Aussie260z

Because the carby floats act as surge tanks, But i take it that the 280z's from the US would have had surge tanks???

So i assume that the 280z EFI'd car had some sort of surge tank mounted externally to the fuel tank, in addition to the Life pump & EFI pump...........then had all the pollution gear including the 'vapor-liquid seperator' mounted inside the cabin and charcoal canister in the engine bay, What about the 260z's released in Australia after 1975??? did they also have an external surge tank fitted??? Im converting to an EFI'd engine and i want to know what ive got there on my 1977 260z parts car, Its all going into a 1974 260z,

So no fuel actually ever goes into this expansion tank just fuel vapors??? and it is there because of pollution requirements, If thats the case, what sort of fuel systems did the 280z's have? A lift pump inside the fuel tank and an external EFi pump? Or Did they have a lift pump, surge tank and EFI pump arrangement all external to the fuel tank? & Did the late 260z's supplied to Australia have the same basic equipment as the EFI 280z's, except instead of an EFI rated fuel pump, they just had a carby rated electric fuel pump? Dont suppose its a good idea to use the 'vapor-liquid separtor' as a surge tank and mount it inside the cabin, probably get a few to many fuel vapours

What is an expanision tank?

What about redrilling the 280z hubs to suit a 5by114.3 PCD? on the rotor side and the wheel side??? So i can fit different rotors easier and more common wheels?

This was a hot topic.............. I came across a 1977 260z 2 Seater, when i was stripping it, i got to the fuel tank, and was amazed to find an external fuel pump, i followed its fuel lines and it led to a factory mounted (well it looked very factory) surge tank behind the drivers side rear strut, inside the cabin, Therefore there is mounting bracketry for the external fuel pump and a surge tank that would perfectly fit my 1974 Zed, So if anyone is planning on switching to EFI on a pre 1975 Zed, just grab all the fuel stuff from a 1975 onwards Zed and put it into your car, only thing you would have to change would be the regular Zed external pump to a EFI suitable fuel pump, Im saying pre 1975 & after 1975 because that was when the 280z was released with EFI in the states, so im assuming that is when they made the mods to the external surge tank and fuel pump, but i could be wrong on this.................

Z kid, you sure they are the same nut??? sblake01, I dont know about shipping from the USA? i guess it would be on weight and how long i could wait to get them that would determine the price of sending them (ie..........express air-mail probably wouldnt be cheap), but i bet it would end up being about the same price as if i just went and bought them 2nd hand from a Nissan/Datsun Wrecker locally,

This might work for you, http://www.arizonazcar.com/inject.html "1 inch aluminum throttle body spacer to adapt the LARGER 240SX butterfly onto the 1975-1983 Datsun 280Z, 280ZX stock EFI manifold. Includes the longer bolts required. Can be drilled for additional injector, available in red anodized or plain aluminum $36 each"

Thats the ones, my local nissan bloke said $29/each! Even at $7-8 each its not worth it for me, i just have a spare set floating around with 215/65-14 tyres and lots of tread that i thought id whack on untill i figured out which wheels i was going to go with, But paying $50 odd dollars for wheel nuts, no way!!!

Anyone know where i could get a set of (i think) 280zx wheel nuts in Australia, I have a set of 280zx factory mags - kinda look like a snow-flake from memory, they have a weird nut, they have a mushroom head and sink into the mag............

Also...........Mr Mag in Western Australia usually has a few different mags that will suit the Zed, http://www.mrmag.com.au/

Spoke to ROH wheels today and they can help out aswell, They do all of the below for the Zed, they are 3-piece custom designs and are made to your order, can be done in 4 or 5 spoke, http://www.roh.com.au/asp/product_catalogue.asp ADRENALIN MODULAR CHICANE MILANO MODENA MONACO VENTURO They said the 17" rims for about $540AUD/wheel = $2160AUD, which is pretty good considering its a 3-piece custom wheel

