  1. YES!!! Concours-level detail pays off! Congratulations! Like to see both drag and autocross results with killer rubber

    521 carb problems

    I think you should pull a Saturn one from a junkyard. Get you a pulley, etc. https://ratsun.net/topic/7830-saturn-alternator-how-to-wire-in/
  3. They look like vintage Shelby Mesh mags I had for Z car. Didn't know they existed for 6 lug. But there were a lot of similar knock-offs. Pretty cool looking. https://zcarsource.com/wheel-shelby-mesh-14x7-used
  4. Same with Z car - best results by sealing EVERYTHING in the back. Hatch, spare tire well grommets, antenna, etc. Hatch and tail lights were big leak spots - new rubber was cure. You can do a smoke test - rig a shop vac to pull air from sealed cabin. Wave cigarette, etc. around rear, monitor test subject in back of wagon for reaction.
  5. Yes, unlimited aero mods possible now! Please remember to keep your receipts...
  6. This. Also, any pics of the surgery? For what it's worth, I installed mklotz's kit on my truck plus a Wilwood manual proportioning valve. None of this NLSV witchcraft, and left rears as drums. Very happy with results and braking is much less an adventure now. Do your research and get a beebani or mklotz kit, some junkyard parts, and new or reman shiny parts. Here I've had the boy load up telephone poles, then headed for steepest downhill!
  7. Yes! Bet the poor file cabinet didn't see that coming :rofl: Was thinking of related race car nicknames. How about 'Rolling Papers'
  8. Between this and the other thread (http://community.ratsun.net/topic/73826-speedometer-5-speed-tranny-swap/ ) I'm more confused. I might be mixing up truck and Z (short and long) transmissions here. Seems like your sleeve is a different length than would expect for 4 speed. Are the pinion gear shafts longer too? Here's sleeve and gear with yellow 16T out of 260Z 4 speed. Looks 0.75" or more shorter than yours. Have 20T red cog from a 4.11 Z (not clear on source) - it fits in this housing fine, but I think it's the wrong sleeve offset for gears to mesh. Don't have the proper 20-23T sleeve for it. Sleeve + gear overall length approx. 3.125", gear and shaft approx. 3.0" by itself.
  9. Never had great luck with Datsun speedo accuracy BUT my franken-521 is pretty good - 4.375 gears, I believe 19T White pinion in a 280Z 5 speed, 225/60R15 tires (25.6"). None of this helps you, other than to say those tires do NOT fit, rub everywhere. :lol: But I do have a red 20T pinion gear out of a 4.11 Z laying around. Not sure I have a housing to match though. Have a 4 speed sitting - I'll check this weekend and PM you re: classified ad.
  10. Sweet! What's the background - why were they checking out the MX520?
  11. :rofl: Sig line material there
  12. Google says Motorsports Auto, the Z Store, sells them.

    New to us 521's

    I for one welcome our new 521 overlords
  14. What is the reason for the fuel cell? Don't think it was mentioned. I know nothing about this. But, I can say if you have ideas of racing anywhere, I've learned that installation of non-OEM fuel cells (and also roll cages and seats/harnesses) jumps you to a much higher level of safety scrutiny. And the details of what you're doing become important and often viewed as a greater safety risk (bubba'd) versus stock (.gov DOT oversight).
  15. Steering idler arm? (ETA - Wayno too fast!) Mine was completely worn. Tie rods too. Helpful if you can have someone else shake, you look at what's moving underneath. Or shake tire from under car yourself.
