I scored the 13b I am going to port out a couple of days ago and I wanted to know what is a good E-shaft to go with? Stock or I think I have heard of a Guru 2 piece shaft that handles more RPM. If it helps I will be using the highest compression ratio rotors I can get (9.7) in a normally aspirated application. Thanx

How much more higher RPM?

I want 9-10k not too much



I don't know what the Guru will hold. I can't find specs.

I'd imagine it costs a pretty penny.

so do those rotors

Racing Beat's racing rotors are like 3K USD right?

They are pricey but you know what I don't understand? Renesis 13b rotors are $305.13 each!!! And they have a 10.0 compression ratio. If I was smart I would find a way to implement those rotors in by 13b rebuild. I know I would have to remove the blow by scraper seal. And the apex seals are smaller and lighter duty due to the fact there are no peripheral ports of any kind. Maybe we should make a new post about a renesis build. I know Judge ITO-san has much knowledge of the Renesis.

check the engine rebuild section; there is already a topic on this..

The Super Lightweight Rotors are $2200. The race rotors are under $600.
