Next week I'll likely start with my tuning. I'd love to have a discussion on how to best lean out a K series motor.

My build has worked out to:
-JDM K24A2 (K24A), 05 with 08 intake cam
-K20A2 oil pump - no countershafts for reduced weight and friction
-50 degree VTC mechanically limited to 40 degrees, since my engine is an 05 with 06-08 cams - the reliefs for the valves are smaller in the Pistons
-10lb flywheel
-TSX magnesium transmission for weight savings - NOT recommended for turbo since it's more fragile
-3.4 final drive (custom)
-0.647 6th gear from a '12+ Civic Si
-Honda OEM LSD
-RSX ECU with KPro
