I have a 92 honda civic dx 4 dr with a D15b7 I know it suck's :disappoin
I want to put in a b16a2 it comes with 5spd with the ecu but i dont know if it is obd 1 or 2 and how hard would it be to wire it up thnxs :biggrin:

obd2 and the wiring isn't that difficult, just have to wire the V-tec solenoid into the wire harness. (I think, I may be dumbing that down a bit)
