heya everyone really need some help! just over 4000 miles ago i had my engine rebuilt by reworxs and since then hasnt put a foot wrong! until.....
i was pulling away from the traffic lights, not hard as i had only been driving 10-15 mins when i heard a horrible metal screeching sound and straight away the boost gauge was fluctuating and idle was rough as .......s. there was no power when i tried to put my foot down so pulled into the petrol station and switched the car off straight away!
5 mins later i turned it back on to see if there was any change but still it sounded like a god damn scooby :(
so long story short, got towed home parked in the garage and left it for the night!
next day tried starting and wouldnt even turn on! it sounds like its a dead battery almost when trying to start. if it was a blown engine would it sound like this?
another wierd thing is that all the interior lights and stereo works apart from the power fc commander and my Trust Profec E-01 Boost controller dosnt work? could it be a problem with the ecu?
any help would be greatly appriciated :)
damn if that blown thats like the 3rd 7 to go this month, have you tried jumping it with a battery pack also you sure you did not boot the car as the same thing happend to me last year and i blew a tip, put a vid up if you get it running.
What was your oil level?
Did the car overheat?
Does it sound like a tractor?
Check the map sensor hasn\'t come off
If it has im sure its still under warranty? What work was done when it was rebuilt? New seals etc?
Quote from: hazza_ek;709863Blown Engine after 4000 miles? cant be can it? :(
Yes.
Yours has done well. Mine lasted 1100 miles before it broke a tip
Oil was changed 40miles ago lol didn\'t overheat mate just sounded like a scooby. Map sensor??? How do I check that? Lol yer the engine had a complete overhaul. Rear rotor and housing, tips etc
Luckily if it is a rebuild it\'s still in warranty!
Would love to hear of a warranty being honoured. hope you get it sorted lads
If she sounds like a tractor (proper diesel-esque grumbly noise instead of nice growl), boost gauge is all over the shop and you have no power then im afraid it sounds like you\'ve thrown a tip.
The MAP (manifold absolute pressure) sensor is a wee black box on the firewall behind the upper inlet manifold. it says Denso on it and has a vacuum line running to the manifold. If the hose is loose or split then she\'ll run like a bag of spanners. might be worth a look.
My car would still start with 2 blown tips on the rear rotor, and one on the front - with a hoof of the throttle though!
It will sound rough but the car will shake at idle as well - mine was driveable under boost - but could not get more than 0.5 bar. Pulling away from a standstill was interesting.
I had no issues at all with the electrics.
I really hope that this is not another rebuild - mine is in bits at the moment, and when it\'s back together it had better last more than 4,000 miles.
I\'d really like to know why re-built engines are failing so quickly - if it\'s oil starvation or fueling issues - or a poorly specced car being thrashed at high boost I can understand it, but a well maintained car pulling away from a junction sedately - this has got to be a build issue, or is it really the case that a tuned rotary is THAT unreliable?:Hammer
depends how long since the rebuild for a warranty claim.

I think ancillaries play a big part. These cars are now 15 years old so the ancillaries will probably need changing. It is best to check as these can cause an engine to go.
The map is VITALLY important to the life of the car and simple things like checking oil levels, checking hoses aren\'t split etc will go a long way.
And to answer your question... no rotarys are not unreliable.
10 months ago the rebuild was done. I maintain the car regardless of cost oil water spark plugs every 2000-3000 miles. Very rarely drive the car "hard". Obviously put my foot down onto motorway but nothing too stupid. .... take that it\'s gone again though.
Not sure y it isnt even starting though? Get it down to reworxs and I\'m sure they\'ll figure out wats gone wrong. Can\'t see it being a build issue as they r top blokes down there!
You might have flooded the engine if you have kept trying to restart it, what condition are the cooling system etc like, also have to changed the HT leads, might find that one lead might have gone and just meant that the engine is only getting a spark to a single rotor etc
Bad news, take it back or get it back to Re-Worx and let them have a look I wouldn\'t do anything till they have seen it.

I disagree, most rotary owners KNOW rotaries are unreliable. Apart from the naive and lucky few ones.
Rotary owners preach how reliable they are...then they throw a tip on thier 1st 2nd and 3rd engine. then they just keep quiet about the subject (like i did). I used to get from people " heard these things are unreliable " i used to swear blind that they were not.
Now i say to people yes they are unreliable but alot of fun when they work.
My engine ive just built will make 500 fwhp and im expecting it to last a few track days and thats it. if i get more great if (if it doesnt it hasnt cost alot). i am not going to pay 4k for an engine that may last only a few k. i can do 4 builds for that and it just makes sense (now ive done it once, last week).
Going by the "old ancillaries logic" people who want a reliable rotary need to spend 4k on a rebuild then another 4k + on brand new mazda ancilliaries?. so is a reliable engine going to cost 8 grand?? then is that going to pop early anyway due to it running high hp?
for 4k you can get a good car
for 8k you can get one hell of a better car
i couldnt justify putting a 4k plus engine in my shell. my fd is 18 years old and is really starting to look and feel it too. It just doesnt make economic sense anymore.
As far as the MAP goes. it means nothing if an ancil is busted or u get boost spike or your rotors are out of tolerace or any other part of your engine. Why do people keep going on about maps buy a map, map again.
sort your afrs out use a standard timing map and thats it. get an afr gauge mount it on your tacho and get piece of mind. wait for your engine to go pop cos the spark plug end broke or something else.
i love you all. good night

