Okay guys so I got an 03 rsx cheep from the wife's uncle it's a base model with a k20a3 motor 5speed tranny... Was wondering if I bought aftermarket rods,pistons,rings and bearings and built the block... and then bought a k20z1 head and built that would it be worth the money ? Thanks in advance !!!

 

Better off building a K24 block, or just get yourself a complete k20a2 swap.
