8 Pin CDI Rebuild

I am almost finished with my 76 930 motor and need to sort out ignition. I have looked at the usual suspects that rebuild CDI boxes but many don't support the 8-pin CDI boxes. Does anyone have a recommendation for a trusted vendor to go through my 8-pin CDI? Thanks!

Years ago,
I needed my 76 turbo 8 pin rebuilt and sent it to Zims in Texas
Try Bob Ashlock, on PP.

We can put our modern electronics in your 8 pin case or we have a complete 8 pin replica box.

I used a 6 pin on my 77 930. Eliminate the two wires that go to that condenser looking module attached to the panel, get a 6 pin plug and swap the wires from the 8 pin plug in the correct order.

Those Bosch CDI units are very reliable and rarely if ever fail. Many assume that this CDI has failed because it doesn't buzz
like the 3/6 pin Bosch units. Do a Google search for its part numbers; 0 227 300 002, 0 227 300 003, various rebuilders.
Typically the problems are; a bad 12V power input or a bad distributor signal, both easily checked with a volt/ohm meter.

Avoid using the Bosch silver coils with any CDI units

A 6 pin box wonít drive an early Turbo tacho. Youíll need one of Bobís adapters too.

Check the year of the tacho, probably a later one.

8 pin boxes produce a 400V positive spike to drive the tacho. The tacho on the early Turbo is therefore more like a 69/70 tacho (that was driven direct from the coil). 6 pin boxes are just 12v so will only drive the low voltage ones (as fitted to the later Turbo).

8 pin boxes will drive tachos designed for 12v but I canít imagine it is very good for the tacho!

the Bosch CDI is a 50 year old design with 50 year old components.

A modern CDI is much much better. Even having a soft rev limiter is great plus more spark.

Best day of my life is when I dumped that old Bosch!! My 911 came alive with a good modern unit.

I know you won't agree. Loren
