I don't care about that. I'll go standalone fuel and ignition management. If the VTEC is electronically controlled, I can go that route as well. But, as far as I know, Honda never made an EFI 3rd Gen wagon in the States - there won't be any EFI fuel tanks to swap period. I'll have to use a surge tank and inline pump. Bike carbs would be fine too, I just don't generally get along with carburetors. And my wagon is a California emissions car, so it has about 50% more emissions equipment on it. Having the stock motor simply replaced is guaranteed to be a maintenance nightmare. Will a D15B head bolt-on? There's a lot of conflicting info out there. As far as I can tell, only an '87 Si head will swap to the stock shortblock.
