FB will be more reliable, simple, cheap and IMO fun.
Rx8 is cool but will cost more in the long run.

How many tiny irradiated Japanese dicks do I have to suck to make them build this?

>>14642880
I would've assumed the opposite since the 8 is newer. Is there a certain number of miles before the engine gives out or the chassis?

>>14642894
>Is there a certain number of miles before the engine gives out or the chassis
There are too many factors that come into play here.
Mostly that people didn't know how to repair Rx8s so they neglected them and caused premature engine failure. So when you buy used you're taking a risk.

>>14642873
My rx8 has over 100k miles on the original engine and still runs strong. It's not too unreliable but you have to make sure you get one with good compression not one that's already damn near death.

8 has a better handling chassis overall, so I'd go for that personally. Also more practical.

>>14642905
>>14642918
Yeah I usually see people with rebuilt engines on their 8's because they weren't careful with their seals or ended up flooding them. And with either car, I'll end up doing a compression test when looking at them

Well the FD is faster stock if that's something you care about.

>>14642880
I don't know that much about rotaries but I'm gonna have to disagree with you just with common sense

Your really telling me that a 30+ car, with the all the seals and belts rotting away and rarer parts is going cost less to maintain and be more reliable than a car made 10 years ago?

There's a few twin turbo fd's near me, but I'm not really looking to track my car

FBs are comfy little cars, didn't have many problems with mine for the 3 years I had it (aside from winter starts because lolcarb). One note I would make though is that they're pretty noisy on the highway, wind noise would usually drown out the engine and speakers at over 70. The NB miats I have now is quieter on the highway with the top up for comparison

>>14643113
Besides the engine and rust, what other things are important to check when buying an fb?

Damn it, I'd love an rx-8, tempted to go looking soon. I was resigning myself to getting a more modest car then one drive by me as I pulled in home tonight.
I don't know much about cars though and I'm nervous about that rotary ware

>>14643311
It's 1.3L, but that's Mazda cheating.
The way they measure displacement on rotary engines is that they only measure the single largest possible "chamber" in the engine at any given time. They don't count the other "chambers" in this measurement so it's really above whatever they say; a 1.3 rotary isn't actually a 1.3.

Personally, I like the suicide doors the rx8 has, makes it seem like a rotary I would daily drive.

I really enjoy the way the FB looks, especially with louvers, but last night an FC stopped by the gas station I work at and it was a lot nicer than I imagined. My friend has an FB though, so I hope he sells it to me

>>14643504
They aren't all the same size at once. The engine wouldn't work if they were.

>>14643514
No, a stock Miata is lighter than a stock FD.
FD: 1,218–1,340 kg (depending on version)
NA: 940 kg
Fitting a rotary engine would make it even lighter still which would change both the speed and handling of the car, meaning it'd be nothing like an FD.

>>14643547
hum yeah kek didn't think of that

Damn FC's look gud

>>14643514
>>14643547
Also, it might be cheaper to get a Maira with an engine swap, FDs are still a little pricey around here

Watched a youtube of a guy doing a rebuild on an RX-8 engine. Seemed remarkably simple for a car engine, with basically just the two rotors and the crank as moving parts. Orders of magnitude simpler than a piston engine.

I wonder if buying a low-compression (but obviously not blown) RX-8 wouldn't be a good deal if you had the time to rebuild.

I'm buying an FD RX-7 and have found RHD ones in Canada are significantly cheaper than here in USA. I think the only way to legally register them here in the states though is to wait until 2017, buy a '92 FD, and register it as a historic car. Is this correct, or can any RHD FD be legally titled/registered through my state (Indiana)?

I went to my local BMV chain and they weren't very knowledgeable, and claimed I literally only needed a police officer's inspection (even a Canadian one) and correct import papers, which I assume I would receive from the dealership I purchase it from. Would it be seized at the US/CAN border? Could I drive it back through without issue?

I'm not that shitbag who made his own thread on this a few pages down, I'm reposting from an old QTDDTOT thread and figured I'd get better answers in /doritosgeneral/.

>>14643504
It's 1.3 liters. Each rotor displaces 650cc as it moves through a single combustion cycle. 650x2..

Some people argue that it should be considered 2.6l because the rotor has power cycles per revolution of the crankshaft. Those people are retarded. Two stroke engines also complete two cycles per each rev and the displacement has never been doubled to appease Honda drivers.

>>14643811
Depends on the state, but the general rule is 25 year old can be imported anywhere except Commiefornia. Now since the FD had versions sold in the US I believe you could theoretically get away with importing one that came out during the time the US was sold, but it would need to be inspected and confirmed that it's pretty much exactly the same as the US version and OK to drive on US streets.

Yeah, I'll definitely be grabbing one as soon as 2017 rolls around, I figured I'd just jump the curb and get ahead of the market when it booms next year, I'd just hate to buy it only to receive a surrender vehicle notice from the fed. gov.

FCs have legit aged way worse than FBs. By far the weakest 7 aesthetically.

>>14644370
I think they're the worst, but only because they seem like such a product of their era with their boxiness. Still think they're pretty sexy, but they don't compete with the curviness of the FB and FD.

>>14644376
Yeah, that's the exact reason they've aged so poorly. They came from an era where even great looking cars look like shit compared to both earlier and later generations of cars.

