help swapping a JDM b18b into integra ls!!!!

I have a 95 integra LS b18b1, got my timing belt broken and people were asking me like $800 just to fix it an make a valve job, so I decided to get a new engine. Now, I just got a b18b engine straight from japan, with less than 40k, but the guy who is making the swap says that the intake manifold for the b18b is different than the usdm b18b1, he says that there is sensor missing (mac sensor) or it doesnt needs it, and the guy is blowing his head installing the engine. Has anyone installed a JDM engine, so I can have some suggestions?

uh wouldnt the 800 for repair been a lot cheeper than the cost of importing and installing a whole new engine, and why didnt it come with the intake mani. my swap came with intake, exaust, trans, axles and ecu. oh and can you tell us what mac stands for
