Will it be possible to swap a 16X into my 2006 RX-8 (when it comes out of course)? I always assumed it would, so I've been saving and I'm up to 5k or so but lately I have been hearing around that it won't work. If it won't I really want to know now, than money can be put to excellent use somewhere else.

Yes, I searched...

Your asking a question about an engine that only exists in Mazda test cars. How can we know without having a few of them on the road? Also how much do you think Mazda is going to charge you for a new 16x?? Its not like there are any in junkyards.

Falken

I am asking the question specifically because in another thread someone specifically stated that 16Xs will not be swappable into current RX-8s.

I expect that I will be pumping out 10k for it. I am willing to do that, I've always viewed it as a not-so-thirsty version of the 20B swap. Wrong??

How did you always view it as that? News about it has only recently surfaced. And it's not going to be like a 20b either.

Odds are that by the time the 16X ever hits the streets (assuming it ever does), you'll long be past your current car and on to the next or the one after that.

Now to answer the question, from what it looks like in the pictures the transmission bell housing bolt pattern is the same which would mean that it will in fact bolt up to the current transmission (or any back to 1974!). You would probably have to fabricate motor mounts but that's not hard. The big issue will be the fuel and ecu upgrades as you'll most certainly need to use the ecu and fuel pump from the new engine. Since it is getting direct injection, the stock ecu won't be able to control it. Neither will the current fuel system.

The short of it is that any engine is swappable into any car with enough time and money. If these 2 things aren't going to be an issue for you then you'll only have to wait for the last problem and that is the wait to see when and if it ever comes out. Then you'll have to find one.

Mathematically, like I view everything else.

The 20B-REW out of the 90's cosmo produces 300HP and 300 pound-feet of torque. It also gets 10MPG and I would be hard pressed to find one with low miles. Those run around $5,000 online with installation running $2-5K from what I've heard.

The 16X Engine is predicted to produce similar 280-300HP, likely similar torque. The engine is lighter and smaller so it will not displace handling like the heavy 20B would. They are all brand new seeing as how none really exist right now, and will get more than double the mileage of the 20B. The engine should run 7-10K and the install can't be that outrageously much more than that of the 20B.

Thus we arrive at my view that the 16X is basically a solved 20B and a solved 13B. And thus we arrive at my decision that if possible I will pay for the swap the day it's available.

save your money for something else.

Which Cosmo are you talking about from the 90s? I only know about the one from the 60s.

Falken

I'm fairly sure they were made up through 1995. Anyway this is the engine I was referring to:

That is the triple rotor, 300HP engine from the 90s cosmo. It produces similar power numbers to the projected 16X ones but falls far short of it in all other aspects.

fahrfegneugen

They were under the RX badge in the U.S. though. You had the RX-7 till about '95. Maybe in another country it was the Cosmo though? IDK

Falken

Sure. My point is that is the engine I was comparing the 16X to.

Can anyone confirm the claim I have seen floating around that "16X engines will not be swappable into current RX-8s"??

RX-LR-8

No nobody can confirm that. It seems like it will be possible as Rotarygod has said.
If u wanted u could put any engine into any car its all about money.
Here just put this one in your 8 http://www.rotarygod.com/index.php?t...TARY_HISTORY_1 its a 5cc .30 cu in Wankel it makes 1.27 hp and its a rotary that doesnt use to much fuel hehe

wait for the warp drive flux generator instead ...

fahrfegneugen

That will be a while, they are still having issues sorting out the flux capacitors.

rotarygod.com? Imposter!!!!!!!

hello. he means one of these



Mazda Cosmo

Falken

Thanks for the replies.

All I really wanted to know was if anyone at mazda had explicitly stated that the 16Xs would not be swappable into RX-8s, like I had heard had happened.

Thank you!!

dillsrotary

do you realize the weirdest of you question? The engine practically doesn't exist yet, and won't for quite a long time. Anything is swappable with time and money, but even if you had that you'd have to wait at least 5-7 years till the engine see's production.

zoom44

no no one has said explicitly. as stated above by RG there are only a couple thing sthat would slow you down. PCM Mounts and tranny. you may have to swap the tranny. you'll definitely not be able to use the RX-8s PCM and you will need different mounts.

Falken

Really? I thought we would be seeing it around 2010-ish, in the RX-8s replacement.

fahrfegneugen

Thanks.

premature threadding??

I heard that the 16x won't fit, but good news: the 24x will!

Don't worry. I'll get you your desired engine as soon as it's available. I can supply the 09 engines presently for those who want to spend that kind of dough.
You're looking at $6500 to $7000 on that. I don't think the 1.6l will be much more.

Paul.

LionZoo

Then again for the money you spend on the swap and the money that will be required to troubleshoot the car, you're probably close to being able to buy the car that the 16X comes in anyway. Throw in the RX-8 as trade-in and you're probably there.

daisuke

the new 09 engines aren't a direct swap either are they?
