Any B-series motor will work fine in your teg. since it's a 93 it's already obd1 so you don't need to do any obd converting . what you are gonna need is an ecu jumper (some one correct me if I'm worng)a vtec wiring kit(unless it's a gsr) and a p28 or other compatible ecu. you can use all the stock axles(unless it's a 98 spec trans with the big axles)(again some one correct me if wrong),mounts,radiator hoses, I think it has a few differences but I'm not to sure. Their is plenty of info online. you just need to search and find out what you need and what you can do. some other options are ,B20z,B20b,B16,B18C from a Gsr, you have lots of options you just need to look at what you want out of your car and think about how much you want to spend or put into it. Good luck.
some good places to check for stuff are xenocron,JDmshit,passwordjdm, or even local shops that are experienced with swaps and or tunning.
