Last night I watched a docu-drama about Prince (the car manufacturer, not the artiste-who-used-to-be-known-as..). Some of it was rather naff, and aimed at the domestic audience. Scene of boffins standing around a Mercedes-esque sohc straight six, wondering how to extract more power. Bingo: Guru-san invents multiple carbs installation, and next scene is of motor sporting triple Webers.... :rolleyes:

However, there was lots of period film of race action. The earliest I recognised was late of fifties big production saloons at extreme angles of yaw and roll. The spirit of the rules was for cars to be stock, but Toyota manged to find a few "special" stock parts, so the gloves came off and the triple Webbers went on.

The rules must have been somewhat loosely framed, because in about 1963 or 1964, someone turned up for the prod-saloon series with a full race Porsche. That started an arms race, and the following season saw a grid full of exquisite GTs such as might be seen at Le Mans :love: . The Porsche had a very "Porsche" moment while leading in the wet, being reversed into the barriers at high speed [insert 1 finger smilie]. The Prince Skyline was victorious, and honour, well, honoured.:clap:

A number of impressive cars have been named Skyline over the years. I enjoyed the chagrin of the Bathurst Bogans when Jim Richards won in the GTR.

Anyway, apropos nothing very much other than a discreet trawl, does anyone have any background or comment on this series and the cars? Please be tolerant of my uncertainties because the programme was in Japanese, a language I have yet to master.

Cheers

Prince entered the first Japan Grand Prix with a... British sports racer, indeed a Repco-Brabham BT8, chassis # SC-64-08, re-bodied as a coupe. The car was simply fitted with the inline-6 from the Prince Skyline, fitted with hotter cams and 3 double barrel Kei-hin carbs. Named Prince R380, the car had... babies the following year, 4 new chassis copied on the Brabham design being built. The cars kept the 380 moniker, and later new versions were built as 382, then 390. Nissan purchased the ailing manufacturer by 1968.
Today, the original R380 can be seen in the Ginza in Tokyo. New paint, otherwise completely original and still bearing its Hewland HD5 tranny.

Thanks very much T54.

I'll be taking my boys to Tokyo around New Year, and I'll have my camera.

Those Keihins looked mighty like old Webers to me.

The techs were typical aging petrol-heads, with eyes going misty at the memory of winding it up on the dyno. The driver looked fit and could still pull off a 1000 yard stare.

With "Prince R380" provided by T54, Google came up with these:

http://www.ies-genev...on/GPJapon.html
http://www.toyota.co...e/a03_11_2.html

http://www.mmjp.or.j...nGPPhotos1.html
(scroll down)

And if you want to see what the Prince prod-saloons looked like, try this:
http://www.geocities...823/prince.html

The story is that Prince were an engineering-led company spun off an aviation conglomerate post-war. Their merger with Nissan (1966) brought the design and production talent neccessary to move from production of Austin based designs to cars like the 240Z.

Was a Repco-Brabham BT8 a British car?

I think it's fair to say that the Prince engine was the father of the Nissan/Datsun line that started with the 1600.

It's also fair to say that Prince Skyline GT owners had to get used to an odd gearlever pattern with the five speed box... and it must be kept in mind that the later versions of the car didn't have the triple 42mm Webers.

A very quick example was raced in NZ during the mid '60s by Carlos Neate but my old 1340cc Anglia driven so well by Donald MacDonald beat it at a feature race at Teretonga I think 06/67.
The Prince GT had megaphone pipes that sounded great but I think it had some problems during the compulsory pit stop. The same Prince GT appeared years later at some of those classic races and still sounded great.
It must still survive in NZ somewhere.

The car was indeed originally fitted with Kei-hin carbs. It now sports Webers 40DCOE but this was apparently a later modification.

The car was of course built by Aussies (and Brits) but in the UK, hence "British" car. Don't get technical with me, I have jet lag!

