Good to see this kit available at last! Have to say 450kw is somewhat underwhelming but the extra capacity will have to translate to more power. It will be great to see someone build either a drag or a circuit car and see what it is really able to do!

please note this is on pump fuel with a rb25 head

another note is that the builder needed to get a new clutch because of the extra torque

hope to build this in the future.

I am sure it is capable of much more. The 3L going into my Stagea is looking too small already!

Its a sad day when 608hp/450kw doesnt impress.

That said, im sure Brad couldve got a T51RSPL on there at 2 bar on e85 if he wanted a big number, surely the point here is just crazy low end grunt more than a big hp number :)

yeah id like to see the power curves on this engine.

he was making close to 580-590hp with the 3.0l so this is a great improvement especialy how it is relativly cheap comapeared to a full house jap bottom end.

probly total cost for the whole engine is 6k - 10k by guesstimation.

There is a price at the top of $5500 for the rolling assembly so you would have to say closer to 10k all up ready to go depending on how far you go.

RB34DET Results

RB34DET 'vs' RB30DET

The RB30DET boost and power curve is in green and the RB34DET is in red

Resize%20of%20142JHK%20power%20vs%20boost.jpg

A comparison between the old RB30DET engine and the new RB34DET stroker engine is complete. The two engines are identical in every way except for the new stroker crank set up. The purpose of building two near identical engines was the only real way to make a true comparison between a RB30/25 and a RB34/25.

We arent trying to make the most power or we wouldnt be using pump fuel and a medium frame old school T04Z, we are trying to make a comparison.

Straight from the horses mouth.

    • 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).
