The VTC. Most will say 45* including myself, for a safety zone. Some will say go all the way, they've never had issues. I like my safety zone. K-pro is reliable, but accidents happen.
The k24a2 head when compared to the K20a2 head is almost identical. The springs are a little weaker, The high speed lobe is a little smaller. The K24 is built for tq. The k20 is built for top end. Swapping in a full k20a2 valvetrain with TSX cams will yield higher rev limits. However you will need the RSX-S oil pump as well to gain full potential.
With the RBC manifold, get at least a 70mm TB.
