Newbie to the K platform, I have an S2000 F22C endurance road racing car. Looking to do a K24A2 (2006-2008 TSX) bottom end and K20 Head. Looking for most power and torque with reliability. I have the option to get a K20Z4 RSP-2 head/cams or K20A2 PRB-1 head/cams. Will be replacing rods with Carrillo H rods or Saenz 300M and pistons with Darton sleeve. So my question would be what would be the best combination for a road racing race car. The car has Haltech Elite 2500 running E85. Looking for 300+ WHP. Suggesting from the experts here what would they use. Thanks in advance to all.
