I'm actually in the process of building my b18b motor for my LS integra im looking to go FI. I just ordered in a set of Eagle H beams slotted for gsr bearings and im looking at pistons now. Arias looks good but ive been checking out Endyn roller-waves and they look magical. Im wondering if anyone has had any experience with endyn roller waves on an FI b18b and also how reliable they are. Any input would be much appreciated.
