guys what do you think is better for my gtr, aiming for about 350kw and as i said i got these injectors which i thought were 600cc with the purple tops but they turned out to be the nismo 555cc, will these injectors be good enough for my sard 280 pump along with an adjustable nismo fuel reg, will they be good enough for that power range, because i dont want to really go through the hassle to return them back,

guys what do yous think of these nismo 555cc injectors, is there a big difference between these and the 600cc nismos, these retail to alomst $1200 these days so they arent cheap but thats not the Q, will these be good enough for my application

please guys can yous help me, i would really appreciate it

cheers tony

555's would be able to do 350kw. Wont be a lot of room but enough. Worse case up the rail pressure 2-3psi and it'll sort that out

hrmm, what do you mean by up the rail pressure 2-3psi?

are they a much difference then 600cc injectors?

i just spoke to a mate of mine barry form edge motor works who is local to me and helps me out, he said nismo 555cc would be perfect for around 330awkw or something, he sais the bigger injector you go the more juice i go thrugh, he said stick with nismo 555cc injectors and with a decent tune they will be perfect for that power figure im after, really only mods i want after this are the -5 turbos and the tomei 260 cams with around 18psi and ill stop until the car needs a rebuild

yous think it will be all good guys?

The 555cc Nismo's are the best injector for your application - they are by far the injector of choice, the sards are crap. Besides you only need about 8psi more base pressure to get you to th equivalent flow of a 600cc Inj.

they are a pretty good injector but man if i want to produce around the 350kw i dont really want to max these inj to their limits if you knwo what i mean, my aim is for around the 350kw mark, i better just send them back

thanks guys

guys called up ben at racepace yesterday in the morning and he said that the nismo 555cc injectors are good for 350-360kw, he goe it just depends on the tune so he said nismo 555cc are an excellent injector and perfect for your application so i guess i should listen to him and ill stick with the nismo 555s,

will get yous the dyno results after the car gets all done and tunes at racepace, before with the stock gtr pump, stock injectors it got 245awkw at prottek automotive at 1bar, now ive upgraded the pump to a sard 280, injectors are nismo 555cc and also have purchased a nismo fpr so will like to see the results, only thing that stuffs it all up is that it still has the stockturbos, but soon to be upgraded to gt28/60r -5 or -7, we will see what ben thinks

thanks for the help guys

cheers tony

      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).
