Datsun Bro: Meet Japan’s 510 King
A Bluebird That Stirs The Soul

Kandou. If you’ve ever been to Japan or watched a Japanese movie, this is a word you may have heard. It basically translates to being deeply moved emotionally. You might hear the phrase kandou shita uttered at the end of a great film or after an especially well performed piece of music.

In the case of us car lovers though, it’s entirely possible to have feelings of kandou after encountering an especially amazing automobile. And during my most recent Japan adventures, there were a pair of cars that really left an impact on the senses.

One was Yusuke Sakurai’s beautiful yellow AE86 Corolla; a car which you read about here on Speedhunters last year. The other is this one – a 1970 Nissan 510 Bluebird owned and built by Mr. Akio Hirano, better known as ‘Thunder Hirano’ to his friends and colleagues.

Hirano-san spends a good amount of his time doing the same things us Speedhunters do, traveling around taking photographs of cars and writing about them for a number of Japanese publications. And when he’s not doing that he can be found wrenching on his well known Bluebird 1600 SSS four-door.

Together with his good buddy Hirohisa Hosokawa, whose turbocharged orange 510 we saw last month, the two gearheads are known as the Datsun Bros., and they share a passion for 510s that goes back to a time before many people reading this were even born.

Hirano-san’s 510 has been constantly evolving in the 20-plus years that he’s owned it, and he’s never been afraid to try new things and push the envelope when it comes to modifications. In its present form the car is both beautiful and incredibly functional; a classic Japanese icon with the perfect amount of modern technology and international influence.

No Turbos Needed

These days it’s not uncommon to find 510s with SR20 swaps beneath the hood, but when Hirano-san first attempted his swap a couple decades ago it was treading new ground. In fact, he believes it might be the first SR-swapped 510 in the world. Whatever the case, when the hood goes up on Hirano’s Bluebird you can’t help but be amazed at the immaculate engine bay. And the first thing you notice is the lack of a turbocharger.

Rather than boosted route that his fellow 510 bro Hosokawa went, Hirano’s car is a work of naturally aspirated art. He didn’t just drop in an SR20DE and call it a day though; he fully reworked the engine for maximum response and a very healthy amount of N/A power.

Inside the engine there are Tomei rods and pistons from a Nissan Pulsar, while upper RPM power is improved by a set of HKS solid lifters and a pair of Nismo N2-spec camshafts. There’s also a one-off N2-style header that perfectly rounds out an engine bay overflowing with detail.

Oh yeah, there’s also the set of Formula 3 individual throttle bodies which look positively beautiful coming off the SR, and sound just as good when Hirano opens up the car on the street or the race track.

The engine bay is not just aesthetically pleasing and functional, but you get the sense that the whole thing was put together by someone with a very deep knowledge of the SR20 and the 510 platform.

Pop the trunk and you’ll find a neatly installed Aeromotive fuel cell along with a battery that’s also been moved to the rear for better weight distribution and to further simplify the engine bay.

The engine is mated to a Tomei close-ratio gearbox, while a driveshaft from The Driveshaft Shop sends power to a Nismo LSD-equipped rear end. And yes, the car sees plenty of drifting action when it’s not winning awards at car shows.

Detail Is Key

Just like Hosokawa’s turbocharged car, the steering has been converted to a rack and pinion setup from an A31 Cefiro, while a set of adjustable Kanden coilovers and Refresh 60 rear camber arms help keep the 46-year-old chassis under control.

Braking performance has also been improved dramatically with AP Racing 4-piston calipers and 310 millimeter rotors at the front end.

The wheels are forged Barramundi Tomans from Hirano’s friend Miyamoto-san of Common Snapper fame. They measure 16 inches in diameter and do a fine job balancing the vintage and the modern in one very tasteful package.

The body of the Bluebird is coated in a very subtle shade of metallic gold/green, and the whole exterior is very original save for a Datsun Bros. carbon fiber hood and carbon fiber chin spoiler.

Datsun-Bros-87 copy

Inside the cabin of the 510 you’ll find a mix of things that are as equally fitting for a car show as they are for a track day. There’s a custom rollcage, but it’s been wrapped in leather upholstery.

Datsun-Bros-89 copy

Both driver and passenger ride in Status Racing bucket seats with Simpson harnesses to ensure everyone stays securely in place during those drift sessions.

