NUB here

[SkinnyJoint]

hey guys. ok, well im going to be selling my wifes p5 and giving her mine, while i get a bike. (cbr600f4i) but the deal is i get another car as well in a few months my first thoughts are to get a 240 just because ive owned a couple before, love how they handle, could drop an sr in it and it would be quick.

but i also have a very soft spot for rx7's i really love fc's and obviously there cheaper then fd's. so heres the thing i dont really know s*** about rotary's and i hear they break down all the time and somthing about the apex seal. so obviously this scares me if i were to go look for one what would u guys expect etc.
this is just an informative thread just hit me up with all kinds of goodie info and bad info as well thanks

also do the fc turbos come stock with an lsd or just an open diff?
and everyone mentions rebuilding the engine how hard is this? are alot of special tools needed?

Well, I don't know much about rotary's, but I do know the n/a ones are very reliable. It's when you put a turbo on one, or a complex twin turbo (fd) they become a nightmare. A n/a rotary will easily turn high rpm's when built for it. I'd say do an older one if you are set on it, but I like the 240 idea myself.

seems like there are not to many rotarys on the board here can anyone reccomend a good rx7 forum?

So long as you run proper gas (91-93 octane) and perform proper maintinence, a stock Turbo II RX-7 should last a fair amount of time. Most turbo owners require a rebuild around 120,000 miles. Luckily, a rebuild is not difficult at all if you have some mechanical knowledge.

As for the naturally aspirated RX-7s, once again, if you keep up on the maintinence, the car should last a long time. NA RX-7s can pile up 200,000 to 250,000 miles and still run strong. Even better, NA RX-7s run FINE on regular gas, so there's no need to run expensive premium.

As far as the apex seal thing, when a rotary engine suffers detonation, it usually breaks an apex seal (seals at edge of each rotor). This would require an engine rebuild to remedy. You don't run into detonation too often with the NA engines, usually it's only an issue with the turbo cars. There are things you can do to prevent detonation.

For one, if you keep you car mostly stock, you shouldn't have to worry about detonation. It's when you start increasing the boost that you start running the risk of blowing an engine.

If you do mod your engine, keep in mind that proper supporting fuel mods (fuel pump, fuel injectors, fuel pressure regulator) as well as proper engine tuning (via standalone ECU or piggyback fuel controller) will help you keep your engine together.

Also, the RX7club is FULL of great info. Anything you'll ever need to know is on that forum.

ahhhhhh no no no no no first sentence is wrong. you want 87 octane turbo or not, that's what the mods at rx7club.com and the mazda dealership reccomends, the rotaries run crappier on better gas. It doesn't have detonation problems and if you run higher octane, it just wastes money and makes the engine feel "choppy".

and to answer the unanswered question, all Turbo IIs come with an LSD as do pre 88 GXLs and 1989+ GTUss (not GTU, but GTUs, the "s" is important)
