Backing up a statement with multiple blown motors? I don't get it. Do you get respect from blowing a motor? Just to be sure here, we're talking about a stock-ish (not counting an intake or exhaust component), not a FI Renesis, correct?


I wasn't aware your user-error argument had to do with aftermarket performance parts on the Renesis. I've just been seeing a backlash against people with stock RX8s who have followed the manual to the letter and still have had engine failures.

it appears some around here do.


I think you are missing the whole point but I am not going to try to speak for RedDevil.

im interested to find out how many 8's you think had their engine replaced and what % of cars it actually is if u actually do the research you will find that its no more than any other engine made.

you'll have that when you start getting a larger portion of the owners of the car being "general public". The RX-8 isn't selling like camry's or taurus' but they are selling to more than just the niche rotary purists. On top of that you have many people using the car as a daily driver and their only mode of transportation. It gets to them that their camaro never popped a motor but this.....thing....that they know nothing about...might.


As to the specifics - the numbers were just put out that through the end of 2006 there were better than 160,000 RX-8's produced. This forum has had several motor replacements no questioning that. Lets go with a large number....100? 500? Do you think we have 500 replaced? maybe more? 1,000? have we had 1000 engines replaced on this board? That seems like it would be extremely high judging by the number of 'my motor was replaced' threads. Even at 500 that is just a shade over 1.35% of the total membership of the forum (37,000+).

Can we consider this forum as a representative sample of RX-8 owners? Can we make that judgment call without seeing actual Mazda numbers that ~1.35% of motors are failing? My inclination is to say no as a lot of the members of this forum only found this place when they started having problems with the car and henceforth got online to search out some information. A vast majority of others out there haven't had the need to search out this community because they are going about their daily lives with no problems. Thats just one theory. Draw your own conclusion.

i think us getting new engines every 50-65,000 miles just proves we are the replacement for the FD.....

substantiate your claim.

rotten42

IMO you don't know what the f@ck you are talking about!

limepro

well experts rated the reliability of the rx-8 years 04-06 at an 8.5 out of possible 10 and by the numbers it seems that less than 1% of all the 8's sold in the US needed the engine replacement. you should know by now after being a member of 10+ forums that you only hear the bitching and not the people who have no problems.

and as for the statement i put in bold whos fault is that? its a whole new engine redesign and alot of the people buying the 8 have never owned a rotary they are used to the piston engine get in and go. so yes as you stated with poor maintenance and use they can and will break, of course theres the engines that didnt pass the recall and had to be replaced it was a very small # and others that have their problems but when someone needs multiple engine replacements whos fault do you really think it is?

ChuLooz

ok everyone, i can settle your arguements the rx8's engine is unfortunatly destructable, but this video by top gear found a car that is not, i mean, the car is amazing watch it in disbelief. there are 2 parts watch both, worth the time.

There's nothing bold about his statement. It's the absolute truth. Maintenance aside, anyone who doesn't properly rev a "Renesis" rotary on a regular bases will eventually kill the engine. These engines carbon up nearly three times as fast as the older rotary's cause of the side exhaust location doesn't allow for the carbon to properly exit from within the apex seal grooves. This is why the engine has been recalled in the first place. The engine is in fact very durable. It's just not too consumer friendly at the moment.

f'f'f'fail.

Bases on what set of circumstances?

I completely disagree. It's a proven fact that rotary's are well known for how well they handle abuse. They can go many seasons in racing without having to be rebuilt. They are also (in terms of liquid cooled engines) the ideal choice for air planes. If you ever have a cooling system failer in a airplane and loose all coolant, the rotary will continue to run providing power even while it's over heating. This is something a piston engine can not do at all.

limepro

the reason this thread is a failure

1. u came on here knowing what appears to be absolutely nothing
2. you have no facts to backup your claims
3. you just like the whiners are the reason that the engine gets a bad rep (the squeaky wheel gets the oil) if u dont understand that it means the crying people get all the attention taking away from the 100's of others that have no problem instead they pay attention to that 1 person.

and no im not calling you a cry baby u arent on here crying but u are adding fuel to the fire that the few have started what if everyday everyone that has no problems makes a new thread stating they have had no problems would it overshadow the 1 "my engine got replaced" thread? the answer is NO it wouldnt

McVicker

stupid indestructable spinning doritos

oh, btw....you should read what stokedxiv stated before. He owns 2 FDs and has been actively working on rotary vehicles for a long long time.....but in that time he retained no knowledge, and you are correct.

limepro

actually the 8 engine is totally redesigned from the ports to the compression so although he owns 2 FD's does not mean he knows jack about the engine in the 8 so yes i am correct

T-von

What you think he doesn't know that? It's really foolish of you to assume he has no knowledge of the subject. May I ask how many rotary engines you have taken apart, rebuilt and modified? Have you seen all the carbon build up in the Renesis engines primary intake runners? If your like me and have years of rotary related experience, then you will truely understand the science behind how these engines operate. It doesn't take a rocket scientist to understand what it takes to keep these engines out of the shop.

To prove my point I'm one of the very small few to have owned a 3rd gen rx7 and still have the original engine last over 100k while still proving top level performance and relaibilty. Knowledge is a ****!

limepro

i understand that but look at his statements it seems he doesnt know much even considering he owns 2 FD's he hasnt said anything to back up his claims only "what he reads on forums"

and just to back what i said up...

Red Devil

My thought of abuse in this case was end user error. I'd be more inclined to think a Supra owner can open his exhaust system, run lean and have detonation issues but straighten it out and be fine. In this same example, we're not so fortunate. Though from what I've heard, not experienced, the Renesis is much stronger in regards to this issue as compared to the 13B-T or REW.

Red Devil

LOL, should have expected that from someone who's had multiple engines.

I'm not saying Mazda, like any other car company doesn't build any bad engines. And I'm also not saying that Mazda doesn't have some of the dumbest techs out there when you have to start dealing with these engines under warranty.

A "same metal" piston engine will do this as well. Where you run into problems is when you have a motor with an iron block/aluminum head. If you don't believe me go get an old 60's buick and drain the radiator. It will run for a long.....long time w/o coolant. Which really surprises me that a rotary - with a sandwich of metals - will continue to run without warping the irons to the point of failure.

Raptor2k

I think that was sarcasm. Not 100% sure though.

And I like how some 8 owners here have no faith in their engine. 40,000 miles now which has included routine maintenance and a few redlines a day...don't see how it wouldn't go 100k+. I didn't see anything wrong with that quote from the article and Red's statement wasn't bold but rather obvious and to the point.

the rotary is exquisitely reliable, in fact it is the most used motor for military generators as well as being used in many experimental small air craft. Now the RX-8 may have had a few issues early on due to emissions but the numbers are low or the car would have been pulled. Hell my RX-7 has 250,000miles and running strong, and I have revved it till it just stopped revving and it didn't have an issue.
