gav240z

Anyone have the piece of loom for a 240z hazard set up and switch? I'd love to put one in my Z it's a somewhat luxury for a Z driver lol. And on the topic of interesting facts I believe the US models came equipped with them.

I'm not 100% certain but I believe that the 2+2 console may be slightly longer and has an astray in the back of it for the rear passengers to smoke. Real healthy huh? Not sure on pricing for a new one but they are certainly easier to obtain than a good condition 240z one. I'd say pay between $200-$250 for a new one. $100 for a good condition second hand one (no cracks).

The fuel mixture nut is at the bottom of the carb. If you look underneath you will see a spring loaded nut that can turn up and down. I think from memory down is richer up is leaner. To tell if you are running rich. Pull the spark plugs if they are black in colour it's running too rich. If it's a really light brown it's too lean. Just right is a nice chocolate brown colour. If the throttle shaft on the SU's is stuffed and needs rebushing you'll never get them (the SU's) to sync up correctly. I learnt the hard way. There are several books out there on tuning SU's look on Amazon.com if you are interested. The SU's you have on your Z appear to be of the British Type. Early 240z Hitachi carbs look slightly different and have an Hitachi symbol on the top of the fuel bowl FWIW. You can also generally tell if your too rich when you jump on the gas and you get a large cloud of continuous black smoke. If your are too lean you will notice it go very flat in the top end. If your car is out of tune it's best to go easy on her until you get it in tune. Your electrical timing could also cause poor fuel consumption. My 240z with an L28 lightened flywheel, mild cam, electronic dizzy & 240z carbs is really quite good on fuel. When I drove up to the 2005 Nationals in Goulburn from Victoria, I drove with Sulio in his then new Ford Falcon Wagon (straight 6 4ltr) he was towing also, but our fuel consumption was fairly close. Albeit the Z did drink a bit more. However not bad for an old Z.

Phil Costello still needs a 240z and is running out of time can anyone help? Do we have any tassie members? Cheers

Sulio I told you that $10 crystal ball from Kmart doesn't work. Besides a Zcar sofa isn't such a bad idea. :wink:

Ok from my understanding it's like this. Questions 1. First of all Twin SU's are great carbs and can perform great on any L-series. The problem begins to become evident when you are getting to higher revs and the engine needs to be able to breathe as much as possible. SU's can be bored out so that the throats are larger and port matched to the intake to allow good flow. However if you have ever looked at high performance machinery you will often see throttle bodies along the side of the motor nicely lined up and often on an almost 45 degree angle. Just like the exhaust system on your car the less bends in the system the less restriction there is. Of course in theory this is great just make everything as straight as possible and no problems. However you also have to take into account air turbulence when it hits items such that stick out like an unmatched manifold this is why port matching is so important. Triple carbs come in a range of sizes depending on the size of your engine and usable rev range. The flexibility that you are given with Triple's is alot greater than with the more simplistic SU's. Triple carbs will give a good power increase but to really benefit from them you need to have a nice lumpy cam and some port / valve work to match. Keep in mind with an engine there is an ideal amount of vacuum. Just like your garden hose when you turn the tap on you get a nice dribble of water provide a certain amount of blockage and it will scream out the end. In an engine it's about finding the right flow balance and back pressure. I'm sure someone will correct me here but this is how I understand it. Questions 2 Why are 240z carbs better than 260z carbs? To put it quite simply the 240z carbs were far more simplified because of no emission controls. The 260z carbs in most cases are in need of desperate rebuild and are almost useless after 30+ years of life. I'm sure they can perform well but the amount of modification and work required to them just to get them to a standard that the 240z ones are already at is simply not worthwhile economically. Many 260z owners have had issues with vapour lock and in general they are considered a less than ideal design. I guess Nissan realised the design flaw and went with EFI on the L28.

Hi guys, I stumbled across this today and had to post it. http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Other-accessories/photos/a-88969398/p-36242094.htm Only $19,000 but hey it is rare and someone in Japan would more than likely buy it I think. Anyone know anything about this engine? I think Errol Smith might, Lurch do you know?

If you are looking to return to original condition I would think it shouldn't harm the cars value to paint the car any original colour for that year. As long as the interior colour and exterior match that of say 1972's available colours it should be fine. What do others think?

Triples are cool they look great along a straight 6 and sound awesome. There just so expensive and that's my main gripe about them. For the extra performance you receive I'm not sure if it's worth it on a street Z. I think your money is much better spent on portwork and a nice agressive camshaft. Especially if your not building a race engine. A light flywheel and recurved distributor and some nice high compression will make soooo much of a difference. As Ash said buying the carbs is only part of the expense then you have tuning and parts if it needs rebuilding. I'm not going to go into comparing what is better because it depends on what you want. An original set of Solex's are sought after because they were a sports option part. I guess it really depends on your budget and what you are wanting to achieve. :wink:

Eiji at www.datsunspirit.com can get them for you. Brand new in chrome or matt black. If you do order a set please let him know Gavin from Viczcar.com referred you. Cheers Gavin.

Hi everyone, I just uploaded the images for the first meeting of 2007. It looks like it was a "great success" in the words of Borat. It's a shame I couldn't have been there, but I'm glad we had such a good turnout. You can view the images by following this link here: http://www.viczcar.com/v-web/gallery/index-7.html Enjoy!

Looks like a good event, wish I knew it was on. In future feel free to let me know of any events or post them up here. I'm always interested in attending classic car related events and seeing other cars and ideas that go on. I have the Unique Cars with the car pictured in the first image. Seems like classic car ownership is often long term especially if you want a result like that .

Hey Evan the alignment tool you mention is used to help you when putting the gearbox back in. Basically it centers the clutch itself so when you are under the car trying to put the box back in you don't go nuts like I did without one. They often include a small plastic one with clutch kits. I would recommend using one especially if your the only person doing the work. Trying to insert a gearbox for over an hour under the car is hard work lol. Trust me!