Didnt know you could use the TP Magna Rotors, Thanks for the link mate, I think its the s12w caliper, the s12-8 is the caliper for the non-vented style rotor, or thats what the link says ;-) Ive looked at the Peugeot 505, but just thought id like to use a rotor that was a straight bolt-on, instead of having to mod it (re-drilling for correct PCD and enlargening the centre) whereas the 1984-85 300zx rotor bolts straight-up, but does require that spacer, I asked a few local engineering shops and they said i would be looking at $150-$200 a side for the spacers, which i thought was a bit much, I thought about getting the Peugeot Rotor un-drilled, but you cant get Peugeot 505 Rotors undrilled in Australia, I spoke to DBA and they said that its an imported Rotor and it comes to them drilled, But ill ask them about the Magna TP Rotor

Ive been doing lots of reading and investigation and this is what ive found out so far for wheels that will fit Zeds locally in Australia, or atleast be bought locally in Australia, Ive also included their offsets, BS & wheel weights Performance Wheels Performance Challengers 15" by 7" - 7.75kg (17.05lbs) +8, 108mm 15" by 8" - 8.5kg (18.7lbs) -9, 105mm Performance Superlites 15" by 7" - 8.25kg (18.15lbs) 12+, 112mm 15" by 8" - 9.05kg (19.91lbs) -4, 110mm 16" by 7" - 9.65kg (21.23lbs) 12+, 112mm Performance GP5 16" by 7" - 11.2kg (24.64lbs) 8+, 111m Performance Lotus 16" by 7" - 10.6kg (23.32lbs) 11+, 114 Konig Wheels Konig Rewinds 15" by 7" - 6.05kg (13.32lbs) 0 offset, Panasport Wheels Panasport FS 15" by 7" - 7.6kgs (16.72lbs) -4 to +40 @ $375/each Panasport FS 15" by 8" - 8.0kgs (17.6lbs) -4 to +40 @ $420/each Panasport FS 16" by 7" - 7.8kgs (17.16lbs) 0 to +40 @ $425/each Im not 100% certain about the 15by8" rims listed above, ive not yet been able to confirm whether or not these wheels will fit without mods to the Springs or Guards, Also if you got the Cash, http://www.bozeforged.com/ Spoke to the bloke there and says that they are a 2-piece design and can be custom'd to fit your requirements, but were about $4100a set for 17by7 & $4300 for 17by8, He said the following design's could be custom'd to suit the Zed, Fatal Benton Arrow Big Momma Blade Doons Dude Fang Fusion The Rotor Spinx The Wedge The Wedge 5 Affliction & ZE Forged Toxic Diamond The Flight The Mess

I didnt actually look at the $ sign wheels, they are f#cking hillarious

Curious about the 300zx Brakes & Toyota Calipers front brake upgrade for 240-260z's, I know you have to use a special spacer that sits between the rotor and hub, but......... Does anyone know of companies/people that sell this spacer in Australia?

"Not a chance those are all +40 offsets. You'd be scraping springs for sure" Well thats what the guy told me, i didnt ask there offsets though..........

http://www.tempetyres.com.au Go to 17" Packages and part #'s 7001 7002 7003 7006 Will all fit without any spacers, straight bolt on and drive away, not to sure about what tyres you can fit on though, the bloke i spoke to said you should be able to run 235/45-17's or 225/45-17's without to many clearance issues, Also, www.performancewheels.com.au Lotus & Tempest in the 17" by 7" will fit, but you will not be able to fit any larger than 205/40-17 on the front unless you use spacers - this means the overall running diameter of the tyre/wheel is 596mm - factory its about 628mm There is not much choice out there so i thought i put this down in case anyone was chasing bigger wheels,

I spoke to a local engineer and he said that, If you use a spacer that you bolt onto the hub, Then make a groove in the spacer that the wheel will slot into, This will mean that the force of the wheel will not be upon the 4 lugs - but will be transfered through the spacer and into the hub, This means that the wheel lugs will pretty much just be holding the wheel in place and not taking any of the force, the force is transferred through the spacer and into the hub, Do this with possibly longer wheel studs if there is not enough thread left for the wheel nuts and he said it would be pretty strong, enough to be RTA approved anyway, but this was only for a 10mm spacer though........... Anybody got an opinion???
