noob questions. Are all B-series engine mount positon the same? For example a B16 from EG6 will drop nicely into EF9 chasis? The reason being I am able to get a EF9 half cut and I want to drop in a B18B engine (94-95 (LS) Long Block). Yes, I know it would be better to use the B16 instead. But due the strict law in the country against swapping of engine, I figured that since B18B has the valve cover design as my current D16A9(88-91 CIVIC SI Asia), therefore a lower chance of being caught when the local authorities decides to pop my bonnet.
