Skylines have have this as do all imports due to the speed cut imposed on japanese domestic cars, they are only supposed to do 180 thus they dont need to put any more numbers on the dial!! You cant get cheap 300k speedos they are all pretty dear, id suggest unique autosports if you did seriously want one!!

I got a nizmo 320 or 340km/h speedo on mine. Came with the car and I checked out the price for one. No way I would get one myself personally. Get the Apexi RSM if you want to see yourself go over 180km/h. You get the bonus of removing the limiter.

someone offered me $90 for a set of skyline white speedo face, he said can do 320 face as well... this means your whole speedo cluster (tacho, boost, fuel, etc)

however the question is, if the electronic behind the face is a 180 speedo, what will be involved in changing it to suit 320 km/h face????

you'll need to get either an aftermarket ECU or piggyback unit which can do a speed cut, or something like an RSM. If you wait a month you can guy my HKS Speed Cut Defender which will also do the trick.

I know abt speed limiter, but my question is:

If I change my speedo face to 320 one, while the electronics behind it is standard 180 speedo, how can this be recalibrated?

Otherwise, if the needle shows speed of 320km/h, it is actually only 180km/h in real life because I only change the face plate, not the whole system... (think as if someone just stick a sticker dial 0-320km/h on top of your speedo)

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
