WOW, lots of smart ass comments not one bit of usefull information. First off I would imagin your car is a 1.8 DOHC, I wouldn't know because you don't give much info. Anyhow, the BOV is not really a key issue you are going to have. Depending on what turbo you are going to run you can size that part of the set up. Wastegate is also determin buy your turbo and what type of header/exhaust manifold you are going to run. Is your turbo external gate? I ran a T28 on my car. Internally gated, I ran a FMU with a MSD high pressure fuel pump. The car with a FMIC was at 10psi. I eventually whent full standalone EFI with 550cc injectors. I turned the car in boosting 10psi daily and 18psi as a high boost setting. Get me info on what parts you have now, what you are planning and how much you think your going to spend. Good luck with that thing.
