the round bit with a pipe wrench. So, yeah, probably unscrews. You'll probably have to make a tool to drive in that slot.
