2006 LS3 NC Miata $49,995.00 USD


Up for sale is my 2006 NC Miata with the V8 Roadsters LS3 conversion. Chassis number 3 out of 11 built by Steve Leonard from V8 Roadsters who developed the LSX kits for all 3 generations of Miatas. The kit is now being sold by V8 Roadsters and Flyin Miata for $42,000 plus the car. Iíve had the car for a little over a year and have done a tremendous amount of work to it. I had purchased it from a guy down in GA who had Steve build it for him for track days and time trial events. He had the car after it was built for about 4 or 5 months and was building a new house and decided to sell it. When I got the car it had 3400 miles since the build, currently it has a little over 11,000. This car played a big role in the development of the kit and especially chassis components. I used the car for SCCA and other local autocross events and due to the forces of auto crossing on slicks we found the weak links in the rear sub frame and differential braces.


The kit basically consists of a brand new LS3 crate motor, tubular front sub frame, GM Performance ECU, all electrical wiring and wiring harness, brand new Tremec T56 6 speed transmission, aluminum driveshaft, custom rear axle, diff and sub frame bracing and Ford 8.8 rear with LSD.


This car has a lot more than that and I am the type of person who does things right the first time and I appreciate quality parts and workmanship. In life you get what you pay for. I am going to list everything that has been done to the car and where it was either purchased and/or installed. I am not listing prices for each part or modification because I donít want to make myself sick.


The car is absolutely AWESOME. It has taken a bunch of FTDís at local autocross events, and garners a ton of positive attention. Everywhere I go people come up to me and want to talk about the car. It looks mean as hell, sounds totally incredible and is a blast to drive. Also people always ask ďhow can that car hook up?Ē Itís a pretty silly question but that has to do with physics. The LS3 motor only weights 50 lbs more than the cast iron 2 liter motor that it came with. We have moved the battery to the trunk, and with the heavier rear diff the car still remains an almost perfect balance of 50.5% front and 49.5% rear. Itís basically a C6 Vette minus 800 lbs. Car weighs approx 2650-2700. Rolling stock are the R888ís for the street which are 100 tread wear super sticky tires. The only reason a car spins the rear tires are if the tires are being overwhelmed by weight. I own a 500 plus RWHP NA Miata that weighs 2100 lbs and it hooks perfect as well. I took the LS3 NC Miata out a couple weeks ago after not driving it for a couple months due to snow etc and I was literally giggling to myself and hooting and hollering like a cowboyÖ I always keep the car garaged and never drive it in rain, snow or salty roads. With that said it is also very smooth, it has a smooth ride than my 2012 Audi S4 if you could believe that. From a mechanical standpoint it is in tip top condition and itís built so damn strong at this point that I highly doubt new owner will have any issues.


It is a 2006 so the paint isnít perfect but still looks great. Its got a couple little scratches and dings. The car has AC but it is not connected at the moment but I have the V8 Roadsters AC connector part which will be included with sale. I believe car had about 130,000 miles on it prior to conversion. Essentially at this point there is nothing left of that car as the whole chassis is new, new shocks, springs, sub frames etc. So one can buy with confidence. And any serious buyer is welcome to have the car inspected and if they are local to come and drive the car.


This is by no means a fire sale or any type of act of desperation on my part. Iíve got 6 cars and wanted to take a stab racing in SCCA SOLO SSR Class in a new C7 Vette and wife already wants me dead, so 7 cars ainít going to happen.

Mazda engineers urging execs for more RWD models

Wed, 02 Oct 2013 13:01:00 EST

According to Edmunds, Mazda engineers are pressuring the company to create more rear-wheel-drive models, in an effort to better differentiate itself from its rivals. This push is reportedly coming from middle and senior engineers within the company, and these folks at Mazda believe this rear-drive strategy would allow the automaker to produce more distinctive, fun to drive cars. Mazda discontinued the rear-drive (and rotary-engined) RX-8 a few years ago, leaving the MX-5 Miata as the company's only RWD offering.
As enthusiasts, we're fully on board with Mazda offering more rear-drive cars, but unsurprisingly, the company's top management isn't exactly keen on the idea - and with good reason. First and foremost, the cost associated with redesigning fresh architecture for new models would be very high, and considering the fact that Mazda hasn't exactly been raking in the dough lately, an expensive new venture like this doesn't make a whole lot of sense. What's more, Mazda's latest front-drive models - the Mazda3, Mazda6 and CX-5 - have been very well-received, and are helping the company gain sales momentum.
But that doesn't mean there aren't other options. Edmunds reminds us that Mazda is already partnering with Alfa Romeo on the next-generation Miata, and if this collaboration is successful, perhaps the relationship could bear additional fruit. After all, Alfa Romeo is said to be working on returning to its rear-wheel-drive roots, so Mazda's engineers might be able to make a case for more RWD goodness after all.

Hyundai, Mazda and Ford offering support to victims of Colorado flooding

Tue, 24 Sep 2013 16:30:00 EST

Hyundai, Mazda and Ford have initiated programs to aid victims of the recent floods across Colorado. Hyundai is stepping in to give help directly to drivers, offering those with flood-damaged vehicles a $750 credit on a new Hyundai. "At this stressful time, the last thing flood victims should be concerned with is how they are going to replace their water-damaged or destroyed vehicles," Dave Zuchowski, executive vice president of Hyundai's American sales, said.
The Hyundai program will run from September 18 through the end of October, and will cover all citizens in counties declared disaster areas by FEMA. Residents will need to provide proof of residency and a letter from their insurance company describing the damage to their vehicle.
Mazda, on Friday, announced that it'd be donating $25,000 to the American Red Cross and a further $15,000 to the Humane Society of Boulder Valley, in the name of disaster relief. Mazda's President and CEO, Jim O'Sullivan, said, "The flooding across the states of Colorado, Texas and New Mexico has been absolutely devastating for not only the people living there but their four-legged loved ones as well. Mazda hopes that those in need can get the help they deserve through such great organizations as American Red Cross and Humane Society of Boulder Valley."

Dealers think Mazda's new Mexico plant will increase Mazda3 sales by 20%

Mon, 27 Jan 2014 08:00:00 EST

Mazda3 sales in the US were down about 15 percent last year to a total of 104,713 units. According to a report from Automotive News, though, the slowdown in sales has been due more to production constraints than demand.
Good news for Mazda dealers, then, that a new plant in Salamanca, Mexico has just come online. Tom Carey, chairman of Mazda's national dealer council, told AN, "We're going to be in good shape because of that Mexico inventory." If estimates prove accurate, sales of the Mazda3 will increase by about 20 percent when the new plant begins production this month.
If those lofty projections come to pass, Mazda will reportedly be on track to exceed 300,000 total sales in the US in 2014, which would represent the brand's highest figures since its 375,000-unit peak in 1994. The brand hopes to sell more than 400,000 vehicles in the US by 2016, and with well-received products like the latest 3 and Mazda6 sedan, such expectations seem quite possible.
