NA, Vtec, Turbo or Charge. What should i do with my B20?

dont listen to pdiggity... you cant rev b20's anywhere without internal work.
depending on your budget, bore/resleeve
get a vtec head and intake mani. (and you cant just slap on the vtec head and expect it to run correctly, you have to do a lot of machine work. ie, plugging oil holes, boring combustion area, boring out head gasket, ect. check this site out http://www.b20vtec.com/frontpage.html
rods, and forged low compresstion pistons if you wanna boost it, gsr (or ctr/itr if you can afford) cams,
steel crank
that is a good start for b20/vtec turbo let us know what you decide
