haha.. thats right.

that is not the car to be getting ideas off. As a budget drifter maybe.

that car is packing a chinese greddy copy plenum, chinese turbo, chinese manifold, chinese gate and the engine bay is disgusting.

he makes it all work, doesnt mean its a good idea though.

for the average punter its not a bright idea to push 370's anywere near that

That may be true but it is an indication of what can be made from them. And that car was not a 5 minute car either.

BTW the calculation I use for injector sizing is (CC of injector / 5) X Number of cylinders = engine hp at max duty.

If you start to increase fuel pressure, the calculation changes slightly.

Hmmm ye true.

What about acceleration enrichment and that kinda thing?

You've got no room if you calc it @ max to begin with. Even a figure of 10% which would perhaps be enough, brings it back to 400hp

I know where you're coming from and it is a valid point but accell enrich only comes into play for a fraction of a second when the throttle is depressed quickly, then it goes back to normal. Seeing as though it's when the engine is at just over maximum torque with a decent rpm and considering that rpm on our cars is usually around at least 5krpm and up, then that accell depression would have to take place at that time and power delivery would have to be instantaneous. In the small fraction of time that the injector needs to deliver that tiny bit more fuel, the engine would still be building boost for a small amount of time, therefore, still getting up into it's peak torque area.

I suppose it could be an issue if you put all things into consideration and they all happened at once. Would be rare for it to be an issue but I don't doubt that it could happen. It's always better to stay on the safe side of these things, no doubt at all. But still, with an easy maximum at 280rwkw, I think 250 or even 260rwkw would be nothing too much to ask out of the standard injectors. Of course it all comes down to having everything else right too. If you have a shit fuel pump it's going to let the whole package down. When you run close to the edge, it's always risky business but if you have all systems in place, it can be just as safe as anything else. I reckon, if in doubt, upgrade. If it's not in your budget, then tune it down til it is.

I don't want anyone to get the wrong idea with what I'm saying, it's always better to be safe then sorry, it's good to know the limitations of ALL your hardware but only go down that road if you are prepared for the consequences. And yeah, if in doubt, ask or upgrade as above.

      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).
