Your USDM speedo is probably busted, thus no workie.

1. Get USDM gauge cluster.
2. Take tach out of JDM cluster.
3. Put JDM tach in USDM cluster.

Now you have the speedo you want, an odometer that reads in miles, and the right tach for the SR.

You may have to give up on the digital cluster and go analog. The digital units are notoriously unreliable. This is widely known, and these issues could have been found through searching.

definately the easiest way to go about having a speedo and tach... but then that only reads to 115

No, im using the digital one... I think it goes past 115

Oh, yea.. the hud goes to 299 :)

Yea .. to bad my car don't! I could stop saving up for the damn Bugatti Veyron!

Hey if anyone wants to trade a JDM HUD for a norm. JDM, I'm down if you pay shipping!

If I change to the Non HUD JDM cluster, do I need the harness or will the 240 non HUD harness work?

you wil need the HUD Sub Harness.

to get rid of the HUD?

One of you guys should wire up a switch to bypass the resistor. Make sure you pick a resistor that gives you the target resistance without adjusting the potentiometer. That way you have a switch similar to the switch on the Corvette C5 FRC... you push it, and it switches between kph and mph.

I'm new the the SR20 forum. On my S13 I have the electronic dash that can convert from km per/hr or mph and shows the image on the windshield. There is a name for that but I forgot what it is oh yeah HUD. With my current set up the fastest I have gone is 148mph I don't even know what my car is capable of yet since I just purchased it about two months ago. Does anyone else have the same dashboard?

I got 180kmh in mine... try figurin that out while ur doin it?!?

Many people have digital dash.

Most don't work. They're notorious for failures.

If you went 148mph, I'm assuming heavy mods? Especially since the stock ECU is limited to around 120?

What does that have to do with the price of rice in China?

Yeah I have the Apexi Power FC with lots of bolt ons and the S15 turbo I think T-28. I brought the car with these mods but I am afraid of over-reving the motor because I don't think it has a rev limiter. The engine will go a little past 8000 RPM's which I don't think it is suppose to go to without a built head right. I shift at 6200-6500 but I need to get it tuning so I don't blow the motor.

Just food for thought...while you're fucking around with your wiring, you could make a cutoff switch for the speed sensor. No speed sensor, no speed governor... so just stick a switch inline with the speed sensor wire going to your ECU, and flip it when you want to go fast...

Once you're done killing yourself, flip it back on, your speedo will start working again, and your car will once again be limited...

No speed sensor, no governor...

... no speedometer, no odometer. Arguably neither method is easier, but at least with the speedo-resistor method you can tell (roughly) how fast you're going.
