i think, that if yu are gonna run turbo save sum money, dont bother with VTEC, just get a B18A or B18B they are same block designation as the B16 and take the same size.Wut are yu putting this in again? Anyway or go with a 89-91 B20A frum a prelude. The issues with VTEC and turbo is that with out a particular cam for VTEC when running turbo application on a VTEC engine yull might get problems. Trust meeh ive seen this, regular aftermarket cams will worsen the issue if its not made for a VTEC turbo, in VTEC range yull get a sgudder and or multiple cylinder miss, because, these cams and sometimes the stock cam will do it also but rare to none, is adding to much lift to the intake valve while in VTEC range thus fore the valve not keeping all the compression in the cylinders(seeping out thru intake valve back into intake)This would not happen if it was N/A application but can happen cause turbo is compressed air forced into the cylinders.If yu run turbo get turbo specific cams
