Popular Bosozoku cars: Tomica Nissan Skyline KDR30

December 28, 2009 in Popular Bosozoku cars

Last week the poll decided the Tomica Skyline KDR30 as a winner in the sudden death between this car and the Impul Silvia Turbo S12. Therefore I feature a Popular Bosozoku Cars special this week: the Tomica Skyline RS Turbo KDR30! :)

The Tomica Nissan Skyline RS Turbo KDR30 Super Silhouette
The Tomica Nissan Skyline RS Turbo KDR30 Super Silhouette

The Super Silhouette Formula was fully according to the rules of the FIA Group 5. In 1979 the rules were changed to Generation 4 in which the FIA allowed the so called “Special Production Cars” in which the FIA allowed cars falling in Group 1 to 4 can be modified extensively but restricted the width, the height (roofline) and the shape of the car to remain original (hence the silhouette name). The loophole was that is only accounted for the body of the car and not for the fenders and therefore cars were still standard width but featured the ridiculously wide fenders. Maybe you can best compare the Super Silhouette formula cars to the current modern DTM racers with their big winged silhouette cars.

In Japan these series were new and were used as a warm up of the Fuji Grand Champion of the year. After 1982 the FIA changed the rules of the Group 5 in favor of Group B, however it continued in Japan as opening races for the JSPC during 1983 and only two races were held in 1984.

After years of absence in production car racing Nissan intended to fully dominate the new group 5 series and returned with a set of Fairladies in 1979 and lost. In 1980 and 1981 private teams used a Nissan Violet 710 and a Silvia S110 and Nissan supplied them with parts like the LZ20B engine. The S110 only had two wins during those early years In 1982 they teamed up with Nissan and had a line up of the Skyline KDR30, Silvia S12 and the Bluebird 910.

And it worked: the Tomica Nissan Skyline KDR30, driven by Hasemi Masahiro (a former KPGC10 driver), dominated along with the Impul Silvia Turbo S110 in 1982 and the S12 in 1983, driven by Hoshino Kazuyoshi, the Super Silhouette formula series in 1982 and 1983 while being backed up by the Bluebird KY910. The Skyline KDR30 had a total of 7 victories: 2 in 1982 and 5 in 1983!

Based upon the shape of the Nissan Skyline RS R30 the Tomica Skyline KDR30 was one of the most powerful cars in the Super Silhouette formula. Note that the Skyline RS Turbo only was for sale after the Tomica Skyline KDR30 raced for over a year! Also the RS-X Turbo Tekamen (???), as known as the Iron Mask, was launched in august 1983 which is almost at the end of Super Silhouette Formula era. The car never got facelifted to match up with the RS-X new front end.

Huge spoilers were needed to keep the car on the ground and even the rear end was lengthened to create even more downforce on the rear wheels. To keep the weight down (1005kg!) the car featured a tubular chassis with only partly a monocoque design of aluminum. All exterior was made from fibreglass and of course they needed a 2 liter racing spec engine to power this beast.

The car featured the LZ20B engine. The LZ engine was back then the racing spec engine by Nissan and was based upon the L engine (many flavors) featuring a different head with a 16 valve twin cam. So the LZ20 was basically an overbored L20 engine (2082 cc instead of 1952 cc) with a special twin cam 16 valve head on it. The LZ20 engine was first used in a Nissan Violet A10 doing a safari rally and later on in a Violet KP710 SSS and featured in many formula race cars later on.

The LZ20B used in the Skyline KDR30 was improved a lot over the years and featured electronic fuel injection and turbo charging through a T05B turbo. It was able to output 570ps (563bhp) at 7600 rpm and delivered 539 nm at 6400 rpm. The competing Silvia Turbo S12 and Bluebird 910 did also have the same LZ20B engine but both were entirely different tuned: some sources say the Silvia was only capable of 500ps and it did that at 8000 rpm. For the Silvia it didn’t really matter because it was much more streamlined than the Skyline and Bluebird.

To keep the car on the track SSR provided the front rims of 15 inch and the rear rims of 19 inch in diameter. Note that the turbine lookalike rims only featured during the 1983 and 1984 season: in 1982 it featured Rays mesh type rims as seen in the picture above. The Dunlop tires were 270mm wide and at the rear 350mm, that is almost as wide as the current Formula one spec! Also the car was slowed down by four Lockheed disk brakes with four pistons per caliper!

In this old video you can see a highlight on the Skyline KDR30:

You can really see the LZ20R, the intercooler and the big lockheed disk brakes well in this video.

And in part 2 you can see it perform during a race:

Also this car gets confused with the Group C Nissan Skyline RS Turbo C which also featured the number 11 in some occasions. It looks quite similar but is not the same car. This car was ordered by a Nissan dealer in South Africa to feature in the Kyalami 9 hour endurance race in 1982 and had to meet the Group C specifications. It is lower than the Super Silhouette Formula counterpart (different height regulations) and has a different front and rear. The car was used in a few other Group C races as well but was never really successful.

Nowadays the car is still regarded as an incredible piece of history. It marked the return of the Skyline to the racing circuits which was very important for the Japanese audience. It even resulted in the hope the GT-R designation would return on the Skyline but Nissan waited with that till 1989 with the debut of the R32. You can still buy lots of merchandise around the Tomica Skyline KDR30 Super Silhouette formula: diecast models, model kits, posters and it even featured in Gran Tourismo 2 as a price car in the 80’s Sports Car Cup. :D

The funny thing is that I was unable to find a Tomica diecast of the Tomica Skyline KDR30 Super Silhouette so far… So if anyone found one: let me know! ;)

I really understand why the looks of this car got copied in so many ways: it looks like an unleashed beast when driving on the circuit! It was an incredible and outragious car at the same time! And eventhough it only shared its front and tail lights with the original Skyline RS it is still an icon for the whole Skyline R30 generation.

