Let me start by saying I have been online looking for info about this subject and still kind of confusing to me. Thats why Im opening this thread.
I heard you can use a 2nd gen ignition for an 85GSL-SE.
-The first thing there is 4 different kind of 2gen there is the S4 natural aspirated and the S4 turbocharged, the same with the S5. So which one?

- The second thing, What is it that you swap, the whole thing including coils or just get the 2nd gen ignition and use it in the car like it was a 1st gen one?
- What other parts do I have to replace if i want to swap the ignition?

**For some of you this might sound a simple question it might sound a dumb question. Please remember that some of us are just starting with this. I will appreciate if i get only serious answers. Thanks for the help.

 

all FC's with the CAS run the same coils
( there is some european 1986 NA FC's with a dizzy, no CAS )

there is several methods, though the easiest and most successful method is to make a form of DLI ( direct leading ignition ) from a leading FC twin coil
- using the J109 leading igniter and the FC coil base resister ( bypass the igniter there ) and the leads directly onto the sparkplugs

 

go to the 1st gen technical section, and look at the FAQ section at the top of the page. In there you will find the instructions on this mod.
