they are startin to rhd on d17 motors and is it worth fully buildin my d17 high comp pistons full valvetrain so on and cams /i/h/e or just save and drop a k20a2 and build that i would drop a b16a but it wouldnt be legal

 

I think that it is worth it to wait on the developed parts for the D17 because to do a K20A2 swap is very expensive... (not saying that a full valvetrain setup isn't) but it will be worth it..
Crower is currently doing a full R&D for a full valvetrain & botton end parts for the D17's
