1990 Gtus - Built With The Best - 185whp - Gorgeous on 2040-cars
Denton, Texas, United States
The most special of all second generation RX-7's: the 1990 GTUs. And this is a very fine one! Civilized enough to be driven daily, fine enough to show, aggressive enough to track. I built it to be as Mazda intended it, but a bit 'more so'. It has been a Southern car its whole life, no rust, and garaged for the majority of its life as well. Rotary Resurrection and Rotary Performance (Kevin Landers and Chris Ott) built and tuned the engine – some of the best in the business. Fly into Dallas and drive it home without qualms. First owner: little old lady in Florida who thought it was cute and never revved it past 4k. No lie! Second owner: well-respected RX7 forum member who bought it with a motor full of carbon, rebuilt it and auto-x’d it on occasion. He bought many of the aftermarket parts and had the original engine rebuilt in 2003 by Rotary Resurrection. I am the third owner, purchased May 2008. I have the original window sticker, a full Factory Service Manual, and plenty of records for it. Details Engine Exhaust Suspension Cooling Brakes Trans Fluids & Belts Electronics Interior -Corbeau A4 seats, minor wear Exterior -LOUD compressor-driven air horn hidden inside front bumper Quibbles The drive It gets going quickly with the 4.3 ratio rear end (GTUs specific) and light flywheel. The combination of good torque, RB steel flywheel, and dual-friction clutch means it’s easy to pussycat around town. The clutch grabs harder the higher the RPM’s, which is very entertaining for performance driving. The tires are a good match for the car, grippy and responsive without being rock-hard riding or too soft. Sounds amazing, angry hornet! It is stable and builds speed very quickly up to 125mph or so, at which point it starts to taper off. I’ve never wound it out. Torquey enough to ebb and flow with traffic without having to row the gearbox. The ride and handling balance is sublime. I spent years replacing and adjusting components to get a balanced, responsive ride which is sporty but not harsh. The Illumina/RB and RE Aremania combination is an excellent match: they have similar damping characteristics, and can be adjusted from cruiser-soft to auto-X firm. The Manual steering & careful alignment setup make the handling amazing. I went through 3 steering setups to find this one. It provides unparalleled road feedback with an excellent, not to fast, not too slow ratio. It is reasonably calm on the highway yet still has that 'tingle' that let's you know exactly what the car is up to. On the track, whether tight auto-X or fast road course, it is your best friend. Brakes are solid and the hotter they get the better. The HP+ pads do not have strong initial bite; they are smooth when cold, and when warmed up, Whoa nelly. They are easy to modulate and very strong. The car is fully sorted and phenomenally reliable. It has handled a dozen or so auto-x and track days without issue, chasing down much faster cars with aplomb, limited by the component behind the wheel. It's a lot of fun to fill the rear-view mirror of a Mustang or even a Corvette... in a 1300cc 24yr old RX7. It is very balanced around corners, driven by the wheel and the right pedal. Removing the weight really woke up the front of the car. Mass feels very centralized, I have not been in a more responsive, willing-to-rotate car aside from mid-engine cars from Porsche and Lotus. The car actually gets very good mileage, mid 20’s on the highway, upper teens to low 20's mixed. 87 octane. You probably never knew how much fun a quick naturally aspirated RX7 could be! The recent rebuild was done right: every component was inspected, throwout and pilot bearings replaced, etc etc etc. Throughout my ownership, I premix 1/2 oz/gal premium oil, with OMP operational as well. During the rebuild, with about 20k on the hard parts, everything was well in spec and able to be re-used. New motor built instant compression and at 185whp on a conservative tune, it is very stout. Car will come with original speed-sensitive PS and AC components if the new owner would like to convert back to stock. I waited 2+ years for this to come up, spent the last 5 years fully building and sorting it out, and will be happy to keep it if the right buyer does not materialize. TERMS

Mazda poaches designer Kevin Rice back from BMW
Wed, 30 Oct 2013Kevin Rice left Mazda a baker's dozen years ago, but now he's back.
A graduate of the Transportation Design program at Coventry University (just across town from Jaguar headquarters), Rice worked his way up in the industry working for the likes of Opel and Italdesign Giugiaro before landing a job at Mazda. Between 1995 and 2000, he collaborated on such projects as the RX-8 and the 1999 Neospace concept that previewed the Mazda2 before moving on to BMW, where the new 3 Series and 4 Series were among the last projects he worked on during his 13-year tenure in Munich.
Now back at Mazda, Rice has been named the Japanese automaker's new creative director, charged with further honing the brand's KODO design language from its European headquarters in Oberursel, Germany. We're looking forward to seeing what he and his design team come up with in the coming years.
Mazda hard at work on Skyactiv 2 engine technology
Wed, 08 Jan 2014As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
Recharge Wrap-up: Tesla road rage video, Mazda tests EVs vs. hybrids
Wed, Sep 23 2015A Tesla Model S driver was caught driving recklessly in a dashcam video. On Toronto's Don Valley Parkway, the driver of a white Model S can bee seen speeding along the left shoulder. Another car moves partway onto the shoulder to block the driver, who moves back into the left lane. As traffic slows, the driver pulls back onto the shoulder and speeds away. The folks at Teslarati suggest that this serves as an example of why vehicle autonomy could make the roadways safer. See the video above, and read more at Teslarati. Formula E will be broadcast live on Italy's Rai network for the next two seasons. The programming will include the live races, as well as practice and qualifying highlights, podium celebrations, interviews and other pre- and post-race coverage. "It's a great opportunity for Formula E and motorsport fans to have Rai broadcasting the live races of our series in Italy," says Trulli Formula E team owner Jarno Trulli. "It's a step forward to make the series grow and get stronger after a successful first season. I'm looking forward to cooperate with Rai and show the Italian fans what we are truly doing with our technology." Read more from Formula E. A new study links a decline in cancer risk to California's air quality regulations. The study from CARB found that cancer risk from toxic air contaminants declined 76 percent from 1990 to 2012, a time period that corresponds with regulations targeting those contaminants. Even as the amount of diesel miles driven has steadily increased, cancer risk from diesel particulate matter has declined significantly. The paper predicts that cancer risk will continue to drop as a result of controls on toxic emissions. Read more at Green Car Congress. Mazda is conducting consumer trials of hybrid and electric vehicles in Japan to gauge reception. Depending on whether hybrids or EVs prove to be more popular, Mazda will adopt one of the two types of powertrain for future production vehicles. The automaker is currently testing an electric Mazda2 against a hybrid Mazda3. While this round of testing is focused on the automaker's home market, Mazda may need to expand trials to the US in response to tightening regulations in California. Read more at Green Car Reports.
