Hey guys, i recently got myself a jzx100 mark 2 and decides to do minor service on my car. I bought 6 spark plugs from supercheap and happens to me that the 1jzgte vvti is running a called wasted spark ignition system. and i was like wt*... i did a few hour research on the internet goggling every information about it and turn out nothing appreciable. SO my question will be do i need only 3 spark plugs to power the 1jzgte vvti or i still need 6? Cheers

Someone may be able to correct me, but my limited knowledge on Wasted Spark is that basically it would have 3 coils that each fire 2 plugs at the same time?

Exactly.

Wasted spark just means two plugs fire at the same time, one during the compression stroke and one during the exhaust stroke. The one during the exhaust stroke does nothing, hence wasted.

hmm, i really dont mean to be a prick man, but...

if you somehow thought that there might be the slightest possibility of your 6 cyl. engine only needing 3 spark plugs... well lets just say if i were you i'd have someone show you how to do it for your first time that is all...

other wise your next post may be something a little more embarrassing/severe

Thanks,

Trent

thanks mate its just so different with the 1jzgte vvti... have more to learn.

Nah your alright mate, i pull it out slowly today and found 6 plugs, it just so different the coil in 1jzgte vvti... if you have seen them before you know what i said. but cheers anyway for the cautious.

    • Just don't use ChatGPT or any other artificial stupidity for the equivalent of googling. Their demonstrated inability to discriminate reality from hallucination should be enough to make them totally untrusted. LLMs don't know anything and cannot think to even the smallest extent. They are just predictors of the next word, and that should never be confused with capability.
    • I think, given the usage model described in the OP, I'd never ever experience the wonders of the 400kW upgrade. What I really need is boost from 2000rpm and probably no more than 260-270rwkW. But I suspect that the highflow is not actually the turbo for that purpose, so I may in fact need to get a G25 or 30 or something right sized and very spooly. We shall see after it is tuned. I've had to back the boost and boost ramp off to stop the thing from pinging since the highflow went on, so I've been almost living the NA life for 9 months now! Injectors are recently in hand. AFM is in hand. Dyno is fixed. Just need to clear a queue of f**king Supras out of the way (and probably fit my new gearbox). So....some time this year? Lol.
    • For what I gather is a Sunday/summer car....braided is fine. You're not going to be left without a vehicle and you have plenty of time for inspection/maintenance. Oof. I wouldn't use them that way. They can probably handle the temperature** but the internal corrugations means that their flow characteristics are a bit shit. Lots of extra friction and pressure loss. Makes them flow like the next pipe size down. ** They are stainless, and the stainless can usually be at least something like 304L, which is pretty good at higher temperatures (unlike 316L, which I would use for a wrt/corrosive environment, but not a particularly hot environment). But the welding needs to be top notch. And even then, because you usually need at least one cone-seat end on them (because you can twist the hose and do up both ends at the same time unless one of them is a union) they can be prone to coming loose with heat cycles.
    • I don't have the OEM oil feed lines though and the turbo-wraparound line is torn, only has water. My plan is to get replacements for these and just connect a braided line to there. And make sure it's leak free. Hoses like these are also sometimes used to connect external wastegates, so for an EGR I think you're good using them.
    • Alright I understand. The most likely case is probably gonna be that I just keep the OEM unit in the car as long as it works.
