Man those vids are schweeeet....... quick question thou... Any thoughts on how the KKR430 would perform on a RB25? You say the boost is great on the RB20.....just wondering if it would be a bit laggier on the RB25.....??

I would of thought it would be less laggier. Though i think the KKR480 would be better suited. I think Otomoto state they have gotten 260rwkw (could be wrong lon this figure) from the 480 on an RB25 neo

Thanks guys, yeah was a typo with the KKR480 / KKR430. IObviously the KKR430 would be less laggier on the RB25 as it is a smaller turbz on a larger engine....

As replicate answered (cheers champ) was wondering about the KKR480 on the RB25 in a bit more detail than what is listed on their site....

KKR-480

Suitable for larger 2.5–3.0L engines, this turbo features a twin-entry T3-size exhaust flange, which is also suitable for normal T3-flange manifolds such as RB25DET or RB30ET*. Rated at 480hp, it uses the same compressor design as the KKR-430, but a larger turbine and housing better suited to high-boost applications up to 20psi. It uses a 2.75in V-band flange for the exhaust outlet.

Tested by Croydon Racing Developments on an RB25DET Neo engine, it produced 242kW at the wheels at 18psi. The standard internal wastegate is designed to hold 14–15psi.

Just trying to establish if the is much modification required to fit the KKR480 to the RB25 as there is for the KKR430 to the RB20.......

Pay an extra few $$$ and get a straight bolt-up Garret.......

Oh well such are the dilehmas of the 'turbo game'

    • Bah! I can't see the point in custom number plates at all. I went to the rego office, fished through a box of "premium" plates (the ones that had the "not as tall" option for the front plate) and picked the one that had a 32 in it. That's the limit of the effort and cost I will put into number plates. The only plate that I'd consider paying for would be 2332, but that's not possible here because it already exists from probably 90 years ago, and it would cost a fortune to obtain it, if it were available.
    • After chasing my tail with LS results..... and cheaper than a turbo swap... How confident are you that the dyno is accurate relative to other results? How fast is the car - What MPH does it actually run? Is this similar to what people running this power would expect?
    • Hi mate I am having an identical issue with my 98 R34 GTT. The engie suddenly cuts out under load at about 3-4k, black smoke out exhaust. Almost feels like traction control kicking in. No CEL but still going to check codes later today. Car was sitting in the shed for about 5 months before hand and only idled a few times, took her out with about 1/4 tank, filled up and thats when the issues started happening.  Threw on a spare set of coils/harness and checked plugs which was no help. Recently had fuel pump/filter changed so surely thats not the issue unless condensation in fuel, I just havent had the time to drain it It's running a hi flow turbo, bosch 1000cc injectors, walbro 450L, Z32, Nistune etc... All about 2000km old.
    • I always wonder where the obsession with legal/illegal spacing on number plates in the UK comes from. Because it comes up in comments in every UK-based video I see on youtube. From my point of view all of your plates look a bit odd. Just because there are no markings whatsoever. In Australia we have the state that has to be on it. In Europe you get stamps and state logos. Yours look a bit like a throwaway draft that people then stuck with. And attached with blu tack so that it falls off at the slightest disturbance. Not trying to hate, but it's interesting how things are done in different countries. Do you have to follow a lettering convention when choosing a custom plate?
    • Hybrid sounds like a supercharger... It's half a turbo, with a belt to drive it! Oh wait, they're just called super chargers...
