Looking for a crank trigger wheel or crank trigger wheel / pulley combination.
also looking for the crank position sensor holder and crank position sensor.

I don't know if oem Opel 2.0L Jetronic systems use the cps sensor, I'm pretty sure they use the dizzy for that. 2.2's have a weird ignition system. But, I do know that 2.4 Motronic systems use a CPS. They have a round bracket cast into the bottom of the timing cover to hold the sensor. The sensor then reads an external 60-2 tooth timing gear located behind the crank pulley. So, you need a 2.4 timing cover(to the best of my knowledge) and the sensor.
Charles Goin is the guy to ask about getting one of those covers and he can probably tell you how to buy the sensor. I'll send you a "Conversation" message with his phone number.

I've had the toothed pulleys and found them to be really cool and make alternator belt tightening extremely easy. Almost no tension needed on the belt because it can't slip. But the toothed pulley system is extremely noisy and you have to take steps to assure that all 3 toothed pulleys are aligned with each other. That's doable, but a big PIA. Just call Charlie or maybe OGTS has the cover and a sensor they could sell you.

I read that the 60/2 toothed wheel is not good for high rpms using the microsquirt. Not sure but would think it would be the same for the holley system. BUT WHATS HIGH RPMS??
I'll be addressing the trigger mount in the next couple weeks and probably a different trigger wheel also...

It’s not easy to get the timing cover that Gordon is talking about. You’d have to find someone with a 2.4 that wants to use a different timing cover. Not that long ago I considered selling mine. Now I’m not sure. The “what if I go EFI later?” question circles around in my mind. A carb is what I want for the car though, so I don’t need to run a 2.4 cover.

Remember this is upside down. So the Hall effect sensor would be pointed upwards towards the crank.How about a picture of it so we can see how the sensor was mounted ??
Please
I don’t need the ability to attach a CPS since I’ll be running a carb. Doesn’t hurt to have this on the engine though. But getting one of these timing covers for a 1.9 or 2.0 block would be difficult. Someone would have to part with it from their 2.4 and use a regular timing cover instead. Interestingly, when I had my blocked decked, they took so little off that it didn’t impact the timing cover fitment when they forgot to include it in the machining. So this is still a stock timing cover and I can still use a stock one from a different engine. I’d just have to be persuaded to sell and swap.
I Googled this and the first result pretty much covers it.
60-2 Crank Trigger Wheel Kit DISCONTINUED? Now this makes sense.
I'm making this thread because there needs to be proper disclosure for the people who are wasting entire weekends tuning & troubleshooting a product that is not designed to operate outside of a multitude of conditions. So after going down the rabbit hole and throwing my wallet at my problem...
forums.holley.com
The issue showed up past 6500 RPMs, and likely due to the crank flexing a tad bit. The air gap has to be fine tuned on a CPS so if the trigger wheel moves outside of the detection limits, errors will happen. I don’t think there is a problem with 60-2 trigger wheels here. It’s ultimately due to not having an appropriate harmonic balancer to prevent the crank from flexing.
I doubt there would be issues for most Opelers. Very few go past 6500 RPMs.

Thank you @Autoholic for the picture

If the oil pump cover is a good place for the crankshaft position sensor, seems like I could just TIG weld an aluminum plate with a hole drilled in it to that location. I just got a TIG welder last year and am always looking for fun little projects like that.
For reference, here is a picture of the new oil pump cover available at Opel GT Source for around $30. I tried to rotate them so they are somewhat point in the same direction. So you could imagine the extra aluminum in roughly the 2:00 position.

Still probably better off addressing things now then later.
I don't think it would take much to adapt readily available trigger wheels to the stock crank pully. And just a simple bracket to mount a sensor with a threaded body..
Getting an oem 60/2 pulley and 2.4 timing cover is still possible all though will be getting harder as time goes on. And who wants to go swapping timing covers on their cars?? One thing if your building a new motor, but if your just looking for bolt on FI ?

NO!!!!! you'll warp it!!! just make a bracket that bolts to the oil pump cover using 2 of its mounting bolts and use a treaded body crank sensor...

Sounds like you know how to make things happen! So, 3 questions for you:
1) where would you get the steel Reluctor wheel? I think I have seen them at DIY auto tune for right around $30 in 3 different diameters, one of which was 6 3/4” which would probably be the right size for an Opel GT
2) how would you attach the Reluctor wheel to the pulley? Weld it? Pin it? Bolt it?
3) where would you attach the mounting bracket? I don’t know the internal passages of the engine so would be hesitant to drill and tap and hit one (although I love to drill and tap) —- we were typing at the same time, so you answer this one above .

Me?? I'd probably machine my own. But I did find a 5.75" 36/1 wheel on ebay that should clear the timing cover when mounted behind the crank pulls.
There's 6 rivets holding the crank pulley together I would knock out 3 of them, then indicate the pully and repunch the holes with an endmill accurately.
Then I could turn stepped spacers (like a shoulder bolt but have internal threads? To bolt the trigger wheel on....
Either off the 2 bolts on the oil pump housing. Or the two bolts in front of the timing cover on the left hand side..
I'll have to go back and read how far in advance the missing tooth needs to be read before I venture too deep down the rabbit hole..

If someone really needs a 2.4 timing cover and oil pump, I’d sell it. I’m very interested in EFI but for my GT, it will stay carbureted. I don’t have another timing cover, so that will need to be figured out as part of any deal if I sold it.
Charles might be able to get a 2.4 crank pulley with the trigger wheel. The CPS is pretty standard.

Thank you for the generous offer. I am in contact with Charles and he is going to check his inventory for me to see what he has available.

If only someone had designed an aluminum crankshaft pulley with a ledge to add a CPS wheel. And designed the corresponding CPS wheel. And designed a holder for the CPS that bolts onto the outside of the oil pump cover.
That would be awesome
