The chip is the last to do, upgrades to motor should take priority honestly.
And an easy/reliable way to make power for about $4k or less is a s/C kit from a Lotus setup (Lotus talk.com). I have installed one on a past 2zz I owned and they are VERY fun and powerful. If you get an OEM kit, should net you about 250hp, if you net an aftermarket setup, it should net you about 350hp...which in a 2zz is a blast.
Install is really easy...took me about 5 hours in my garage, and all in all should be darn near identical.
