The 2ZZ is a great engine but I don't think there was very much aftermarket support for it. Way more options for the K20 found in the Si. I don't think I've seen many if at all any 2ZZ that has broken 200 whp.
Welcome nonetheless. When/if you go to resell your car the cosmetic stuff (getting the dings out, detailing, and whatnot) you do will give you a much better ROI than any "performance mods" because that stuff is usually associated with hooligans who hoon their cars around and are hard on them.
