Hey Guys,

My cars speedo sometimes gets a bit enthusiastic when I start the car after its had a chance to cool down etc.

It seems to be displaying 10x the speed until the car is warmed up and i've turned it on and off a few times, tried disconnecting the battery etc.

I'll be chugging down the road at 22km an hour and it will be showing 220km/hr!!

It only does this occassionally first thing in the morning and once the car has warmed up it starts working again.. what could it be? Why x10???

Thanks :)

Hey Pentae...long time no speak!!

Mate...not sure if these things are cable driven (?)

Get that established first, that way you may just have to 'shake' or play (gently) with the wires behind the speedo!! (intermittent connection????)

anyways, I'm interested in this thread!!

If they are the same as the rb25 box then the speedo drive is electrical, no cable drive :)

mark: Hey mate, thanks i'll give that a go!

blur: the speedo head? is this easy for me to get at? how would I test it?

the reason i'm asking for first hand experience is I dont want some clueless auto electrician to replace everything including the gauge clusters before finding out whats actually wrong with it.. :P

like all japanese cars, the odo has been tampered with, would that have anything to do with it

its tricky to get to the back of the instrument cluster, but not impossible. ull have alot of fun if you like pulling a apart the dashboard. the little motor thing (or its regulator thing) is probably farked. in the short in have no idea how to fix it, have a look at the wiring for anything obvious...electrics are tricky so dont screw around too much. id use this as an excuse to get some aftermarket cluster..and use the old gtr ones as a desk ornament. :( i have one, and i have no idea what car it is from :P

racsov500: Thats cool, i'll see what I can find. I appreciate any help anyone can give me.

I've found that the problem goes away after I let the whole car warm up by putting around under 30km/hr for a few minutes, then turn the car off for a few minutes.

When I restart it it works, but will not start working again unless I turn the car off for more than a minute.

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      Yeah pretty impressive hey, good to see quality products not over-shooting their prices. That's what drew me to buy the hypergear turbo, just a shame I've never got the chance to see it in action

      Thank you GTSBoy and MBS206 I have done the compression test with the motor out of the vehicle, reason for the test was to see if I needed to remove the head and do rings etc while its out. I'm in the process of respraying the vehicle and tidying up a few things. Story behind it all is I've just purchased the skyline and it was running when I got it, never drove it on the street though as I wanted to pull it down and do it all up again before registering it. the gentleman I purchased it from told me the motor has a forged bottom end and has a decent tune through it but I was going to pull the sump off anyway to see if it is a forged bottom end. that's why I thought id do a compression test beforehand.

      Man, I'm kind of amazed that the price of the turbo has not changed in 7 years. Everything else is inflating beyond reason, but not this? Good on Tao / hypergear I guess? Anyways, good luck with the sale!

      Hypergear ATR45 SAT Turbo With addons (brand new - never used)

      I'm selling my brand new, in the box, never used Hypergear ATR45 - and I had some additions I paid for a few yrs back when I purchased it. Never ended up having the rest of the money to add all the mods at once, so I just ended up slowly selling each part. I originally had it internally gated, with the dump pipe, however I found it was incompatible with what I was going to use it for, so I contacted (I think Ken) from Hypergear, and he and I messaged back and forth & he got me to ship the turbo back, where they modified it & made it externally gated, and gave me the 5 bolt dump pipe attachment for custom welding. (Photos below) This turbo like I said has never touched the inside of an engine bay, it's completely brand new, never used, been sitting in the same box it arrived in, covered in plastic & all. Below are the photos of it: And while the guys at Hypergear were making it in-shop, they sent me some photos of the process: I'm looking at selling this just because I'm in need of the money right now, and don't have plans on modifying the 34 anytime soon - and from reviews & peformance sheets, this turbo had amazing results back when I was researching. The turbo was purchased in 2018 for $1.9k, with the mods I got added on. Looking at the website now, for the same turbo they sell (ATR45SAT), with the current addons it adds up to $1830 for the turbo Current addons included: - Bolted dump adaptor - Ball bearing CHRA - Braided oil feeding line So I'm looking to possibly sell it for around $1800, with shipping included in that 1.8k, It cost me around $120 to ship - so yeah thought I'd throw it out there and see if anyone was interested in purchasing. Cheers!
