I talked to some guy and he told me that due to emissions over in japan the majority of the motors are carb. He also said if an engine is really a jdm it wont have a # at the end. I.E. d15b7 vs d15b being jdm version. He said you would just take the carb of and attach your intake manifold and would be good to go. Is he right? I dont think i ever heard of a carb b18b or b16.
