I'm still learning the ins and outs of this great car so any information or advice would be greatly appreciated.
Thanks in advance.

I would wait till you get a good header to maximize your gains. By good header I mean any of the following:
ACE
HKS EL
Tomei UEL
JDL UEL
And also consider adding a front pipe if you want an extra 5-10 whp.
