Well I blew my seals a while back and I took my car to what I thought was a reputable rebuilder of rotary's. I took out a loan to pay for the re-build. I just couldent go without my baby. It's now 1 1/2 years later and guess what, no comprestion on the back rotor. The place where I got it re-built said sucks to be you. Its been more than a year, the extent of their warrenty. I personally expected this engine to last a little longer than 6 months past warrenty. So now I have no car and I am still paying for the engine.

So now I come to my fellow rotar heads and pose the question, what next. I am a student so I cant afford anything. Is there anyone that can help? The dicks at the shop wont even swing a deal. Nothing like taking blame for your work when it is crap. I badly want to bring their name's into this but then I would be just as bad. Please help. Advice, anything.

RX-7 GT

why not bring thier name in? if you got screwed you have every right to be pissed. fu#kem!

if i were you i would go jspec, only $750 at nippon-motors.com and they have a 30day warranty.

we want to know who you got the engine from so we dont have to deal with ********* either

HWO

is it a turbo or non turbo, what mods?

there is a reason for blowing engines, you need to find what it is so you dont blow any more in the future

bryceschutte

N/a no mods. No reason for it to blow. he mechanic tried to tell me that some carbon or some dust ust have gotten in behind the seal. Bull ****. I dont know what kind of specialities they think they are.

RXTASY1

Is there a Better Business Beureau in Canada?
There must be some type of consumer protection agency there?
I would go to these guys and ask them to give you a break on a new rebuild. If they refuse, just tell them you will make their life miserable by going to the proper agency.

bryceschutte

I just talk to the bastards again. They wont even let me make payments on they dame thing. What the hell am I gonna do. Because they are a$$holes, I am no longer a RX-7 driver. This sucks.

PraxRX7

Specialties eh? RX-7 Specialties perhaps?

I don't know, but if the engine went for a year and a half...something must have been done right...

What kind of maintainence were you doing? What kind and how often did you check things/replace things on your car?

I am not saying it was your fault, it could be as simple as the injectros were running a bit rich causing to much carbon build up, I know for one thing that I am going to do the ATF treatment before taking my car out of storage this winter. (Take no chances, Make no mistakes)

bryceschutte

oil every 3000 relgiously! I agree that it could be my fault but at least help a guy out. I head that businesses usually want repeat buyers. I cant see my self going back there again anytime soon. Life just sucks sometimes. All you can do is hope that luck will start turnning your way. Anyone out there got some Luck that they want to share. Or maybe just some rich guy that needs to feel better about himself. Fix my car. That will make lots of people feel good. It just sucks walking. Does anyone have a really cheap car for sale then. I mean really cheap. A large bucket of rust with wheels that drives on a gallon of gas per mile would be an upgrade from my current position. I do accept donations to the my car is dead and I hate walking fund.

Dyre

There is no reason a bone stock, well mantianed NA rotory engine should blow in 6 months.

That thing should have lasted 150k-200k MILES easily/

wankelhead

what shop did you get your motor from?is it rx7-specialities?i happen to have a motor sitting in my garage from'em right now,i'll be installing it real soon........
seems like they had a pretty good track record.ah well.i guess we will see.

RX-7 GT

give us the name give us the name! we will burn down thier shop!

man it was an n/a? **** those things are supposed to be bullet proof. and no mods? **** you would have to put sand in it for it to blow....argghghh. i feel your pain.

1 1/5 years sounds like shoddy quality to me.

The engine in the '90 vert I owned was refurbished (kept the original apex seals with 30K on them and replaced all other seals, gaskets and springs) and it ran great for the next 3 years and 30k miles I owned it. It saw redline once a day and was autocrossed monthly (lots more redline those days). The motor was still fine (compression tested) when I sold it.

There's bound to be somebody near you that has a used engine for sale for less than $400, put it in yourself and buy some time. Easy as pie.

AE Turbo

How much was the total for the rebuild? I'm in need of one myself. I miss driving my FC.

Icemark

what kinda oil you been using?.. so I can stay away from it

Scott 89t2

are you running all the stock cats? they might be clogged and just puting too much stress on the engine.

Mykl

Okay, I'm sorry but there has got to be something wrong here. Even a slightly abused and not perfectly maintained n/a 13B should last longer than 1 1/2 years.

The engine in the 'vert has 40k and it's a Mazda remanued engine. The previous owner wasn't too knowledgeable about the car and I'm sure he didn't take care of it like I do, but it hasn't blown yet and it still makes great power, despite the clogged cats.

The only thing I can think of is that your OMP isn't working, causing the seals to wear down too quickly. Other than that there is no way you can destroy an n/a 13B so quickly, especially if you take care of it.

I think you just got a shitty engine from a shitty shop. I'd call the Better Business Bureau or the equivalent agency in Canada.

Good luck getting it on the road again. This sounds like a perfect opportunity for you to convert to a turbo drivetrain.

Ryde _Or_Die

Ya, my engine was rebuilt like 2 years ago & 50,000 miles ago. I haven't actually been changing fluid good enough & go over redline basically everytime I get in it & its my only car right now. My 7 runs like a champ still. You got bent over with that deal. Thats my 2.

