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!!!

Any help?

I would say if the fuel isn't a necessity right now, that you should get the suspension first.

Put the spare tire back. Walking sucks.

fuel's only good with a port & better chip. Otherwise no power gains (actually some loss from running rich).

Very funny Felix!! Anyone else? Or if you have a different recomendation from other than what I am thinking, please share!!

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?

Oh yeah, good point! Any ideas for brake upgrades?

well if u go for bigger brakes ur need bigger wheels... and if u want REALLY BIG big wheels then ull need a wide body kit up front.. but if u get a wide body up front ull need to kit the WHOLE car so that the look flows better... then if u get ect ect ect.. LOL :D

Hawk pads, and good tires. I wouldn't worry about slotted or drilled rotors, IMO, I don't think they're worth it.

dont go with bigger injectors... an n/a does not need them.. i was stupid back then and got t2 injectors for my car.. i noticed a slight decline in preformance and the only time where it felt better was above 230km/h so... dont even bother!!! go with suspension... upgrade what rx7's were made to do!!

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....

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

lmfao @ Put the spare tire back. Walking sucks. your damn right it does, whats even worse is when you have the spare but no jack

Re: My Mods List...What To Do Next?
 

You won't need any fuel mods at all.

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

hawk hps pads, ss lines, shocks/springs. some bushings if you don't mind the work!

Well, I am getting the KYB AGX shocks package. Then the RB package, then the S-AFC. Thanks guys!!!!

Don't forget the TB mod, it's free and good for at least 5 HP, plus more responsive!

shocks ,springs ,short shifter,
spark plug wire ,body kit,how about supercharger.....

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!!

leave the stock injectors and get a Safc, that is all you need. Fine tuning what you have should be first.
