  1. This thread: "https://forums.hybridz.org/topic/59086-enginetrans-weights-definitive/" has some excellent information, but also leaves me a bit stumped. It gives 363 lbs for the long-block L24 dressed with intake/exhaust bits. A later post in the same thread gives 589 pounds for a complete L28, transmission and clutch/flywheel parts. Maybe I’m compareing apples to oranges, but are the flywheel/clutch transmission 200+ pounds? A later posting gives 291 pounds for the Datsun L16. Again, maybe apples to oranges, but if a 4-cyliner is 291 pounds, would it be reasonable for a six-cylinder from the same family (50 % larger?) to be only a few pounds more? And finally, in the same thread, the S52 (American version of E36 M3, after the stroke was increased for the 1996 model-year) is reported as weighing 406 pounds for the long-block. Not to impute any of the participants in the above-cited thread, but the spread in weights is, to me, counterintuitive. The inline-6s should (I think) be heavier. Having another data point, now for the S54, would be very welcome comparison with the S52!
  2. Just out of curiosity, have you had a chance to weigh that S54?
  3. Nevertheless, the question remains topical. Of the three links in this thread, two are dead; only the Longchamp link still works. Writing in 2019, it is parlously difficult to find wheels in 114.3 mm 4-lug pattern, with the appropriate backspacing, to fit an S30 Z. Coilovers help, owing to reduce spring-diameter, but only so much... assuming removal/relocation of the spring perch. In other words, the search today, is harder than the search 8 years ago, which in turn, is harder than the search 19 years ago, when this site started. The only popular 4-lug RWD car for wheel-fitment, with good aftermarket support, is the Mazda Miata. It enjoys good aftermarket wheel choices, for light wheels at reasonable prices. But the bolt-pattern is 100mm, not 114.3. In today's market, the "best" option would be something custom, or perhaps with a blank center custom-drilled to accommodate the S30... or alternatively, a 5-lug conversion. And that observation, I humbly submit, merits an update of a 8-year-old thread.
  4. "https://forums.hybridz.org/topic/60536-alignment-settings/" The camber numbers are similar to JohnC's "race" setup. The "street" setup has about half of the camber-angle. Regarding the rear toe... it is not inconceivable that there is a manufacturing-flaw in the McPherson strut housings... that is, in how the hole for the spindle-pin was drilling into the casting. It's a defect on the parts themselves, and not a function of how the suspension is set up. The remedy would be to find another McPherson strut assembly. This problem is, I think, more common on the front-end; I had to go through several junkyard parts to find a matched-pair that was symmetric
  5. Very nice! That's precisely the sort of build-philosophy, of which I'd like to see more. What does it weigh? How far back did you set the firewall? What did you use as a guide, to design the front suspension geometry?
  6. It's a generational thing. Persons who are sufficiently old as to remember when the 240Z first came out, would likely feel more visceral comfort with carbs. Those who weren't yet born when the last OEM carburated car left the assembly-line, would presumably have the opposite proclivity. This reminds me of the adage, that most fuel-flow problems are actually ignition (or other electrical) problems. Jon... not to hijack the thread, or to cause offense, but when did you change your philosophy, to favor the V8? Were you not, for many years, in the inline-6 camp?
  7. I'm confused... on all of your various iterations, the alternator is outboard of the driver's side cylinder head. Why can't the alternator be placed in front of the cylinder head, if necessary with "long"-style water pump, and thereby more tucked-in?
  8. I absolutely detest Facebook. It's an awkward format, evidently aimed at housewives vying to impress each other with the most fluffy cake-batter mix. There's no ready means for an extended discussion that's not sullied with inane comments and sprinkles with graphical objective that are ostensibly decorative, but really are only distracting. And then there's the ads. The idea of combining a camera with a portable telephone remains lost on me. Yes, I have a "smartphone", but it takes putrid-quality pictures. Anything presentable requires a proper SLR, and subsequent editing in Photoshop, on a computer. As a person who sits in front of a computer all day, I find its keyboard and user-interface to be far superior to those of a phone. Thus, it is forums, and not some other medium, that are easiest to use, whether as a mere reader or a contributor.
