well it all depends what car the other motor came out of cuz 1.5 single vtecs can be found in crx's old school civics ..etc.. if thats the case thenall you would have to do is change a few plugs from the injectors and the distributor that you can get from your wiring harness on your old motor. but you would still have to run a vtec wire to the ecu... most people do it directly from the vtec solonoid to the ecu. but if the motor came out of an eg (92-95) like yours, all you would have to do is run the vtec wire. if you would need to do ANY splicing which i highly doubt- but theres some wierd sh*t sometimes- it would have to be the fuel injector plugs and the distributor like i said before.....but its HIGHLY unlikely. but good luck man.....and i see on your list your missing a couple things but you just might have forgotten...but the axels the mounts and the shift linkage...and youll need to change your ecu so your vtec will pop
