In Japan the DA's came with a B16 (XSi) but the main difference was weight. The JDM counerparts did not have all of the heavy US crash standards and therefore a B16 was a good engine to have in them. I will tell you this from expierence, I have a friend with a B16 in his teg and we run neck in neck all the time except on take off and I can pull away from him there (torque) and then the higher rpm allows him to catch up and then it is pretty much even. Do as speedminded said and get it, then later on get you a GS-R block and have a poor mans ITR.
