Need a tooth count. Vehicle Speed sensor calibration underway!
Oh that's amazing! How did I not think of that? (One track mind, that's how...) Thanks for that! Makes it a bit trickier to compute accurately with a worm. I don't think it matters how may turns of the screw the gear is made from, its got to do with the spacing or tooth angle or something too hard to compute or measure. Guess I'll have to do the work and turn a tranny and count tail shaft vs speedo rotations. Not like I don't have a few trannies laying around... Now if I can just remember what color gear I put in my tranny.... white I think.

Finally Taking the Plunge - EFI
Waiting for someone to comment on the distributor cap.... Had problems in three areas. 1. Ignition noise (COP) killing the USB communication with the car running. Solved with better lower noise COP's (Audi R8 coil packs). 2. The fancy onesix Industries distributor replacement that gives you a combo crank and cam angle sensor could not provide a stable signal that HAltech could trigger on reliably. At this moment with very little trouble shooting I'm pretty sure it's a combo of noise and improper reluctor gaps. I've gone to a better system of a Hall sensors and missing tooth wheel on the crank and a single hall sensor in the dizzy to give me cam position. I running full secquential. I didn't like having crank angle on the dizzy shaft anyway. There is play in that there shaft..... 3. My in-ability to tighten fasteners properly. Loose electrical connections especially. SIgh....

Finally Taking the Plunge - EFI
I am a bad boy. Have not updated this thread for far too long. Shame shame. I'm nearing the end of the voyage. It has been frought with problems, big surprise, but the car is now running well enough to get it to my friends shop for a dyno tune next week. Plan on taking it to Vancouver for their All Japanese show on the 25th. You'll have to be satisfied with a few pictures for now.

Inner tie rod length?
Glad I had one handy. I'd want 1.5 times the diameter of the threads (M14) engaged for strength as a minimum. 21-22 mm, almost an inch. The threads are M14x1.5 LH and RH. There are vendors that have rod end solutions that might get you some more length. Techno toy tuning comes to mind.

When you're nearly 50, wrinkles are part of the package. Actually they are stock from the faxtory. You will find more if you look.

- Need a tooth count. Vehicle Speed sensor calibration underway!
Side note, is it not interesting, how, given the number of speedo cog tooth counts there are out there for all the various diff ratio's, (yellow, blue, white, etc), that they all mesh properly with a single toothed gear on the transmission output shaft? Crazy how they made that work.... Or are all the different tooth count colored cogs different diameters as well, so the tooth spacing stays the same? The mysteries of the universe never end.- Need a tooth count. Vehicle Speed sensor calibration underway!
Crazy question. In a 4 or 5 speed trans, there is a plastic gear on the output shaft that drives the speedo cog. I need to know the number of teeth on that shaft gear. I've had several trannies apart in the past and recycled more of these shafts that I can remember, but never kept one! Why you ask? I have a electronic vehicle speed sensor on my 5 speed now, attached to the speedo cog output housing, and need to compute it's output frequency vs wheel speed. To get a ballpark number, I need the tooth count on the shaft gear to get the speed vs RPM data to enter into my Haltech tuning software. (I get my MPH from a GPS speedometer) If someone just happens to have a tranny apart and can count, it will save me some time at the dyno. Just to record this, I'm using a very special little dohicky made by a Toyota 4x4 offroad support company that came up with a lovely little low cost custom VSS that plugs directly onto the speedo cog housing of many Toyota's and quite conveniently many early Nissans's as well. Outputs the most perfect little 5v square wave. In case there are any others of you that are crazy enough to go DIY EFI in the future. Picture below.- Where to buy tie rod castle nut
A nylok style nut could also work just fine. As long as the taper of the joint is properly seated, the chances of it coming apart is pretty much 0. Remember how much work it was to get that joint apart. I have about 20 of those stock castle nuts I've saved for some darn reason, but hardly practical to mail you one...- Rear strut gland nut
Regarding how tight or close to "all the way in" the nut has to go, what matters is if the nut contacts the strut body top and locks it in place BEFORE the nut bottoms out. Nothing worse than a loose shock cartridge rattling around and driving you crazy. So as long as most of the threads are engaged, and the cartridge is locked in place, you're good.- 1976 280Z Restoration Project

