ok heres the deal i have a 94 civic dx 4door that has been striped of every thing but the dash and the driver side seat. i want to use a big power plant in it but im having a few problems. for one its auto( eeww auto sucks) and i have no idea on how to make it a 5speed. second what about the wiring harness will the stock harness frome the d15 work on the h22(i mean it worked on my rex when i did a swap in it so i was just wondering) or will i have to get a new harness made.
