Aussie power query

[Rogersz]

Most of the magazine articles on the 240z and 260z list the stock

BHP as 151 and 137 respectively but my 74 260z I.D plate list's

162 bhp and so do a few aust 1974\75 motoring magazines.

what hapenned down under, what about N.Z and the U.K

what did you get over there.

Hi Roger,

On release in the UK, the 260Z ( RS30 ) was quoted at 162 BHP ( SAE ) at 5600rpm in all the press releases and sales brochures.

Does this help at all?

Best regards,

This is a common question. Alot has to do with US laws. Apparently there was Gross and Net Horsepower Gross being the total power of the engine with all accessories belts etc.. disconnected. EG: Alternator, Air Con and run in a perfect environment. The other NET is a more reliable and accurate reading of horsepower with all it's components connected etc...

So this may explain the discrepancies.

There's more detail about it at http://www.geocities.com/zgarage2001/z.html

hope this helps.:classic:

I think the Australian 260z didnt have all the pollution controll gear that the american cars did, as our emission laws weren't as tough. Can anyone with a aussie 260z confirm this.

Up to 1972 to only emission requirements were that the engine not be too noisy and not smoke.

[Nigel Mulvey]

Unless I'm very much mistaken, we got the flat top carbs that formed part of the US emission reduction system but that was it.

[Zedrally]

Back in 77 when I brought my first zed, iit came with the lot.

Flat tops [because they couldn't sell them elsewhere], air pump, injectors into exhaust manifold, coasting valves and anything else you could imagine that had no relevance to Australia.

Nuff said.

Thanks guy.s

It looks like just the nth american ones were short on horses. My cars not original it has British SU's but the workshop manual {Aussie} show's flat top's, are the U.K su's

better or worse generally than the hitachi round tops.

Cheers Roger

[Nigel Mulvey]

I have British SU's on my 240 and have no problems. I converted the flat tops on my 2+2 to hitachi round tops and still had some problems.

I don't know whether the British SU's are better or not (although SU is a British company) but everyone seems to respond with great enthusiasm when they see them.

[Mr Camouflage]

I heard the aussie 350Z is rated at 217Kw instead of 206Kw.

[Hawkwind]

.. Yeah.. i'd say the states had lower HP because of pollution control fitted to their exhaust.

It's the same story with the Datsun 2000 Sports like my 69 model.

The Australian models were said to have 150bph where as the States got the 135bhp models.

This difference in Horse power wasn't just due to emmision control. The Aussies got the Twin Solex 44PHH carbies made by Mikuni, whereas the states got the HJG46W carbies made by Hitachi.

Our dato's go harder than your Yankie versions

L24 is just 6 cylinder version of the 4 cyl 2.0 liter U20.

interesting facts: Did you know that the Datsun 2000 sports was the first 5 speed gearbox car made of any Japanese motor vehicle ! AND ! The U20 was the first OHC motor of any japanese engine ! All previous cars had Pushrods.

[Mr Camouflage]

U series engines. What were they in?

I thought the L24 was a 6 cylinder version of the 4 cyl L20 and L18.

[Victor Laury]

The U-20 was only used in the Sports 2000. A rare beast indeed. They only made 14,000 SRL (2000) roadsters. Anyone wonder why my timing components cost me $1,400? Sill, it a beautifull engine that I will continue to pay the cost to hear it sing.
