He Built a Miata V8 Roadster!

Last month, at the The Drivers Edge event at Harris Hill Road, I met Mark who has “improved” a Mazda Miata in a unique way.  He purchased a LSx conversion kit, from www.v8roadsters.com, which allowed him replace a Miata 4 cylinder engine with a big LS1 V8 engine (a Chevrolet Corvette engine that fits just fine).  Mark says these Miatas are “twice as nice”! This swap does a number in interesting changes to a Miata:

  • Adds 130 pounds
  • Increases the power 3 times
  • Shifts the center of gravity back better, due to the bigger engine & transmission
  • Mounts 275mm wide Hoosier tires all around (this is an increase of 25mm)
  • The tires are mounted on 6UL wheels form 949racing.com

Mark steered me to this website where you can learn more: www.v8roadsters.com Go ahead, check it out…   Quite an interesting conversion!

I’m sure these converted Miatas would be a hoot to drive!  Has anyone out there heard, seen or even driven one?

  1. I’ve heard of these conversions, but somehow they seem a little sacreligious or something. I’m sure they’d be a wild ride, but how would the handling stack up with such a radical modification?

    I guess you’ll have to track one down, drive it and tell us!

  2. Mark does excellent work! He now has my blue car…and he has lots of Miata parts if anyone needs anything. I never got to drive the last V8 before he sold it, but because you are only adding 130lbs (and some of that is in the rear with the larger diff), it doesn’t effect handling. In my opinion they need a definite brake upgrade after the swap though!
