But you havent tuned the AVCR with the Tial wastegate?

I am pretty sure it will have to be retuned to suit the differences between the wastegates.

yea it has to be touched up but it still should hold boost when it's switched off and it's not, i dunno what the f*&^%kn problem is but it's frustrating the shit out me

Cheers

Ok guys

all fixed after spending damn near 2 grand i found the problem.

First i got the car retuned, changed the cat, changed oil, sparkplugs, oilfilter, changed coilpacks, chanhged wastegat, all to find out it was the damn airfilter!!!!!!

2 grand for a Farkin $$140 airfilter all fixed and now pulls like a bitch! got the car retuned and she made 251.9 rwkw off 18psi and we tuned it back to 241.3rwkw off 16psi cause it started runin a little lean the good old RB still has it nin her!!!

Hitman said that once we get the fuel problem fixed should be able to make about 255 -260 safley and about 290rwkw off race fuel on 25psi.

all in all i'm damn happy with the car now and all that's said and done Hitman is a genious when it comes to EMS's

Well thanks for all the reply's guys.

Cheers

by airfilter do u mean that the intake pipe between the maf sensor and the turbo inlet was sucking closed?

Na i got a metal pipe comin off my turbo to the airfilter and cause i got a microguess it just runs off a map sensor. I have no idea why it caused such a problem.

I was takin out the wastgate again to see if it was that. the gasket fell underneath the air filter and it wasn't on the ground, so i took the air filter off and procedded with the wastegate. the wastegate was fine and i forgot to put the airfilter back on, took the car for a drive and it was fine talk about lucky!!!!

Im interested to hear about what sort of revs the turbo begins to kick in. I bought a Master Power T3/T04e 500hp rated and would like to gain an idea about how the turbo will behave on my RB20. Im aiming for 240rwkw. Does youurs do much below 4000rpm?

to be honest mate it kicks in to full boost at a little after 4500rpm can't wait till the gt30r goes in it, should make full boost at about 4000rpm believe me that's a huge difference.

The GT30r has a .63 comp that's why and a .6 turbine.

      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).
