are there any parts from other toyota engines that I can swap with the parts from my 2S-E to possibly get more power? any heads that are swappable or whatever? i'm not very familiar with this engine, but i do know it only has 93hp. even though, it is pretty quick and considerably torquy. i've never gotten second gear rubber so easy (switched from a sentra w/ 1.6L). thanks in advance for any help.
