Been silent for a while about this subject because i was busy building and sending out kits.
That is now done for this year, and i can focus on consolidating and improving the supporting documentation as well as planning for whats happening next year.

First on the documentation list is this TPS video where i show how and what to do to the proposed TB in order to use it for our EFI conversion.
This TB will bolt on and work for the 924NA EFI application as well as for the 924SC EFI application and it will even work for the 931 S1 if you replace the factory rubber connector with a more flexible silicone connector.

Thanks for this. I have been watching what your are doing since I would rather get stuff "sussed out" already from you. Much better idea. Slowly gathering parts for the NA which is the original car in the family and the longest running project. I would rather work on the headers etc. This way things are right and I know it will start right away and go

Finally recorded a quick video showing the process to write the tune to the ECU and to calibrate the TPS sensor. This is the last step the user has to do before the first start of the car.

Happy holidays!
Here is the anniversary video.
Summary:
-SC kit will get a higher boost charger pulley next year (free to the first 5 that buy SC and EFI together)
-EFI kit will also take care of the fuel pump, older kits will be easily updated
-i'm recording and working to improve the documentation for the EFI
-2025 will hopefully only have one build run, starting in February, if you want a kit next year, please align with this schedule, i'm trying this strategy next year in order to at least have some months without two jobs.

I pretty sure I am going to order a kit for my 77NA, just don't know when yet. Hopefully on the sooner side.

The current build list is full, i'm more than half way done with building the kits by now.
I did plan to only do one build run for this year, and i might keep that plan..depending on how many people actually want a kit after the current build is over.

Bad news is that i've jumped from the micro company to a regular company now and i will have to collect and hand over the dreaded VAT/TVA tax from next month or something like that...so this will be a price increase.

Mid year check-in: things have been going well, many cars getting the EFI kit and i'm very happy to see most of them on the road, being enjoyed as the 924 was meant to be enjoyed.
I'm very proud and happy about all this, it would not have been possible without this board and this community where it all started and grew from an idea to a small batch of kits.
Of course Cedric and others have contributed and had a massive impact on the direction of the development.

I'm about to take a well deserved holiday, and i'm about to send the last two supercharger kits today, yes i still make those as well and there are still people getting those.

In the second part of the year, i want to finish my 924 which has been a project for a few years now.
I'll keep making the 924 EFI and SC kits, but i'll focus on finishing and releasing the 928 EFI kit.

Please tell me when you are taking orders for the next batch of 924 EFI kits. Have a 77 I've been needing to make more dependable!

Well, i do have one more EFI kit on stock, but not sure i can send it before 15th of August, as i'm on holiday. I can take your order and even write you an invoice but i wont be able to send you your kit until after 15th of August earliest.

Bit of an update on the 928 EFI kit.
I edited the topic title accordingly now, yes i will eventually do a 911 version as well.
Not sure if i posted about this on this forum or not
Long story short, i moved to the 928, the early cars came with k-jet and i've made an EFI kit for those as well.

Prototype car runs, runs great, i've posted some driving and tests on my Instagram.
Still a bit of polishing on the tune, but all the other aspects work as expected and been holding to the tests that i've put the car trough.
I plan to finalize the documentation for this project within the next 2 months and start accepting pre-orders around the same time when everything is ready for production.
If this is something you're interested in or know somebody that might be interested, dont hesitate to get in contact.
