What can I do to my 420a to make it quick(er)? I know turbo but that is later. I know Nos but I don't want to blow up my motor. Are there any mods I can do to this motor? Maybe even ones that will compliment a turbo later?

Sorry I am new to the import scene and it is hard to do a search on where to start with your motor. I also know there are probably 101 different ways to go, but if you could throw me a few or a general ideal. Thanks guys!!
