Newbie, want an RX-8!

Post by ninjarrr » Mon Jan 22, 2018 12:32 pm

Hi all,

Just joined as I've been toying with the idea of buying an RX-8 for a few months now and have finally seriously started to look.

I've read a few buyers guides etc. and just signed up to reply to one of hte "FOr Sale" posts here but looks like I can't do that until I make more posts so just in here getting my post count up :)

Any buying tips (check/budget for for engine rebuild, check compression etc.) would be welcome!

Oh and I should add, the 350Z is also tempting but currently being beaten by the RX-8 which have much lower resale prices (more fun per £).

Welcome!

Have a mooche around in the FAQ area for all you will need to know and more, generally paying as much for an 8 is the best advice I can give if you want to do less repairs or initial maintenance, look at the history, ask what has been changed recently etc. A recent compression readout from who you're buying from would be good but having one done yourself is better if you're willing to pay the money.

I'd PM the person on the selling advert on here (I think you can PM with small post amounts) to ask about the car.

350z's hold their value very well but they are not a specialist car like the RX8 in my opinion, they're just a nice sports coupe with a regular V6 in it :)

Hi and :welcome: ninjarrr. :D As a guest you have 'read only' access to the Buying & Selling section (which is where all the advertised cars are for sale of course), but you can send PMs to anybody whose car is advertised there if you are interested or want to ask them questions.

As for buying tips, what to look out for etc, your best starting point is to have a read through the Buyers Guide viewtopic.php?f=25&t=24047 and if you add your location in your profile we may have local meets we can point you towards where you can come to ask questions in person and nose around some members' cars if you want.

Happy hunting. :thumleft:

I fully sorted RX8 could cost more than the 350z.

Either fully sorted before you buy it or you buy the car and then have to replace the coils/HTs/plugs, possibly the cat, and tyres, and pads, and hopefully the engine is sound.

Just make sure that you've budgeted for these items.
MRP is a good source for parts, much cheaper than your dealer, and OC members even get a discount, but the costs still come as a surprise to the uninitiated.

Thanks for the warm welcome all.

warpc0il, I'm seeing 2007-9 models on sale for £1,500-2,500 with a recent engine rebuild (<10k miles) or good compression test results and upgraded coils. Setting aside another £500 for repairs, I'm counting on getting a "mechanically good for 3+ years" car for £2-3k all in. Is that unrealistic?

If the cars you are seeing have had new coils (genuine - ie from a known source like MRP or one of the listed traders on the forum - Mazda or upgrade D585 coils etc), which is likely if a rebuild was recent and there should be receipts as evidence where they came from along with the evidence of the rebuild, then your expectations are not unrealistic. I think warpcOil was more emphasising the need to inspect the car and it's records, as you should with any car of course, so as not to be caught out with those unexpected expenses not long afterwards.

What do you think of relatively low mileage 2008/9 cars (40k-60k miles) with a full dealer/specialist service history? If the compression test results are above 7.0 and similar across chambers and the plugs and coils are fine (though not upgraded) would you buy?

These kind of cars are around £2.5k-3k so I wouldn't have much of a repair budget remaining.

Or would you rather buy a similar mileage spares/repairs car for under £500 and get the engine work done myself?

Why specifically 2008/9?

There are very good RX8s from 2004 onwards.

I'd be buying on condition rather than a specific year, but at the end of the day it's your money not mine, so go for what makes you happy.

I don't want to put you off, the RX is a great car but from my personal experience, even if you do everything right things can still go wrong.

I bought my low mileage from a 'reputable' specialist dealer and paid top dollar.

Within the first year...
New decat fitted
Replaced powered steering unit.
Brake lines blew but fortunately I was able to use the back of a friend's car to stop.
Nearside oil line leaked despite having had the mazda recall/refit.
Rust developed in all four corners of the bodywork, i had rear quarters and sill cut out, rewelded and resprayed, roof resprayed. Waiting to get outstanding issues sorted before i get the front wings & boot replaced, the get the bonnet resprayed.

In the two plus years I've had the car most of my upgrade plans have been put on hold as I've gradually worked through most of the car just to keep it mechanically sound.

The only thing that hasnt been a problem is the engine!

Basically its Rust! Rust is the big killer, have a good look around for a car with minimal rust on the underside.

Most people seem to think that an engine with 6.0+ bar evenly across all rotor faces is acceptable. Mine were high 7s for reference.

So recap, if I were to do this again I'd look for a recent compression test with 6.0+ bar and minimal rust on the underside.

And check frequency of oil changes, plug and coil changes!

