The ZF 8HP 8-speed transmission is quickly becoming a popular choice as a conversion option in many sorts of vehicles given their capabilities. We caught up with the team from Promaz who have recently fitted one into a wild 20B turbo rotary powered Mazda RX-3.

    It's amazing how modern car tech ends up keeping classics even better.
  • 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🇦🇺🏁
  • I can listen to Simon all day bro.. very well spoken cool, carm sounds genuine..
  • Simon and Promax are such a great team I was after a rx4 about 20 years ago and Simon sold me his personal project
  • @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.
  • @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.
  • @mrcaps1971
    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. 😔
  • That's fantastic. This is what we should do with more older cars. Not everything is scrap.
  • @A_G420
    That car is amazing. Seems like a great gearbox for a rotary honestly.
  • @5533851
    So cool. This box would be mint in a VL Calais turbo
  • @liddz434
    That's schmick as! Never thought I'd see that sort of combo...cool to see old and new come together like this.
  • @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?
  • 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.
  • @sticustom
    The last Mazda RX3 I drove had a 12B motor and it went like the clappers.
    It was no where near as beautiful at this car. So pretty. 😍
    Looking forward to part 2.
  • @madrew2003
    Not a fan of the wheel and tire choice, but the rest of it is amazing!
  • @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
  • @roysampson182
    The ZF autos are an incredible transmission. Cool to see the mix of old and new in this build.
