I'm building a b18b turbo for a crx, with the main goal is to getting into the 12's. I know their is a hell of a lot of situations on the exact number, I just need to know at around what horses should I need to get a 91 crx si with full interior in the 12's. Nice pair of nitto 555r's, stiffen up the back suspension, and loosen up the front. Maybe even throw some wheelie bars on the back to hold the front die for better traction. It's a pretty mild build, pretty much stock block, mild port job on head, skunk2 intake mani. And not sure on the turbo, i'm figureing some kind of 50 trim. I'm from the dsm community and tired of that crap breaking all the time so whats a good size turbo for a honda. I figured around 250-300 horses to get into the 12's, does that sound right. Also I was wondering why everyone vents their bov to the atmosphere instead of recirculating it back into the intake. Are their certain year hondas that have to or do you guys not have a mass air flow sensor? Just wondering, on how I should go about it.
