Reliability Is The Factor...period.
Ok so i have been reading on the different mods to do with the efini twins, bnr's, apexi single, etc...And we all know the rotary engine is not the most reliable engine built ive faced with that fact already, what im looking for in this thread is the reliability factor, what are the limits? Ive read 300rwhp and ive read 450rwp now there is a 150 difference there. I know if i get 500rwhp the car is gonna get at a stoplight and die, it wont idle worth a crap. What i want is a reliable but fast rx7. What boost levels are too high? What turbo's or turbo to go with? Is streetporting exceeding the limits? If it helps any i plan on have ASpec tune it since there the best i can find that's close to iowa.

If it is Fast & Reliable, it ain't cheap
If it is Cheap & Reliable, it ain't fast
And if it is Cheap and Fast, it sure the hell ain't reliable!
lol
This probably didn't help much but I love reciting it.

Reliability is neither a line to cross nor is it consistent in nature. One car might break down repeatedly for no reason, while another could go 100k without a problem. It's not like 10psi is fine but 14psi is bad. For a long lasting engine, keep the intake air temps down, the engine well cooled, do good maintenance, and give 10 minutes at the beginning and 5 minutes at the end of each drive where you don't flog it.
If you try to analyze it deeper, you'll get nowhere. IMHO the way to go is slowly build up the car and stop when you think it's getting beyond your level of comfort and convenience.

The less stress you put in your engine the more reliable that it is going to be.
450 HP reliable? one bad tank of gas, fuel pump malfunction, clogged fuel filter and boom... Runing higher boost levels leaves very little tolerance for **** ups.
IMO:
having a CAI, upgraded SMIC, DP, MP, Catback, Fuel Pump, Injectors and a standalone ECU with your boost set at 12-14 psi is rather reliable. With a streetported engine, those mods should yield you about 300-350 RWHP.
Some people may argue that you can still up the boost and go single... But hardly anyone will say that the setup I just describe is in fact unreliable.

that or worse "I'm so stupid that I blew the hood off my car and it landed on my neighbor's cat...hood seems alright with minor welding...cat's funeral is on saturday"

So basic bolt-ons getting roughly 300 rwhp tunned is pretty reliable?
(This is not just a weekend driver. Go to take a **** at the gas station, picking up my sister, cruising around, driving everywhere like a minivan lol.)
What do you think is the max hp reliability of the rx7 is?

Fast
Reliable
Cheap
You may choose only two.
Reading all of the Rotary Obituaries on this forum lately i haven't found one yet that said- "nearly stock engine running nearly stock boost under reasonable circumstances blew up with no warning" If someone knows of a situation like this i'd love to read it.

Don't expect people to just hand you an outline to building a fast and reliable car, this is something you need to figure out on your own, meaning not everyones build is going to be the same. There is some good information in the FAQ you should probably read over, and that will get you headed in the right direction to do some more research and see what kind of mods you want to do and how comfortable you feel doing them.

Buying a high performance sports car with the intention of making it reliable is an exercise in futility. You need to buy another car if you want reliability. Don't count on this car to get you from point a to b. Buy a bike and memorize the bus schedule.

I dont see why you guys think Rx-7s cant be daily drivers. I seriously wouldnt mind driving my car everyday, in-fact i want to drive it everyday from now on. The ride on base/touring even with just springs is seriously not bad. r1 might get on some people s nerves but i really dont care driving it. My back bushing are gone, and are making **** load of noise when i hit bumps but that fixable. (anyone know what these bushings are called????) My rx7 also has low mielage (37K) and so far its major problem free but i have experienced cooland leaks, and stuff like that. You have to know about cars to keep a healthy Rx-7. That simple. As long as you take car of your car, and mod your car respectively and wisely you are set for a long time.

the best reliability for the RX7 is a better paying job.
but in alll seriousness I had a conversation with Chris at Rotary Performance here in garland Tx. They will warranty their motors but not if the car makes more than 350RWHP because that is where Chris thinks the motor becomes unpredictable. BTW... if Chris wrote an RX7 bible I would worship it, and I don't think I'm alone here. Choose a good turbo keep the boost low and the fuel in steady supply.

FLOG it = Fixing it sooner then later
Maintnance = Lots of days on the road
BIG WHP = More maintnance
did I miss anything?

so then lets review...
Fast Big Hp
Cheap correlates to.. Flogin it
Reliable Maintenance
not in that way but just for a general idea.....
if you want to make your FD reliable then by all means, i support you all the way.
heck why not just log every thing good and bad the car does and report it to us....
that way by the time you want to sell it or rebuild it we have an idea of what NOT to do....
joking aside, if you are willing to commit to this relationship with your FD then you might as well have my support
