pipe size is AN6 (about 9.5mm) not sure of the bore of the fuel rails cost about £35 delivered

Discussing this very topic in the wanted section at the moment as I am looking to build my own system as I think the costs for some aeroquip fittings and hose is exessive in the pre built kits. this is currently what i'm working on with my z at the moment as i didn't like the cost of the off the shelf systems I don't think it will cost me more than £100-150 http://www.350z-uk.com/topic/78039-diy-rear-mount/page__st__360#entry1558554

as part of this fuel system upgrade i need to make some custom parts although i have a CNC mill it's not really rigid enough for ally i designed it to cut plastics which it does really well so rather than pay someone to make the parts for me I spent my money else where on this in fact. It arrived today I've already stripped, cleaned and adjusted it just need to convert it to CNC and I should be able to get started making parts after christmas

Damn that's big now i'm really jealous Excellent work

canary yellow 1.3L MK4 Cortina £200 in 1984 and no thats not me in the background this photo's off the Internet (before the sarcasm starts) same hideous car and colour though mine had a bright green interior but it was mine and it's all i could afford.

it's just practice so if you never try you'll never be any good my dad says my welding looks like bird s@!t but he was a welder for 30 yrs

So I made a decision about fuel rails and the design of my fuel return system and the decision is I'm not going to have one. At least that's the plan as long as the pressure regulator will fit where I want it to. in a bid to reduce the complexity of pipework and reduce the heating of fuel in the tank due to the heat picked up by the fuel that is being returned in fuel return systems I'm going with the same design APS used on their twin turbo setup running a vacuum hose back to the regulator mounted directly on top of the fuel bucket this may not give as stable fuel pressure as a fuel return system but fuel pressure will be relative to manifold pressure which is the main reason I'm doing this and the much larger volume in the new fuel rails should help to keep the pressure stable. I'm keeping the original fuel damper where the fuel line comes into the engine bay into a AN6 Y feeding the 2 fuel rails the other end of the fuel rails will be linked via AN6 fittings/pipe to help stabilise the pressure in the rails so to the fuel rails themselves there were lots of choices from cheap to stupid money so I went cheap of course because that was one of my main goals when i started this DIY turbo thread to prove that expensive and branded is not necessarily the best or only way to go,well that and you can do it yourself' but since i don't want my car going up in flames due to a fuel leak I plugged the holes put my old injectors in the rails and pressure tested these I pressurised the rails with my compressor to 8 Bar about 116 psi and put them in a bucket of soapy water and other than one of the injectors letting by absolutely nothing looking inside the rails the threads are all clean and there are no burrs from machining I'm not saying all fuel rails are equal or that all cheap Chinese products are good the main problems i see with these goods are the lack of consistency of the quality i could have bought the same product from another supplier and got crap this time i got lucky

I'm 50 in march so no prizes for me either but i am surprised how many older (my age) Z owners there are, aren't we all supposed to be wearing sandals with socks and driving VOLVO's by now ?

My wife's ACCA qualified and picked up her Degree on the way through and she's going to do her masters next year just for fun but she also has 17+ yrs experience she works with a lot of people who have either the experience or the qualifications but the combination is what earns the big money. she pays more in tax than i earn.

Yea looking at all the potential problems it seemed a wise move especially for the price

I've made another purchase for the fuel return system, a second hand fuel bucket complete as i didn't want to risk damaging mine it only cost me £24 complete it's a bit dirty but other than that perfect i've got it all cleaned and stripped down just need to put my lathe back together so i can make the plug that replaces the pressure regulator doing it this way i should be able to keep my car on the road through a large part of the installation

This is so true and just when you think you know it all something else will come up.

there's a link on the bottom of my post but it's a long read

Mine cost me under £2k but if you cant do it yourself then these are the prices you have to pay

Just a related update for anyone interested http://www.350z-uk.c...20#entry1550070

Ok I've got this pretty much finished now just the tidying up left to do, well that and i might change to a higher resolution display if i can find one at the right price the power supply gave me a few problems the mother board was not happy to run at 14 volts instead of the 12 it was designed for and i couldn't drop in a 12 volt regulator as the supply voltage needs to be higher than 14 volts also the battery voltage sometimes drops to just above 12 volts so the easy option after some experimentation was to put a big diode in the supply to drop the voltage by 0.7 volts as the motherboard seemed happy to run between 11 and 13.5 volts. the motherboard and the display are both fed from the live supply for the turbo oil pumps (if you don't know what I'm talking about have a look it's a long read a bit like war and peace http://www.350z-uk.c...diy-rear-mount/ ) which is controlled by an arduino nano and since i had spare outputs on this device i have altered the code so that when the car is started it turns on a relay which momentarily shorts the terminal for the power switch on the motherboard and when the ignition is turned off it does the same to shut it down before the power supply is turned off by the arduino controller Here's a short vid of the start up and shut down sequence http://vid1364.photo...zpsdz5ctsku.mp4 the fascia I made for the touchscreen has been in and out so many times that I'm probably going to have to re-paint it and the wiring around the motherboard needs tidying but other than that i'm done

Cheers Andy. How I wish I had a nice rich relative that would do that, ...I think a Nismo 370Z would look great parked outside my new house. if I win the lottery i'll sort you out but dont hold your breath on that big win

Happy Birthday buddy maybe some long lost rich relative will buy you another Z

the fascia is fiberglass and filler i just used plaster for the mold I have done some more on this project just not had time for a write up hope to get some more done and post it tomorrow or monday

Nice to see you still around Gareth hope the civic is providing you with some fun

So I'm back with a little update I've been having some problems with boost creep basically this means that the waste gate is too small and the gas still going through the turbo is producing more boost than i want at higher RPM the current waste gate is either 35 or 38 mm cant remember which I was going to go up to 44 mm but i cant be bothered to mess about welding new flanges on only to discover it's still too small so I've gone for 50 mm also I've beenpurchasing the components for my fuel return system but this wont get started until next year the waste gate i might do tomorrow depending on the weather

I completely see your point i'd like to start again myself and i haven't even finished yet

called mine christine after she tried to run me over

a lot of the domestic stuff looks good on paper but at more than a couple of meters you wouldn't recognize your own mother also be aware that the cameras with built in infra red led's are only ok if you keep them clear they seem to attract spiders and you dont notice during the day but when you look at night all you see is a bright spiders web i have 4 cameras out the front of my house and 2 at the back all good quality low light cameras 4 sony 2 jvc with separate infra red illumination , as for dvr's i had a really good one for years but when it went wrong i replaced it with one from ebay for £60 as a temporary measure but it was so good i've kept it but the unbranded / re branded stuff from ebay is a bit hit and miss.
