    Reduce the weight of your Z and get the feel of added HP.......

    S30 Frame Construction

    Factory replacement rails were sold as a one piece item, starting at the radiator support and ending behind the seat mounts. I have one side which was used to develop our 240 rails.

    Difficult time fitting swaybar end links

    Assuming you get the sway bar bushing end bolt to fit, remember that you now have lots of suspension setting options (ride height, toe, camber, caster) you didn't have with the stock set-up. You should include corner balancing to your checklist and don't forget to loosen the end links and then once you're happy with the balance and while the car is still on the scales, tighten the an end link until you see a weight transfer. Back off until it returns to whatever it was before and repeat for the other side.

    OER dripping fuel inside barrels

    What filter(s) are you running? A large (100um) from the tank to the pump and a small (less than 10 um) to the carbs? Float needles get stuck. I have been adding Marvel oil to each fuel jug after the middle carb float stuck closed causing a lean and expensive incident. No issues since.

    5-sp Tranny Detents

    Thanks for great picture! Perfect. My issue was similar. It would pop out of third when I lifted to brake at 7400rpm. My planned solution - put a ball bearing on top of the spring and use washers to position the bolt. Too much tension and you can't get it in gear. Too little and it pops out. A Goldilocks situation.....

    5-sp Tranny Detents

    I am aware of three detents on the sandwich plate. Two on the driver's and one on the top right. Can someone tell me which one is for 3rd gear? The top right one seems to be 1st and second.
  7. Rebello uses N42 heads on his high performance and race engines so, yes, $70 is a good price. Grab things that are still in good shape - glass, trim (in and out), wheels, electrical items, any body parts like fenders or headlight buckets, etc.

    Triple Mikuni thread

    Try a half and half mix of say 93 and 110 and then see if your SUs produce the same gray color.
  9. I am not aware of slotted rotors cracking unlike the cross-drilled ones. Those don't make any sense in regards to cooling as the brake pads block any hot gases whereas the slotted ones allow those gases to escape. I currently run slotted vented rotors on the race car but I had them cryo and REM treated so they aren't stock. A mostly stock Z doesn't need vented, slotted or cross-drilled, just a nice set of pads.

    Every Z owners fantasy.....a working Clock

    I ended up putting a 280 clock with a 240 face plate and bezel in my 72. Keeps time within a minute or less over a full year.
  11. There was a factory Datsun race team in the USA? Who knew?
  12. SW/12 with no slots or holes rotors. Those I had cyro and REM treated.
  13. If you are keeping the drums you can install a prop valve as long as you remove the stock one. You could also consider upgrading your shoe compound (Carbotech is a good source or Porterfield). Not a fan of cross-drilled rotors as the hot gas is trapped by the pads on both sides of the caliper. Slotted rotors solve this issue by having slots longer than the pads themselves. I have run the vented rotors with the S12-W Toyo calipers and drums for nearly 10 years on the 240 race car with good results. I moved to rear discs to get great results (jury is out on that until the car sees a track)

    Restoring the undercarriage.

    I agree that the only way to tell is to remove the flywheel. For all the posts about a main seal leak I wonder how many turn out to be a leak from the oil pan gasket. Wind will push any oil leak towards the tranny so a quick check should include a "smell" test to determine if it is engine or gear oil followed by a tightening of the pan bolts if needed. Wonderful work by the way, just great.

    Restoring the undercarriage.

    Lead based paints, grease and of course gasoline was banned in the ,ate 1970s due to its' real potential to cause serious brain damage, especially in children. Lead pipes in the USA were still allowed into the early 19080s and lead in plumbing solder not banned until 1986. Production of lead itself was a primary concern for people downstream. We found high levels of lead in a public playground sandbox miles from a lead smelter. It can be ingested, inhaled and absorbed into the body. It has been theorized that lead pipes, paint, cosmetics with lead along with cooking pans and plates caused the Romans and later civilizations right up to the 20th Century to not develop into their full potential. It will not make you glow in the dark however. That requires something with a half-life or a biological phosphorescence but jaundice is a pretty good third choice.
