Sort of. It just makes sense to me to go with the 8cw crank vs the 4cw. I already have the Tomei rods which are lighter and stronger than stock. The better crank with all new bearings and rods means I'll have a solid bottom end. If I am already there, it makes sense to go with the N1 pistons and new rings. I already have a worked head and intake. I have a set of N1's in it now and I have a set of 20v's in my possession. I can play around and find the best combination for the most power from 4/5k-8k and it will be plenty of fun on the track. It may not make the most power, but I'm not that guy anyway. I just want to have fun and I'd like to do it with out breaking the bank. The only parts not in my possession are the pistons and I will be way ahead even buying those after selling the crank.
