  1. Call Tilton or Wilwood and they will help you decide
  2. That's a tricky question, because pedal feel and overall performance have lots of different variables. Rotor size, caliper size, pad size, pedal leverage ratio, etc all affect how much pedal effort you need and how well it will perform. With the pedal ratio modded to close to 5:1 with 12.2" rotors, Superlight 1.75 4 pistons and Dynalite 1 3/8 4 pistons and Hawk Black pads and after messing with the balance bar a bit I think my brakes feel pretty good. In fact, if I stuck someone else in the car and didn't tell them, I doubt they would know that it was a manual setup. That said others running 6:1 ratios seem to like bigger masters, more like 1".
  3. Found 3 more on my FB page:
  4. I don't even remember having a photobucket account. Tried to log in, all I had were the wind tunnel test pics in there. I know I had more pics at one time, this is all I could find.

    Sorry to see you go.
  6. Wow. Forgot about those pics. Amazing that something so utilitarian and basic was on a car that won so many national championships. I agree that a cradle is the way to go. I think blueovalz's rear setup integrating the diff mount was a nice idea, but that sort of thing (ideally tubing and not a big AL plate) could be integrated with something like this, so that the cradle which mounts the diff and the LCA mounts is a separate bolt in assembly and attaches to the stock mounts for mustache bar and diff xmember/strap mounting points. TSS Fabrication makes similar products for Subaru rally cars. I think he puts too many bends in his products where he could have straight tubing, but here's an example and a link to some more inspiration. https://www.facebook.com/pg/TSSFAB.US/
  7. I have them posted on my FB page: https://www.facebook.com/Jon.E.Mortensen Don't have a lot of time these days. If you (or someone else) wouldn't mind reposting here I would appreciate it.

    I appreciate the shout out, but I don't have the time anymore.
  9. RIP Joel Soileau

    Sorry to hear this. He had been having some health issues but didn't seem like this kind of thing was imminent. Another loss for the Z community.
  10. 300 ZX Turbo CV shaft disassembly and reassembly

    Why not just disassemble/reassemble? I can't imagine how you could get all the bearings in there and have it "wrong" but should be easy enough to redo it.
  11. TIG welder recommendation

    I guess you'll need to weld aluminum to do intercooler piping. Otherwise, the $400 220V Harbor Freight unit is supposed to be really good value. No, I'm not kidding. Won't do AL though. http://weldingweb.com/showthread.php?563691-New-HF-TIG-stick-machine
  12. L31 street performer build

    The rod length is measured center to center, so the diameter of the journal would be irrelevant. My understanding is that he was welding and grinds the cranks to get more stroke (actually I think now I heard he's having cranks forged). He's also using diesel blocks now from what I understand, which allows more rod length because the deck is taller. There is a limit to how close you can get the pin to the deck, so taller deck, longer stroke and as long a rod and as high a pin height as possible.
  13. L31 street performer build

    I recall about 10 years ago you used to be able to get a whole set of Ross forged for about $500, but you had to know the specs. If you called them and asked for an off the shelf Datsun piston, it was $900 or something like that.
