So im going to swap in a B18b in to my 95 civic. and i need to know what to do for my intake. Do i just modify my stock airbox. or do i use a b18 intake. im gunna n/a for awhile just the norm(intake, header, and maybe port). Then go turbo but that wont be for awhile.... And i have a auto. So should i swap to manual first before i get the engine? Or just do it while im swapping in the new motor? Much thanks
