i wouldnt call it a build, its a bolt on turbo and cams, injectors and a tune. hes a member on this forum, hell speak up if he feels inclined. the point im trying to make, is for you to MAKE any power out of a rb25, your going to spend 3 times or more what it would take to do an sr. i dont know what the general accepted "reliable" hp is you can make out of an rb25, but i know its not much more than 400-500. which makes the swap completley overrated to me. im just tired of hearing dreamers talk about something theyll never have. really though, 12 psi on a rb? just tell me what the point is? it wont make anymore than a bullshit t28 setup on a sr20 can. if its so you can SAY you have an rb, then i rest my case, its a fan boy motor. theres no real reason to go rb. waste of money. and before people on here give me that "you can buid it" bull shit, you can build anything, including the sr. i dunno, im just ranting. i really dont understand the whole rb25 thing though.
