  1. Years ago I found a service place that catered to Porsche enthusiasts. I needed a bolt-plate alignment (aot to the typical concentric cone style). I think the cost differential was $25 vs $5 per wheel. Yeah, it was painful, but the car became a dream to drive afterwards. Prior, it acted like the front end was going to explode above 50 mph.
  2. I found them on Greenline Motorsports. I think they said 2-5 months delivery.
  3. If the rack is worn, there'd be excessive right and left motion of the steering wheel with no movement of the wheels. You could compare the amount of movement of the steering wheel while the wheels are straight and also at the right and left locks for a clue as to the extent of wear. If the play is similar at all three locations, the problem may well go to another component - tie rod ends, (or as @dutchzcarguymentioned) differential air pressure, different tire tread patterns, any of the three alignment variables, etc. You mentioned you had a concern with a shop's possible non-understanding of how to properly align the car. How do you know the last shop had a clue?
  4. I believe I've read the DS pistons are rebadged Kamearis. Just checked the price: $1375. I figure as soon as I read off my credit card number to TEP, someone will start selling great cast pistons for $300.
  5. That's why I had asked if they were new. My next question was going to be WHERE DID YOU FIND THEM? I'm in the same boat. Need .50mm over. JE Pistons will sell forged pistons direct to you for about $200 each, and Top End Performance will sell you JE Pistons fully and correctly configured for $1300 a set. You can bore ($200) to 1mm over and get Ross for $900 (IIRC), but they seem to not get much love, while JE's seem to be loved by "all". Finally, you can also get Kameari from Japan for under $900, but not in .50mm over. I've been looking for more than a year and am getting uncomfortably close to being okay with $1300 for a set. My engine has had rods conditioned (shortened), the head has been cut, the block has been decked, it has a performance cam waiting to go in, and I am specing 10.5CR. I figure $100 delta for TEP to guarantee proper configuration is worth it; and by getting JE custom made, it obviates buying Cometic or Kameari head gaskets at $200 to get the CR. This is all a lot of fun. I had budgeted around $200 for cast pistons. 😢
  6. Version 1.0.0


    This is a 'functional' replacement and is not intended to appear as OEM. The part was printed at .20mm using TPU. I designed it using a badly deteriorated sample, so it may need some tuning. The old and new appear to match well - but the new part has not been tested on the vehicle. If you print it and find it could use some tweaks, please let me know and I will dial it in.
  7. Are they new or used (or NIB)?
  8. I was all set to use a sealant as a precautionary measure, then decided to cut open the tank bc of some significant denting in it I couldn't resolve otherwise. Sure glad I did. The pick-up tube has a VERY fine mesh screen inside a baffle that I had never before seen nor heard of. I suspect the sealant would have done a brilliant job of sealing up that screen as well as everything else it is supposed to do. Tank is from early production '76 280
  9. I am repeatedly amazed how many people will share a personal story with me about their experience with a Z. Either they had one or a friend did. And the stories are pretty similar - fast, fun, and way cool.
  10. I also have chased the elusive, speed-sensitive steering wheel shake. The problem came directly from a wheel-balance problem - BUT! it's not as simple as just rebalancing. The problem was the wheel weights were not distributed symmetrically about the imbalance. Since any balancing process will never be absolutely perfect, the slight inaccuracy of this particular balancing effort worked very well up to about 55mph. Above that speed, the car acted as though it would explode. Definitely hit a resonant frequency. If the weights had been selected and applied more carefully (shall we say?), the inaccuracy would have been significantly reduced. In the end, a perfectly acceptable balance was achieved by using bolt-plate balance fixture as oppsed to the typical centered balance fixture. The difference being each wheel is balanced based upon its mounted center.
  11. I call that cycling the connectors. After doing a long sentence in the high tech arena, besides smacking the cheese out of it, cycling the connectors is always the first publicly acknowledged step.
  12. @psdenno's strategy is good advice. I've been where you are a few times and it ALWAYS pays to take a breather. In addition, besides my favorite saying of my daughter, "Never do today what you can put off until tomorrow" 😉, I can add a new one. Thanks @psdenno
  13. So glad you found a solution !
  14. A pic of my three favorite things. Nice!
  15. Good commentary on the razor blades. Having the brand of a good product always helps. The heat gun/razor blade paint removal process beats the hell out of chemical stripper. Along that line, back in '97 my brother the "expert" body man was helping me with my restoration (that went dormant until last year). So last year when I was cutting out a bunch of crappy work I had done back then I found 1/4" of filler in the rear lower quarters. Darn I said, how did that get there? Can you imagine, a 1/4"? Guess who's not helping this time around? 😁
