Hey guys I got a 91 civic hatch with a 1.5 non v-tech. I found myself a v-tech head and everything to make the conversion. How much of a hassle and I getting myself into with all the new wiring mods for the v-tech? And also I got the idea of maybe throwing in an underdrive pulley. I hear that it increases the rate of wear and tare of the motor because im shortening the belt route. Let me know guys. thanks

 

its not that hard, you will have to run wires to convert to MPFI, I think there are like four of them. Then you will have to dun wires for VTEC, and if your head is OBD-1 or 2 then you will have to do a little more work.
