LS6 Powered Mazda Miata Track Beast

Sometimes you just ask yourself why would someone do that.  And then you realize how much you really want to be behind the steering wheel of that car.  LS6 Powered Mazda Miata.  That sounds like a good time.


I can’t believe I’m even considering this, but given my current situation (needing money for new house) the Miata is up for sale.  Soon to be followed by the truck and trailer.

I have done my best to describe the Miata as thoroughly aspossible, but I’m sure I’ve missed some things here and there.  If you have any questions, please feel freeto shoot me a PM and I will send you my phone number.

The car has never been in an accident.  I did have a wheel break once (Gotta love Keizers), but the damage was purely cosmetic (Fender and Flare).  I purchased the car 8 years ago and when purchased it was in absolutely perfect condition and had 116k miles on it.  It has since gone through a number oftransitions, including the final transition to a LS6 power plant.

The car does have some dings and scratches here and there, but overall it is in pretty good cosmetic condition.  Hopefully the picture show that, and I’m sure anybody who hasseen the car in person will vouch for it. The car does not have rust anywhere. It is very solid and has been garage kept since original purchased (Me and previous owner)

Performance and Videos:

This car is the fastest car I have ever driven, and being an AX and track instructor I have driven a lot of cars.  Consistently sets local autocross FFTD.

Very capable on the big track, even at high speeds.  Unfortunately I have only gotten a couple sessions on track before the 1st motor let go. With the original less powerful LS1 and little to no set up time, I ran 2:06s on VIR Full with a top speed on the back stretch of 158MPH.  It is definitely capable of sub 2min laps with a good driver. (Unfortunatelyonly track video)