The pictures shown in the aforementioned websites are all of the Prince R380-2 (4 built). The original R380 is maroon in color and the body is less streamlined than the second version. The 380-2 were blue, red, gray and white. They sport Japanese copies of Minilite wheels while the original had the standard Brabham "scallop" wheels, then was later fitted with the "rear-to-front" and wider scallop wheels increasing the track by 4". There was a report and many pictures of the car in the Japanese "CAR" magazine, with many pictures identifying clearly the car as chassis SC-64-08, sold to the Prince Motor Co in October, 1964. When I suggested this to the editor of Thoroughbred & Classic Cars mag after they put a "mystery" photo that I correctly identified, they took my (verified) suggestion as a good joke. So much for objective journalism, the MRD existing records show clearly that the car was indeed sold to Prince, and that even part of the original body was used to make the coupe body. The chassis was hardly modified except for added tubing to support the roof structure.
The R380 was first modeled by Tamiya in 1966 as a slot car in 1/24 scale, but despite the hesitant shape as Tamiya was not quite then what it is now, it is certainly a model of a 380-2. A terrific story with tons of pictures was also published a few years back in "Model Car" (Japan). This mulyi-page story shows many of the cars having participated in the "Japan GP" as it was called. If anyone is interested, Electric Dreams still has copies of the mag for sale.

Today, the surviving original car at the Ginza belongs to...Toyota.

Clarification and correction.

My Brabham quip was a small incendiary to see if I could smoke out an Antipodean. Apparently not.

The triple "Weber" set up was on the sohc six prior to the second GP. The motor for the R380 was dohc, 24 valve and dry sumped. The brief shot of the induction appeared to show throttle slides and high pressure hosing. I would guess that it was injection, but I don't know. Was it Keihin FI?

The programme was on NHK and called "Project X", part of a series of Japanese discovery programmes. The good news is that it was repeated at 00.15 this morning, and I taped it. It is a nice story about how the engineers came up with a solution to avenge the humiliation of having their tin top blown away by a Porsche.

There is footage from all three GP, with a nice pan across the grid at the start of the 3rd. There is a still of said Porsche departing backwards (in the dry).

I'll bet that was a popular victory. It also left Datsun in posession of a superb twin cam six. How many other manufacturers had one of those?

They had the R380 in the studio, and at the end of the programme, one of the engineers struggled in and fired it up. They were both grinning while the hosts were literally cowering from the song.

Hardly an Allcomer David, it was road legal, heater, carpets, deck etc and we once drove in it on a Saturday to the movies [Grand Prix] in CHC. which you will know is a 730 mile round trip. Before I sold it to Bankrobber it was my everyday transport to work which was a lot of fun!

Thank you very much for all the excellent detail. Interesting to note that the museum car has Webers (see Rainer's photo) but the R380s ran FI in Australia. I guess that the editors spliced in some footage of one of the newer cars for the engine bay shots.

It's a testament to the professionalism of the engineers that they could come from production car stuff and put together a challenge to Porsche, doubtless on a miniscule budget. And also to Datsun for embracing the cultural change offered by the merger.

One is in Tokyo. Where are the others now?

Thanks all

I'm reviving this thread to alert anyone with NHK feed (that's probably only me) that next Tuesday's Project X programme will be on the engineering story behind Honda and F1.

The Prince story was pretty accurate which bodes well, and I'm hoping they have plenty of period footage. I'll certainly tape it.

Last night's story was on the development of the electronic toilet. Fascinating stuff: Toto's main man had been, Ta Ra, an hydraulics engineer at the same aircraft facility as Prince's mechanical engineers.

NZ Classic Car Magazine May 2003 had pics and an article by Tim Chadwick about Neates car and it's present whereabouts:
Built by the Prince Motor Company in Japan (prior to being bought by Nissan) the car was #186 of 200 hand built pupose racing cars and was the only privateer Prince Skyline GT-B fitted with the top spec factory racing kit outside the factory works team. Imported in 1964 by Croydon Motors in Chch it was campaigned very successfully by Carlos Neate between 1965 and 1967. Neate managed fourth overall in the 1967 championship behind Robbie Francevic's Custaxie V8. The 1988cc engine fitted with triple 40 DCOE Weber carbs cranked out 160 bhp (119kW) and now lives with Noel Sinclair in Victoria, Australia in original condition, apart from the removal of the race cam for something a little more street.

In the UK this sort of statement is descirbed as "bollocks"
However, Neate was well placed in his class of the separate Gp2 championship
And it took a good Lotus-Cortina to beat the Prince GT

From NZ Motorsport
NZ Saloon Championship
(On points for selected races; 1966-72 on points gained in engine-size classes; superseded by Shellsport Series 1978)
1967 Robbie Francevic (Custaxie)

So for Neate a fourth place outright in the championship was not possible under a points system based on engine size class placings given it was 1998cc (1-2 litre class)?

