EVENTS: SevenStock 2015

099 Mazda RX7 SA22

Mazdafarians far and wide came to the recent SevenStock 18, the premiere showcase of rotary-powered Hiroshima heroes. Held at Auto Club Speedway in Fontana, California, the all-day festival mixed a car show, track day, and basically anything that was Mazda rotary-themed.

005 Mazda MX6 IMSA

Mazda North America of course brought out a squadron of rotary racers from their R&D basement, including their 13B-powered IMSA GTU Mazda MX-6 and the #62 four-rotor IMSA GTO FC3S.

009 Mazda RX7 SA22 IMSA GTU Daytona

All of Mazda’s cars ran laps around the speedway, banked for NASCAR antics. This year they were joined by a very special car — their replica of the 1979 24 Hours of Daytona class-winning IMSA GTU RX-7, which the crew just recently got running again. This is serial number 00007, the seventh ‘7 ever made.

006 Mazda RX2 Car&Driver

Unfortunately, when you run the cars, things do go wrong. When this historic RX-2 came back with a hood askew and sticking up in the air, we were afraid something disastrous had happened to the first Mazda to win a professional racing event in North America.

Thankfully, it was an easy fix. The structure of the hood had separated from the skin. “Forty-year-old glue,” commented the Mazda crew nonchalantly.

016 Mazda RX7 FD3S017 Mazda RX7 FD3S

An autocross event held on the infield tarmac attracted many, including an FD that appeared to answer the question, “What if Keisuke Takahashi was actually James Bond?”

021 Mazda RX7 FC3S racing019 Mazda RX7 FC3S racing023 Mazda RX7 SA22 drag

From circuit destroyers to 950-horse drag demons, the full breadth of the rotary engine’s racing prowess could be seen just a few feet from one another.

024 Mazda REPU Angel Motorsports 025 Mazda REPU Angel Motorsports

Some insane members of the Angel Motorsports family took a drive from Virginia Beach in a REPU that looked like it had been rescued from a salt mine. To mark four days on the road, they completed a relaxing transmission swap during the show.

028 Mazda RX2 Angel Motorsports

Angel Motorsports specializes in rotary engine builds like this one. If the cross-country trip in a newly built motor is any indication, they are very good at what they do.

040 Mazda RX7 SA22038 Mazda RX7 SA22

A patriotic trio of local RX-7s, all of which had Angel-built motors, helped showcase the company’s wares.

039 Mazda RX7 SA22

One of them was an old friend, Smith McGehee, who ran the JNC Touge California earlier this year. With a new set of shoes his RX-7 is also serving as the testbed for an upcoming Koyorad aluminum radiator for first-gen RX-7s.

032 Mazda RX2 & R100 Abel Ibarra 034 Mazda R100 Abel Ibarra

We admired the Ibarra brothers’ collection of rotary gems at JCCS, but something was missing: Abel’s R100 was the car that launched his rotary drag racing career and became the first Japanese car to be inducted into the Wally Parks NHRA Motorsports Museum.

029 Mazda rotary keychains 030 Mazda model kits

Rotary keychains, pins, and model kits were available for purchase at various vendor booths. One FD kit in particular seemed to confuse the paint scheme of one famous movie star Supra. The Cosmo Sport police car, on the other hand, was supremely cool.

045 Mazda R100 046 Mazda R100

The R100 was Mazda’s first “accessible” rotary car (the Cosmo Sport being far too expensive for the average Japanese consumer in the late 60s). With a sub-1800-pound curb weight, it became a favorite for drag racers once 12A and 13B motors became prevalent. That’s probably why there are so few of R100s left today, with only three total at the entire show (and one of them an Australian import).

054 Mazda RX2057 Mazda RX2 sedan048 Mazda RX2 & FD3S 056 Mazda RX2053 Mazda RX2 050 Mazda RX2

There was no RX-2 shortage whatsoever, from candy-flake street machines to faded works-in-progress to cars that still had dealer-installed vinyl roofs. Named the Capella in Japan, it was Mazda’s second effort to create a deluxe rotary-powered sedan. Today, it would be known as the Mazda 6. At 2,130 pounds its still a featherweight by modern standards, but it was over 300 pounds heavier than an R100.