Engines are silky smooth if you like that thing. Sounds great too. Very power dense since basically a two stroke. Burns oil like a two stroke however. Oil in the gas and also injected into combustion chamber. 1 quart per 1000 miles is optimistic. People even mix oil in the tank just in case it wasn't burning enough oil. Burnt oil smells.

Rotary swapping a miata actually isn't that easy. You need a significant amount more airflow and cooling, which usually means gaudy hood vents. The weight saved is extremely minimal too, especially if the engine is turbocharged.

is there a good thread or article to read about buying an FC? I don't know if it's turbo or NA. I don't know what year it is.

I walked by the car and saw no surface rust. But that could be hidden. I also don't know the condition of the floor panels, or any of the rust on the frame.
And it's now sat so long that any oil leaks have evaporated, or stained the gravel underneath the car. But if it's sat that long, a rebuild would be mandatory.

Anon was incorrect about the FB and RX8. I maintain the shit out of my engine and the ONLY repairs I've had to make was shit I either broke myself at the track or natural wear on things like brake rotors, ignition coils, etc. All of which I've replaced with better parts and the car runs beautifully.

Also, older rotaries have a few extra flaws the Renesis took care of. Sure, it isn't as kind to turbo charge but if you know what you are doing, or willing to pay someone who does, it can still be done.

The only down side to an RX-8 is that it is about 400 lbs. heavier that it should have been. You can really feel it when a passenger gets in the car, too. I don't notice any pull issues in stock RX-7's. But I've only been in turbo charged 7's. There is a substantial power difference.

Wouldn't trade my 8 for anything, though. Still planning on getting an RX-7 FD and FC, down the road.

>>14644764
probably true

>>14642975
As an RX8 owner with bad apex seals, I can confirm. Though the late models are much better than the 04 and 05s. That said, I absolutely love my RX8 and honestly the half doors and trunk make it one of the most practical cars I've ever owned (I haven't ever owned a practical car). The 8 is a blast to drive with the traction control off on twisty roads and the 6 speed makes for nice highway cruising which I do a lot of.

Kill yourself m8

> tfw saw a RX-8 on craigslist going for 1800 that was probably only flooded but didn't want to spend money on a gamble

Would an FD with a blown motor for half price ($10k) be a gud project car? Asking hypothetically

>>14646810
What do you mean "bad" apex seals?

I assume if your apex seals break, it's like a broken piston wring: it'll destroy the rotor and housing (same as a busted ring would destroy a piston and cylinder, at the least).

>>14648909
How much will you spend on rebuilding a blown rotary?
Find out how much that will cost you before you buy it.

>>14648909
What is 'blown' exactly?

IIRC rebuild kits (all seals) are about two grand. But you'd need good rotors and housings (dunno what either cost).

>>14649026
>>14649039
Asking because I see one near my area with no compression on one rotor for $10k, when the working ones nearby go for $20k. Don't have space for one in my life right now, but maybe a few years from now.

>>14649069
If it has *no* compression you have to assume something's broken off and has been dragged around and beat the hell out of the rotor and housing, no? Or could that be a symptom if the 'spring' that presses the apex seal against the rotor wall has failed?

>>14649069
Do a little research. Find out how much a rebuild can run you in your area. Find out what tests you should do before you buy a rotary. Run a compression test. That tells you what's wrong with them quite often.
http://www.aaroncake.net/rx-7/tech1.htm
This is a good page to start with for some of the research you'll be doing. Search on the rx7club's forum for more information about FDs specifically.
As for the OP question, $10k sounds like a lot for a car that won't run. For a project that's not currently running, $10k is also probably too expensive.

If it's sitting at the dealership for 4 years, it's because he wants way too much money for it. I saw a 2001 Prelude sit at a dealership for about two years because he was trying to get literally twice what it was worth.

That is techically wrong actually
12a = 1146cc
20b = 1962cc

however 13b is 1308cc

>>14651806
That is a very distinct possibility. If he wants too much for it, I'm not buying it. It's that simple. I kinda like the looks of the FB over the FC, and I can find a running FB on Kijiji for $2k easily. If the car's been sitting for so long, and hasn't been run, then it will need a rebuild. I'm not paying the price of a running car, a rebuild kit, and either doing it myself or paying a mechanic to do it for me.
So if he knows what he has, then he knows he's not getting a two week paycheque from it.

It's the window being too small and centered to see all that is happening. The x-rotary has an oval moving inside it. The combustion happens when the oval is already tilted as that more surface area of the oval's side allows it to overcome the opposing pressure you mentioned.

FWIW, that's using Mazda's derpy method of displacement calculation. In practice the 13b is equivalent to a 2.6L 4-stroke (or a 1.3L 2-stroke), in terms of volumetric fluid displacement (i.e. in terms of how much air it "pumps" for every rotation of the crank). Lastly, each face of the rotor sweeps a volume of 654cc, so it could be argued that the actual displacement is technically 3.9L.

No, you just get bad compression and run on 1 rotor. You rebuild the engine (easy and cheaper than a new clutch) and you're good to go again.

If you're lucky, its a spring that has jammed/locked up. If you're unlucky, the seal exploded and rekt the housing. Both happen regularly.
