The only thing i have right now is the long block (k24a8) with A4 TB. If i go with a 5 speed accord trans, which engine harness and ecu will i need? If i go with an ep3 trans, which harness and ecu will i need? PLEASE HELP I've been researching for months on my kswap now and keep going back and forth on what to do. I know im going ep3 trans or accord trans.
