cockerstar Posted January 6, 2017 Share Posted January 6, 2017 (edited) I picked up a MS3x unit with wiring harnesses that was previously running a 1JZ in a Supra to convert my L28 over from carbs to EFI. I'm still deep in the learning phase, and am currently searching out all of my options for cam and crank sensors. I want this thread to serve as a list of what I've found. Your input is welcome and appreciated. Crank: 1982-83 280ZXT distributor with DIYautotune wheel Purchase trigger wheel only, $28 Pros: - Provides both crank and cam signals for sequential injection - DIYautotune support and documentation (installation and wiring guide) - Widely available as remanufactured parts (currently ~$200) - Shaft is available new (currently ~$90) as Nissan p/n 15040-P8000, "SPINDLE ASSY-OIL PUMP DRIVE", Lookup code 15040 Cons: - Requires specific oil pump shaft, which requires pulling timing cover/damper oil pump to install - Less accurate at high RPM due to gear lash (is this a valid concern?), but is not of t concern unless gears are significantly worn. - Used units are getting increasingly hard to find Austin Hoke bolt-in kit Development pics Purchase kit without sensor, $215 Purchase sensor, $37.50 Pros: - Crank mounted trigger wheel gives accurate signal throughout RPM range - Well-designed kit with straightforward documentation - Fit and finish look great - Uses commonly used sensor - Includes distributor block off plate Cons: - Must use Euro damper which is getting harder to find (Austin is currently developing a new one for the L24 damper) - Cost Drilling flywheel for hall sensor Purchase hall sensor, $43 Will add example install links Pros: - Cheap - Accurate - Sensor is tucked away nicely Cons: - Requires pulling flywheel to modify - May require balancing flywheel after modification Custom mounting of universal or OEM trigger wheel Purchase universal wheel, $29 Pros: - Can control details of mounting (two threaded holes on front of damper looks easiest, inspired by this post by BRAAP) - Cheap Cons: - Costly in time Top End Performance Trigger Wheel fab Service, $200+http://www.racetep.com/automaker/datsun-z/z-car-triple-sidedraft-weber-carb-and-fuel-injection-conversions.html]Info page, scroll to bottom Pros: - Can send in your current pulley and they will fab a kit for it - Can likely control some details since each one is custom Cons: - Possible wait time? Each looks built to order BJH Dynamics / Robello Racing BJH Datdun/Nissan Trigger Wheels Robello Datsun Parts Page Pros: - Quality looks top notch Cons: - Fits their specific damper ($$$) - Very expensive - Looks like trigger wheel only without a bracket for the sensor Cam: Jeep 4.0 CAS in stock distributor location Installation writeup by jacky4566 Pros: - Simple modification for install - Easy to install/remove - Sensor is cheap and widely available both new, used, and remanufactured Cons: - Uses distributor location, so crank signal must come from another spot I'll continue to update this post with more info as I come across it Edited January 15, 2017 by cockerstar Quote Link to comment Share on other sites More sharing options...
jacky4566 Posted January 6, 2017 Share Posted January 6, 2017 (edited) I made the list! Thanks. FYI Technically you could combine my cam trigger with a flywheel trigger for a "duel wheel no missing teeth". No counterweighting!

madkaw Posted January 6, 2017 Share Posted January 6, 2017 I think if the flywheel was drilled at a machine shop that could make exact depth and degree spacing that you might get away without balancing . Pro: more stable and probably more accurate signal Quote Link to comment Share on other sites More sharing options...
Chickenman Posted January 7, 2017 Share Posted January 7, 2017 (edited) You don't have to pull the Timing Cover when you change the OP spindle shaft. Just remove the oil pump. The spindle shaft will drop down when you remove the pump. Spindle shaft has special splined drive to eliminate slop on Dizzy end. Gear slop is not a big concern if new gears are installed.

cockerstar Posted January 7, 2017 Author Share Posted January 7, 2017 I made the list! Thanks. FYI Technically you could combine my cam trigger with a flywheel trigger for a "duel wheel no missing teeth". No counterweighting! Definitely the case! With your setup some other kind of crank angle sensor is needed. Is there a practicality to having cam angle without crank angle? I think if the flywheel was drilled at a machine shop that could make exact depth and degree spacing that you might get away without balancing . Pro: more stable and probably more accurate signal You're probably right about being able to skip the balancing if it's accurately machined. I'm guessing that it wouldn't be far off with a DIY drilling if you're accurate enough for it to be useful as a trigger. Is a flywheel trigger more accurate than a damper mounted one? I wouldn't think so. You don't have to pull the Timing Cover when you change the OP spindle shaft. Just remove the oil pump. The spindle shaft will drop down when you remove the pump. Spindle shaft has special splined drive to eliminate slop on Dizzy end. Gear slop is not a big concern if new gears are installed. Thanks for the info! I didn't realize it would pull out with the pump. Are new gears available? I've made a few edits to my original post to reflect new info.

