    260z back to life but too rich

    My 260z has been laid up for a few years and I've got it up and running again, ported head and inlet manifold, ported HIF6 SUs exhaust manifold on its way. The problem I have is that I can't weaken the mixture enough without fulling a pipe off to let more air in. Is this just a case of...

    Low cranking speed

    Hi, I overhauled and skimmed my head and got the car running but it needed setting up, timing and carbs etc. Now trying to start it again, the engine turns over too slowly to get it to fire. I have checked over my spare starter motor and all seems well and fitted that. Also I remade the...

    Are all 260z starters the same?

    Got my car out today and had loads of trouble with the starter. It looks like bad connections. I thought I'd do up my spare from a very early 260 but it doesn't seem the same. Are all starter motors the same and can I use this early one on my late 260?

    Fuel mixture and timing confusion

    During the winter I rebuilt my spare head for my 260z and took 40 thou off it. I just got it out today and it is running very badly. The timing was miles too retarded. Nearly 40 degrees. I've reset it to 10 degrees to get it run better. The car has ported SUs, on a ported stock manifold and...

    Anyone rebuilt a zed gearbox at home?

    My 260z box is short of synchromesh. I can drive it if I pause between gears but it takes a bit of the fun out of it. I have a spare box of unknown condition and I'm keen to rebuild it. I thought I'd strip it and see how it looks then rebuild it or shove it on and give it a try Has anyone...

    It won't start after head rebuild!!

    I rebuilt the head on my 260z. 40thou skim and ported head. I left the distributor and cards untouched. Loads of spark and I can smell fuel but it won't start. I get a chuff through the carbs now and then but no real signs of a fire. I turned the distibutor to see it that made a difference. Just...

    Best stock exhaust manifold?

    I've just rebuilt the head on my late 260z. When I came to fit the exhaust manifold one of the holes in the flange to the pipe was broken so I thought I'd look at the exhaust from my early spares car. What a nightmare of design that is! It has great big lugs of casting set into the ports...

    My Cmax rolled away!!

    I have a Ford Cmax company car and it is fitted with a solenoid operated handbrake. You flick a switch and it brings the brakes on. It also puts the handbrake on if you take the key out. On Tuesday morning I set off to work and stopped to post a letter. Left it running and flicked on the...

    Timing chain fitting ?

    I've spent the winter porting my head and overhauling it. I took 1mm off the face and fitted cam tower shims from Mike. Now I've come to refit it and put the cam sprocket back on the cam shaft I don't have enough chain slack to get the sprocket on? I stuck the piece of wood into the chain...

    I'm looking to do some cylinder head work on my 260z. My car is a 1979 reg and I have a spares car that was registered Feb 1974. My 1979 head is an E88 with notches for fuel injection and a square landing around the plug hole. I've read lots of threads about E88 heads but I'm still confused...

    260z valve sizes???

    I have two 260z one for spares which is a very early car and my main car which is a 1979. I've read that E88 heads after 1977 had the bigger valves like the 280. Is this right or are both the engines I have identical?:conf2:

    Back on the road!

    Got my 260z back on the road after a 2 year lay up. Set the carbs up on the bank holiday. I fitted a pair of HIF 6 SUs over the winter to replace the flat tops and ported the carb barrels as David Vizard (legendary mini tuner) describes. Also fitted Hilux brakes with 505 discs. What a...

    Slow Flash

    I am having trouble with the left turn indicator on my 260z. MOT coming up and it needs sorting. Turn right all is well. Turn left and the flashing grinds to a halt always leaving the indicators on. I stripped the switch (I had trouble with this before) and it is fine and the problem still...

    Carb modification limitations

    I'm fitting a pair of HIF6 carbs to my 260z. I've ported them, worked on the butterfly area and tidied up the manifold ports etc. Will I gain any improvement in performance or is the flow bottleneck in the head. I've seen lots of cars with triple webbers and I wondered if these improve...

    Best places to sell zeds.

    I want to sell my 260z because a new restoration project is coming. The "for sale" listing here on the website has had a lot of views but I wondered where else to advertise it. Someone suggested Practical Classics perhaps? Anyone any ideas?
