Well, I've just calculated that I'm getting about 250km on a full tank on my R32 GTR. Most of the driving is during traffic and below 100kmh (never been on a highway yet).

Is something wrong? I'm not pushing it hard, driving it leisurely. I have a feeling that its running rich or something needs replacing.

So, if I take it for service how do I ask to get it checked for this problem? i.e. My car is running a bit rich, how do I make it run a little more efficiently because I don't need the extra power or early boost for daily driving. Could someone guild me to how to ask this in Japanese? Thanks!

as a baseline figure, the city cycle for an unmodified r32 GTR should be around the 4.7km/l mark (according to driver magazine)*

* FD of the same era, according to driver, is around 5.6km/l - for those who are always pick on our fuel economy :(

Mate 250km on a full tank!...as Rezz suggested I'd check the CPU.

As 250km is as bad as mine on city driving and I've only got a 50L tank compared to 72L in a BNR32.

As a reference 10-15mode is 7.0km/L and 8.2km/L (after '93 model).

Hey thanks people.

My car's a late 91.

I can smell petrol in the cabin when I drive so something's going on there.

So I have to check the following :

- ECU (would I need to reflash this regardless of whether its stock or not?)

- O2 sensor

Thanks again.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      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.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      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

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
