Requires the 280zx turbo distributor or equivelent, so that is what I am looking for!

Terrapin Z Posted February 7 Share #2 Posted February 7 I saw this on Face Book. $350 seems a bit steep though. 1 Link to comment Share on other sites More sharing options...
ckurtz2 Posted February 7 Author Share #3 Posted February 7 @Terrapin Z I saw some on ebay for like $1000 dollars which is rediculous. I agree even $350 seems steep, especially because that one doesnt look to be in the best condition. Going to check it out now. Thank you! Link to comment Share on other sites More sharing options...

I'm no expert yet.. on that.. but isn't there the option to make it without a distributor, and use 6 induction coils and some sensors for timing? As those old distributors have theire problems after 40-50 years i would go for the "modern" approach! Link to comment Share on other sites More sharing options...
Patcon Posted February 7 Share #5 Posted February 7 Yeah, I was wondering if you could use a degree wheel instead of a turbo dizzy. I would expect it to cost $350 or so. $1000 seems high to me but if you've got the only one, then it's supply and demand... Link to comment Share on other sites More sharing options...
duffymahoney Posted February 7 Share #6 Posted February 7 I think there are a few Datsun guys that just throw silly prices on stuff, and sometimes people pay them. Turbo dizzys are always for sale on Yahoo Japan. Link to comment Share on other sites More sharing options...
ckurtz2 Posted February 7 Author Share #7 Posted February 7 @dutchzcarguy @Patcon . I am very new in teaching myself how DIY fuel injection works, let alone the ignition system. I think you have convinced me to go coil on plug, and sequential injection though. I think the modern approach definitely is the approach, I just don't understand how to do COP without the 280zxet dizzy. Would something like this work?https://protunerz.com/collections/sensors/products/onesix-industries-l-series-crank-sensor-hall-billet-new From my understanding to do sequential injection you need something that can measure cam and crank position, and CAS is the way to do the crank? I think this little dingy is just a distributorless CAS. But then what measures the cam? Trying to get educated. The more I learn the easier and more complex it gets at the same time. @duffymahoney I pulled up the sight. How do I navigate it haha. I am not versed in Japanese lol. 1 Link to comment Share on other sites More sharing options...

Coil on plug means you don't need a turbo dizzy. Turbo dizzy would be traditional spark plug. You can use a turbo dizzy and coil on plug, but there are easier/ cheaper ways to do that. Crank trigger will be better then a cam signal, having both means you can run fully sequential, because the ecu knows exactly what stroke you are on. You don't need fully sequential, I have it, and I don't know if it truly helps or not. Coil on plug and wasted spark means two coils are firing at once, which I don't know if all ecus can handle that? The one six unit is nice, drops in and gives the ecu a lot of info. The milkfab crank trigger would be cheaper/ easier in my mind. My coil bracket (M2 Racing-r35 coils, and protunerz- LS coils) are the two on the market I can think of. Lots of guys fab up coil brackets, audi coils, plasma coils, coil packs etc... I have a crank trigger and jeep cas, so fully sequential. Link to comment Share on other sites More sharing options...
ckurtz2 Posted February 7 Author Share #9 Posted February 7 @duffymahoney That helped me understand things so much better, led me off on a trail or more research, thank you. My biggest question is how does the 280zxet dizzy act as both a crank angle sensor and cam angle sensor. Because it does this, it may be simpler to just do this than to get a crank angle sensor on the harmonic balancer and then a cam angle sensor where the dizzy used to be. However, both options look very simple. I was wondering which Jeep cam angle sensor you used? I can't find a part number for it on other forums. Looks like a solid setup to be honest. How smoothly does ur fully sequential motor run? I think the mega squirt platform can handle wasted spark but I would have to look further into it. I think fully sequential would be kind of fun to do, and definitely more modern than doing batch fire and wasted spark setup. I know lots of cars use the wasted spark and batch fire just fine though. Wondering how many years this mega squirt system would last if done properly. I don't want to deal with any of the pain the OEM injection has put me through with constant maintenance and tuning/fixing. 1 Link to comment Share on other sites More sharing options...
Patcon Posted February 7 Share #10 Posted February 7 I'm not sure fully sequential is beneficial either. It does place less load on ignition components though. I would probably get a crank trigger and run wasted spark and move on. I would probably only visit fully sequential if I had a problem doing that. Some of the vendors might be able to give you more experienced feedback if you reach out to them. They have a vested interest in your success... 2 Link to comment Share on other sites More sharing options...

I don't want to deal with any of the pain the OEM injection has put me through with constant maintenance and tuning/fixing. I was told by Rebello that there wasn't a HP benefit they saw from wasted spark to fully sequential, I honestly did it just because it wasn't hard. Cost me like 90$ for the jeep sensor mod, plus some wiring. A turbo dizzy can't do fully sequential. But can provide the ecu with enough info for wasted spark. I don't exactly know how the onesix unit does fully sequential, but I know it can. So it must provide 2 signals? Cam signal will have more "slop" in it, crank is superior for that. You can also use a flywheel trigger, but that is more rare. If you google or search for the jeep cas sensor mod, you will find info, I think either milkfab or bossa makes it so you can buy it already done. https://milkfab-engineering.com/shop/ols/products/milkfab-lseries-camshaft-position-sensor 2 Link to comment Share on other sites More sharing options...
ckurtz2 Posted February 7 Author Share #12 Posted February 7 @duffymahoney Did you have to use high-impendence injectors for your setup? I am reading online that for fully sequential the injectors need to be high impendence. For batch fired, that isn't needed apparently. Any ideas? I am eventually going to price out the cost of going fully sequential injection and COP, or batch fire and wasted spark. I guess could I do the sequential injection and then wasted spark? Wouldn't see the point I guess. Link to comment Share on other sites More sharing options...
