Neat. That showcase engine is beautiful.

Beautiful engine. Anyone else notice that it's a 6-port?

Jon

O' my god! That is beautiful! Kinda makes me feel funny, like when we used to climb the rope in gym class...........

*wonders what this engine would look like all bling bling in his engine bay* I love it!

Now all they need to do is make it a crate motor! :)

cool looking . i cant elaborate. i might offend the post police

I will take it?

yes... i'll take... at least two.
Beautiful design, stroker and more compact... how do you argue with that?

I love this new engine. It's everything I wanted in a 15A, and then some.

I see a whole slew of "how can I put a 16X in my car" threads coming in the near future...

I don't blame them. I want one. Of course it won't bolt to our tranny like pretty much every other rotary since the 1970s... So you'll need to either custom fab an adapter or take the tranny with you as part of the conversion...

It looks like the only real way to do this one is the way the guys in japan did the renesis swap - take EVERYTHING with you and custom fab whatever you need. Not going to be easy or cheap... but would be VERY cool to have an FB that could put out more than 250hp N/A and still pass emissions.. not that I need those.

Plus you can't go wrong with an all-aluminum engine, seriously :)

Jon

its going to have the header problem all the new engines have and the exhaust tuning problem. i wish they would just put the ports back in the rotor housings instead of the side housing. all i have to say is D%# engineers

other wise id get one and not worry about it

Agreed. We, as rotorheads, already know how to change coolant and not let our engines overheat. An all aluminum engine makes sense.

That's freaking nice.

I wonder what they'll put it in? The next gen RX-8, or something more interesting.....

the next 7?

INSTANT BONER!!! I love it

Couple things to note. I don't know if it's a 4 or 6 port. I can't trll with the pictures. Also, notice right above the spark plugs, does that look like a spot for a possible 3rd spark plug? That would be cool as hell to have 3 rows of plugs like the 787B!

Or maybe it's an undrilled casting for a knock sensor. This can only mean turbo! Well, it could means SC too.

Robert pointed out the single oil hole under the pedestal. I think the incoming oil Ys apart at the dowel and half goes forward to the front bearing with the rest going down to the rear bearing. Since Mazda removed the oil banjo bolt at the lower corner on the NF01 and later engines, for more starter options, this makes sense.

I don't care what they put it in, I hope it's a 2 seater sport, but I'll buy one rip everything out put it in my 7 and have an electric put in the old shell to make use of it!
If it's a 2 seater that looks sexy like a first gen then I'll keep it as is.

On the 16X: Has anyone given thought to reshaping a 13B port to that of the 16X? Talking primary intake ports obviously, as the exhaust have been moved to the intermediate plate. Looks like an odd peak mid stroke compared to the curvalicious ports we're accustomed to. I'd love to see what they've done with the secondaries and auxiliaries. Also, what about the front plate? Seems like the rear rotor might have some added intake charge heating from the exhaust port shoved in underneath it, unless both front and rear plates have them, which would mean the center port is shared by both rotors...

On the general public as displayed in the linked thread: Amazing, going on 30 years of development, production, and improvement; having been applied to 10 or more Mazda vehicles; having proven themselves in the racing world; and people still don't know a damn bit about these engines.

"The apex seals are the weak point" my ass.

I've seen in person and read about more engines suffering coolant and oil seal issues than apex problems, and even then, most of the apex problems came from people adding an MBC and turning their boost pressure up, then cracking a seal because they ran without any fuel support.

@legokcen: If you're referring to the threaded hole above the trailing plug, I believe that would be a knock sensor hole. If you mean the blank boss above the knock sensor hole, I'm not quite sure an extra plug would work there without rendering the current trailing plug useless.

I saw this info awhile ago and love it. I think this engine will be awesome. I would love to have a 250hp first gen like jon said, that passes emissions. lol.

I just imagine all the birds that choke to death on my gas fumes and then read that this latest rotary qualifies as a "low emissions vehicle" even in cali...

I wonder with the larger stroke if this engine will rev as high as the previous renesis.

Here's hoping.

That engine would suit a rotary truck. More torque; less emissions. Mazda could bring back the B1600 and call it the B16X lol.

Fantastic! Well at least we know Mazda is truly commited to the rotary going into the future. I like the long stroke, now we'll get some good low end torque. I am also a bit concerned with the exhaust ports, but we'll see.

Larger displacement, direct fuel injection, rotor housing and side housing are now aluminum....this is truly an exciting improvement for mazda's continued dedication to the Rotary.

