For economy I've installed the SPFI from America. Here is the first start up. My only real issue was a sticky injector But works now. The SPFI off an eA82 wasnt sold in Oz. It has a single point injection throttle body. The conversion was in kit form which is hard to obtain but got it locally from a guy that lost interest.

Cant test ride it yet as am waiting for a new radiator.

The stock ea81 had 74hp, the SC12 draw thru at 5psi had 100hp. The stock EA82 SPFI had 90hp with 9.5:1 CR as opposed to 8.7:1. Will be recoing an engine next year with the higher CR.

Main hurdles were- new high pressure fuel pump, return line to fuel tank, O2 sensor installation in exhaust, ECU mounting, many electrical connections. An online conversion manual helps greatly
