well why dont you enlighten us with your knowledge of the rotary motor then. i have not owned one so i dont know. i am only going on all of the things that i have read about the car which is a pretty good amount. i am also going by the fact that a very high percentage of the last body style rx-7's have had to have their engines replaced. dont just come on and say that there are false statements. if you know some of these are false, or maybe i have had some bad information please go ahead and tell me. i just want to learn more about the car.

Rotary Fun Fact!

You can blow up a rotary by pulling one vacuum line!

[Rotary7]

@ Shin180sx..
Which vacume line is it?Hurry and tell me...durr durr All I have is 1 vacume line { for the brake booster}

Ok about Rotarys...
12A=1.1 /2 rotor
13B=1.3 /2 rotor
20B=2.3 /3 rotor

You can greatly inprove your HP by porting it..
Street port..
Bridge port
Perifical port
J port

You can either do 2 things on EFI engines...either go to a carb set up..or bigger injectors..since it only has 2..primary/secondaries..
"Lack"of fuel will burn out your apex seal..
To much fuel will not...

On 3rd gens ...most of them are damaged cause of owner missuse or lack of maintence..All turbos need to be rebiult about 60k miles..cause of bearing wear..Rotary engines just dont go bad...

Yes you can brake apex seals..or damage or shoot a rotor...But most of the time in rebuilding a rotory you just change seals..You use the same rotors..theres not much to change on the inside of a rotary...

Im not sure what you guys want to know..If you have a question just post it ..Im not gonan sit here and give you a history lesson on rotarys

don't forget about the 93 that would catch on fire I did a lot of reseach into 3rd gen rx7s, because I was looking at getting one. From the more people I talked to, and the more boards I read (actual rotary forums), they tend to have probs *if* the previous owner did not take proper care of the vechicle. They are beautiful cars, but you need to know that they are problem prone.

[Rotary7]

See what you are saying?

*if* the previous owner did not take proper care of the vechicle...

That was dumb...that goes with any cars..You think a 100k$ is any good if the previous owner didnt take care of it and drove it?

I never heard of all 93 catch on fire..if it was a known problem then it would of been recalled long ago for the fix..Im part of 2 diffrent RX7 forums..and no one at all has metioned all these 93s catching on fire..

So this scared you off and you bought a Ford Tempo instead?

[Rotary7]

BTW FD twin Turbo set up wasnt to good..they should of stayed with a single turbo...THAT was one of thier problem

[drag0n]

ok, since you won't take my word:

There were 3 recalls on these cars: brakes (vacuum hose modification), new (high temp) fuel lines, and cooling system (pressure cap and fan control module). Most cars have had the cooling system recall done (the recall was issued early on). However, I have seen quite a few cars that had not had the two remaining recalls done. Mazda dealerships are supposed to place a sticker on the driver's side door jamb when they perform a recall... but the cars are often missing the sticker for various reasons (fell off, never applied, etc.). '94 and '95 models may not be subject to all of the recalls. The best thing to do is to call Mazda Customer Relations (1-800-222-5500) with the VIN number and ask which recalls the car requires and if they have been performed. You can also find out what, if any, warranty work has been done on the car. If any recall has not been performed, a Mazda dealership should perform them free of charge.

here are some sites you might wanna check out:

check out those sites, then get back to me


oh, and here is one more:

the reason they recalled the fuel lines was because they would burst, and start a fire

[Rotary7]

Lies all lies!
Cant be..lol
OOh well diff cars diff problems..

93 First year of twin turbo..and FD ..so they had to work out thier bugs..I will still take one over a Honda anyday...

[drag0n]

hondas, the torquless wonders....

[Road Rage]

ive heard bad things from people who have never owned one and good things from people who have, but the same goes for every car, if you take care of it then it will last and if you dont then you wont have too reliable of a car

[Rotary7]

Well piston engines are everywhere....
Not to many people know how to work on a Rotary engine..BUT there are a couple of Rotary shops that do know how to work on them..
Sh1t even most of the techs at the Mazda dealerships dont even know hot to work on them..they better learn fast..cause the RX8 will be here...

OK, first thing's first:

3rd gen reliability and 1st and 2nd gen reliability are two completely different things.

1st and 2nd gens, make sure it has oil and water, that's about it. My 91 had a rebuild at 140k miles, it has since gone 40k more problem free miles. I've heard of many people getting upwards of 200k miles on original engines in 1st gens and 2nd gens.

Mazda went overboard on the 3rd gens. Owners didn't understand the complexity of hte car, neglected to perform routine maintenance, engine lets go at 60k, 80k miles. Definitely not a reliability issue, it's the DPO issue (dumb or dreaded previous owner).

If buying a 3rd gen, you need to perform some reliability mods on the car first - get a boost gauge, eliminate the crappy plastic AST, get a DP to replace the mid cats. The DP actually helps to cool (however so slightly) the engine bay as rotary exhaust is pretty darned hot, and the precats just slow the flow.

Jeesh, my 2nd post on this board is having to disspell the rotary's horrible reputation - all because of some dumb previous owners. FWIW, the rotary has an excellent reputation as being extremely reliabile in endurance racing.

lol jeez.....this thread won't die I already got a car...but I appreaciate all you guys' willingness(sp?) to help!
