Best Bang For Buck Mods
I've officially decided on getting an 86 GXL, NA. Its the cheapest one, and with only 60,000 km on a new motor, I can't go wrong. However, I need to know what the best bang for the buck upgrades are for it, in order. I've only ever modded a 4.0L Jeep TJ before, so this will be different for me. Do these things even have cylinder heads? I figured on a cone intake and tube, complete free flowing exhaust (headers all the way to tail pipe) although I don't know what dimensions to get stuff, or even which manufacturers to get it from! Help me!

Archive has a thread on upgrading n/as. Though I would say for the best bang for the buck you should get a T2 and mod that instead. N/As take a whole lot more money to produce the same power and have an upper bound of like 250, or something like that.

yeah if you plan to mod a rx7 sell the NA and just spend another 1-2k on a turbo 2. Then mod that to your wallets content. Modding a NA is like a dog chasing its tail. All that work and thousands spend and you find out you have a whopping 30 more hp.

I suggest before you do anything to the car read up on how it works. Theres no pistons, no rings, no valves, no rockers, no lifters.

thank you dDub
i enjoy modding my NA very much, everything in the car world costs money, maybe t2's are easier to slap on some bolt ons, and away you go, but building a fast NA seems way more rewarding.
--my two cents
P.S. to answer the original post's quesion i would do this.. and this is what i have done..
tune up (fuel filter, spark plugs, wires, etc etc)
weight reduction
intake
exhaust (header, straightpipes, good catback --- check racingbeat)
Apexi SAFC2 - get it tuned proffesionally - or get a wideband 02 sensor kit.
Porting (if you can afford it)
Nitrous --- i will be doing a 75 shot in the next few weeks here...
any questions feel free to pm me.
and guys.. can we please stop telling everyone who seems happy (and should be) about buying a NA rx7 that its a waste of time... i have had nothing but fun with my car.. i think it is total ignorance for people to say this..
at the end of the day.. they are both rotary's, which we all know are beautifull cars.

i think building a n/a is just as fun as building a boosted motor i'd love to have a t2 in my engine bay but thats not going to happen til this one goes so til then i'm happy with what i got .. just as much as any other person should be . and to build a n/a is rewarding in its self a n/a will pull many things with just intake/exhaust work and a good tune-up,etc. my lil 2cents have fun

no gains for a wideband, but it allows you to tune for better performance (i.e. SAFC). Kits can fun as little as $300

You want to start with preventative upgrades, such as an aluminum radiator, stainless steel oil cooler lines, electric radiator fan, custom ducting from front of car to the radiator and oil cooler, etc. Then you can start playing with performance mods...
Basically, the intake and exhaust are the more restrictive, as well as the more easily modified / replaced. Find a nice cat-back exhaust that you like and go with it (most people reccomend the Racing Beat system, but I say the GReddy Power Extreme is the way to go, sounds so much better and looks so much meaner). Intakes are basically the same any way you go. DO NOT GET THE HKS INTAKE-it is the more expensive and filters MUCH less than even the Ebay filters. The reccomended one is the Apexi intake because it filters the best and allows up to 2 more HP gain over the HKS system (whooptie doo!). Beyond that, headers, porting the throttle body and intake manifolds, as well as cleaning the injectors, and you have pretty much eaten up the bolt on mods. Beyond those, you have but a few options: Stand alone EMS on stock engine or port the engine to your hearts (and wallets) content (i.e. street, 1/2 bridge, full bridge, peri-port, hybrid peri, etc.). Do some research into these setups and find one that you think will fit your needs the best.

The Cause of Death
search the archives for a thread about "beefing up an n/a" or something like that
here's what i did:
stiffer springs/shocks
wheels/tires
intake
exhaust
coming up: LSD in rear, stage II clutch (ACT street/strip), lightweight flywheel, and hopefulyl tII drivetrain so that one day i can do a turbo swap and not worry...
i think it's fun modding these cars, although the power output will never be that of a turbo car, it's still nice having a car that can give you, your passenger, and the two ricers on your sides a little kick in the ***
good luck with it

However, I agree that the false conception that an NA RX-7 has no performance value is completely ridiculous. I am still waiting for the turbocharged RX-7's to rack up HALF as many racing wins as the NA-powered RX-7's. Even after over a decade since the end of production, there are still more road racing classes for NA RX-7's than there are for turbocharged RX-7's. I think that pretty much sums up the performance debate.

Is it just my imagination or is it mostly the T2 guys that are here all the time with blown motors, turbo's leaking oil, detonation problems, smoking and various other problems. I am under the belief that a N/A motor is considerably more reliable and will last a long time if proper maintenance is preformed, to that end a few dollars spent to beef up a N/A that will last is much more cost efficient than building a T2 motor over and over again.
don't get me wrong a lot more horsepower is fun but there is a place for the "lowly" N/A and I happen to like to know that when I go for a drive my car will get me back home and the N/A community seems to always get back home to run again.
Just a few casual observations....T2 guys, flame away..........

Apexi SAFC2 - get it tuned proffesionally
arent these a bit pricey?? nevr really looked into them really. i live about 2 hours from erie(i know sucks to be me) so if i did decide on this i dont even know who to go too around here to have it tuned. what kinda gains can you achieve, do you gotta get bigger secondary injectors?

i know right, my 88 turbo II is pretty fun, and very fast but i enjoy n/a engine vehicles, i think it is mostly in the engine response or something, but don't get me wrong I enjoy the turbo power so i'm gonna mod mine up and if im happy with it then i'll keep it, if not im gonna sell it and get an n/a (probably 1st gen). i think a 1st gen with a turbo engine would be alot of fun, or a 3rd gen with the sequential twin-turbo setup. I probably shouldn't say that in the 2nd gen forum section, but i like all rx7's and i miss my fb.
oh yeah, forgot to mention...header and loud exhaust is alot of fun!!
light weight flywheel depends on your personal opinion, alot faster engine response but less rotational mass, it makes it easier to drive without the clutch.
