Anyone with a US car changed the speedo (or changed the face) to KMs from miles. The inner tick marks don' t provide much resolution.

i would believe it would be quite expensive to do the swap especially ordering from Acura if even possible

You're spending at least a grand. Probably better off buying an NSX-R cluster at that point.
but doesnt the NSX-R only go to 180 KMPH
 
The 180km/h clusters can actually be useful up to around 210 km/h - the needle keeps going until it hits the peg at 0.

For regular driving I find the JDM gauge very pleasant, the numbers are big, and you can quickly read your speed at a glance to an accuracy of 1km/h.

If you're looking to record top speeds on the straight at a track, a GPS with max speed recording feature might be a better option rather than trying to watch the speedo right at your braking point.

Just my AUD $0.02!

Dude, I'm the king of US cars - lemme tell you what you do:
30 = 50 = sidestreets where people know you
40 = 60 = sidestreets no cops, or mainstreets w cops
50 = 80 = mainstreets no cops, or country roads cops
60 = 100 = country roads no cops, highway beside a cop
70 = 120 = Cruising speed (anywhere)
80 = 135 = Highway no cops
90+ = loose your license driving a bright yellow car that the cop is gonna hate you for:rolleyes:

Memorize this chart, and spend $1,000+ on something worth while.:biggrin:

How exactly did you find that out mate??? :wink: :biggrin:

Second question, what happens when you exceed 210 and the needle is prevented from moving anymore? Will it damage the mechanism?
 
Red seems to have it all figured out!

Steve if a straight swap could be made - maybe you could work out a swap with a Canadian who has moved south of the border, or an American who has moved to Australia etc via the WTB forum?

You could achieve a cheap fix by making new label to stick over the top of your speedo gauge numbers, underneath the needle. Ie replace 60mph with 100km/h etc. If you need to go back to MPH one day, simply peel it off again. Depending on the time spent it might not be quite so pretty, but it would cost next to nothing.

AU_NSX. Good question :) It's just my guess but as I believe the NSX speedo is electric driven by a varying voltage, rather than mechanically driven by a rotating cable, so there would be no gears to strip, and that stopping the needle prematurely would have no ill effects.... but that is just my guess. I'm sure a Japanese member would know, mine's probably just one of thousands of Japanese NSXs with the 180km/h speed restriction removed. It's a bit academic for me though mate, at over 210km/h, I think kangaroos, pigs, cows, pigs, sheep, pigs and people are at the top of the list of worries and the speedo gauge is dead last on the list :)

Doesn't the needle fly off from pressure against the hard stop, break the lexan cover and hit the driver (hopefully nowhere "vital" since the needle is about 4" (or 10 cm if you have a metric cluster) long!:biggrin: :wink:

I've seen it happen in cartoons!:wink:

What you don't know for sure??? I thought you were the expert... :tongue:
 
hi, mines JDM so a kph speedo, with just the kph markings.

In the UK it has to be in miles per hour, so when it was imported a 'black-box' (basically i think it's a frequency converter) was added to the back of the speedo to convert the input signal to an mph one, and a 'mph' label put over the 'kph' legend. now it has a 180mph speedo!

so easy fixes are out there as it's a common problem for imported cars to the UK!!

The only way I'd know for sure is if I converted my speedo, went fast and discovered I had a toothpick in my cheek :eek: (thankfully not but cheek, since I'd be sitting on that one!)

I'm happy with my MPH-KPH conversion technique!:biggrin:
 
heheh... boy do I miss these Canadian threads!

I have a JDM cluster and I have buried the needle with no noticable damage. It just stays pegged...

In the summer I'm going to pull the cluster out again to do some LED work so I can pop out the speedo gauge and swap it into the USDM cluster and see what that does since I still have my old one. The only issue will be that the ODO will still be MPH if it did indeed work...
 
Why can't the US just capitulate to the SI system!

I mean how many space probes are we going to have to loose before someone realises that the imperial system is fundamentally flawed! There is a whole generation now who grew up with the SI system and have no idea how many inches in a metre and which gallon or mile are you talking about!

Oh yeah, and I am so sick of the printer telling me to "load letter"...

:tongue:

The americans CAN'T go metric - if they knew their penis size in cms they'd freak!:biggrin:
