How Does 4k Electronic Distributor Timing Advance Lock For Turbo

[jmanrolln]

does any1 know how to lock the distributor mechanical advance on a 4k electronic distributor so that the timing doesnt advance tofar with a turbo?

Zip ties. Drill a locking plate. all sorts of techniques. Google it, there is a fair bit about how to modify your advance curve etc.

The head gasket is the weak link in a boosted K motor....... :hmm: :eatlead:

 

Locking the dizzy and running static timing reduces the compression ratio "at the time of firing".

 

 

Oh and to answer the original question: Pull it apart and you'll see how easy it is to do. Either replace springs with cable ties, or cabel tie the weight slots if it has them. You'll see what I mean. :bash:
