hi guys been reading a few threads regarding supercars on here,
although i own a cos which is a garage queen i dare'nt push it to its limit
i was well into the e30 bm scene not long ago and had a turbo'd m20 2.5 pushing the shy side of 400rwhp

but seein some posts on here with claims of people keeping up with these supercars with there 330bhp cars ect has made me think if its really possible to do it on the cheap?

im in the process of comlpetely refurbing a 325i sport so might be tempted on another turbo conversion

guys opinions and figures please and be realistic thanks
