My Mods List...What To Do Next?
Here is what I've done so far on my 91 n/a 5 speed:
-Weapon R Cold Air intake
-Air Box
-CAP Clutch
-Removed A/C, Air Pump, Spare tire,
-Wired Open 5th and 6th ports and VDI in high RPM position
-Strut Tower Brace
-RB Header and Presilencer
-Racing A SS N1 Spec single muffler
So, what next? I am looking at two different paths:
-Suspension
-Fuel
Suspension:KYB AGX Shocks, Suspension Techniques Springs, RB Front sway bar
Fuel:550cc primary injectors, 750 secondaries, Walbro fuel Pump, S-AFC
What to do next? Thanks guys!!!

I'd go with suspension, 550 pri/750 sec are a bit too much w/o any porting. Maybe 550 secondaries for now, but I don't think you need it yet.
You have a bunch of go-fast mods, but do you have good components to stop your ride?

I would get the RB suspension kit- it's pretty cool- sway bars and springs. about 600 bucks though.
You don't need any fuel upgrades. I have a ported engine, and I'm getting the most power by taking up to 10% off of my 460 injectors with my S-AFC!! No streetable N/A will need bigger injectors. (unless bridgeport at 10,000 rpm's- then it might need it)
The AFC is a good choice- you can gain up to20hp, but it's expensive, finicky to get to work properly, and you need a dyno and/or wideband o2.
An electric fan frees up a lot of space under the hood, and a bit of hp.
I would get take your 6 port sleeves out, and get the pinapple racing sleeves. They are real cheap, and work well.
Port your intake manifold- there's lots of pics here on that.
Get some poly bushings- and the rear-steer eliminators for the back- those really tighten things up.
#1- Fix everything that's broken first! (it's an rx-7, there has to be SOMETHING!) Clean injectors, etc. Throw on a few grounds.
I'll let you know when I get around to making that VDI actuator....

Former Moderator. RIP Icemark.
There is no advantage to using bigger injectors or a upgraded fuel pump on a NA until you get to the porting the motor stage.
In fact you will more than likely loose HP adding them to the set up you have now

Thats the setup on my car minus the S-AFC (I'm broke), and I run 12 psi

Short shifter? Wires? Body Kit? I want a fast car, not a rice car! j/k My shifter throws are short enough, I just put new NGK wires on a month ago, and a body kit?!?!? I don't own a Hon-duh!!! And the supercharger...NEVER!!!! Proud to be forced induction free! I plan on making this car the fastest I can! If I can get in lots of trouble with a little N/A, imagine how quickly I would be dead w/ boost!!
