Koryu Posted January 6, 2014 Share Posted January 6, 2014 I have searched and researched this and the census is to replace the 81 l28et crank mounted setup for the 82/83. I will be installing a ms3 with ford cop with bryan blakes bracket. Can I use the crank mounted sensor with ms to fire the coil packs? Or is the 82/83 distributor with diy trigger wheel a better option? I want reliable and performance with the clean look of the coil on plug set up. This is for a 400 hp turbo setup.

randy 77zt Posted January 6, 2014 Share Posted January 6, 2014 http://forums.hybridz.org/topic/77233-30-1-tooth-wheel-with-cherry-hall-effect-sensor/ The easiest cheap way to do this.The sensor in an industrial hall effect sensor and is easy to mount.I had old ms1 so I used 6 chevy lsx coils running in waste spark mode-the ms1 didnt have enough outputs for a full sequential system.The edis is old school stuff and there are easier ways to do this with modern parts.If you want to test your trigger wheel set up the ms will drive the stock zxt coil/ignitor thru the small yellow wire at the ignitor.If you want to run a full sequential efi system you can convert the 81zxt distributor into the cam angle sensor with a small magnet and a vr type sensor mounted into the 81zxt dizzy.The edis coils throw a good spark but you need 3 power transistors to drive the coil pack.My goal was to run the least amount of parts with everything made at home.

evildky Posted January 6, 2014 Share Posted January 6, 2014 If I were you I'd keep the 81 trigger wheel and add an aftermarket sensor, ditch the distributor and run the coil packs. The problem with the 81 is that the sensor and ecu are rare and unobtainable should something fail. the problem with the 82-83 is that the distributor is rare and expensive, and if you plan to run a coil pack the distributor portion is redundant.I'm not sure what kind of trigger wheel is on the 81 but chances are it can be used if not it can be replaced by an off the shelf wheel machined to fit. I'm not sure what kind of sensor it had but I know it's rare and it shouldn't be too much work to adapt a standard cheap replacement in it's place.

Koryu Posted January 7, 2014 Author Share Posted January 7, 2014 I would like to keep it crank mounted likeb it is stock and do away with the whole distributor all together. I will take a look at the trigger wheel and research a sensor that is compatible with with the wheel and ms3. Anyone know of any? Seems like my best bet as I have the entire 81 zxt setup.

winstonusmc Posted January 7, 2014 Share Posted January 7, 2014 The hall sensor they sell on DIY Autotune should work fine for the 30-1 configuration on the 81 wheel. I want to run that configuration on my MS3/MS3x, I run Ford COP. I still want to run sequential, so I am looking into an actual cam sensor running off the cam gear, but that is for another thread. Right now, I am using the DIY optical trigger wheel and I think it could be improved upon. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 7, 2014 Author Share Posted January 7, 2014 Winstonusmc I have been following your build and I like all the info you post. Do you like the ford cop?? I wonder if one could modify a rb20 cam gear to run the rb20 cas?? Or maybe a l series gear that could run a cas.. seems doable. I will look into the hall effect sensor from diy, seems like a great option for me. Btw I was in Oki from 2000 to 2006 Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 7, 2014 Author Share Posted January 7, 2014 I was looking today and it seems the stock trigger wheel is a 90 tooth. I'm thinking this may be a better and cleaner install. http://www.ebay.com/itm/Z-Car-Single-Groove-Aluminum-Crank-Pulley-Trigger-wheel-/310246633999?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item483c23f20f Quote Link to comment Share on other sites More sharing options...

Cleaner, maybe. Better? Dubious. All you need is a grinding wheel and a $30 sensor to use the 81 hardware. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 8, 2014 Author Share Posted January 8, 2014 Thanks metro. I like the way you mounted yours in the old cas. That is the same hall effect sensor I was looking at. I was mainly concerned with using an old dampner and getting a new one with a wheel already on it but I take it no problems from yours. Can't wait to set it up.

winstonusmc Posted January 8, 2014 Share Posted January 8, 2014 That trigger wheel you linked too was too expensive for what it is. Yeah, just grind your wheel down. And on your question about the Ford coils, I like them a lot. cheap, clean, and no spark plug wires to deal with. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 8, 2014 Author Share Posted January 8, 2014 Awesome. Solid advice I was looking for. I'm getting my manifold from senza soon and TonyD has me sold on putting a gt35r on as well. Just slowly building it up nice clean and right the first time. It is expensive but I was looking at how clean it looked. But I can clean up the wheel after I grind it and out the hall effect sensor in the hollowed out cas and make it all look new. Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 8, 2014 Share Posted January 8, 2014 (edited) "the problem with the 82-83 is that the distributor is rare and expensive," $258 at Autozone last I checked... Hall Effect Magnets in the flywheel is a durable alternative. Edited January 8, 2014 by Tony D Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 8, 2014 Author Share Posted January 8, 2014 I agree tony about the flywheel, I lay holes out and drill aircraft parts up and assemble according to blueprint everyday but i don't know if I could drill the holes in the flywheel and line the sensor up properly. I guess I could since the engine is on a stand. I only need to drill and set 6 equally spaced magnets in the flywheel and set the hall effect sensor directly over their path with a very small air gap between them? Sounds not to bad but I'm sure there is more to it ie getting the flywheel balanced afterwords. This is more solid than the crank mount i was interested in? I am running distributorless so I'm not wanting to go the 82/83 route. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 8, 2014 Author Share Posted January 8, 2014 I'm sorry I meant lay the magnets out like I'm adding 6 equally spaced, but in fact only adding 5 in a 6-1 configuration. Or any integer of 6.. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 8, 2014 Author Share Posted January 8, 2014 The 81zxt wheel in 30-1 seems reliable enough and as I already have the parts minus the $40 sensor and a little time. I just don't see a real benefit to go the flywheel route. Quote Link to comment Share on other sites More sharing options...
Tony D Posted January 11, 2014 Share Posted January 11, 2014 Drilling holes using a magnetic pickup will do the shame thing...take a look at Dodge 2.2L Turbo Flywheels to see how they did it. Three holes 120 apart should not affect balance but balancing after work is always advisable. I'm preferential to the flywheel as in an accident it's still safe. If your magnetic pickups get hit sensing the flywheel, enough other things broke that you're immobile anyway. Quote Link to comment Share on other sites More sharing options...
Koryu Posted January 11, 2014 Author Share Posted January 11, 2014 Lol yeah!! If it breaks at the flywheel then there won't be any engine or car to worry about anymore and maybe I could finally save some money!!! Or maybe not... Tony that's 360 degrees divided by 3 holes on a 4 cylinder. would it not be divided by 4 holes and only 3 of the 4 are drilled, so the 4th hole(not drilled) would be the trigger? I will look at the 2.2 flywheel. That will be a good visual aid. I thought on a l6 flywheel to make this work I would drill 5 holes at every 60 degrees and leave the 6th blank.
