Yep We're jealous of full boost at 6000rpm with a gtx35

Back again, 372kW @ 1.75bar (1.8bar spiked a little)... motor has not popped and even went to a track day on the 30th of May. Motor did push some coolant, I believe the OEM head gasket isn't too happy

Impressive power for an unopened motor. ...

Not sure if Royce has posted here, but he is running 730whp on his stock bottom end neo.

Or maybe it was 630. Either way, impressive.

The precise symptoms I was talking about. My 33, and a couple of other customers had the same issues after using motul. Not sure why.

What Nulon did you put in your 33? How long was it on the motul with ticking before you swapped over?

Sorry for all the questions!

He's now at 850hp on standard bottom end. Only has cams/springs/studs. Check post #1035 in rb25 turbo upgrade dyno thread.

That dyno curve looks like a V8's, need's some early spiking on the controller

Was that in reference to my dyno ? When it gets retuned i will have the ebc in there that boost is just straight from the waste.

Reason i havent gorne higher boost is no studs or gasket but may look at setting it to spike upto say 20 and run 18 19 should also make 30 40 more uptop this time as got free flowing exhaust to go in

Problems with motul oil was almost instant in my R33, Which is why I thought there may have been an existing issue with the lifters, but then was told about the exact same issue with other 25's. Couldn't tell you how long I had the motul in there with the lifters.... but it wasn't long. New lifters in, and full flush and oil change, including oil cooler etc. Never had another issue.

Tuner didn't elaborate on the other 33's at his shop it'd happened too, just it was why he doesn't stock or use motul any longer.

There was another issue with your setup if the Walbro 460L stopped, they are nearly bullet proof Ashley, and flow substantially more than the 044's.

Don't bother with the highmount, if you externally gate the turbo the stock manifold will flow 450 odd kw with better response. There is plenty more in your current setup by the looks.

I'm not sure how much mine is making but what about the 21u high flow?

I believe is only rated 30 hp less than op6...will ewg improve?

I can list my mods though if needed

Ps. U mean 450 odd hp and not kw right?

Less back pressure, more power so if you relieve as much back pressure as possible your motor aka air pump will flow more air thus producing more power.

Another reason why going a decent manifold and EWG will make more power however with some added lag OR same can be said about welding a gate on top the housing and ditching the IWG.

Wouldn't high mount be a good thing at that power level, if the tune is averaging EGT's and mixtures then having equal length runners should give a better safer tune for a stock bottom end?

      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).
