123 ignition in 1.6 CT Transporter
Posted: 09 Nov 2025, 03:32
Hello all,
I have been researching a 123 ignition for my 1981 single cab Transporter. Its a CT motor and has the stock DVDA distributor and a solex 34 pict 4 Carb. In speaking with a rep at 123 they said the TUNE+-4-R-V-V unit would work with the correct curve. My distributor number is 0237 023 005. I could not find much information about this distributor but the guy at 123 ignition found an advance curve and emailed me the file. I would be happy to send that file to whoever is interested. I am a true novice and learning as I go so I think I can make it work. My only concern is that ill be going from 2 vacuum lines on the distributor to one. Im assuming the 123 electronically does something to make up for the other line to keep the timing correct? I just wonder if the timing would be different. I have read lots about people who switched to the CT and the timing went from 5 degrees ATDC to about 8 - 10 degrees BTDC. I have not read any posts about using a specific curve with the CT on a 123 ignition. If anyone has any advice I would be happy to hear it. Thanks.