047 Datsun 510 Wagon rotary075 Mazda RX2 & Datsun 510 wagon rotary095 Datsun 510 rotary 096 Datsun 240Z rotary

Any car with Mazda rotary was welcome, but that doesn’t mean they were all Mazdas. Several Datsun 510s, including a couple of wagons, and a 240Z had had their primitive reciprocators swapped out with spinners.

058 Mazda RX3 Savant 059 Mazda RX3 060 Mazda RX3 063 Mazda RX3061 Mazda RX3 062 Mazda RX3 064 Mazda RX3 065 Mazda RX3

Don’t mind the numbers in Mazda’s naming scheme. The RX-3 was smaller and lighter than the RX-2, making it once again hugely popular for racers of all stripes. We’ve been to SevenStocks that have barely had an RX-3 presence at all, but this year they came out of the woodwork in force.

066 Mazda RX3-SP 067 Mazda RX3SP

There was even a pair of the rare RX-3 SP US-only appearance package. It’s nearly impossible to find a complete set of the SP parts, which is why only one of them has the larger air dam and the other has the side window louvers.

069 Mazda RX3 sedan 073 Mazda RX3 sedan

Amazingly, there wasn’t just one but two extremely rare RX-3 sedans.

076 Mazda RX3 Wagon

Slightly less scarce, but only by a hair, are the RX-3 wagons.

077 Mazda 808 & RX3 Wagon

Topping the rarity charts, however, is the piston-powered 808 wagon. This is the first one we’d ever seen in person, but it already been swapped with a rotary.

078 Mazda RX4 079 Mazda RX4 080 Mazda RX4 Wagon

The RX-4 was saddled by showing up on US shores right after the 1973 OPEC Oil Crisis. They are rare today, but a few made it to the show: one primered JDM Luce, a resto-modded USDM coupe, and the Ibarras’ mint wagon, which we featured in depth at JCCS.

086 Mazda REPU085 Mazda REPU 087 Mazda REPU 089 Mazda REPU091 Mazda REPU088 Mazda REPU 092 Mazda REPU 081 Mazda REPU093 Mazda REPU

The number of REPUs entered into the double digits, making this quite possibly the largest gathering of the Rotary Engine Pick Up in the world since they were at the dealerships.

094 Mazda BSeries Racing Beat

Speaking of trucks, the California Haulin’ rotary-powered B-series is quite possibly the most 80s truck ever built. Used as a Racing Beat show car, it featured a bed that carried a custom-paired jetski.

097 Mazda RX7 SA22 108 Mazda RX7 SA22 FB098 Mazda RX7 SA22 109 Mazda RX7 SA22 FB100 Mazda RX7 SA22 111 Mazda RX7 SA22 FB116 Mazda RX7 SA22 FB103 Mazda RX7 SA22 113 Mazda RX7 SA22 FB117 Mazda RX7 SA22 FB 115 Mazda RX7 SA22 FB118 Mazda RX7 SA22 FB

Not surprisingly, there was a maddening number of RX-7s. After all, it’s where the event got its name. Unlike the earlier RX models, most SA22C seemed to be comparatively tame when it came to modifications. A slight drop, some nice Epsilons or BBSes and that was it. Few emitted the ported brap brap brap that the chrome bumpered classics did.

105 Mazda RX7 SA22 106 Mazda RX7 SA22

Perhaps the cleanest first-gen RX-7 was a 1979 Limited Edition, of which only 3,000 were made. This unrestored one had only 26,000 miles and change on the odometer, and was unbelievably mint. Even the plastics in the engine bay were still shiny.

Sneaking up from nowhere was a superb Japanese zokusha-style SA22C, complete with RE Amemiya-style aero kit, an Olio Fiat street spoiler, and old school and louvers. It’s extremely rare that we see an RX-7 that looks like it came straight from Japan, so we were very pleased to see this homage to the tuning styles of the motherland.

After the SA22C, the second most prevalent platform was the FC3S. The second-gen RX-7s have not quite achieved the revered status of the first-gens yet, but a few clean examples could be found.

131 Mazda RX7 FC3S

This Series 4 GXL was the cleanest one at the show.

136 Mazda RX7 FC3S convertible

The quintessential California cars.