Francevic won the NZRDC Saloon Championship in 1967. This was before MANZ woke up to the widespread interest in this class. The first MANZ Saloon Championship was 1968, for so-called Gp5 cars rather than the way out "allcomers" cars such as the Custaxie, the Rod Coppins Zephyr-Corvette and the notorious Morrari.
The NZRDC Championship was not decided on a class basis in 1967 - or ever. I think Neate might have contested a couple of rounds in the Prince, but not enough to come close to any sort of championship placing. Indeed, I don't think he would have gained a single point (I can easily check later).
There was a separate Gp2 championship in 1967, and that was run by MANZ, and on the basis of engine-size classes.
Neate may have finished fourth in his class of the Gp2 championship - possibly even fourth overall. I'll check that later as well

Whilst searching for something else entirely, I came upon this old thread.

Some of what I read surprised and dismayed me. I hope that nobody minds me reviving it in order to make a few observations and corrections. I've taken the liberty of doing a bit of cutting and pasting in order to try and make it easier to read through. Apologies to the original posters for the chopping......

Anyway, apropos nothing very much other than a discreet trawl, does anyone have any background or comment on this series and the cars?

As has been mentioned, this was an episode of NHK's 'Project X Challengers' series - which ( in my opinion anyway ) was a fairly gallant attempt to reveal some of the personal stories behind Japanese products, inventions, discoveries and achievements of the last century or so. The episode called 'The Last Prince', which covers the story surrounding the Prince R380 sports racing car, was eventually released on DVD by NHK in 2005: ISBN4-7786-0151-3.

Originally posted by T54 .......a Repco-Brabham BT8, chassis # SC-64-08, re-bodied as a coupe. The car was simply fitted with the inline-6 from the Prince Skyline, fitted with hotter cams and 3 double barrel Kei-hin carbs......

.......The cars kept the 380 moniker, and later new versions were built as 382, then 390.....

.......Nissan purchased the ailing manufacturer by 1968.......

Actually, the Prince 'GR8' twin-cam 24 valve six of the Prince R380 was nothing like the 'G7' engine that was fitted the the Skyline of the same period. There were no interchangeable parts at all, and they did not use Keihin carburettors either. First GR8s used Weber DCOEs, and then went to Lucas sliding throttle injection.

The Prince - and subsequently Nissan - 'San-Per' / 'San-pachi' ( 'Three Eighty series' if you like ) sports racers had a quite complicated numbering system, with many interim and 'test' configurations that were never actually raced. These can be quite confusing, but "390" was never one of them ( that's a much later model from a different generation ) and the end of the line for the original series was the R383, which never raced.

Prince Motor Co. and Nissan Motor Co. entered into what amounted to a forced merger - with the Japanese government doing all the pushing, as it was seen to be in the interests of both parties - in August 1966. No money changed hands, but PMC was effectively swallowed up by the massively larger Nissan. Despite this, some of the Prince people fiercely protected their status as ex-Prince staff and continued to behave as though the merger had never happened. There was even some inter-factional rivalry between the two competition departments that hobbled some cars - but that's another story.....

Originally posted by soubriquet Those Keihins looked mighty like old Webers to me.

They were indeed Weber DCOEs. However, the car in the studio during the 'Project X' episode was a recently made replica, built by Shinichiro Sakurai's company 'S&S Engineering'. Dr Sakurai - a key player in the Prince sports racer and Skyline stories - was the gentleman you saw getting into the car and starting it up.

Comparing this replica to the original car(s) for the purposes of research is something of a cul-de-sac., I'm afraid!

Originally posted by soubriquet The story is that Prince were an engineering-led company spun off an aviation conglomerate post-war. Their merger with Nissan (1966) brought the design and production talent neccessary to move from production of Austin based designs to cars like the 240Z.

Originally posted by Ray Bell I think it's fair to say that the Prince engine was the father of the Nissan/Datsun line that started with the 1600.

Much of what has been written about this subject in the English language has been greatly biased against Nissan, which is quite unfair. Nissan was already striding ahead boldly before PMC was brought into the family, and any suggestion that PMC had been a heart transplant for Nissan misses quite a lot of the story. In fact, the export success of cars such as the 510 Bluebird and S30-series 240Z had just about nothing to do with PMC.

