u can either piece it together or just get a bolt on kit....the bolt on kit may be a lil more expensive but ur guaranteed everything u need (turbo, intercooler, pipes, lines, fuel system, engine management, etc....). then u can save for a good tune. if u piece it together its not guaranteed that everything u get will work right with ur other components. ud better do some research before u go buying whatever parts u want. i agree...get the right sized turbo. dont cut any corners and for the sake of ur pockets (and motor), dont run untuned bc itl blow sooner than u think! i cant tell you how many ppl ive seen blow up a honda bc they tried to run it untuned. u can break it in on a basemap and then get it tuned so it lasts longer and puts down the power u want. take ur time with it...ur more than likely going to put down between 250 and 300 hp to the wheels after its tuned. that depends on how agressive the tune is as well. make sure every thing is taken into account before u go boosting ur b series. they are naturally all motor cars, so throwin boost at them may be easy, but its not what they were designed for. just make sure u take EVERYTHING into account before u do this.