Hi I dont know the meaning of unreliable rotary!!!Any engine is unreliable when it is not tuned properly so please I would not accept that..I know you might think that "wait Mir when you blow your engine"..I have blown four rotary engines within a short span of 4 to 5 months and realised that it was not the fault of the engien it was the bloody fault of the tuners and mine...it was tuner\'s fault because they never bothered about my car just because i NEVER gave them a job so they ....ed my car (wont disclose the name of that well tuner who conned me big time!!) and secondly I did not do justice with the car either...I think once the car is build right!!!it takes time for them to go!!! Piston engine goes as well if it is not properly build so piston is no different to rotary!!!
I am running 3 rotor engine in London area and I can tell you!!I enjoy every moment I drive that car..sorry but I would not like to hear anything said against rotary :mmmm!!!
Are you saying they didnt give a .... about your car cos they didnt build the engine and just tuned it???

I agree ancilliaries play a big part - everything was in perfect working order on my old engine,mapped by a very well know specialist.....running good compression....first track outing... BANG.
I am going to have another go - and the new engine has been built with PTS apex seals, ported etc. and no expense spared. If this one goes shortly after it is in the car I\'ll call it quits with Rotaries and look at a different car, or a different engine.

i had your exact idea. "One more go, just one more go" Its addictive isnt it.
We\'ll see - I am fully prepared to have an engine last 20,000 miles running a bar and 450 flywheel power. if it goes pop after 5,000 then I\'ll look at putting in a V8 - or I\'ll break the car for parts.:eek:

I dont think it matters why. if they keep blowing up. which they do they are unreliable. when your 3 rotor blows for any reason and youve only done 10k miles in it or whatever you get out of it. You could say it was reliable until it blew up for x reason.
Its still a bust engine and an undriveable car no matter if its reliable or not. see what im getting at.
theres an waful alot of very reliable rx7s on axle stands all accross the land as we speak.
id like to think 99% of people on here have a map thats been done by an experienced tuner who uses tried and tested timing maps per application then its just a case of afrs largely. so its not mapping. engines still go pop left right and centre cos they are inherently susceptible to go pop (for whatever reason(s) so just accept it. I do. Or dont accept it. its up to you.
wooooowwwooo calm down people i only wanted to kno if my engine had gone pop haha and rotary engines are unreliable....fact! its probably the craziest and stupidest engine out there but when they work theres nothing better. they just sound epic. look after them right and "touch wood" they should look after you.
on a stock rotary i havnt heard of one lasting up to 80,000 yet when you can pick up a honda or audi with 150,000 still as strong as ever (e.g my old civic lol)
the reason everyone who owns a rotary says they are reliable is probably cause there engine hasnt gone bang...................yet :)

Depends on a) where you are - there are stories of many FDs running well over 100k in the US
b) which RX7 you have, FB/SA22s will run well into the 130k+ many far more becuase they are not stressed engines, my FC TII as stock managed over 100k before needing a rebuild
c) how heavily modified it is, if as stock an FD engine will go for say 60-70k running at 255bhp then if you ask the same engine to run 500bhp, you can\'t expect reliability. The same can be said for Skylines, Supras, et al.
I take it all back.
could be your plugs mate i had this happen to me was out drivin car fully warmed up no messin just potterin about and boost cut in half loppy idle car was backfire and car was shakin quite bad switched it off and car wouldnt start after it changed the plugs fired straight up no bother hope this helps
If you\'re concerned, why not speak to your engine builder to find out what it may be or get it looked at?
It could be a whole host of things.

Dr..
Our disagreement is understandable..but please atleast dont curse me:Giggle..dont wish for my car to blow on the figure of 10k or so...:eek:....Secondly yes there are rotaries on the axle stand but they (rotaries) are no different to pistons (except 1.3 rotary can beat 2.6 piston:spankbut 1.3 piston can not beat 1.3 rotary) which are also in aboundance on the axel stands all across the land as we speak:Giggle
just curious, rx7 is 1.3 engine, how many 1.3 piston engines can run 300bhp+ and last any lenth of time?. jon.
Quote from: jon103a;711957just curious, rx7 is 1.3 engine, how many 1.3 piston engines can run 300bhp+ and last any lenth of time?. jon.
How many pure sports cars from the factory have 1.3 engines and are insurance group 20 with 911 turbo MPG? None but the RX.
You really cant compare a 1.3 piston with a 1.3 rotary in displacement/performance terms. but yes a 1.3 engine running between 300 hp and 900 hp isnt going to last long and yes the higher the power the less it will last. Fact is these angines are blowing up left right and centre. im prepared for it and im not going to be bitter about it anymore:guinnesslets get ....faced

i take it all back. :Thumbsup! please forgive my moment of insanity :yes
im not bitter about mine popping, water hose split - it cooked, could happen to any car, i am bitter i got it back in march but still havent properly got it on the road- no mot still and done about 75 miles in total, my fault not the cars....

Good one. I hope you have better luck with your next set up.
So hazza ek, have you got any further with this problem as its been a while?
It\'s at reworxs now. Got it down there this morning. Gonna b monday till the compression test so will update wen I find out