Sure, move the ports back if you don't want the improved power or efficiency. :rolleyes:

This engine is a pretty far cry from production, but it's exciting to see Mazda is still doing development on the rotary. That they're actually changing the dimensions and eccentricity of the rotors after 35 years is a huge development.

I can't wait to see what they slap that baby into, I'd bet the HP for a fully modded 16X turbo are unreal.

Consider what the Renesis is currently doing with a turbo. If it has good numbers, the 16X will have even better numbers.

I'd prefer peripheral exhaust ports for driving a turbo, but that means taller apex seals etc.

Damn thats a pretty motor and i thaught a 20b was badass 20b=2.1sec,
15a=1.2sec erection time achieved naturally asperated of course

Anyone else excited to hear what this beast will sound like with a header? *drool*

It's thinner, but higher and wider.

A 1.6L, sweet. Thing might crank out 300bhp stock.

Drop that in an FB, mod the hood and the tranny so that everything fits, redesign the wiring harness and you're good to go. It's all so simple. :rlaugh:

Engine nice.. car ugly

http://www.autobloggreen.com/2007/10...s-revised-rot/

i could see that car in a futuristic movie about space travel.. haha.
I still think the FD is the sexiest car that ever rolled out of Mazda's doors, and the FB most original and stylish..

I have nothing to say about the FC :(

I'd take one of the rotors from that and wear it around my neck wif a chain and be gangsta with my Mazda Bling!

The oil coolant line comes off a funky looking pedestal for the renesis 13b, so I'd say this one is similar. I guess it filters the circulated oil better?

Hmmm. . . what about a 16X in an Ariel Atom . . . ?

Buzz :-)

HEY I HAD THE IDEA FIrSt....it's true ask my friends...

Side port exhaust can blow me. They'd better not put that into a new RX-7.. I'll be pissed.

OMG! That is bad-ass! I had actually bought a shit-load of reamers off ebay searching for "16x". It is a 6-port, like the renesis, but the ports combine together in the front and rear housings. I wonder what the rotary valves look like...

wow.

holy schnit fatman!!!!

that is a beautiful engine...but that taiki car or whatever it is called looks like shit, imo. too much like a hyper car on a bad acid trip lol.

man...i wish i could get one for christmas :crying:

Wait Rotary valves?:shocking: Since when do Rotaries have valves?:Wconfused Wouldn't that imply a need for those imaginary camshafts? :P

yum, rotaryyyyyy

He's talking about the rotary valves that open/close the auxiliary ports.

The peripheral exhaust port is dead on street engines so everyone should just come to that realization. The side exhaust port is far superior for this application. Mazda Japan even wants to pursue side exhast ports in race engines. It's the americans that don't want to do this though.

Power numbers for the 16X will be somewhere around 270-280hp and 190 ft lbs of torque or so.

The aux and secondary ports do not combine internally.

do they say when production if any

A contribution from Holly:

Spot for the injector I think. Baby's gonna be DFI.

Form factor is supposed to be the same as the present Renesis which means this thing could find its way into a production -8 without too much difficulty.

Only worry I have at this point in time is that this thing has thinner coolant walls which I guess means even more craziness has to be dumped into the water pump, radiator, and the fans?

DFI for hydrogen, regular injector spots for gasoline.

I hate how everyone (including media) talks about it as if they're going to be doing direct inject for gas, when in many of the pics you can still see the stock fuel injector spots very clearly and if you spend any time looking at mazda's documentation for the H2 Rx8 that is already out you see that the DFI injectors on top are for H2.

As for the holes above the spark plugs, I have no idea. Knock sensor is as good a guess as any.

I'm not sure what you mean by "same formfactor". If it came from the factory with the ability to bolt to a current Rx8 tranny that would rock, but something tells me they might not do it that way. If they did, it would possibly bolt to our tranny as well, with a clutch/pressureplate swap... we can only theorize until the damn thing is released. IF the damn thing is ever released.

Jon

Hmm... okay I'll eat my own words.

I would normally nuke my own post at this point but this is worth just saying I'm an idiot. Ray Green's link actually says

"Mazda has developed the first Direct Injection system for a gasoline rotary engine based on its direct injection system currently used in the Hydrogen rotary engine"

... Doesn't explain why the engine in the showcase has fuel injectors in the usual location as well as injectors on top that *look* like hydrogen injectors... but Mazda's site wouldn't lie, would it?
