Having just the right amount of technical details conveyed in a manner that most people can understand is essential. Of course the WFO throttle blasts are understood by all. Nobody does it better than FullBoost🇦🇺🏁

[@rafalsanbra9758]

In the island of Puerto Rico so many rotary vehicles are seen throughout. So many car enthusiasts have a devotion for these rotary engine power marvels 🇵🇷 😊.

[@roysampson182]

The ZF autos are an incredible transmission. Cool to see the mix of old and new in this build.

[@jimmyj2563]

Nice to see someone doing the hard work and making a really drivable fun classic.. as someone from a transmission background I appreciate how much went into getting that right!

[@peted3637]

Epic combo! Beautiful car! I have a ZF8 in a 2.8 turbo E30. Best trans swap I have done to it.

How many have you done to it?

Simon and Promax are such a great team I was after a rx4 about 20 years ago and Simon sold me his personal project

[@MrAllstar]

Damn, that's one of the sweetest rotary's i've seen and drives so smoothly, that must be a 8-spd ZF box he was referring to?

[@Highlander1432]

Yessir ZF is also used in BMW X3m Toyota Supra Dodge Hellcats

[@liddz434]

That's schmick as! Never thought I'd see that sort of combo...cool to see old and new come together like this.

[@getahanddown]

Damn right 2 speed or bang shifters are all cool till you start street driving. Same with 'race clutches' when you can get good clutches that don't give dead legs. Also quiet exhaust on a car you want to take across county will save so much fatigue.

[@jameshatton4211]

Multi plate clutch is the only way to go unless your want to be doing right l leg calf raises to compensate for your left "clutch leg" hahaha Once you've had a multi plate clutch, you'll never go back to a HD single plate ever again. There's just something cool about stopping at the lights, selecting 2nd gear and then dumping the clutch and just being engulfed in an instant smoke show......then flat shifting 3rd and blazing the treads till about 120km/h then putting your indicator on to overtake the 32 skyline your about to pass with the tyres blazing away like it's black Friday.

Watching the video of this stunning RX3 saddens me. Of all the cars I've ever owned since 1989, I miss my very first car most, which was my Savannah RX3 . To this day, I wish I never sold her. 😔

[@craig19721000]

I know the feeling I've sold my 1 owner rx2 and my late father's rx4 many years ago but I still got my s2 rx7

can relate , priced one out of japan in 'original condition' a couple of years ago 117 G , we should all write to mazda , get them to do a remake , every one else has .still a very pretty car .

Just finished watching your video on the Mazda RX3 Mazda rotary probably the best car they ever built. A friend of mine I used to work with many many years ago had a Mazda RX4 with a RX7 motor in it two-door coupe white in colour seriously beautiful car had some power in it with a manual gearbox keep up the good work Full Boost 👍

[@pablowvangreenlow7430]

Now that's a cool car . Promaz always standing out with great work. 💪💪💪

[@occasx]

That accent is something that exists only in Sydney Australia. those shifts seem pretty savage at low speed, as evidenced by the camera moving back and forth during a low speed shift.

[@fullboost]

The opposite of savage it shifts great. 👍

[@slartybartfarst9737]

What a work of art even part done, just love the rotary, Id ride a rotary bikes, no big HP just massive smiles per mile, Aussies get what the rotary is about and interesting engineering that is right and looks right.

[@rustymonaro184]

This rotary i could actually own not overly loud ❤ and seems to cruise really well. Even as a v8 owner i dont understand the really loud exhausts where its actually painful to be in the car for more than a few minutes in whatever its powered by 4,6,8 rotary etc.

[@Nordlicht05]

I personally hate unsilenced straightpipe exhaust. Sounds not good on my ears. Loudness aside.

[@MitchTube]

What a beautiful piece of work. Rotary perfection

[@nickmudd]

I've always wanted to put a modern 8-10 speed auto on like an old carbureted v8 and see how much better they are over 3 and 4 speed autos from the 70s-2000s

[@mechtechau]

A lot of the performance/fuel consumption gains in the last 5-10yrs have been from driveline, not powertrain. There's definite gains to be had.

