1983 RX-7 Best set-up *NEED ADVICE*
 

Hey, so I got a 1983 RX-7 FB, and I'm looking for any and all advice on the best engine upgrades.

Here's what's been done:
Street Port
Holley Four Barrel carb
Racingbeat Header and Presilencer

If anyone has any ideas or suggestions on the best upgrades available and maybe even links to where I could find those products that would be great!
