  1. Here is my 260 at Nelson Ledges Raceway last month.
  2. Start with the obvious. Are you sure your odometer is accurate? Get on a highway and watch the mile markers. Go as far as possible and verify that your odometer agrees with the mile markers. A GPS obviously will work too. What size tires do you run? Have you made any gearing or transmission changes? If that checks out, check the basics of the engine. Get a compression tester and PROPERLY check the compression. It should be even across all 6 cylinders and somewhere north of 150 psi. When you have the spark plugs out, take a look at them. Are they light tan, of black and sooty? A vacuum gauge will also give you an idea how it's running. Pull one of the vacuum hoses off the intake and hook up the gauge. If it doesn't read 18 - 20 inches of Hg at idle, the engine might be getting tired. My 10:1 CR '78 280 gets 23/25, so yes, mid-20's are very possible.
  3. Glad to help. It would have been nice to win his beautiful 311, but I'm just glad the proceeds are going to a good cause. Hope Victor recovers enough to enjoy his other cars.
  4. Wow, awesome build! While a L26 might have the potential for more power than your engine, my car has no money in it and as merely a 38 year old motor with new rings and bearings, We probably make far less HP than it had when new.
  5. Nice time. My crapcan 260Z ran a 2:02 a few years ago, but it had several issues and wouldn't rev past 5k. We found both fuel issues as well as a cracked intake valve seat. I'd guess it could run about a 1:57 now.
  6. Thanks for posting. Were you running the short or long course? What kind of lap times were you turning?
  7. For those with 1st gen Z cars, the manuals are available at http://www.xenons30.com
  8. I got in early and just got my confirmation email. I am ticket #2.
  9. I have 16x7 - 0 Panasports on my '78 with 225/50R16 Hankook RS-2 tires. I think they look great, but I had to trim about 10mm of the flange off the rear fenders to keep them from rubbing and destroying the tires. To fix the rubbing, I pulled the springs and moved the suspension through full travel. I kept trimming until they just barely fit without rubbing at all. You can see the missing rubber on the tire's shoulder where the stock fender chewed away at the tire. You can see the width difference in the flange where I had to trim.
  10. Here are my girls Helga and Schultzie our in the yard today.
  11. My 260Z crapcan at the 24 Hours of LeMons race at Nelson Ledges in 2009.
  12. Ask on zcar.com and classiczcars.com. 4 speeds are a dime a dozen in your area.
  13. Spreader plates are the 1/8" thick plates under each tube to support the load. Too small and the tubes will punch right through the floor in a roll. Ideally, they should be on the floor as well as the vertical wall of the rocker or floor kick-up and they must be welded all the way around to work properly. You might want to use a bolt-on tower brace so you can remove the crossbar if you want to haul anything large.
  14. $400 - $600 should get you what you want. I paid $1200 for a full legal road race cage. More than 1/2 the materials and labor are in the front half. The hoop, backstays, diagonal and harness bar are the easy part. Be sure that the harness bar is the right height. When seated, the shoulder belts need to be between 0 and 15 degrees down to the bar. Also, make sure the spreader plates under the hoop are large enough. Here is my cage. It is for LeMons and ChumpCar, but is also SCCA legal. The best pics I have of the cage are mid-paint job, so ignore the nasty interior.
