I get my 33 back in a couple of weeks (hopefully, they've had it for 6 weeks already!) its getting a complete Forged Rebuild. I was wondering what people feel as the best fuel to use, what you guys feel you get the most power and most km's from?

Thanks in advance for the replies! :(

optimax is also pretty good - but in my experience (my car is stock) ultimate does the best. what have u been using? try it with all the top of the range fuels - see which is better.

I have been using BP Ultimate, seems to run pretty well with it, haven't tried anything else though.

out of the normal 98 premium they are all the same. there is little difference between them. ive heard of people saying their engine is tuned on bp premium 98 and they must only use that. its a load of poo and its all the same.

baseline 98 premium, as long as the octane count is the same or close ish its fine and acceptable. ive tried many various 98 premiums all getting the same results. most people claim better economy and so forth on like vortex 98 vs bp premium 98 and so on, its a load of poo.

but overall optimax extreme is the readily (easily) available 100 or 101 octane fuel that would be ideal

yeah this was covered last week, basically i reckon its all the same shit and its all around the same averaged rating. that is, assuming we are comparing true 98 ron fuels. sure there are bad batches of fuel and so forth but overall its probably the same shit. also BP dont have any crap in victoria so they share from other refineries, ie: they borrow tankers & crap

    • 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       
    • 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).
