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'

    • Something to note, on an aftermarket BOV, it's quite possible to end up with the worst of both worlds, where on light throttle, there isn't enough force to open the BOV so you get small reversion and driveability issues, and with the venting to atmosphere, it dumps a lot of fuel on shifts. Realistically, dumping to atmosphere under power isn't a major driveability issues, compared to the issues of stalling from reversion. If you're getting up the throttle, then putting the clutch in, say on a shift up, but then don't release the clutch, yes, the engine can and will stall, but, just drive around it, and that's easy, let the clutch out in the next gear and the car rolling will keep it all running / going.who wants a hard hit of throttle and then to just let the motor idle anyway?   Main issue for driveability is blipping throttle and it wanting to stall, like when parking or trying to move in slow traffic.
    • As in they quoted one price, you mentioned the exhaust, and they promptly added $200 on top? Interesting.
    • Note that I'm not suggesting this is a great idea. Just saying that it is something that could be done to achieve a better outcome than the more shit ideas will provide.
    • I'd try removing it, connecting hoses and see if that helps. Depending on specs, it could actually be restricting the flow(it also might be helping).
    • Yes, that's a hybrid BOV. The adjustable spring load ones are about making teh pressure build up higher before venting, so you get a more agressive whoosh. That is not what I meant or what you want. By "restricting", I don't mean "keep it closed until the pressure is higher, then open it fully". I mean "open it as soon as it is required, but only have a small port area, so that the flow rate out of it is slowed down". The pressure will rise to be higher than a bigger ported BOV would provide, but it would do while it is venting. The idea is to slow down the rate at which the replacement eair is flowing past the AFM, to reduce the magnitude of the air flow signal peak, to reduce the amount of fuel that is added per revolution.
