Well im aiming for about 230-240kws, i know i could do the conversion thing but i dun wanna ;p i like the RB20 if revs like a mofo.

i was thinking along the lines of mods:

-R34 GTR fuel pump (legend sled)

-444cc or 555cc injectors

-Cam Gears

-Cam shafts (been quoted $820 for a set of RB20 cam shafts 254 DURO and 8.5 lift) <- sound good??

-Bigger turbo, been looking at the hypergear turbos, i like the look of the TR43HF.

the cams part sound ok???

IMO I think Martin Donan from Willall Racing is one of the best tuners in the country and I know he has recently stated that a bigger turbo will always give you the biggest noticable hp increase so for a few $$$ more, I would be looking into getting that area sorted out first. Once you've got your turbo, fuel & ECU sorted out, its then a matter of choice as to what you are using the car for but cams & gears would be the obvious next bolt on to consider. My personal favourite for the street is the Tomei 'B' Poncam but rev210 who has had more hands on experience with cams on RB motors specifically may be able to further advise you in relation to choice.

Hope this helps.

im looking at almost the same...

except i have a

gt2530

gtr injectors

pfc

gtr pump..

and was wondering how the cam/cam gears are going to help.

cheers Sled. and who is this tuner? SA?

Yeah he's in Adelaide in the northern suburbs and he was involved with an R32 with Pete Hall that was the quickest in Australia 8.8sec 1/4 mile @ 160mph.

What side of town are you at cos there are 3 tuners down south that are also good.

Joel..

You can get a set of Tighe regrinds with a 254duration 8.5mm lift for $220-$300 + the std gtr sticks which can be picked up for 60-100.

rbman went with the 254's (708c grind), I believe they set him back 220ish. Simon went the 261's (805c grind) that set him back ~$300.

Don't go too big in the cams department with the rb20 as port velocity will suffer and turn it in to a lazy disappointing drive.

Myself.. 805c.

      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).
