I have a 92' Si Hatchback. If i go onto hmotorsonline.com and get the 94-95 GSR complete changeover package for $3149 will i need anything else or have to "modify" anything for the swap?? I have a guy who can replace engines but wouldnt know the little knick knacks that sometimes come along with honda swaps. I can also just plug the P72 Ecu that the package comes with right into the Si harness right?? I just want to get everything straight before i buy the engine and start the project. Also, if you could answer the questions for a B18b also?? I see that this comes with a P75 Ecu so what would be needed for this?? Thanks for your help in advance.
