Approximately 39,000$ when directly converting Jp yen to American dollars, but this car looks sweet!. Twin-Turbo Rotary with updated Suspension, braking, and interior.

Is this for sale or are you trying to show it off?

yeah, what's the deal? for sale in US?

The RX-7 Type RZ is only for sale in Japan so don't get your hopes up. For more info, go here Mazda Japan RX-7 Type RZ (http://www.e.mazda.co.jp/Publicity/Public/200010/1018e.html)

that rx-7 is pretty hot

So, what's different from last year's Japanese model? I thought it looked basically the same?

Looks like a modded old model of RX-7. Boy Mazda's gone really done hill since the increased interest in the company by FORD! Let's hope GM doesn't do that to Subaru!

Homer: that is the current generation RX-7 (Gen 3). It never went out of production in Japan -- notice how the previous messages state the car is not available to the rest of the world.

As far as looking the same, AutoXr, read the article; it goes over (in detail) the updates Mazda put into the car.

Greg.

Why do the Japs keep making high powered cars for "home market only?" Its the land of perpetual traffic... hurry up and wait! http://www.i-club.com/ubb-files/rolleyes.gif

Ford's had interest in Mazda since the eighties....the Gen III RX-7 came out in the 90's.

It's still a 3rd gen RX-7 with some mild front fascia mods but basically the same body style from 99. And as to Ford's input to the RX-7, the only input they MAY have had to its demise was say, "Hmmm... OBDII modifications, LEV emissions status, and you sell how many of them a year? 500 maybe? I don't think it's a good idea." Mazda pretty much agreed with them IMHO. Just can't wait till the RX-Evolve comes out! 280HP from a NA 13B rotary! Woo hoo!

Ray

rhung, i don't think it's a 13B rotary. i mean, i could be wrong. but i know they are calling it the RENESIS (rotary genesis) or something like that. I know they chaned the intake and exhaust manifold's...so do you know if the engine block itself is the same?

It is a 13B engine with ports in the front and on the sides of the block. The current generation just has them on the front of the block.

So I guess theres not going to be a 20B n/a version. oh well, 280hp out of a 1.3L motor is pretty good for me.

It is still a 13B engine in there but it is now a 13B MSP-RE as opposed to the 13B-REW that is found in the FD3S. The difference between these engines are found in the ports as you had pointed out. The new RENESIS engine utilizes a Multi Side Port for their exhaust ports which is part of the reason for the large HP gain. That and lighter and higher compression rotors are used as well. It will still displace 1.3L, provide an estimated 280 HP at 9K RPM, have a peak torque of 170ft/lbs and a redline of 10k RPM. Obviously, this car still follows the RX-7 lineage in not being a drag machine but a true sports car for the turns etc. Other than that, Mazda is quite mum on the RENESIS engine but these are the things that are known thus far. The block internals though are changed because of the MSP design. The exhaust and intake ports are no longer where they normally but the design is still a rotary engine.

That is hands-down one of the best looking, coolest sounding cars on the planet! I LOVE the RX-7! I just wish they would bring it back here. http://www.i-club.com/ubb-files/frown.gif

http://www.i-club.com/ubb-files/eek.gif Need I say more?

Man, I'd really like to drive one of those.

Me too.

Also would like to own one... but only if those stories of rotary engines being timebombs are exaggerated and/or untrue.
Anyone here own a RX-7? How robust are those rotaries?

The early rotary engines weren't so good; there was a problem with the engine seals which is a key aspect of this type of motor. When the engine seals go, you're pretty much screwed. The newer rotary engines (ie. the 13B) use better seal technology, and are pretty good. I've heard that rebuilds are required around 100,000 Mi though (but that they will then go another 100,000 Mi).

The RX-7s you can get in the States had rather poor gas mileage. Sometimes the turbochargers went. Get as late a model car as possible, since there were a number of TSBs and recalls on the early 3rd Gen RX-7.

Great car. Almost got one with under 20K Mi on it last year.

There are a couple guys on the board with one. RotrPwr, for example...

Greg.

I've seen a bunch of ads online where people were selling RX-7s with "1 mile" on it. Turns out all of them had 1 mile a new engine, and not on the whole car.
Are engine replacements for RX-7s a common thing?

Hi guys,
I love hearing all the mythical legends that people hear of rotary motors. Yes i do currently own a 93 Competition Yellow Mica. Ive had 3 3rd Gens also. One single turbo which i sold and one Montego blue which was stock, which i recently sold. Rotary motors are in no way timebombs. But like someone had pointed out, the earlier RX7's had very tempermental motors, especially the ones that were carburated. The earlier ones had very poor coolant seal designs, and very poor seal materials. The old 12A rotary motor had the most reliable apex seals though. The newer 13-REW found in 3rd Gens have a smaller apex seal than the 12A. The poor gas mileage is very characteristic of a rotary motor since the motor uses the evaporation of unburnt gas to help cool the inside of the combustion chamber. The rotors actually rub against the rotor housings at times. We all know friction is heat. Heat is what kills a rotary motor, not mileage. Ive seen rotary motors achieve over 200kmi on a stock motor! Its all preventative maintenance. The key to having a rotary motor survive for a very very long time is 1)Keep the engine as cool as possible(upgraded radiator if need be)
2)Keep an eye on/change the oil freq. Some People dont understand that rotary motors have to burn oil. The oil helps to keep the apex seals in good shape. Low oil or old oil=bad apex seals in time.
Hope this helps.

Darril

if you ever have anymore questions feel free to ask.

Also, most people don't bother doing maintenance on the RX-7 thinking that any engine can last 10000 mi before a oil change. That, and most of the engines blow because the owners will put in free flowing exhausts, intakes and FCD but do nothing about increasing the fuel. Thus, boost is increased but fuel remains the same so the mixture goes lean, and... Boom! Detonation.

As for mileage, I own a FC (2nd gen) NA RX-7 which is my daily driver. I average 20-24 mpg in the summer and lower in the winter. The thing is, the RX-7 is a sports car. Who drives a sports car to get good mileage? True, a rotary will use more gas due to cooling and very poor flow through the manifolds (Intake manifold has a 90 deg bend in the runners) but there aren't many sports cars that can get gobs of HP and still have high gas mileage. Either way, I would get this in a heartbeat as I love the concept of the rotary engine.

Ray

Ray,
Right on. Lots of the reports of rotary being unreliable are from poorly trained technicians working at Mazda USA and from people who go nutz with adding boost and dont add the fuel to go with it. On any turbo car that will make it go boom. Often the technicians that were not trained properly would misdignose a loose vacume tube as a blown motor or turbo, you cant really blame them but the people who didnt train them. I have had 3 1st generation Rx-7's and one of them had over 200,000 miles on it when i got it and the motor hadnt been rebuilt. It ran good till the injectors caught on fire (it was a special edition 1st gen known as a GSL-SE, the only 1st gen to come with a fuel injected 13b motor). Although its almost a rule that a turbo rotary will need a rebuild around 100,000 miles. I love the 3rd gen 7 (espicaly the 93 CYM R1 like yours Darril, its my favrot)