Popular Bosozoku cars: Nissan Fairlady S30 part 2

July 9, 2009 in Popular Bosozoku cars

Some time ago we did a feature on the bosozoku style Nissan Fairlady Z S30. This week we feature a video with Daijiro Inada looking at the Nissan Fairlady Z S30 (and its successors) including a very nice bosozoku styled version of a Grand Champion Fairlady Z copy by Daisuke Shouten!

Part one:

Very funny to see Nomuken making the mistake of how to start a carburetted car: he wants to start the Fairlady by turning the ignition key. Lucky enough they show him how it is done properly. Funny enough: Daijiro Inada can’t drift, but surely he can start a carburetted car properly! :D

Part two:

Note that this bosozoku styled Fairlady Z has the rear lights of a Skyline C210 Japan and a (badly fit) G-nose. In my opinions this is one of the best looking bosozoku styled Fairlady Zs I’ve seen so far!

Popular Bosozoku cars: Nissan Silvia S110

June 19, 2009 in Popular Bosozoku cars

It was inevitable: one of the Silvias had to feature sooner or later! This week we feature the Nissan Silvia S110, the car that became famous through Kazuyoshi Hoshino during the Super Silhouette Formula till the cars appearance changed to the newer Silvia S12 bodyshape. This car inspired many Silvia S110 owners to convert it into a Grancha style lookalike!

This one is a very very accurate copy of that S110:

And this one a bit less accurate:

And it is even not the hatchback!

And this pimped out shakotan styled Silvia S110 doesn’t look too good either:

But that’s a matter of taste of course… ;)

The predecessor of the Nissan S110 was the ill fated S10: a “traditional” looking sports coupe with a not too hot engine. It was a big failure in Japan and got easily outsold by the Toyota Celica (and the Carina hardtop coupe) and Mazda RX5/RX3. Nissan decided to make the S110 the best car ever! Nissan saw the immense popularity of the rotary Mazdas and thought a rotary engine would be the solution. They forgot that Mazda already had 15 years of experience in rotary engines and Nissan’s attempt was a big failure: it proved to be very unreliable. Nissan decided to release the car with the new Z engine instead to get the production started.

There are actually two cars with the S110 chassis number: the Gazelle and the Silvia. The Gazelle had a rectangular grille, just as high as the headlights, while the Silvia has a slightly narrowed grille. The Gazelle/Silvia were produced that all Nissan dealerships could carry the S110. The Gazelle was only sold in Japanes and Australia while the Silvia got exported to Europe and the US (as the 200sx).

The Z engine featured a 1.8, 2.0 and 2.2 liter displacement. The S110 really got its excitement after the introduction of the FJ20E with its facelifted RS model: the DOHC 4 valve EFI 2 liter engine produced 150HP. It featured a big port with dual valve springs and a wide angle bucket on shim valvetrain (only found on the Nissan S20 engine before) and was essentially a blueprint for the later RB and CA engines!

The interior was basically an incarnation on the space age designed interior of the Silvia S10. It had a wide console stretching over the transmission tunnel. The material was, like every other late 70s/early 80s car, basic plastic in a two tone scheme.

Outside Japan the Nissan Silvia S110 also had a strong rallying following: a UK company called Blydenstein created a homologated version of the DatsunNissan Silvia S110 with a FJ24 engine: basically a FJ20E with increased displacement and a carburetor stuck on it. It dominated the British rally scene in the early 80s till it was outlawed by the Group B regulations.

In march 1983 the Silvia S110 got succeeded by the Nissan S12 in Japan. It wasn’t until 1984 that the S12 was available in other countries.

I understand why the Nissan Silvia/Gazelle S110 is a very popular bosozoku style car: everyone wants to share a bit of that Hoshino spirit! Even though I prefer the later S12 styling more, I think the car itself is a very beautifully styled sports coupe! I would drive one any day! :)

Popular Bosozoku cars: Daisuke Shouten

May 21, 2009 in Popular Bosozoku cars

Last week we featured three videos of Daijiro Inada and the Mark II platform. The poster of that video also posted part one of Daijiro Inada and Daisuke Shouten!

For people who are unfamiliar with him: he creates the most bizarre bosozoku rides! It is more a sport for him to create something exceptional than to perfection a zokusha into something beautiful!

Have a look at his bizarre creations:


I love the Corona JZT141 sedan! It looks bad and with the 1JZ swap it is bad!

Popular Bosozoku cars: Toyota Mark II platform

May 14, 2009 in Popular Bosozoku cars

Most of you probably already saw a video posted by white_raven in the comments of last weeks >rare popular bosozoku cars posting

Well this video is actually the first of a set of 3 videos about the Toyota Mark II platform. It starts with three bosozoku styled Mark IIs (RT72, MX31 and GX71), a clean tuned Mark II (JZX90) and finishes with the Verossa JZ110 drift car.

Part one contains last weeks bosozoku styled Corona Mark II RT72 and the first part of a bosozoku styled Mark II MX31:

Good detail is that this RT72 has the 8R engine and not the 8R-G, so it is not the GSS model.

Part two contains the second part of the Mark II MX31, the bosozoku styled Mark II GX71 and the clean tuned JZX90:

Note that the GX71 did get a 7M swap, so actually it became a MX71.
BTW: I love the way the tsurikawa is dangling behind the MX31 at 0:25 and scraping over the highway: the only correct way to make use of a tsurikawa! Anyone got a spare one for me? :D

And part 3 contains Hirota’s 2007 JZX110 Verossa drift car:

So a big thanks to white_raven for finding these videos!! :)

Hopefully these videos will stay on Youtube for a while, but I’m afraid they will disappear very soon…
