mikey just to keep you in the right direction - aim some pm's to members on this forum for similar experiences...a d series turbo will take ALOT to get to 250-300 whp. If you want a faily quick car just chuck on a turbo "kit" IMO. It will net you maybe 120kw (160 or so hp) atw , and give you a fun car for the 1/4 and daily driven.
