what is the basic solutions for ignition retarding in turbo Motronic 325i engines ? other details (internal components, comp ratio , fuel regulator etc) seem to be easy but I have no idea about ignition. What should we use ? Any aftermarket ignition kits ?

Actually the e30 m20 does have a distributor. Only some specific models of 318 are distributorless.

I use a crane cams ignition box and it does have boost retard... but you don't need any retard with a good intercooler and proper tuning.

Forget the fuel pressure regulator and ignition box. Spend the money on a MegaSquirt and Wideband sensor. Well worth it.

Um...I've never seen an M20 with a distributor...:confused:

Are you serious? Every m20 has a distributor.

It's at the front of the valve cover.

Look at mine... I know it doesn't look much like an m20 anymore.. but it is.

m20's don't have gear driven distributers in the traditional sense... but they still have distributers.

The ignition rotor is mounted directly to the end of the camshaft, and the distributer cap is mounted over it, to the upper timing belt cover which forms the housing.