Ben280 Posted January 8, 2017 Share Posted January 8, 2017 Thanks for putting this together! Awesome resource for future MSx installs. I've got the Hoke Performance crank trigger kit installed on a Professional Products SFI rated damper (PN: 90055). - install guide from Andrew. In your price breakout, there are also some taps and drill bits needed to install the kit, adds about $20 IRC. Quote Link to comment Share on other sites More sharing options...
cockerstar Posted January 9, 2017 Author Share Posted January 9, 2017 Anyone know of any other options out there that aren't custom? Seems like the ZXT distributor with the DIYautotune wheel is the easy and cheap route. Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted January 9, 2017 Share Posted January 9, 2017 Top End Performance has a trigger wheel and mount. I believe I have an older version and seems to be working well. Very simple. Quote Link to comment Share on other sites More sharing options...
Ben280 Posted January 11, 2017 Share Posted January 11, 2017 BHJ Dynamics/Rebello have some off the shelf versions as well. Quote Link to comment Share on other sites More sharing options...

Chickenman Posted January 15, 2017 Share Posted January 15, 2017 Rock Auto has A1 Cardone remanufactured 1983 Turbo ZX distributors #311003 for $166.79 out right. Does not include Cap and rotor, but these are also available from Rock Auto. I picked up one of these distributors for my Haltech conversion and it seems well made. ( Conversion was only tested due to time an health issues ) Note I did have to do a bit of fine tuning to th CAS trigger setup. Out of the box, the CAS assembly was rubbing on the trigger wheel. Taking it apart I found that a couple of plastic " Nubs " on the bottom of the CAS assembly were preventing it from sitting flush. Five minutes with a file and a careful alignment on re-assembly and it was Golden. I think the issue is because A1-Cardone uses a Maxima CAS assembly instead of the original 280ZXT CAS. The locating nubs are slightly different . I also had to drill out the threaded mounting holes in the Dizzy body. The 280ZXT CAS has non threaded mounting holes and the screws slip though the CAS assembly and thread into the Dizzy body, which is threaded. The Maxima CAS is the opposite, and has the threaded holes in the CAS and the Maxima Dizzy body has un-threaded holes. So the screws go in from the bottom of the Dizzy body and thread into the CAS assembly. As A1-Cardone had it setup, both the Maxima CAS body and the 280ZXT Dizzy body had threaded holes and they just ran the screws down from the top though both sets of threads. Unfortunately this allowed no " wiggle room " for alignment of the CAS to trigger wheel and you got some very slight rubbing. Drilling out the threads from the 280ZXT bodyand inserting the screws from the bottom up allows for slight alignment changes to be made. YMMV.

nmehdikh Posted February 16, 2017 Share Posted February 16, 2017 My car currently has the Ignitor electronic ignition on the distributor. I've read this functions as a hall effect sensor, can it be used as the cam position sensor? Quote Link to comment Share on other sites More sharing options...
zjohnson1 Posted February 17, 2017 Share Posted February 17, 2017 (edited) http://datsunworks.com/page3/page4/ This is what I'm running and it works great. I prefer the look of the hidden wheels or having the teeth at the back of the crank but this is very unobtrusive, install is a breeze, and adjusting for timing took no time at all * I was able to make my stock timing indicator work by just bending to fit Edited February 17, 2017 by zjohnson1 Quote Link to comment Share on other sites More sharing options...
Conedodger Posted June 11, 2017 Share Posted June 11, 2017 FYI, MSA just called me yesterday to tell me they got their shipment of the Performance Industries dampeners and wanted to know if I was still a go. Well ya! Quote Link to comment Share on other sites More sharing options...

Skull_Leader Posted October 30, 2019 Share Posted October 30, 2019 It's been two years. is there anything new? The turbo distributors seem to be extinct, and Hoke seems to be defunct. I have a ZX, and I'm trying to keep my power steering and A/C Quote Link to comment Share on other sites More sharing options...
HuD 91gt Posted October 30, 2019 Share Posted October 30, 2019 Turbo distributors are still available available online. I ordered a turbo distributor shaft from the dealer last summer as well. Quote Link to comment Share on other sites More sharing options...

The turbo distributors seem to be extinct, and Hoke seems to be defunct. I have a ZX, and I'm trying to keep my power steering and A/C AEM's EPM provides precise engine position using dual zero-speed optical sensors, which offers the advantage of immediate signal generation regardless of engine speed. The EPM easily adapts to any positive-drive, half-engine speed device such as a cam or distributor drive, and can be used with any aftermarket engine management system that recognizes a 12-tooth crank 1-tooth cam pattern.

josh37837 Posted October 31, 2019 Share Posted October 31, 2019 (edited) If you want to stick with a bolt in option then OneSix Industries has a bolt in cas that uses the dizzy slot. Its a bit pricey but it does the job. you can watch a video of it used: Edited October 31, 2019 by josh37837 Quote Link to comment Share on other sites More sharing options...
