Now see I have never removed my inlet pipe to do the plugs.......its - like kinks said - doable without too much trouble.

A socket that fits is wwwwwwaaaaayyyyy cheaper [say $100 max] than a ffp and all that hot gear your looking at. And now that I've reduced your mod costs by $1000+ you can now afford that flash new turbo.

And as everyone says 300rwkw is more than achievable with the std plenum, there are people on here with a fair bit more than that and still running with the OEM.

Run bcpr7eix @0.55mm and plug changes are literally non existent (tri yearly operation..) factory plenum works fine into the high 300s.

GT3076 0.82

or hypergear G4 SAT

A GT35 will do 400rwkw on E85

So a fair bit further from your 300rwkw. It'll also be well outside a lot of the other parts you've already fitted.

Stick to the "around" 300rwkw, don't go for more.

Can confirm factory plenum (at least on R34) is good for well over 400+

The difference in ACTUAL speed of a car is really not much AT ALL between 300 and 400 due to soooo many other things suddenly becoming a variable. A punchy as possible 280 is what you want unless you are willing to go full retard. A bolt on, IWG solution is the smart solution. Spend the rest of the money for your build on making the thing turn, drive well, stop, etc and you will have MUCH BETTER CAR.

That atr45sat, that's the direct Bolt on for the rb25det? And if I'm not mistaken that's close to a gt3582r? If so I've chosen my turbo :)

That is a direct bolton turbo except u will need induction pipe and a silicon elbow plus 4 longer manifold studs. power level is close to a 3582 but similar response to a 3076 in .82 rear.

Well I've planned to put 1000cc injectors, walbro 460 fuel pump when I do the turbo anyway but I don't really want to touch the internals just yet so I don't want to push 300rwkw too far and it's just had new fuel lines put in it so should be good to run on e85

I also am running well over 300kW on the stock plenum and also stock exhaust manifold :)

No need for fancy shit, save that money for rack and tits

Isn't time a funny thing... 10 years ago, people would point and scream liar at a 300kw rb25 with stock manifolds.

Rack? Or Crack?

E85 was readily available here that's why, water meth boys did 300kW+ though

    • 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.  
    • 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       
    • 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).
