TSX cams is a good start for a DD ride. Leaves it open for potential if you stay mild NA or go boost. You should outline your future plans now because going thru a few cams or valvetrains to support your desires will be costly.
Ifs helps but its not necessary. People have ran rbc and stock TB while getting 240ish whpdo you need to enlarge your intake manifold and throttle body to see any gains with these or any cams. I have basic bolt ons but don't know if the RRC/J35 is worth the money right now
