BLOZ UP Posted June 20, 2012 Share Posted June 20, 2012 I got some Speedhut gauges a while back and decided to install them now. I got: 4" Revolution GPS speedometer, with fuel gauge, turn signal indicators, and high-beam indicator 4" Revolution 8,000 RPM tachometer I installed them in the housings of the 280Z gauges. I put the new speedometer in the 280Z's tachometer housing and dash location. I used the 280Z speedometer's location and housing for the new tachometer. I heard about other people using a small 4" section of PVC pipe. I just used the old tachometer housing's screw retainers for the speedometer. For the new tachometer, I had to cut out the back of the old speedometer, and then I used some laptop screws so that they would extend further in the housing for the threaded ring to catch. So far, so good, but I haven't wired it up and tested it yet. The full writeup is here: http://www.blozup.com/node/37 Quote Link to comment Share on other sites More sharing options...
Dershum Posted June 20, 2012 Share Posted June 20, 2012 Very nice...this is the exact same route I'm planning to go with. Did you get temp/oil press gauges for the other pods? Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 21, 2012 Author Share Posted June 21, 2012 I haven't yet got any replacements for the 3 gauges. I have some Greddy 2-1/16" gauges just ziptied where the radio goes at the moment. I want some 2-5/8" ones for the 3 gauges in the dash. Will probably be boost, oil pressure, fuel pressure, which is the same as the Greddy ones I have now. I'm wiring it up right now--I believe my high beams to be shorted. I can't get the LED to light properly, and I'm using a relay. Man they didn't think this through when they designed it. Either that or relays were really expensive back in the 70s... Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 21, 2012 Author Share Posted June 21, 2012 (edited) I finished the wiring. Besides the high-beam indicator, it went smoothly. The high beam indicator is on a switched ground, and receives +12v all the time (or at least, IGN). So I hooked up a relay to activate upon being grounded, providing +12V to the new Speedhut indicator. However, it doesn't work but I believe a fault in my headlight wiring--my high-beams don't work. Other than that you can group all the gauge power, ground, and light connections (for both gauges and gauge lighting inverters), to the same 3 wires. The gauges take a fraction of the power the original ones consume. Also pictured is part of my new 240Z wheel. It's nice to not have a wheel wrapped with electrical tape anymore.

BLOZ UP Posted June 21, 2012 Author Share Posted June 21, 2012 I also routed the parking brake light to the otherwise unused floor temp light. Quote Link to comment Share on other sites More sharing options...
ktm Posted June 22, 2012 Share Posted June 22, 2012 Why did you still use the clear plexiglas cover? I ditched mine when I did my install. I use the stock front black plastic trim piece as well and only friction fit my gauges into place. I also used a relay for my high-beam indicator, but unlike you mine actually works. I gotta say, I love the combo speedo/fuel gauge setup. I wish they had that when I ordered mine. Quote Link to comment Share on other sites More sharing options...
Sumo Posted June 22, 2012 Share Posted June 22, 2012 I kinda like that fuel gauge too. Quote Link to comment Share on other sites More sharing options...

I gotta say, I love the combo speedo/fuel gauge setup. I wish they had that when I ordered mine. Good question... I removed it to test fit but didn't like the lip that was left over. I tried to make it look stockish. But really, it's kind of a pain to push the buttons. Have to have a screwdriver in the car. But I have a bunch of spare ones since they always have that free screwdriver set deal at HF. They hand those things out like they're french fries in a combo meal. The stock fuel gauge apparently has filtering in it. My new one bounces a little during braking/accelerating from the slosh in the tank. Not a big deal.

luigi Posted June 22, 2012 Share Posted June 22, 2012 (edited) What fuel sender did you use? Are the gauges easy to calibrate? good looking stuff thanks Luigi Edited June 22, 2012 by luigi Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted June 22, 2012 Author Share Posted June 22, 2012 I used the stock 280Z sender. I just switched the wires from the stock gauge to this one. They are pretty easy and logical to calibrate. Quote Link to comment Share on other sites More sharing options...
Oddmanout84 Posted June 25, 2012 Share Posted June 25, 2012 Damn. And I thought I had waited until the right time when I bought my Speedhut gauge set with the indicator lights in the speedo. Now they offer a fuel indication too? Sheeeeeiiit... Nice install. Quote Link to comment Share on other sites More sharing options...
Stevemd24 Posted June 30, 2012 Share Posted June 30, 2012 I am looking into gettting gauges that look like the should be in the dash. These do the trick, but... Just a random Question, Why would you get a Gps speedo? Versus A normal one? anyway one last question Do you have a link on where you purchased your gauges?

BLOZ UP Posted July 1, 2012 Author Share Posted July 1, 2012 Because now I don't have to worry about speedo cable/wires from the transmission, diff gear ratios, tire sizes, etc. It just works. It's getting a signal in less than a minute, which is faster than I can pull out of my driveway. They are Speedhut gauges. A google search would lead you straight to their website. I purchased the Revolution gauges. Quote Link to comment Share on other sites More sharing options...
ktm Posted July 1, 2012 Share Posted July 1, 2012 If you have a car with a "modern" transmission that uses a digital speed sensor, I would opt for the normal speedo. Calibration of the speedo is stupid simple even for ratio changes due to gearing, differentials, tires, etc. However, if you have a mechanical sending unit in an older transmission, the GPS speedo is the way to go.

Stevemd24 Posted July 1, 2012 Share Posted July 1, 2012 I like the Gps one you have shown, with the with fuel gauge, turn signal indicators, and high-beam indicator, But i want a non Gps kind, I wrote them to ask if they have one we will see....

dpuma8 Posted November 26, 2012 Share Posted November 26, 2012 I bought the non GPS speedo from speedhut but I have the old speedo cable. How do I make this all work? Quote Link to comment Share on other sites More sharing options...
3ryce Posted July 22, 2013 Share Posted July 22, 2013 (edited) Did you have to use a msd tach adapter with this or can you use a tach from there with out the adapter. I have a 6/73 240z and have a msd type 2 blaster coil. currently tach does not work. it can, but no adapter. and Im gonna upgrade the speedo eventually but i need to start with the tach first. Also was this done to a 240z or a 280z? i keep seeing 240 then 280. kinda confusing a little haha. Edited July 22, 2013 by 3ryce Quote Link to comment Share on other sites More sharing options...
BLOZ UP Posted July 22, 2013 Author Share Posted July 22, 2013 I have a MSD coil of some type, but I'm not using a tach adapter. This is on my 280Z. I am running Megasquirt, but the tach is triggered from the coil's negative. Quote Link to comment Share on other sites More sharing options...
3ryce Posted July 24, 2013 Share Posted July 24, 2013 Ah. so ide probable have to use an adapter and the 6A even with a new guage. Could I Use a 280z or zx distributor and then not need the adapter? could i use the stock 73 tach with the newer dizzy or would that still not work? I have a msd blaster 2 coil, I want a new Tach, but I dont think that just getting a new tach will work. So I guess ide need a different dizzy, and not need the adapter. Correct?

BLOZ UP Posted July 24, 2013 Author Share Posted July 24, 2013 I'm not sure, someone with more experience would have to chime in. How is your tach triggered currently in your car? Quote Link to comment Share on other sites More sharing options...