142 Mazda RX7 FC3S140 Mazda RX7 FC3S146 Mazda RX7 FC3S

There’s just a couple more years until the FD3S achieves proper 25 year classic status, but it was encouraging to see at least a few owners that opted for minimal or clean modifications.

147 Mazda RX8

Not quite nostalgic yet, but here’s a row of monochromatic RX-8.

148 Mazda3

Where there were classic Mazdas, there were modern ones. Someone’s Mazda3 daily driver lurked beside the paddocks. Brand loyalty runs deep with Mazdafarians.

Last but not least, our favorite car of the show was this replica of the second 24 Hours of Daytona IMSA GTU racer. Those stripes aren’t decals, they’re painted on. The owner bought it from an 80-plus year old lady who kept it pristine even though it had over 300,000 miles on the chassis and was on its third engine. A chance discovery of a Pacific widebody kit became the inspiration for this Daytona tribute. Look for a feature on this car in the future.

    Great article Ben. Nice to see so many FC’s.

  2. j_tso says:

    Funny about the RX-2 hood, I read about a case of that happening at an early IMSA RS race so there was a run on rivets in the pits.

    The photos of I’ve seen of the 1979 Daytona 24 RX-7s have them both being left hand drive. I’ve heard this car Mazda is showing around is an early chassis development car.

    • Dave Yuan says:

      This particular car is a very nice replica of the original Daytona race car. It’s actually the 7th RX-7 off the production line (by VIN). It’s RHD. The RX-7s that raced at Daytona in 1979 were LHD.

    • Ben Hsu says:

      j_tso, of course you are quite right. I didn’t make that clear initially. I even wrote a whole article about that specific car but sometimes it’s all a blur!

  3. atx says:

    Dang i really need to get my fb going… Those pics are lust worthy.

  4. james says:

    One of these days, I’m gonna have to take a trip to Cali to attend this event.

  5. Scotty G says:

    Great article and photos, as always. How does a person fix (as in, “It was an easy fix.”) a separated hood like that without ruining the exterior finish? I’ve never heard of that happening.

    And, Mr. Ibarra’s orange RX-2; that’s a painfully beautiful car! As is their red RX-4 wagon. Man, what a dream collection those gents have.

  6. Tom Westmacott says:

    Fantastic set of photos, really got my juices going seeing so many beautiful, purposeful rotaries milling around like that.

    I have a feeling the tide has about turned on FD modifications, there’s more emphasis on the stock body (and about time too!). I’ve seen a few being “de-ruined” lately, which always brings a smile to the face. They seem to be rising in value (at least here in the UK), so I think, despite how things seemed until recently, that they will in fact be preserved in decent numbers as classics.

  7. No Salsa says:

    I can’t believe how many Rx2 coupes you guys got, dime a dozen. I’ve always loved the very first Australian models with the vented bonnet and square headlights.

    As for R100s , Rx2 sedans and Rx3 – 4 coupes and sedans they are easy enough to find here. They all sell at a premium these days here though. I’m lucky to have both a 3 coupe and sedan before prices went up.

    Nice converage.

    • David Meyer says:

      RX2s are hardly a dime a dozen here. When you can find them, you pay dearly for them. But in a metro area of over 18M people, there’s bound to be a handful of people with them. 🙂

  8. Michael says:

    I guess mesh wheels are to American Mazdas what Simmons wheels are to Australian Mazdas.

  9. UCHE says:

    The event this year was definitely Nostalgic heavy. Being an FC guy, it was dissapointing seeing some of the examples, nothing had a strong presence. Overall, glad the FBs came out strong and it’s all Mazda love at the end of the day. As I always say, I’ll try and make it in my Mazda for next year 😀

  10. psyaddict says:

    what are those wheels on the first picture under the white sa22c? are they japan racing jr-14?
    i´ve been wanting something like these for my fc3s..

  11. Thanks for coming out once again Ben and covering the JNC side for us… your products were on-point too!!

  12. David Meyer says:

    Great coverage! It was great to meet you guys…I’m honored that you chose my FB as your favorite!

  13. Yoda says:

    Dig how the new Mazda 3 five-door’s Coke-bottle effect echoes the RX-3.
