I took out my white speedometer kit, in my 94 R33 NA, and after putting it all back together the speedometer doesn't show up the right speed. IT shows up roughly half the speed i'm doing. So when i'm doing 80 it shows roughly 40. The car is running fine, and i don't have a problem with the taco. Any ideas?

My mate took the cluster out of his Toyota and removed the plastic front, put it back in then followed me at 60 according to my speedo. He held the speed, pushed the needle back on at 60 and replaced the plastic front. Been correct ever since.

ahhh quality mechanical work, there's just nothing finer for your 87 camry

Haha see the reason i asked was because i just had my car converted from auto to manual and the automatic cluster reads only half the speed. pretty much exact same problem but different.

I have heard that there is a way to re-calibrate it from the back of the cluster but I'm unsure on how this is done, should probably search it up im sure its been covered at some point. One thing you can try is unplugging the cluster, starting the car, then plugging it back in while its running. This seemed to do the trick with my old tx3 turbo, but i cant guarantee anything.

there is a tutorial on adjusting the cluster on this forum somewhere. it is done by soldering up jumpers on the back of the speedo.

also if you converted the car from auto to manual and didn't change the diff then it will read out as well because the auto diff ratio is different and the speedo reads from the gearbox.

Yeah i had the cluster changed to manual and yes its still running auto diff, i prefer the higher gearing to manual one. Its only out by 3km/h at 60, and 5km/h at 100 (reads lower). Ive checked it out with a couple different gps units. With 18's on it reads perfect again so no problems there for me :D

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.

      Yes they do. For some maybe. But for those used the most by abusers, ie Skylines, the numbers are known. The stock eyebrow height for R32/3 Skylines is about 365/375mm or thereabouts. The minimum such heights are recorded in adjacent columns in the database.

      Hmmm, interesting. Makes me wonder whether there is bias as well. It's the cheapest fuel, so it is used for all kinds of ill-maintained shitboxes which are bound to have issues regardless. Nicer cars tend to require higher octane rated fuel and can't use it anyway. FWIW, the official NSW E10 facts page is decent.
