    Thread: Custom V6 Miata - Purpose-built AutoX car

      Autoblog -

      You don't need to spend much time with a Miata to "get" why so many drivers are attracted to them. Perfectly executed and relentlessly entertaining, it's no surprise that Mazda's little roadster is the track-day weapon of choice for a number of people. While countless 4-banger Miatas do their thing on the autocross circuit, one Mark Snell was interested in kicking things up a level so he could run with the big boys in their 'Vettes and similar machinery. His solution? Drop a Mazda 2.5L V6 into his blue roadster's engine bay, then modify and tune it to the point where it's pushing 180 horsepower to the rear wheels. The view underhood is plenty cool -- we especially dig those Suzuki GSX-R1000 throttle bodies he's added. The Miata sounds pretty mean, too. Follow the jump for a video in which Snell gives a tour of his car and discusses the modifications he's made before taking viewers for a quick spin. We believe that this is what fun looks like.

      I've heard of this swap a few years ago. It may even be the same car. It's pretty badass.

      Mazda engineers made a 3.0L Duratec Miata many years ago. Read about it in C&D, I think.

      I remember that issue! They had (I think) 3 different factory-modified Miatas, one was an all-out 4-cylinder track car (yellow), the 3.0L Duratec model was red, and I forgot the other one.

      ...much earlier than that, they built one with a Mazda KL 2.5L V6 just like this one, too.

      The video doesn't convey how incredibly well-finished and engineered this car is. A lot of people have dumped bigger engines into Miatas, but this guy re-engineered this car from the ground up as a V6 using as many Mazda parts in the driveline as possible. It's really nicely done.

      Just 180 hp? Doesn't seem like much for a built up 2.5 l V6.

      I didn't hear the audio track, but that engine makes (at the crank) 164hp in stock US-spec trim and 199hp in stock JDM trim.

      Yeah, why not just go SC that way you don't have the extra weight.

      Nothing to see here move along.

      That's 180 whp. That engine is really refined and smooth...plus it sounds great. Used to have a KL-ZE powered MX-3....til it got stolen and destroyed.

      That's pretty good for a KL-ZE if all he changed was the intake/exhaust tracts.

      Yeah I thought he said the motor was pretty much stock internally.

      Hmm, upon further investigation, it appears that it is actually a KL-DE engine with ZE 10:1 pistons, an otherwise internally stock engine.

      They are actually 300hp 4.9L V8s. Yes you can get them to 500, but I don't believe MM offers such a package, besides, I think that would be overkill.

      That's actually a pretty cool conversion.


      Personally I'd love to clip one and stuff a Ford FE into the bay. Modern day Cobra, anybody?

      make shiny.

      Neat, but why not a NA Built Duratec. You can easily get that same amount of power, and potentially be a smidge lighter.

      The KL was chosen for this car for the Street Modified 2 autocross class, because it limits you to engines of the same manufacturer as stock. The Duratec might fly if sourced from a Mazda6 or MPV, but not a V8.

      It was chosen over simply force-feeding the stock engine because... the family who built it liked it that way. They were also already familiar with the KL in an MX3.
