I'm in the exact same position as you. Exhaust, intake but my my car is a 5 speed. I've decided to go with the turbo swap, so i'm not planning on doing anything until then. Right now, you could go for higher gear ratio in the rear end and perhaps and maybe a header if you plan on keeping your engine for a while before you do the turbo swap.

One thing you could do is to change diff to a LOWER gear ratio. You have 3.54s now , 3.70s will give you more off the line but any lower than stock , will lower your top end. 3.70s are from a '79 2 + 2 ZX and is a R-200 diff. You have a R-180 I believe , so you would need the moustache bar also . The R-200 is a stronger diff. . This is about the least expensive of a mod you can do that will yield more performance. I did this in my Z and it does make a difference . Gary
