look at the FMAX and RevHard kits as well they have applications to fit the b18 in a CRX. i have the same setup...i have a B18 with a Turbo in the works and i am going custom personally because i am lookin for the sam WHP as you or more. i am going with the Turbonetics T3/T4 turbo to start and then i am going with TurboX's BOV that has a toggle switch to go from a race BOV to Street BOV from inside the car. but hey make sure you find out what you want. and it will cost a little more than 5k if you get ALOT of good parts that will hold up well but it can also cost less if you get some good parts adn some cheap ass parts but thats just my
