PH Fleet: Mazda RX-8

Finally released from insurance purgatory things were looking up for Dale's RX-8 ... and then



Flat out up Ex-Muhle, I knew something was wrong. Something didn’t sound quite right. The response from the twin-rotor Wankel just wasn’t snappy enough. After a brilliant day of blatting around the Eifel with my liberated-from-the-insurance-compound RX-8, fitting my new rims and awesome Michelin Supersport tyres, this was to be the first lap of the ’ring in the Rex since May. But it would be the last for this car.

Fresh new Michelins barely got scrubbed in

After cruising the short straight to Lauda Links and Bergwerk, while scanning all the gauges and dials for signs of a problem, I floored it a second time.

And the engine died.

The cries of a thousand forum experts echoed silently through the car as the mirrors filled with light blue smoke and the engine vibrated like a brick in a tumble-dryer. Somehow we were already bouncing over the grass and trying to stop. Within seconds the Mazda was parked behind a barrier and I was running down the safe side of the guardrail. No sign of oil or coolant on the floor or on the car itself. Upon returning to the car, I found the sudden stop had boiled it over.

The final indignity? Um, not pictured, thankfully
The final indignity? Um, not pictured, thankfully
After a chat with the safety team and a brief inspection of the car, it was decided to let me drive the wrong way down the hill at the end of the session. Luckily I’d gulped a whole bottle of 2-litre water recently, and still had half a bottle in the car. So the header tank was refilled, one way and another (use your imagination). Now I had a whole hour to reflect upon my options before I went back down the hill.

Firstly, remove engine, rebuild it, install it. This option could weigh in at less than a grand, but I’m not really capable of any of these things. I don’t have the time and I certainly don’t have the talent.

Second option would be to get a pro to do the above. Prices range from £1,250 for a 14-day warranty eBay motor to several thousand pounds for a guaranteed race motor from somewhere like Haywards or Rotechniks. I don’t have that much money, and I wouldn’t want to put myself in the same position again. Thinking that my motor is perfect, then watching the oil smoke appear on a bike-filled Nordschleife. No, never again.

Recovered, but going nowhere

Third option, break it, sell it, scrap it. I was emotional. This is the option that won. So when the time came, and my yellow-vested escort arrived, I cranked the motor over, safe in the knowledge I didn’t car how much additional damage I caused, and drove all the way down to the Adenau exit. The vibration through the firewall told half the story, the horrible exhaust note the other half. One chamber was dead, no doubt a rotor tip had separated. About half the power of a normal motor and massive imbalance directly related to crank speed.

Luckily for me my friend Jens has a crashed RX-8. It’s a no-expense-spared dedicated track day car, but he had an argument with barriers. Now it needs a front-end transplant. Well it’s got one.

A painful decision, but the right one.

From my initial investment of around £3,000, I have only a thousand. But using the rather nifty options drivetrain and power options of the new Pistonheads Classifieds, I think I’ve found myself another 200hp, rear-wheel drive ’ring-toy to replace the Mazda.

Now you can all say it: “I told you so.”


Car: 2004 Mazda RX-8
Run by: Dale Lomas
Bought: December 2011
Purchase price: £2.800
First month: Ignored the critics, bought a Wankel, made grand plansfor modification but secretly hoped the mod budget won’t be spent on a re-con motor...
This month: Blew the motor. Didn’t have the budget for a re-con motor, sold the whole thing as a wreck. Gutted.

So you're getting into a BMW now? Good man.

I agree with the comment above, it's only a matter of time with a rotary engine. I'd never buy one because I'd never be 100% comfortable knowing it could all go wrong at any point.

Then the engine would have been fine but the electrics would have driven him crazy.

Much as I like the RX 8 handling (I rate it very very good)it was the most unreliable car ever owned.
I think your story confirms what I always suspected. It never was developped in a proper way.
Moved on to BMW and Porsche. The engineering quality is clear from the first turn of the key....

What I do not understand is why you did not drop another engine in it. With the RX 8 it is extremely easy. The engine also ways in at half a 325i and you have lots of room to work on.

The only mod you would need to make is the separate oil tank and pump that injects oil on the wankels tips so that you are not using the engine oil to do that.

Maybe it is not to late yet.

I so wanted this to work as I have a soft spot for these cars but never had access to enough brave pills to buy one.

Sorry to hear that,

Its less common for the engine to fail so catastrophically. Failure is normally more gradual wear/loss of compression due to oil wash out by unburnt fuel from dodgy coil packs.

I was going to buy a cheap one of these recently but the horror stories put me off. Don't get me wrong, I've had cars that have cost a lot to run in the past. Most expensive was my Chimaera which I had an engine rebuild on. But that's a TVR. There's no way on earth I'd fork out a couple of grand or more rebuilding an engine on a Mazda.

I can see why you don't trust anything for an oil dump on the ring now, but unfortunately any piston engine can blow off an oil hose or seal enough to lay a slick...

Can't say I told you so because I didn't...

But, I can say- You Woos! One blow up and you flog it on, what kind of odd-metal choice was this?!
Not very PistonHeaded of you at all, hand your bo**ocks in on the way out! :-)
The right choice would be to work your arse off rebuilding it (repeatedly) after each blow up and continue trying to justify it to us all.

That and he didn't car how much damage he caused, and the option drivetrain options are good.

I do wonder sometimes.

Anyway, this isn't what you want to hear right now chap, sorry to hear you ran out of luck. But I'm sure the E36 will be a fantastic replacement, massive potential to work on these as they're so popular, and it'll look right at home at the 'Ring too!

Such a shame.

I had one of the first in the country, and never had an issue with mine (although only had it a year or so). I think the chap that bought mine still has it and hasnt had issues.

Such a nicely balanced car, and incredibly practical. Just spoilt by hideous mpg, and rotary issues. I dont think the low bonnet would take a "normal" engine, and anything lumpy would likely ruin the handling, perhaps a subaru boxer engine would work - dont know how heavy they are?

RIP the RX8 (this one and the demise of it new now).

He has a point though. A cheap as chips Clio 182 would be a fun track tool.

To fair to it, it was being hammered round the ring but there is truth behind the internet folklore, the only person I have known to own one got burnt also.

It is otherwise a decent car, a drivein/drive out V8 conversion service for a decent price would be brilliant for all the RX8's out there with knackered Rotaries.

Better to have tried and failed than not tried at all.

Still the indolence option would have saved you 2 grand so what the fk do I know? smile

Too add: I am a fan of RX8s and have been in and driven two of them now, a very good friend of mine bought one a few weeks back (very cheap) and is loving it so far.

Yes he had compression test done before buying and the car has full service history.
