BlownCorona Posted August 6, 2015 Author Share Posted August 6, 2015 I was keen on keeping points for the oldschool factor haha, but I'll either swap to a hall sensor insert for the dizzy or a trigger wheel. Am going to have to seriously think about what direction to go from here. The megasquirt does offer quite a lot and I'm warming to the idea of efi. But I still just love carbs Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted August 9, 2015 Share Posted August 9, 2015 Trigger wheel please. 36-1 . So easy to make and set up. Works so well and then you'll be even more setup to go efi. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 10, 2015 Author Share Posted August 10, 2015 maybe. i was getting acceptable results with contact breaker points, that wernt even set properly. im not really that convinced i want to go efi, even if it is better in every way, its just not in the spirit of the car. i mean hotting up the SOCH 18r wasnt the best option either, but still the option i liked best because it was the right choice for this particular car. when i open the hood and see quad carbs i really enjoy looking at it, but if i opened it and saw efi, even ITBs i would be less excited for some reason. im just sick in the head i guess. still decisions arnt being made hastily now that its back home in a garage again. it can sit there until im really happy with a way forward, that all said, another set of Mikuni BST40s arnt proving easy to come by at a reasonably price. i could buy all the individual replacement parts, but it wouldst be cheap.

kyteler Posted August 10, 2015 Share Posted August 10, 2015 I'm with you on the carb thing but fuck me, points are retarded (deliberate pun), electronic ignition. Every time. Such smooth, much rev. Wow. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted August 10, 2015 Author Share Posted August 10, 2015 I agree, I can get a hall effect module that bolts in place of points that will happily talk to the ecu and should be pretty solid signal wise, just not great resolution, which doesn't seem to be an issue anyway.

Rookie Posted September 22, 2015 Share Posted September 22, 2015 If you are set on keeping the dizzy, I thought this was a super clever way to do the ignition trigger. Yu could keep the dizzy cap if you wanted too. Actually it is just a fucken cool setup. 2 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted September 22, 2015 Author Share Posted September 22, 2015 that is super cool. i really need to keep the dizzy, because its gear also drives the oil pump. but id say theres s 99% chance i will copy that car Quote Link to comment Share on other sites More sharing options...
Rookie Posted September 27, 2015 Share Posted September 27, 2015 Heaps of things use water spark coils, I used wrx coils, they need an igniter which is no big deal, you can get the coils off aliexpress for $40 or so. Evos also use wasted spark, but there isn't any need to get wasted spark coils, as you can just wire up individual coils to fire together. So if you wanted you could use four ls coils. All you have to check is whether that which ever coils you use are logic level or not, and use an igniter as applicable. Basically pick a part/ zebra mission is on the cards.

BlownCorona Posted September 27, 2015 Author Share Posted September 27, 2015 oh sweet thats good to know. will have to do some reading Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted September 27, 2015 Author Share Posted September 27, 2015 any issue with earthing two coils though one BIP373 igniter, or does that component get replaced with the OEM igniter? Quote Link to comment Share on other sites More sharing options...
downtrail Posted September 27, 2015 Share Posted September 27, 2015 You'll need 2 bip373's one to drive each set of coils. spark a and spark b Not sure if you have room but i recently did this for an evo motor that had been rwd'd and couldn't use the dizzy trigger any more. Basically machined the rear of the bottom pulley into 24 teeth and mounted the hall effect sensor in behind it. There is also another hall effect sensor on the cam looking at a single cap screw for the sync pulse as its sequential. 2 Quote Link to comment Share on other sites More sharing options...
Rookie Posted September 27, 2015 Share Posted September 27, 2015 If you use an external igniter or logic level coils you dont need the on board igniters (bip373s) though right? That is a sweet set up though, good job. Seeing he has to keep the dizzy it is probably worth putting the trigger there even though it is slightly less accurate.

BlownCorona Posted September 27, 2015 Author Share Posted September 27, 2015 Yup that's my thinking too rookie, couple that with there not really being anything I can machine or mount to on the front pulls and I really like the trigger hidden in the dizzy. The mitsi setup sure it tidy though Quote Link to comment Share on other sites More sharing options...
downtrail Posted October 11, 2015 Share Posted October 11, 2015 Ditch that ignitor and just add another bip373 to spark b. Or you can use it and ditch the bip373 you already have and use that ignitor bear in mind its probably 20 years old. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 11, 2015 Author Share Posted October 11, 2015 I am having a hard time deciding which option is better. I've read that having the noise of the ignitors inside the ecu isn't great, and It's not that easy to find real estate to mount them inside. But on the other hand they are old as you say, though not hard to get and could be swapped out very easily Quote Link to comment Share on other sites More sharing options...
downtrail Posted October 11, 2015 Share Posted October 11, 2015 both will work fine. Yeah people say that but there's factory ecu's mainly euros bmw etc that have the igniters built into the ecu's no problems as long as there's good grounding. best thing about the bip373 is over current protection is built into them so if you over dwell your coils they'll shut down untill the cool down first.

BlownCorona Posted October 11, 2015 Author Share Posted October 11, 2015 if i did use the Subaru igniter, does anyone know for sure if it will require a logic level input? ive only found a couple places that hint online that it does.

Rookie Posted October 11, 2015 Share Posted October 11, 2015 I would use the Subaru Ignitor, they are cheap and easy to get, and work great, as well as get pesky noise out of your ECU (which isn't designed or shielded properly like oem ones are). And yes they are definitely Logic level, Supply it with your ign out and it will work. Quote Link to comment Share on other sites More sharing options...
