Currently gathering the parts to convert my S2 to EFi. I've gone for a diferent approach though. I've opted to keep my block (Rebuilt not long ago) with a EFi CVH head and the 1.8cvh aux belt pulley with trigger wheel and cps there rather than with the Flywheel.

All I need is to chose the management.....

There's a few options but as said do a search, this has been asked a few times!
