hear is something they sent me when i emailed them
Hello Scott,
The KKR-480 is $899. We also have a dump pipe available to suit the RB25 for $149 (suits standard or aftermarket front pipes).
To fit it on an RB25 you need to rotate the compressor housing and actuator to point the right way. The actuator rod also needs to be bent and adjusted to suit, while the compressor housing needs around 2mm ground off at one point, where it is too close to the exhaust manifold. You will also need a different bolt for the oil feed and a 2.75-inch V-band clamp. We have a mobile mechanic in Sydney who does the complete installation for $520 including the clamp.
We recently fitted the KKR-480 to an RB24, which made 256kW at the wheels on 1.35bar boost.
Here are some more specifications:
