Wow amazing! About bloody time some one updated the "spark plug". Was actually discussing this with my mate a few months back talking about how there really havn't been any proper advancements in spark plugs for decades other than using precious metals as electrodes.

i would be concerned about the battery's ability to handle the laser ignition...

Batteries provide a huge amount of capacitance, so I cant see any obvious problem. What am i missing?

Pfft - diesels have been running without spark plugs for a century. Nothing new here.

how the hell does that compare? diesels have a compression ratio of something like 20:1 to ignite the fuel. try using that kind of compression in a petrol engine.

i have no idea about batteries, that's my problem, i'm looking forward to see what can be done about these laser ignition systems, and would they be relevant to our aging RB engines?

That's exactly what I was wondering. Surely the roll-out of this technology would require serious modification to existing vehicles? Ecu, coilpacks, for a start would probably need a change.

i would reckon its not just supplying a current, but also the timing and such, not sure how electrical signals work, but maybe, there can be a "translator" sort of thing that changes the signal for the sparkplugs to something relevant to the lasers?

Hmmmm sounds cheap lol. It'd need a retune to take full effect of the new technology though.

Lol I guess if they lasted a lifetime though they may pay for themselves (it'll be a while before the new technology becomes that reliable)

i wonder how they'd get around the carbon build up on the lazer lens. unless it closed somehow.

Maybe like a spark plug does now - the laser could burn off any carbon.

Next step to upgrade the tech on an RB would be direct injection since that's a mature technology already. The laser stuff is a while away if it ever gets into production.

I reckon internal combustion has got a fair bit of life left in it. Either ethanol or gas (Australia has shedloads of gas. There's just been a $90 billion 20 year deal signed with China).

In regards to the battery issue...BMW and M-Benz have been pushing for 48Volt sytems for a few years now.

They say they have gone as far as they can using 12 volt

these cars have elec brakes/steering/throttle/suspention & 11ty diffent computers etc

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.

    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