I think toilet sealing rings are beeswax. Cheap and plentiful. Sorry I had to stoop to a potty reference...- Intake manifold interchangeability.
Careful folks. Consider carefully before changing major EFI components without having any control over the stock ECU to adjust fuel and AFM response curves to match. Larger throttle bodies without other corresponding changes will do little but reduce air velocity into the AFM. That flap that gets pushed around responds to air velocity....- Parts Wanted: 240z/260z Camshaft Oil Sprayer Bar
I have some spray bars available. PM me or send me a note to z240@shaw.ca- Rear Wheel Bearings - Can I Pound on Stub Axle
Should you? No. Have I? of course. thread the nut on all the way. use a piece of hard wood to beat on, use a heavy hammer (2lb min), solid support for the strut. If you can't hit straight and hard, don't do it.- Parts Wanted: Need early 4 speed bell housing from 70-71
I think I have one. Can't check for a few days though. We are gallivanting around the great Canadian plains at the moment.- Ron Tyler (RT) differential mount dimensions
Just a note, the RT mount has a notch in one top corner so the bracket goes around the brake/fuel lines that come close in trans tunnel. T3's mount shows the notch. Also, as long as you don't use a GM poly mount (shown in the pic above) to hang your diff from the RT mount, rather just use a snubber above the diff to "squeeze" the diff nose against the snubber/top of RT mount, and continue to use the stock cross member to mount the diff, drive shaft angles are not altered much over stock. You use one of the Energy suspension generic stepped round snubber thingy's and cut off some of it. The snubber shown above gets cut until about 3 steps are left? The ES one I've used only have 4 steps I think and you leave 2. Which reminds me. I may have a few of these brackets (local made) laying around that I had made a while ago.... Let me know if you need one.- ZCON 2020 Date & Location
A mear 3400 km from here. 5 days 4 hours 7 minutes travel time. Easy Peasy.- Too much gasket sealer on head gasket?
Other than to facilitate cleaner removal, if that's something you do a lot, dry is the correct process. The last thing you want is that goop in the oil holes around those copper sealing rings around the two oil passages, The center one seems to have a large blob really near it. Heavy Danger is the term that comes to mind. Flat head, flat block, and cleanliness are all you need. The gasket does all the work. If you have corroded water passage holes that extend beyond any gasket hole, take care of those the right way, not with goop.- Clutch Slave or Clutch master failure
Since the problem goes away after a bleed and returns after a certain amount of use, I'm thinking it's bad seals in either the slave or master. Time to remove and inspect the bores and seals in both. If they are rebuilds of old castings, expect to find pitted bores.- My weekly rant. Premature Parts Death Plague
If I had a choice of quality parts I'd buy them. I have no idea where to find such things. There are no such stores here or anywhere I know of. There is a Dollar Store on every corner however. They have great cheap paint brushes I can use once to clean parts and toss. My parents still have the same paint brushes they used and cleaned since 1956. I still have their working toaster as well. Me think we are doomed.- My weekly rant. Premature Parts Death Plague
I was just surfing trying to find a replacement pertronix module to see if the cost is crazy or not, and discovered I DO NOT have a Pertronix conversion, it's some other brand. Looks different, no actual markings. My apologies for besmurching Pertronix's fine name here. Pertronix V1 had an issue with them if you left the key on for too long without the car running, it would fry the module. V2 (been out for a long time) has that issue solved. Anyway, I'm running again on a old school E12-80 style dizzy with a GM HEI module and spares....- My weekly rant. Premature Parts Death Plague
Heat is indeed the enemy, perhaps time to invent a heat shield for the back of the dizzy that blocks direct radiant energy from the exhaust manifold. One issue that Pertronix is very vocal about is using a coil with at least 3 ohm resistance. I do have that. With lower ohm coils the trigger current is too high which heats up the module to rapid destruction. Same warnings and issues with the 123 dizzy's. On a whim, I stuck the dead thing back in to test if there is any spark today, in case heat WAS the culprit that may have reversed after cooling down. Nope, it's dead. - Inner tie rod length?
