Look on the main page of this website, lots of people run B series in their civics. Plenty of info on this swap, just have to do the research on it. Let us know if you need help in a specific area after you have the bases covered.

Re:GSR engine in a 91' Civic Si
The fuel system u have will be fine for just n/a engine applications, but if u decided to boost it like cheesefrog does u will defintely need fuel system upgrade....now the gsr b18c1 i am assuming we are talking about will fit into the ef chassis, just need b-series mount kit, cable tranny out of a b18a, or b16a(ys1, s1, y1 etc) then modified integra shift linkage or shift linkage kit from hasport, or someplace like that...if u get a integra ys1 or s1 tranny then u can use integra axles from autozone, or discount auto..make sure they are not the abs axles, u will need the non-abs axles they are different.Now for the ecu i believe they come in obd-1 and obd-2 and is the code p-72...so since ur car is obd-o u wont be able to use, unless u get a obd0 to obd-1 conversion harness or u can just use a pr3 ecu which is for the b16a...that ecu is 0bd0...other then that u will just need micelaneus radiator hoses since the d-series hoses are to small diameter compared to b-series, u will need upper and lower rad hoses....that is about all i can think of right now...