.. and a late 08/58 or a 2009 will be an R3 (possibly a 40th edition 08) and you won't get a decent one of those below £5k so £1500-£2500 is unrealistic ;)

As above, it all depends on the condition of the individual car (Rusty Nightspring's example above shows rust can be a serious issue, so I'd be looking for signs of that just as I would with any other car). In theory yes I would buy that low mileage car (I'd be happier with a specialist history than a main dealer one with a couple of exceptions on the main dealer and I'd like to know which specialist serviced it). The coils don't need to be upgraded, if they are definitely genuine Mazda and haven't been on the car for about 30k miles yet they'll be absolutely fine, I would want to check those details or budget to replace them if I can't be sure.

If you can find a good condition/rust free spares or repairs car for £500 or less, again I would seriously consider that and get the rebuild done (all in with the car, rebuild plus additional parts and bits that may also need doing I'd expect to have paid out up to about £4k in total doing it that way).

I would say get the best condition bodywork car you can.
All the other bits can be added ,changed over time. You don't really want to be spending your cash on constantly patching up a rust bucket.
Be warned though it is very easy to get the bug and want to upgrade everything..!

Thanks all. Having owned an old MX5 before, I know just how lazy Mazda were with rust proofing so will keep an eye on that too.

@Rotary Potato (nice name!) - 2008/9 because they're the newest cars in budget. I heard there were various issues with the very early models like leaky boots. Though you are right, condition is more important than age/mileage.

So the main things on the checklist are:
* Rust-free / minimal rust
* Recent rebuild or compression in high 6s and above
* Service history for annual plug and coil changes (every 30k miles)
* Gut feel on whether the owner has been diligent with oil changes
* Service history from a reputable independent

I'd say for piece of mind get a good 06 or greater as these have better rust prevention that earlier models.

Or get a decent condition older one and get down to your garage for some serious undercoat/waxoyl/POR15.

Coils won't be shown in a service history (unless the owner asked for them to be changed), Mazda didn't have them as a service item. :roll: Receipts are the best evidence of them having been replaced, but again look to see where they came from - there are a lot of cheap copies and pattern part coils about and they would need replacing pronto.

Also, even if the coils have been replaced with Mazda ones, check how much mileage has been done since. They only last around 25k miles.

If they have been replaced with 585s you should be golden.

I'm still out here on the hunt!

Hoping to do a few viewings this week.

One of the cars has had its cat replaced too - I understand this is likely to have been an issue with coils/spark resulting in too much unburnt fuel causing problems for the old cat and that this will affect the engine seals too. The engine has been reconditioned - are there any other components that could be damaged as a result of this?

And what kind of things would you still look out for (other than rust, consumables) on a car that has been freshly rebuilt by a rotary specialist?

One of them told me they don't do compression tests for rebuilt engines as they wouldn't get decent readings until it's done 2k and broken in and even then it needs 6k+ miles for meaningful test results...

A couple of points ...

1.Cats can collapse for that reason ... but RX8s are hard on cats anyway, so I would keep an open mind on that one.

2. It would entirely depend on the specialist. To hear that some specialists had worked on a car would be enough for me to reject it outright. Other specialists would fill me with confidence that it was a good car. Not all specialists are created equal.

3. They are right. My fully rebuilt bridgeport has done about 2k miles since the rebuild ... compression is still in the 5s. I really hope that goes up over time! :lol:

:whathesaid: First thing I'd look for would be which rotary specialist did the rebuild. The good ones would also have had an eye on the rest of the car for other issues I'd think and would have advised the customer if the rebuild would be a waste of time if the rest of the car was about to fall apart.

I understand that is true about freshly rebuilt engines not always having the best compression numbers immediately and that it improves during/after the run in period when everything has had time to properly bed in and settle down etc.

hi there for me the biggest issue going forward would be rust as pretty much everything else is bolt on and easily replaced.all the maintenance and keeping the vehicle running advice and parts are to be found on here but no one can unbolt rust. as for the future the huge quantities of breaker cars and spare parts means that this car will shortly become even rarer than it is now ,and who knows in maybe 5 or 10 yrs a well kept rust free one might be worth a packet ,i will use ford capri as an example,check them out .as said already by others do use the club to check on specialists .if you keep digging you will find the same names cropping up and for the right reasons .lastly be prepared to travel as specialists are not as thick on the ground as dealerships or car sales forecourts.hope this helps. rob

Thanks very much goodeggbob, Shagrington and rotarypotato - I'm really looking forward to some test drives now!

This forum is invaluable for advice and comments on specialists. Through a lot of searching my list of trusted specialists now includes: Apex, Warren Court, LC Rotary.

If you think any of those 3 shouldn't be on my trusted list please let me know here or send a private message.

I'm down South so I've not really considered any specialists north of Birmingham.

Depending where in the south you are and what side of the river!

If North of the river then Essex Rotary. If North of the Wash try Boston Rotary.
