I read on a thread one time that it was smart to go H-seires because going back to B-series or D-series would be difficult. Is this correct?

Please provide some info.

If you're going to say search give me a specific topic to search please.

H series to B series brings up 548 threads.

 

I did it on mine(00 EK) but you have to prepare the car thinking that you're going to put back the D16 in the future. I built a separate harness for my H22 swap. When I went back to the D it just only took me 2 days by my self.

 

on the 92-95 civics you had to cut a piece of the the mount location for the h22 tranny to operate..then theres the cutting a hole where the shifter goes.. most any welder could fix these things up pretty quick