[@craigsampson3386]

Not quite the same but a similar thing I've seen in FB groups is that there are conversion kits to swap out the original 4sp 4L60e automatics to the 6sp 6L80 automatic in the Holden Adventra that came with LS1s, even a kit available for 6sp TR6060 manual swapping it as they only came 4sp auto from factory, so gaining an extra 2 gears either from an auto or manual conversion made a noticeable gain in fuel economy and acceleration, especially since those vehicles weigh almost 2000kg. I'd presume the 6sp 6L80 auto conversion is doable in the normal 3rd gen Commodores too since thats what the Adventra was based on.

[@MrTurboRotary]

Other day here in perth WA, saw a RX-3 RE12 on the back of a tilt tray truck, it was immaculately clean looking car no plates. Then the day dreams of me owning one when i was a teen, back in the days when you could still find them. That would have to be the first RX-3 i have seen in 20 yrs.

[@bigmattolly4910]

Good to see some of 8hp filtering through. 👍

[@thenetworkguy_]

That’s ridiculous how smooth it is

[@mechtechau]

Rotary + ZF is actually a great combo as a big turbo rotary develops less torque then an equivalent piston engine and there's correspondingly less clutch loading on gear changes. Mazda, are you watching???

[@PANN1Cau]

Wow! What a build and it’ll only get better. Would love to hear how they got it to fit into the tunnel and whether it required a lot of work or not.

"Just an absolutely SICK build... Can't wait to see how it turns out!"

[@Slipperystick73]

That’s phenomenal with the 8 speed!!

[@Flying_Fetus]

A guy I know drives an 8HP MKV Supra thats set up with a PRNDL keypad, sequential style push-pull shifter, and a second DBW gas pedal where a clutch pedal would be. I've only ridden in the car but its nearly indistinguishable from a hot DCT in an M4, plus it clutch-kicks just like a regular straight drive would. Really neat bit of kit. I'm seriously considering squeezing one into my next Miata build (which will be 13B turbo powered). DomiWorks makes the bell housing and torque converter adapters and HTG does the TCU. All in its still cheaper than a T56.

[@Tk-ou9ec]

I really like this! Especially that smooth auto. However,personally for me I find that those rear wheels look ridiculous being that big. Doesn’t look right

[@bposavec91]

the box that’s in my x5. it’s a great thing, soft as you please or sharp and quick shifting when it needs to be.

[@edinarnautovic3114]

Very nice build everything on this car looks amazing, only thing I would personally is change is the wheel size/diameter, I feel like they are a little too big for that car, but I understand if you needed to accommodate bigger brakes for the vehicle. overall great build!

[@richardhoulton4016]

Agree, the rim size looks ridiculous. Which is a shame.

[@dazaspc]

Nice to see an RX3 coupe. I tried to find one that wasnt rusted out in the early 80's and still had to settle for an RX4. The 8 speeds seem to stand a bit of abuse in the 4WD's but those ZF parts are never cheap compared to a GM trans. Looking forward to the second episode even if it is just to see how long the tail shaft ended up being.

Total dream car! Especially with that trans in it

[@rotaryperfection]

I have a 94 FD with 20b swap I DIYed back in 2007. I'm mostly a manuel guy. Really digging the idea of doing this swap. Hearing what a 20b sounds like as it quickly rolls through the gears of an 8 speed made the 20b sound even more exotic. I have a quiet exhaust as well. This has my attention, and I'm seeing these transmissions, CHEAP on ebay as we speak. Edit: Nevermind. I forget that traditional autos are rpm limited and my 20b is NA. 😞

[@Hey_zues420]

That's trans makes that thing look like a dream to drive around all day everyday. If del all my other cars and take this as my only car if I had to

[@joedipietro2559]

This is beautiful but my only complaint is that the electronics kind of take it away from being a classic retro style car. I know its 2024 and nobody uses points and old fashioned ignition units anymore but computers in cars ruin it for me. I think i might be a rare breed but an old fashioned carburettored V8 that can be repaired without a computer is a bonus to me. Beautiful mazda none the less though. Great work Pro Maz 👍👌
