thats why i went with the D514A along with that if the 585 gets too hot they go to safe mode. or so I read.

To summarise the way I understand it;

- D514A are powerful and safe, D585s are powerful (guessing probably more than D514A) but can fire early if you run too much dwell, that is, over 4 ms. Firing early "can lead to major engine damage".

- Genuine coils (AC Delco or Delphi) are more powerful than generics.

I'd guess you'd want maximum dwell at maximum torque, because that's when its going to be hardest to ignite the mixture.

D514A cant use the LS2RB/ MojoPerformance

gotta make a different one

Last question I promise... Are you using the www.LS2RB.com coil bracket?
If so, did you have any problems fitting the D514A coil? as I believe that bracket is designed to fit the D585 coil

Thanks mate, I've been in touch with Rick from Mojo Performance and he has informed me that the stock Nissan Dwell setting is around 2.5ms. So I will be fine to run the D585 coil without any risk of premature firing with the standard Power FC settings.

Although you can get a better spark by increasing the dwell slightly, at 2.5ms I will still get better performance than stock or Splitfire coils, so no need to mess with it.

Finally got to install my Mojo Performance GM LS2 Coil RB26 Kit and here is my Dwell Settings. Is my setting too safe?

I switched from Splitfire to LS2 Coils seems like the rev is faster and more responsive

For the love of your engine check the base timing, I did the swap from Splitfires to LS2 truck coils with 3.5ms dwell time and the timing of the coils moved advancing timing by 15deg which lifted the head and made 4 pistons catch the bores, have now gone back to splitfires

So you mean the D585s right? That's some whacky shit. Maybe another reason to stick with the lower power D514a's (assuming the don't do the same thing).

Did you notice any weirdness under 4ms? Maybe this is just the known "D585s go nuts over 4ms dwell" thing.

Yeah D585s, the dwell was set to 3.5ms and at that it advanced timing 15deg, which was tuned around but then they started moving the timing around randomly

I went the D585 because they are COP and much neater conversion then anything else, and now that shit went bad I am finding mine isn't an isolated case and actually becoming a common occurrence with these "smart" coils, info I couldn't find when I researched it before going the setup

It is like they where somehow firing on the rising edge instead off falling edge when they should have been

I am now looking at Audi R8 coils to get the spark I need to run 30psi

    • This is the territory of the "Stage 1/2/3 Golf GTI/R" or otherwise off the shelf tune with (relative to before) minor mods. It's easier now. Downpipe and Tune and boom, big increases. Stage 1 OEM+ is where it's at. This is where the niche evolved into and it's really easy to see why. It's rare to even NEED to consider changing turbos or going to aftermarket ECU's or building bottom ends for more power. Stage 1-2-3 will get you a LONG WAY. Civic Type R turbo GR Yaris/Corolla Anything with B58 (MKV Supra/x40i) Anything BMW in General Anything Audi in General Any turbo AMG RenaultSport Turbo offerings Korean Elantra N/I30N Ecoboost Mustangs Focus RS? List goes on. I would argue in the future it won't even need to go on... M3P is pretty rapid out of the box...
    • There is a way, but it's not with the same cars. You need to find the same vintage of car, that we had. Realistically, that was an affordable car with aftermarket parts around. So what people need to find is a car that had a decent base in its day, and can be modified. They're looking for a car year make of 2010 to 2015 really... Aus could have done it if Holden didn't fold as V8 commodores were cheap, and if Ford didn't get expensive thanks to COVID, then you could cheaply play with FG Barras. Realistically, those are just a bit heavier, four door skylines. I'm sure the US and UK have similar cars they could find.
    • Haha I do that.. thats when it chirps..The bit point for me is almost non-existent. Otherwise I stall it. But yes, in terms of performance, the clutch is solid af.
    • Greg speaks wisdom. These dirty old Datsuns are only value when they are cheap. When they are not cheap, there is no value. Sounds contradictory, but it's true. We are now 20 years past the hey day of modifying cheap 90s JDM cars for small amounts of money. This is a different world. If you are rich and can afford not to care about what is effectively wasting money on an old Datto shitter, then I have no reason to argue against it. But if you are wanting to experience what we all experienced back in 2005 (and I bought my car last century!) then there is no way to do it.
    • Short answer: No. Medium answer: No, because you still need to conjure the things out of thin air to bolt them to a NA to make it a NA+T. Long Answer: No - The things you need to conjure - meaning a turbo, intercooling, manifolds, exhaust, intake/manifold/piping, clutch, injectors, fuel pump, AFM (?), ECU + Wiring (woo, N/A loom fun) have to come from somewhere. You could have many scavenged these things from an OEM car that someone had upgraded from and use some of these. This will be cost prohibitive now, especially so in the USA. You'd probably pay the same for newer, upgraded components that are better than old OEM stuff from 25-30 years ago. None of these big ticket items are re-usable for the N/A car. Why not buy new and upgrade while you're there? The only real consideration is turbo and fuel sizing and determining whether you want to stay within the bounds of the OEM engine or get into rebuild territory. These limits ARE lower with a N/A motor and especially N/A gearbox at the starting point. And if you're gonna upgrade those then you may as well consider having them built to begin with. Because everyone here knows you're never far from that next engine rebuild once you start making the power you want... The cars you see on the internet and SAU etc have been built over decades. If you're really clued in... you would sell your US car to somebody for what you paid for it. You would then scour AU JDM pages or SAU and buy a car like Dose's on this forum with your powerful American Dollar. This will save you so much money in the long term. Importing it could be tricky. Or it might not because USA. I have long said the only reason 90's Japanese stuff took off was because a) Japanese people had Japanese cars so that is what they used b) Australians could import these cars to Australia with very minimal changes and use them on the road here c) Neither country had well-priced access to US or EU Sports Cars. I don't believe the JDM scene would have taken off in Australia at all if we had EU priced EU BMW M offerings, or more especially the AUS V8 Scene would never have existed if we had the multitude of US cars like Camaros, Mustangs, Corvettes at the prices you folks do. After all - Do the math. I would say put a V8 in your R34 and that's the smart way forward. It is. I did it. I know this from my own experience. But at that point there's no reason to simply not buy a C5 or C6? It would be simpler and easier and cheaper and bette-
