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

      r34's love to squeal

      Use an LS1 or similar, via kit like Frenchy's. But.... It's probably not the alternator. It sounds like belt squeal, which would be because the pulleys are glazed. Rub every groove on the pulleys with 120 grit paper. Report back. Oh, and new belts afterwards too. The old new ones will be shitted up already.

      r34's love to squeal

      By Nizzy_R34 · Posted

      Hello all I have 2 r34 sedans , one turbo one na, only recently aquired the na 34.  Man what is with these things.... My turbo 34 started sounding like a super charger, it was screaming at anything above 4000rpm , I took the alternator apart and replaced the front bearing which is the only one I think you can access and it did not fix the issue so presumably the bearing in the rear of the alternator is gone. ( diagnosed it was the alternator by taking off the aux belts one by one to figure out which pulley or bearing it was )  My friend gave me one he had lying around, Installed it , it did not squeal for maybe 500kms and now its started to squeal again briefly on startup  Recently got an na r34 and I replaced the timing belt, water pump + all the auxillirary belts. Runs amazing but it suddenly developed the same squeaking problem but significantly worse, Ive had my neighbour come down screaming at me because it was waking her up everytime I moved the car. It takes a good 2 minutes before it quietens down.  Im yet to diagnose where its coming from but im fairly sure its coming from the alternator aswell. My question isnt about how to fix it but rather where can you get a new alternator for an rb25 neo??? Ive searched everywhere but I havent been able to find a direct fit oem type replacement thats not genuine. All the automotive stores sell an oex one - BXA035 - which I picked up for cheap through a friend with staff discount , got it home only to find the connector is completelty different.... As far as im aware bxa035 is for rb20/30's and after a bit of figuring out the bxa035 has an ev14 type connector, which is tiny compared to the rb25 connector. I actually had an ev14 connector lying around which I was considering just replacing the bigger plug with to get the alternator working but the bxa035 is rated for 70amp vs the rb25 alternators are 90amp ( or so ive been told ? ) That paired along with the fact im about to install an amp + sub in the back and I have the stock sized small battery Im not sure itll do the job unless anyone has another opinion?  I know and have seen all the websites selling the ls1 alternator conversion kit but I am not going down that route, nor do I have the money to. Hopefully I can figure out how to get 2 brand new alternators for both cars. I would buy second hand which there seems to be many of but considering how common this seems to be im sure If I installed a second hand one it would start squealing in no time  Or even better if anyone knows how to fix the issue directly with the alternator itself... Any input appreciated Thank you     Link for bxa035 connector picture

      R33 suspension bushes replacement, what wears the most?

      As above, replace as many as you can afford. If anything, due to old age.

      Oil Control In Rb's For Circuit Drag Or Drift

      By Dose Pipe Sutututu · Posted

      Can confirm previous shop that built my motor had no fking clue about oil control and caused my motor to shit itself after two track days. Current shop, Birrong Automotive, has managed to build me a motor, not to mention, has also let me tune it myself and it has yet to blow up after 7 track days. Great oiling success, yashimash.
