I am calling around to different places for prices on B18C1s. They are asking me USDM or JDM. If I am correct , there are a few differences in the two such as wiring harness etc? any others? also, if I go USDM, where do they get the engines from? Do the engines come out of crashed cars? Is it safe to go the USDM route in fear that the car was in a bad carwreck. Sorry if this is a n00b question, but I really dont know. Thanks Which would you prefer?
