Good point. At this stage I'd probably focus on the transistor control signal too. If the injectors are firing, the ECU is seeing the distributor signal, so checking for a pulsing signal on the transistor control wire while cranking should help narrow it down pretty quickly.

What kind of results have you seen from using R&O oil despite KYB's recommendation? Have you noticed any difference in shock longevity or ease of removal compared to installing them completely dry?

That sounds amazing — especially the idea of seeing a restoration in progress, that must be a rare experience. Are there any other lesser-known places in Japan you’d recommend for classic Nissan enthusiasts, and do you think the Z432-R restoration might ever be something visitors can actually view safely?

I’d honestly just go with good shocks and mild lowering springs for what you want. These cars respond really well to a simple suspension refresh, and full coilovers can end up way too stiff for normal street driving if you’re not tracking the car. Keep the drop mild and focus on ride quality — the car will corner flatter and feel much more planted without losing that classic ZX comfort.

That’s a really serious situation, especially with a head injury like fluid buildup and emergency drilling—those procedures are typically done to relieve pressure in the brain and can be life-saving, but recovery depends on a lot of factors. It’s also completely normal that you haven’t heard back yet; after something like that, he’d likely be in intensive care or heavily sedated, and communicating would not be a priority at all.

For a street-driven ’79 280ZX (S130) aiming for better handling without ruining ride comfort, the consensus from both builders and long-time owners is pretty consistent: If you want improvement without harshness, a quality shock + spring + sway bar setup is usually the sweet spot. Something like Koni/Bilstein dampers with mildly progressive lowering springs keeps the car compliant but removes a lot of the factory float. This is also what many owners recommend as the best “balanced” setup for weekend street use rather than track work. Coilovers, on the other hand, are great when you want full control (height, damping, corner balance), but even “street” coilover kits tend to feel noticeably firmer. On the 280ZX especially, people often report that coilovers can get too stiff on rough roads unless carefully tuned, even if they improve precision and body control. So in simple terms: Best street comfort/performance mix: refreshed shocks + quality springs + upgraded sway bars Best adjustability/precision: coilovers (but expect a firmer ride) If your goal is “less float, better cornering, still comfy,” I’d start with shocks/springs and bushings first. Coilovers make more sense later if you feel limited and want to fine-tune everything.

Totalmente de acuerdo: la IA sirve más como punto de partida que como fuente definitiva. Puede sonar convincente, pero igual hay que verificar todo con fuentes reales. I agree — AI is useful as a starting point, not a final authority. It can sound convincing, but you still need to verify information with reliable sources.

Honestly, I kind of agree with you. AI can be useful, but it’s definitely not something you should blindly trust. It often just pulls information from different sources without really checking how accurate they are. I’ve also seen those AI-generated videos and channels — some of them look very real, but once you pay attention, you can tell something is off. It’s a bit concerning how easy it is to create fake content now. I think AI works best as a starting point, like a tool to quickly find information, but you still need to double-check everything yourself.