There has been much nonsense written over the years about the origins of Nissan's 'L-series' four and six cylinder SOHC engines, and much of it seems to have originated from Nissan USA's advertising blurbs. Contrary to the myth, the L16 first seen in the north American market Datsun 510 models was not the first of a 'new' breed of engine with Prince DNA, and the L24 of the 240Z was most certainly not "an L16 with two extra cylinders added on" either! The truth is the the very first Nissan 'L-series' SOHC engine ( part of Nissan's 'L-series Module' of varying sizes / types of L4 & L6 SOHC engines ) was first specified in July 1964 as a response to arch-rivals Toyota's new six cylinder engine in their 'Crown' model, and within a year the first Nissan 'L20' SOHC six would be fitted to the H130-series Nissan Cedric 'Special 6' model - this a full year before the PMC / Nissan merger.

That's not strictly true. The Prince R380 ( based on Brabham BT8 #SC-64-08 ) that is sometimes seen in Nissan's 'Galleria' showrooms at Ginza, and at the Toyota Museum, is actually part of Nissan's 'Heritage Collection' ( mainly housed at their old Zama facility, and not open to the general public ) and is technically only on loan to Toyota.




Now I need a cup of tea........... :)

We were told otherwise by the Toyota folks, but it makes more sense that Nissan would own the thing. The funny thing about this is that when I sent the info to Classic & Sports Cars years ago, they took my suggestion in utter derision and thought that I was from another planet. Oh yeah, we are making progress.

Classic & Sportscar? I sympathise with you.

Six years ago I lent Mick Walsh some very rare Japanese books and vintage magazines, for research related to an article he was working on. He has so far avoided all my efforts to have him return them to me.

I don't know what they do with them. They obviously don't read them there, do they?

As a much-derided journalist seeking the truth, I ask...

"Why is this so?"

I've had these engines apart, I've bought gasket sets for them, I know that the timing cover gasket and the timing chain and the tensioners interchange. Maybe they're a slightly different bore and stroke? I guess I could look that up.

The fact that the heads are designed in their near unique manner, with the centre two cylinders looking like they were grafted in, seems to support the common belief.

No disrespect intended, but you're possibly looking down the wrong end of the telescope. Surely you don't believe that the L16 was the first Nissan 'L-series' engine, and that all others came from it?

The ( USA origin ) advertising / PR bumph for the Nissan L24 engine, which was first seen in the north American market in the 'Datsun 240Z' model of late 1969 and early 1970, introduced it as an "L16 with two extra cylinders" - and the idea stuck. This was simply a case of the marketing people linking a 'new' engine to something that the market had already seen, and had got used to ( and, incidentally, had been told was "made for" them - which was a pretty grand claim ).

The L16 and L24 were not brand-new designs. They were derivatives of that first L20 six seen in the H130 Cedric, and shared their DNA with L13 & L14 fours and the L20 & L23 sixes of many Japanese domestic market models that came both before and alongside them.

If you really want to know the whole story about these Japanese products, it's no use looking solely at the Export market versions. It only gives you half the story.

I was aware, of course, of the Personal Six and Super Six engines...

One virtually an extended Bluebird pushrod engine, the other a nice OHC design. And I would have supposed that the 1600 engine came from that source. But I never looked closely at the 2-litre OHC six.

I guess what you're saying is that the 4-cyl engine was a cut down six, rather than the other way around. So how does the odd porting arrangment come about? Or was that, perhaps, the intinsic provision for 4-cyl production envisaged from the beginning?

That's the point, the various fours and sixes were envisioned as a 'family' right from the very beginning. Strictly speaking, the L20 six of that H130 Cedric 'Special Six' launched in October '65 was the first of this new 'L-gata' ( 'gata' = type ) family to be fitted to a production car, but the design was conceived as a 'module' right from the first design brief.

The first major revision / update of that L20 six ( Nissan internal code 'B742X' ) increased the bore pitch, and the deep-skirted block design allowed for a variety of strokes. Thus the L12, L13, L14, L16, L18 & L20B fours and the L20A, L24, L26 & L28 sixes can all trace their DNA back to the 'L20 Kaihatsu' ( Nissan internal code 'B601X' ).
