thanks leonv, I brought up the chart and only get small square boxes does not tell me anything on my pc . I had to download a microsoft program to open it. but nothing really comes up .it shows different dissy model# but no info

years ago I purchased a zx dissy from victory brit. brand new zx dissy #d6k8-22ar says made in japan.without taking it apart to find out advance timming does anybody know what the vaccum advance timming is on these dissy off hand thanks

let me know how the lca work out looks like a nice product. I do not know how much camber you can adjust with the lower control arms ,some I think . because I believe the tie rods will not give to much adjustment ,but a little is better then none.if you need more caster than the adjustment tc rods can give you can stick a few washers inbetween the ubracket and the machined washer provided you will see when you recieved them kurt

tlorber the tc rod will push or pull the lca forward or backwards .I believe you will have more movement with stock rubber bushings than poly bushings. but it does move

right now I have not had a alinement ,but when I purchased my early 260z in 1979 I did not no it was hit in front drivers side! when it was fixed by unknow bodyshop they mounted the tc rod support back a little to far and as a result my steering wheel was always harder to turn at slow speed like backing up and turning the wheel to go forward.the aliment shop in 1997 could not set caster to proper specs . we got as close to spec as we could ,I do not know or remember how far off, but I know it was off a little. back in 1997 I purchased from msa the nissan adjustable front caster adjuster kit .you really do not get that much adjust out it but it helped.the rubber bushing are now shot that came with it. so I decided to put the ttt tension rods on and set them about 1/2" past old measurements and what a difference .I measured the caster center of wheel to wheel and now I have 90.25" center to center.I need to get the car alined to set @ factory or should I increase caster a little?

we are looking at a 40 year old design did it work yes ! but with today tech. new and improved. I changed my caster by extending my tc rods longer and my z now turns much more easy with the steering wheel then before and the car handles alot better

these are much heaver, the stock rods are 9/16" od and the new ones are 3/4" od alot more rod diameter also I needed to be able to adjust .I do not think these will bend

well I installed the ttt adjustable tc rods today for anybody that might be thinking about them . the ride was tighter and more responsive,nice improvement over the stock rods with poly bushings .put about 20 miles on from smooth roads to semi rought roads and the feel in the steering wheel is not any more than the poly bushings these rods are very beefy as compared to the oem crap

I guess for those who need adjustable tc rods you could remove the helm joint from the rod couplings and make adaptors from the rod couplings to the frame mount and use the stock bushings again

thanks for your reply mike. when I purchase the 260z in 1979 I did not notice it was in a small accident and my caster is off about 1-2 degrees on the drivers side. so I purchased a caster adjusting kit from msa auto about 15 years ago and now the rubber bushings are starting to crack and split apart . now these bushings are no longer made so I can not replace them,so I am looking at these tc rods with deep interest. do you or can you tell me is there any feed back in the steering wheel ? I understand you only drove it for about 100 miles thanks kully

has anybody used these tension rods ? and if so can you give a report as to pros and cons. looking to be able to adjust my caster .I only found these so far .there rods bolt up metal to metal on frame support , no bushings used . I do not know if this is bad as far as feed back in steering wheel or does it not make any difference between using a urthane bushings ,or the metal on metal the way these bolt on to frame thanks kully

thats what I did l28 engine and e46 manaflod off of a 1971

my 1974 260z had a clicking relay the would do the same thing . found the relay by cycling the key and had someone feel for the relay that was clicking.then held the key to start position and had someone tap the relay a few times and it started . so bad relay replace or bypass like I did kurt

try to find the relay that is clicking mine was the interlock relay in my 1974 260z . the relay would not pull in all the way . if you find the one that clicks hold the key to start position and have someone tap the relay and see if it starts if it does replace the relay or like mine nla so I by passed it .kurt

my 1974 260z had been jumping around also with turn signals on some times lights etc this was after the 79 dissy upgrade .so I used the msd tach adaptor and no luck . spoke to the tech at msd and he recommended to use a relay and feed the tack directly from battery bingo my tach is dead calm works perfect . might be worth a try to feed it from the battery direct and see if it might be something else causeing the problem kurt

yes I did the swap over from a early 260 8/74 to a e12/80 dissy .the difference is night and day . starts easy and runs better all around . mine was the orignal auto dissy daul pickup where it retards 8 degrees after warm up for emmissions . I also used the msd 6a ingition and blaster coil . car never ran so good .

