Rb25det Carnk Collar

[MJTru]

hi mates

I'm building a new motor and i just got a crank collar, From the machinest point of view what does it take to installe one of these collars.?

Also with this new collar i'm using a greddy high flow oil pump, do you think that this will be a good set up for about 500- 600hp.

Around 8000rpms. I have red on this site that oil is what kills the RB motors. Will this setup be good enough? Looking at redracing the external oil pump set up is about 4k, but do i really need that, or will the greddy pump and collar work fine?

Lewis Engines has a nice little write up of what they do with crank collars: http://www.lewisengines.com.au/webcontent6.htm

An aftermarket crank damper like ross or atp is good for reducing harmonic vibrations that hurt your oil pump.
