  1. "h beams"... One of my favorite interview questions/engineering thought exercises is, "why is it that all connecting rods in modern engines have I-beam cross sections"? As to the topic at hand, I'll be honest and say that this reads like a list of parts that sound "cool" without any further thought behind it. If that's what you want, go for it. But you asked for suggestions on anything you have "wrong". I advise to keep it simple and actually build it rather than slowly melting in a sea of self-created and pointless complexity, eventually resulting in abandonment of the project. Start small.
  2. Hell yes! What did it put down on Rebello's dyno?
  3. William is pricey and will take a while but his work is fantastic. Rob at ZCG sends a lot of his cars through William's.
  4. Congrats Takashi, the Z is finally driving! Drove mine to work last Thursday and Friday. Looking forward to a drive sometime.
  5. Thanks Takashi, I look forward to it!
  6. I have a buddy running 235/50-15 Toyo R888R's on a 15x10. There's a bit of stretch but not a silly amount. The Achilles ATR-K come in a 245/45-15. Both tires are R-compounds, essentially semi-slicks.
  7. I've been driving the Z sparingly due to work and family but I dusted it off this week while I had a couple days off and actually put a wrench on it. I replaced a frozen fan clutch. Yay! I've also been having an issue ever since I swapped out the struts, the rear brakes lock up after parking the car. I transferred the brakes over to the new struts so something happened in that transition. Turns out just the right rear parking brake adjuster keeps adjusting, every time I put the handbrake on. I can yank on the handle multiple times and it just keeps on ratcheting until the brake locks up. I haven't have time to diagnose yet so I've disconnected the right rear clevis for now. Still plenty of things to do but I'll whittle away as time allows. Happy New Year everyone!
  8. If I'm remembering correctly, there was a migration quite a few years back where inactive accounts were erased, or something to that effect. @SuperDan can elaborate, I'm sure. Welcome back to the game.
  9. I'm not familiar with the EFI stuff but where is the PCV valve located on that manifold? Are there any other possible oil paths into the intake that you haven't explored, outside of the stem seal and piston rings?
  10. Sounds like a rich condition more than oil fouling. Can you run the injectors and rail off of the manifold and compare the spray patterns? Vacuum does seem pretty low unless it's a radical cam. I get about 17-18 inHg at idle with a .540"/270° cam. It's all about the overlap and IVC point so you can also have poor vacuum if the cam is too far retarded. Doesn't necessarily explain a fouled plug but worth looking into.
  11. Looking forward to hearing this run!
