Will try pick it up tonight and comment on how it's behaves in the road.

Staying at 35psi. Now I'm tempted to have a crack at running a 9 haha.

580kw is at 7000RPM. I'm getting 35psi by 5500RPM.

Going to try and get an overlay on the 8374 dyno and 9180 dyno runs and share it.

Awesome, look forward to hearing.  Good luck with pushing it off the map like that, it definitely doesn't guarantee failure and you at least know that rpm haven't spiralled off massively at the point it's dyno'd to (don't rev it higher though!!)... so while it's more dangerous it hasn't gone way out of control at that point.  

If it fails earlier than it should however, you also know you've taken the the risk and accepted it :)   VERY keen to see how it drives and goes.  They are a beast of a turbo!

Note to all. Finally moved my cam gears on the dyno. Spent 4 hours there yesterday (on a dynocomm inertial - which will soon be eddy brake). I now see what a V-cam would do for you. Moving my Pon

Yeah you know as well as anyone that some dyno's are happier than others. As you said you want to run 140mph, with that power it should go well over 140mph.

Wack some ET streets on it, soft suspension and run that 9 with a H pattern!

Good luck :)

I doubt it will happen.  There were noises of a 9280 but it seems like the hotside is also a hold up on these things, so they'll probably need a clean sheet or just twins (which I think Nizpro customers have done!?)

Picked it up and drive it home in muggy 37 degree weather.

Initial impression.

It's def lazier than the 8374 down low. You can notice the small lack of pick up and low down but transient response and pick up from say 3.5k and up is very similar to the 8374.

Couldn't really give it the beans on such a hot day. I put my foot down once in 2nd and it did take a while to come on song and was only hitting 31psi due to weather. Haven't really felt new top end grunt.

Will take it out on a cooler night to really test it but at this stage, on a mild 2.6, the 8374 is a better option for a street car.

TBC.

OK I take that back.

The 9180 is awesome!

Awesome :) We already know this but care to elaborate?  How does it drive and go? Response decent once on steam considering the 2.6?

It's smoother than the 8374. The 8374 felt snappier when it came on. This isn't.

Low down there is noticeable lag compared to 8374 but once IMO it's perfectly acceptable to drive around town once ur up in the red range. My short ratio getrag also helps with drive ability.

Top end is mental. Even as the driver I felt a little scared as too how quickly it picked up speed. 5500 to 8500 is where it all happens on 2.6 so a stroker and 9k rev limit with this turbo would make for an incredible street car.

Are you running 4.1 fd with the getrag?

yes standard 33 GTR diff with 34 Box

Great. I hv the same! What clutch are you using at the moment?

My main sport is hill drives. I am currently running a pair of gtss and looking at upgrading to efr9180.  it is a 1.05... one of my mate has a stock engine with efr8374. it has a 0.92 without the actuator. Tuned to 1.2bar and the car is great.

My current engine has poncam b, tomei rods and cp pistons (9:1).  the engine runs great so i am very reluctant to rebuild it.  As i am into hill drive, my main concern is response from the 9180. 

Do you of a dyno overlay to share? And maybe a vid of how the car goes?

      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).