The instruments have also been upgraded with pieces from Auto Meter, including a digital speedometer and tachometer. The Grip Royal steering wheel is one of the parts Hirano-san scored during one of his many trips to the United States where he’s a regular attendee of events like JCCS and SEMA.

Datsun-Bros-92 copy

And while the car is built on the 510 sedan platform, there’s no room for any back seat passengers to ride. Just like Hosokawa’s orange car, Hirano’s 510 is no show car but it certainly has the detail of one.

Datsun-Bros-110 copy

Akio Hirano’s Bluebird doesn’t just represent one of Japan’s cleanest and most impressive 510s; it’s a car that represents over two decades of evolution at the hands of someone who lives and breathes vintage Datsuns. This shows the moment you first catch a glimpse of it.

And I know I’m certainly not alone when I borrow that Japanese word kandou to describe how I feel about this little green Bluebird and the passion of the man who built it.

4 Years ago i was fortunate enough to get a ride in this car before it's latest was awesome then but even more amazing now...and it rips....scared the crap out of me as we headed down the street for the best ramen in Japan lol


I went absolutely ga-ga for the orange 510, and this is the perfect counterpart to it. Datun Bros couldn't be any more apt for the duo.

Simply beautiful.


Kumho V700 tires should be listed as a mod. it's a tire built for performance, as much as any other mod listed 


I'd say it's a very unique friendship here

Well done. What a nice ride.


I love it <3 Small compact fun and refined.


I'm never selling mine. Bought it bone stock and have since dropped at KA24DE in. To me it's the best car in the world simply on the principle that this car gave me everything I desired in a first car.


@JonathanLake Wagon love friend. I feel you. My first car too, daily drive the hell out of it. 


@MTDatsun Nice!! That's the color I want to get my second wagon in. I want to turn the one I have now into an ultimate grand tourer and when I scavenge up enough for another and move to a more classic car friendly environment, I'll make my second a screaming death trap. 



Possibly the best 510 in the world? Best I've seen, for sure. THIS is the standard we hold Speedhunters to!


Very cool build! I like a lot of what the builder(s) did with the car. A little bit of show with a lot of good. The details look great with a touch of unfinished areas.

I would love to drive this car for a day.


Simply amazing!! I'm partial to 510s, but this might be my favorite car ever on SH. It is absolutely perfect!



Thank you for giving us Datsun heads such cool eye candy!

I love everything about this Dime

Question to the audience:

If you are building an all-out NA SR wouldn't you use the VVL head? In the states these are relatively cheap, maybe not the case in Japan?


@SW1 I wouldn't just because it's not necessary. You can get the same performance (relatively at least) out of a regular RWD head. Just seems like a lot of headache for what, 15hp? Not to mention a moderately built NA SR pushing 170 at the wheels in a 510 would be more than fast enough (the original BRE race cars only made about 180-190 for perspective). 


@MTDatsun   Actually it's a great head swap. I was pushing 200whp with my SR20VE in my old blue 4-door. I currently have a white sedan 4-door with a SR20DE EFI swap, and let me tell you, it isn't anything compared to my old VE set-up. You can do the VE head swap for around a grand now if you get a tuned ECU...I was running Haltec with ITB's. Being a guy that owns a DE EFI set up currently and built a VE ITB head set up, the VE is way better, and I miss that power. I'll be going VE in my current 510 next year.

This is car modification done right. This car is incredible, heck, it's beyond incredible. While being a 40+ year old chassis it can still give most of its modern contemporaries a run for their money. Heck, to build all this and to piece it together might still cost less than a brand new Nissan Maxima. So why buy a modern battlebarge (forgive my WH40K reference here), when you can get an old 510, inject a few dozen thousand dollars into it coupled with love and care and on the output you will receive a vehicle that will:

1. Turn heads (apparently it is a thing nowadays, so let's just put this here)

2. Be fun (and I mean FUN)

3. Provide #2 for years to come

4. Continue to evolve into an even better self to improve #2, #3 (and #1)

P.S. N2 spec camshafts? Toda?


Finally, the other twin :).
When I saw those sort of beauty, I think I'm definitively born in the wrong land (Yeah I know, we have Spa Francorchamps but still ... :p )

Nice pictures, think I 've some new wallpapaers for my office computer :). Thanks