stephen I do not know if the vaccum delay would come on to hard or very gradual I have never used one . but I should hook up a vaccum gauge to my ported vaccum just to see what it is pulling at let say 2500 rpms.also check my timming advance also at that rpms to see how much it advances.maybe the is something to gain with the vaccum delay I will put that one on my list of fun things to play with. thanks kurt

hi stephen sorry to get back to you a day or 2 late ,as I had long work days. I am not sure if you knew but the 260 setup is replaced with a l28 /f54 block stock with n47 head , 1971 4 bolt su carbs ,e46 intake , jet hot headers,new 1979 e12/80 dissy .I tried the manafold vaccum and the motor seems to idle higher than ported vaccum .I still have the carbon canister in the car and had a bad smell all the time when I hooked the canister up to the manifold vaccum. my 1974 service manual showed the front carb/ ported vaccum hooked up to the carbon canister and with a tee inline to the dissy vaccum advance.so I tried it and the smell is just about gone at idle, and my orignal takeoff had a hestation which is gone all together now . you are right about my hybrid alot of different stuff but the car seems to run its best now . also my timming is set at 15btdc and it seems to idle very smooth now . not quite sure about the vaccum delay if it will work better but if you think so I would sure be willing to give it a try .kurt

I have a 1979 e12/80 dissy running with a e46 manifold .the manafold pulls vaccum all the time and the carb pulls under throttle ( ported vaccum) at idle the ported vaccum hardly pulls any . but under throttle it pulls great I found the ported is best for me when I give it the gas the vaccum advances my timming kurt

well just to let anybody know if they are looking at these tires I put about 20 miles on them and all I can say is very smooth and handle great!!!.I told my wife when I came home it just made my 1974 z ride like a 20 year newer car.tire size I went with is a 205/65/15 speed rated v .I wanted to stay with my other size 215/60/15 but cooper only offered them in a h rated speed. so I stepped up to the 205/65/15 for the v rated. my old tires were dunlap sport a2 with only about 2000 miles on them in the 10 years I owned them.I am so happy with these tires maybe I will start to drive the car more . I hope this helps anybody who might be looking at the coopers cs4.by the way cooper offers a 45 day trial and I got the $40 rebate.so $69 each installed after rebate kurt

I have a early 260z with a L28 motor ,1979 dissy,e46 intake manifold,4 bold su carbs.been reading old posts and my service manual .the vaccum line I have hooked to my vaccum advance on my dissy is from the ported vaccum valve on the front carb. am I supposed to have a tee in that line and run it to the carbon canister where it says dist. vc ? right now I am running the dist. vc line from the carbon canister to manifold vaccum.there is allways a strange smell to this car when not running in my garage .I would like to straighten out the vaccum line if they are not right.thanks kurt

I am looking for the choke cable support bracket that mounts to the valve cover. as I understand the 1974 260z only used this bracket ,it mounts almost in the center from back to front.if anybody has one and not useing it, it would help me. of course I would pay for it also kurt

sblake01 you did not put me on the offence . I have owned this car since 1979 and there is allways something to tinker with. thats why people love z cars. sometimes I put off a problem for a long time as the car sits in my garage and does not get used for a while.then I get the bug to drive it and work on it . the car is fully restored but there is allways upgrades to be done.when I can not fix a problem I put it off for a while to give my head a rest and look for something else to tinker with kurt

beezee the tech had me use my fluke meter and I read the tach output on the msd6a and it was between 2.8 volts and 3.1 volts so that told him the tach output was working fine. then I took the reading on the msd 8920 and the voltage was 14volts it was the violet wire for the tach. so that was working fine. so we spoke a little more about wireing and decided seperate feeds and seperate grounds .it works like a charm.so I guess you know beezee this made my day .but I still need to run a seperate feed as I said I tryed it off of the positive side of the battery.I will pull fuse box and detail it and hook up the seperate feed this week and let you know . the tech thinks the feed for the 8920 was spliced in to close to the msd6a kurt

sblake01 I fixed the interlock seat belt problem 2 weeks ago as another forum member told me which wire to use from the interlock relay .the black with white tracer I connected to the solenoid and it starts perfect .I replyed back to him and thank him.the tach is fixed today as posted in the drivetrane section. but another member yesterday ask me to try and take a voltage reading from the parking light circuit to see if there is a voltage drop, as the parking circuit can have trouble from overload. he thought that could have caused me trouble with the tack.so 35 year old fuse box I would like to put new in but nla so I will detail it .p90a head still on hold kurt
