Rb30 Crank Modifications

[BlownNBoosted]

Since it seems I am keeping my new setup. I am looking at upgrading the specs of the internals that I havent changed.

My question is since I am using a standard Rb30 crank what can I do so allow better high rpm, strenght and oiling.

Thanks

PS: I know they are already nitrated so I will only get it cryo-treated

Does everyone leave the cranks alone?

only thing i've seen and confirmed is the addition of the JUN style crank collar from JUN or proengines to allow the fitment of the r33 rb26 sized oil pump

Things done:

Crank Collar

Balancing

Im thinking of

Knife Edeging

Grub Screwing

Balancing

Cryo treating

isn't knife edging only for N/A revvy engines ?? to reduce the rotating mass?

It is to reduce mass and also drag but id like to know what people do when aiming for 500rwkw with an RB30 bottom end

Knife edging makes your crank cut through the oil easier. When the counterweights on your crank hit the oil you get a bit of power loss and it creates foaming of the oil.

Knife-edging will reduce power lost from hitting the oil and also takes off weight from the crank.

something like that anyway!

Cool, any others?

a billet crank cradle(spelling) ask sydneykid i think he knows all there is to know about RB30s .

I want to use the factory bottom end as far as crank, girdle and block are concerned. I know it can be doen just want to know what they do
