ok guys, as most of you know, i have a 94 B18C1 in my rex and ive decided to go supercharger, only because i want to have headers and intake still, and its instant power, ill mostlikely get jrsc. now im also planning on getting the jdm ITR 4-1 header for my setup. i will replace my mounts for the hasport billet mounts (gen2). now what i want to know is what will i need to get everything to work. do i need more o2 sensors? what do i need as far as a catalytic converter?, and where can i get one for my car? (i would prefer a high flo cat), and most im portantly will it all line up to my stock exhaust? i do not want to have to modify the exhaust or header. if it doesnt what will i need to get it to line up? any help is appreciated. EDIT: on a side note, with a supercharger setup, what should i get as far as intake manifold, cams, pistons, rods, vavletrain, etc?
