RX8 E-shaft vs 13B-RE/REW shaft

Buggy · 10-30-2010, 08:46 AM

I have the Rx-8 shaft in my Rx-4's engine along with the Rx-8 stat gears and bearings. This is an NA setup mind you so I'm not really pushing these parts to their limits. I've got probably around 6000 miles on this engine with no problems of any kind. Runs great, still builds good power and wicked oil pressure. I don't know if there is any real significant gain to going with the 8 shaft, but lighter is lighter and cheaper is cheaper...... Those were good enough reasons for me.