  9. On the contrary, your initiative forms a sensible and useful basis for updating our perceptions as the ensuing months and years roll by. Of course this site isn't completely "dead", but its volume of activity is a paltry fraction of what it was in 2000-2005. Now a comment on the topic of Facebook supplanting forums for automotive discussions. Recently I relented and joined Facebook, via a placeholder account (not my real name, no personal information). The sole objective was to join automotive discussion groups. While occasionally there's an informative or amusing post, the predominant trend is daft and episodic journalizing of recent events... I went here, I saw that, hey neat, let's collect digital affirmations. The technical questions tend toward the elementary (why won't my car start?). The user-interface seems to be aimed at being colorful and pleasing to the eye, rather than conducive to searching for information, for archiving it, for having any sort of stewardship. In other words, it's a pale and pathetic facsimile of forums.
  10. It sounds like a good strategy would be to first make a list of proposals, from the very mild to the egregiously aggressive, and submit them to a TÜV inspector. That would ultimately bracket the possibilities. Is there some option where you first run your freshly-built car on race-tracks only, then obtain some endorsement of safety and reliability from the track officials, and use that endorsement to solicit approval for usage on public roads? If, as seems to often be the case, it is unlikely to source an S30 Z in decent condition in Germany, and your project becomes part swap/grafting, part rust-abatement, part reconstitution of the interior and the supporting mechanical/electrical systems, and part welding of a new chassis-frame, then perhaps there’s merit in reconsidering your options entirely. One possibility, again depending on what the TÜV people say, is to start with a complete wrecked Tesla, harvesting the front and rear clips, a portion of the battery and the battery control system. You would then build a custom sports-car from scratch, but would register it as a “Tesla”… except that it would be considerably lighter, more compact and therefore sportier. You could also do the opposite, of calling your new creation a “Z”, registering it as a Z, but using only a smattering of Z-sourced components, such as maybe the windshield and windshield frame, the roof, A and C pillars… and making everything else custom. Lastly, you could do the aforementioned for some other car, that’s also a 2-seater sports car, but is more common in Europe, for which components are easier to source. One possibility is an even older car – maybe something from the 1950s? – which might be subjected to less stringent requirements on safety and so forth, and would therefore be easier to register?
  11. Considering how much engineering went into the suspension geometry, the structural design and so forth, it seems to be sensible to swap the entire subframe into the Z, without redoing anything "inside" of the subframe itself... even if this means incongruously-looking wide rear track. BTW, what actually is the difference in rear track width? For a "straight" rear subframe swap, you'd "only" need to engineer hard-points that receive the rear subframe, and connect them to the stock unibody. While it is intellectually satisfying to do this in CAD, then maybe CNC-cut the resulting parts, this seems like a misallocation of resources. Maybe it is better to employ the shadetree method, of first bracing the inner fenders and so forth with temporarily welded-in members, then taking a sawz-all to the stock structure, leaving a gaping hole into which to trial-fit the Tesla components? Also, considering that you're in Germany, how will you get this through your TUEV inspection and so forth? And what is your strategy for mounting the battery packs?
  12. Nicely done! Not to quibble, but race against the Corvette was relatively close. You had, one supposes, an advantage of something like 600 pounds and (unless the Vette was a Z06?) at least 50 hp?
  13. Seriously? THE David Vizard? He's still alive?
  14. That's an ongoing debate, with lots of anecdote but no definitive data. That said, "anecdote" points to ~100 pounds difference in weight between the totally stripped metal tub of an early 240 and a 77-78 280. Perhaps BoulderCharles will have occasion to weigh the stripped-down tub, if he embarks on an ambitious restoration/modification. Back to the topic, this looks like a solid purchase. The Z market has changed over the life of this forum. Back in the year 2000, a good (but not spectacular) condition 280Z could be found for $1500 or so. It would have blemishes, but in many cases only "minimal" rust. Today, from what I've seen, that price-point has risen by a factor of 3 or 4. So, this particular purchase is an excellent deal! I look forward to seeing the progress of the build.
  15. Nice build! Granted that it's too late to presently matter, but have you considered setting the firewall back, to create more room in the engine-bay, and to set the engine even further back? Given the plethora of fabrication-skills that we see on the Forum, I'm surprised that this modification isn't more common.
