  1. I'm building a new house with a high ceiling garage so I can put a lift so I'm about a year out from getting back to this project.
  2. Yes it's correct, I got some from Belmetric https://www.belmetric.com/standard-height-left-c-3_273_1642/nl14x15-left-hand-nut-p-2822.html?zenid=slnpddj6fn4u2v4a7i23evepk1
  3. Looking for a 5th gear set for a 1983 ZX 5 speed, tooth count 26-44 Or a complete 5 speed from any ZX (if you're in the PNW)
  4. 5/8" wheel spacers? 90 ft-lbs is a little high, the FSM for a '76 280Z shows 58 to 65 ft/lbs. Typically a 12mm lug stud can be torqued to 75 ft/lbs. 80 ft/lbs max.
  5. Do a visual inspection of the other studs, you can also feel if they are necked down from overtorque, the diameter will be smaller at the place where they are stretched. If you find some other ones stretched then you have your answer. Visually you may see more space between the stretched threads. The one in the pic almost looks damaged, the break is really jagged. Have you had it in a shop where they took the wheels off for some reason? I've seen techs take a test drive with the lugs loose and it will cause damage. what is your offset and are you running spacers would be the other
  6. Update on this diff in our Chumpcar endurance racer 280Z with the J30A1 swap. Still going strong after six races of 7 and 8 hour duration. Oregon Raceway Park, Sept 2016, Sat 5th, Sun 1st Laguna Seca, Nov 2016, Thur 21st (blown clutch), Fri 1st Sonoma (Infineon), Feb 2017, Sat 3rd, Sun 1st.
  7. Looks like the design is flawed, the material is weak and possible manufacturing problems this piece should be an off the shelf rod end, one on the stronger more expensive end of the range. Probably a 5/8" dia thread at least. It looks like a fabricated piece and it's too long so it has too much leverage. If you use a rod end threaded straight into the end of the arm then it's hard to adjust so it looks like they made this one with opposite threads to ease adjustment. Normally this is done with a opposite threaded sleeve and regular rod end so it doesn't have too much l
  8. Just make sure they are a matched set from the same engine because they are balanced from the factory.
  9. Here's a reman for $243.00 http://www.zcarsource.com/crankshaft-240z-260z-280z-280zx-300zx_8_55202.html they general don't show any wear until after 150K So guessing like $300 to $400 for a new one
  10. Looking for a 5th gear set for a FS5W71B from a ZX, the short tailshaft trans? The 0.745 ratio 5th Broke some teeth and don't want to buy a whole trans.
  11. J-SWAP SUCCESS!!! Week before track day first start up. Huge vacuum leak from the EGR passages, apparently when you flip the lower intake it opens up the passage, had to tap the plenum and put a pipe plug. The EGR will be re routed externally. A bad main EFI relay from the 200K mile parts car kept the fuel pump from running at first. Night before the track day, drove it for the first time, no windshield or hood at 10pm (wearing goggles) (the dash wiring is easier with the windshield out). Only minor problems, a seeping brake line from where they were re-routed and a rad hose seep.
  12. Did a track day at the Ridge Motorsport Park with this diff installed. No more one tire spinning. Consistently faster coming out of the slow tight corners, especially the hairpin. No noise from this thing, didn't even know it was there aside from the lack of any wheel spin. Ran the Redline 75-W-140-NS
  13. They make straps now with a sliding D ring on one end so you can loop the strap around whatever and connect that way
  14. In no particular order S2000 FRS BRZ (w turbo or super charger) Z06 Vette with LS7 R32 Skyline (imported from Canada) Z32 twin turbo
