Welcome to NICO. If you are in a location that has stringent emission laws, I would definitely stick with the factory engine, but if you are in an area where emission laws are lax, I would look into a motor swap before modifying your stock engine right away. One thing you could do that gives you a bit more power but won't really be effected by engine choice is a nice cat back exhaust system. Choosing if you want to stay N/A or go Turbo early on helps with what modifications you go with as well. Some places to look at for parts can be Gspec.com (general FWD SR20 stuff) and BRMexhaust.com (for a catback). There are some other vendors (check out sponsors here on the forum) that carry some parts for G20s as well, you just need to look around as some sites carry parts that others do not. Good luck!