Ryde _Or_Die

Had a question for AE Turbo...where you gettin these pics of all these fine *** females. And asians too. Dayum. Hook-it-up!

bryceschutte

So I go and pick up the car this weekend. It is sitting outside like I expected. I go to start it. Nothing. The b@stards dident even put the plugs back in or reconnect the trailing wire or any thing. I spent half an hour swearing at that specialty shop. Anyway life sucks. Anyone want a busted a$$ car?

RX-7 GT

only if its turbo

It's great to see how people can just jump up and down claiming that a motor SHOULD have lasted such and such miles, and if it didn't, then whoever built it didn't build it right.. There are plenty of other factors that go into why a motor doesn't last.. You take the word from a shop that they are going to build you a good motor, and they take your word that you are going to not abuse the motor..
There are several people on the fourms who have gotten their work dones at rx-7 specialties.. I've had 2 motors that have been rebuilt by them, an 87 T2 and an 88 10ae .. both motors are running very strong to this day.. The guys over there are great guys.. They have always been helpful with anything I've ever requested.. What it comes down to is that they will treat you as you treat them..

There are too many factors in play as to why a motor does not last.. sure you changed the oil regularly (we take your word for that), did you follow proper break in procedures? (We'll have to take your word on that again)..did you drive the car like a bat outta hell everywhere? many people have a misconception that a rotary is ment to be redlined everywhere everytime.. if you don't rev the hell outta it everytime your out that it's not going to last as long.. where the hell did that idea come from??
Did you decide one day, hmm, wonder what it would be like to drive without an airfilter? we'll assume you didn't.. but hey, there was a guy on the board who decided to delibrately drive without his wastegate hose attached just to see what would happen...

I'm sorry you ran into some tough luck, but I do know for a fact that if something was wrong with your motor because of something they did, they will fix it.. how long would a business survive if all they did was put out shoddy work? they have been around for quite a long time with a majority of their customers being repeat customers.. Nobody ever said keeping a rotary on the road would be cheap nor easy..

In the end, YOU are the only person who knows for sure if you took proper care of the motor, or might have tried a little tinkering on your own here and there which you feel should not cause a motor to blow.. If you still feel that you were wronged by them, then you're in the minority of the people who have gotten motors done by them.

Let's not name names here. That's not what I was going for. I do agree that it was probably my fault. All i'm saying is that it looks bad and a little niceness towards a guy who gave them $2500 for an engine to last 1 1/2 years wouldent hurt. I'm still paying the damn loan for the first one. I'm just a guy that ran out of luck looking for someone else rub some of theirs off on me. The guys that re-built my engine are a good bunch of guys. I know a lot of people that are very happy with them right now. I would probably even recamend others to them. Their prices are good. I have just had bad luck with them lately. Nothing personal.

"There are 5 ways to kill a rotary:

1. Detonation: Running an excessive amount of boost (air) from a turbo into the engine without the correct amount of fuel will cause detonation. Too little fuel is called running lean. A lean engine will have a hot combustion chamber. When gas goes into the chamber, it is too hot and the gas just explodes before the is rotor flush with the housing. That detonation tries to push the rotor in the opposite direction it was spinning and blows the apex seal. This is not a concern in a NA.

2. Overheating: The rotary has housings, rotors, and end plates all sandwiched together. There are passages that run coolant from one housing to the next. If the housing gets warped from overheating the water will run into the combustion chamber.

3. Lack of oil: The rotary injects a small amount of oil into the combustion chamber to keep the apex seals gliding smoothly against the housing. No oil will make the seal run dry against the housing and can break the seal or may cause overheating.

4. Conservative usage: If a rotary is driven too cautiously (too low in the rpm band or not enough throttle) there will be a carbon build up in the engine. This will continue to build up over time. When the carbon breaks free it can get wedged between the apex seal and the housing and break the seal.

5. Fatigue: It is a mechanical device that will fail after time. The turbo rotaries seem to last about 100-120K. This is a long time for a high performance engine. The NAs seem to last between 150-200k miles before they have problems, but this is variant on several factors.

Keeping your rotary alive: Oil changes every 3K miles are a must and check the oil level at regular intervals. Oil changing seems to be the most critical factor. Never overheat the engine. You can do this by making sure the cooling system (water pump/ hoses/ radiator) are in good shape.

Despite all of these warnings the engine is a very durable, powerful, and reliable engine. I have an 88 NA with 160K. I run past 7K rpms everyday and it still is strong. I have had the car for 5 years as a daily driver and run three autocross seasons with it. You can do the math, but no piston engine from 1988 would have taken that. I do change the oil every 3k miles and flush the radiator every 6 months. The rotary is a racing engine. It is very tolerant to high revs. The NA is very tolerant to high miles. However like anything racing, they are not tolerant of neglect. I hope this helps.

hhmm.....

DAMN dude that sucks

My big debate now is do i rebuild my NA now or do I pick up a 3rd gen and rebuild it slowly but do everything?

So what shop was it that screwed you???
