Hi, Great site ! I just acquired a Civic Ferio VI-RS from Japan, which is a 1.5 litre with 3 stage vtec, engine code is d15b, which should be giving out 130 ponies on redline. I have 2 motors to my availability, a B16A1 and a D16zz ( a 1800cc sohc vtec). Any ideas on which one should be easier/better/more recommendable/easier. Also, how about a supercharger on the stock motor, less hassle, enough power for me. which one, any brands ? Thanks a Lot. Pierre.
