Really? That easy Alan? Darn... I just passed one up. Well that will teach me...

Is it any easier to find rebuild parts for the R190 LSD than the old R180 LSD?

I'm thinking such items as clutch plate sets (the LSD is a clutch-typeright?), seals?

It would be great if someone put together a book on the racing Z cars, particularly the Japanese ones with detailed information on factory variants, numbers made, etc. Not only for interests sake but also for a very practical reason. Which concerns the eligibility of certain variantions and equipment for historic based competition events.

For example, targa type events are very popular in Australia, quite a few S30's participate but it is very difficult to establish what they are eligible to use in the way of improvements over standard. Consequently they are often up against other optioned up cars but still do well, eg second in the very popular Classic class this year, around 130 cars in that class.

Yes that would be an excellent idea - targa is popular in NZ now with a number of S30 taking part also.

EricB, some parts for a R190 are very difficult to find. There is one bearing in particular that is no longer available, replacement gear sets are extremely rare and rear covers and side plates are equally as difficult to find.

Les Cannaday bought the majority of R190 parts from Nissan USA when they discontinued all the parts for this differential.

If you have one that needs to be rebuilt you might spend more to fix it than what it would cost to buy an R180 with a Quaiffe. Another thing to keep in mind is that R190's came with gear sets that are not suited for street use. The most typical gear in an R190 is a 4.44 gear.

Bottom line is there are still parts available for R180's but since Nissan never supported R190's in the states (other than in of the comp catalog). Trying repair a broken R190 may not be possible any more.

John Coffey, is the last guy I know who was successful rebuilding an R190 about 2 years ago, and I bought that one from him. I use mine (I have 2) for my Vintage race car.

Ron,

A 4.44 or 4.375 is exactly what I want for my car...

If you check the math you'll see that I am running an even higher rpm at cruising speed on the freeway right now with 4.11 gears and a loaner 4speed with a 1.0 ratio in 4th...

Getting my 5spd back from the rebuild shop and mating it with a 4.375 or 4.44 rear end would actually give me lower revs for the same speed...

Eric,

I am familiar with the math...I assume that you are planning on running a ZX 5spd, and under those conditions a 4:11 or 4.44 works well on the street...

That still does not change the main issue...Parts for a 190 are hard to find and expensive.

The R190 ( called 'R192' in Japan ) was fitted as standard equipment to PGC10 & KPGC10 Skyline GT-Rs and the vast majority of PS30-SB Fairlady Zs.

Quite a few of these cars ended up with full 4-pinion units over the years as the owners upgraded them.

Parts to rebuild these diffs are still available from specialists in Japan. Expensive, yes. Difficult to find, yes. Impossible, no.

But when R200 units in most ratios are still so easy to find, comparatively cheap and simple to rebuild / fettle and fairly easy to fit in place of an R180, it seems pointless to use an R190 / R192 unless forced to do so by competition rules and regulations.

[EricB]

Aside from not knowing whether it would use R180 half-shafts/etc, I figured that since this was the first one I'd seen for sale in a long time (it was actually the stock rear end on a PGC10 that had been imported to the States) I did wonder how available parts would be for it. Thanks anyway guys.

Really?

G'day Eric, was the car a real PGC10? a 4door GT-R? or a GC10 Skyline GT? Could it have been an R192 rear end from a GT-R swapped into a 2000 GT that had the rest of its driveline beefed up? Hot "L" series etc?

By the way, the other GT-R lookalike KGC10 in Australia is up for sale. Nathan (owner) was using it more and more for circuit days and is worried as he gets faster the risk of bending it increases, so he now has a pretty little race setup 510 coupe for fun, track days, and feels 7 (it's not fair I know!) road cars is a bit much, so the Skyline is on the market down this way.

Oh, and ..arrr..sorry about all the question marks, I got 'em cheap down the markets and had to get rid of a few before they go off :laugh:

Cheers mate,

Jim.

Apologies... Yes it was more than likely a GC10 made up to look like a PGC10.

As you stated hopped up L series.

Alan,

I have been diging around in the law books and did some asking, and it seems that the rules for pre 1979 cars are not that strict. So I could make my car look like Yanagida's (the pictures you posted) and get it street legal. Would you be willing to assist me in making a 'shopping list', locating the parts I need, and in general share your knowledge of these Nissan works racers?

Kind regards

Emil

i agree that someone should put together a book.... man, what a read that would be....

I'd buy it. Hey Alan got some spare time? Alan I am also curious about the avatar pic you have.

[HS30-H]

Emil,

Let's talk about this in PMs and emails.

jmark,

My current avatar image depicts SCCN works driver Moto Kitano crossing the finish line of the "Race De Nippon" event, held on 12th April 1970, in his SCCN works Fairlady Z432-R. He shared the car with fellow SCCN works driver Masahiro Hasemi, and they took pole position and won the race overall as well as their GTS class.

This was the first major race win for the S30-series Z car worldwide, I believe.
