anyone asking these questions can't possibly have an 800hp twin turboed e30 m3. post pics. stop using more than one post for the samething. and there is no way to have 250 hp on a naturally aspirated "e" motor. where is this shop that built your m3? and how come you don't know about turbos after building a twin turbo car? how come you can't prove it with pics or dyno sheets or drag slips? how come i think you are full of it? wait you are, i get it now. all that lying made it impossible to tell the truth.
