yeah the wheel size/diff ratio wont affect the measured speed displayed by the speedo, because it is tailshaft rpm, and that ratio will always remain the same regardless of wheels/diff<edit> (unless it has been calibrated). so what im asking, does anyone else have a 5th gear that looks like that. or do i have some freak short ratio box.

alternatively, the car is running a microtech ecu. could the tacho be reading incorrectly? the avcr reads the rpm different to the tachometer.

when the car was tuned last i told them to put a limiter on. and unless they set it somewhere on the wrong side of 8000rpm, it hasnt got one. which makes me think, maybe they did set it. and the tacho is reading high. going back for another tune in a few weeks i guess ill get them to check it out.

nah i said that the ratio wouldnt change unless it had been recalibrated, and as far as i know, mine hasnt. the avcr reads 200rpm at idle. i dont know whats doing there. its way off. but yeah its the original rb20 cefiro box with a rb25 infront of it.

    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
