William Hurt Posted December 26, 2009 Report Share Posted December 26, 2009 I'm currently running a Ver 1/2 EJ20G with the corresponding G4 Plug-In ECU and have a refreshed EJ205 that I would like to run with Ver 4 STi heads. I plan on converting to USDM 2002+ coils to get away from the external igniter setup associated with the EJ20G. I will use the EJ20G pulleys (crank, idlers, etc.) on the EJ205 block. Of course I will use the cam pulleys from the Ver 4 STi, but don't know whether my current ECU will support this conversion. In particular, will the cam trigger setting change with the Ver 4 heads/cam gears and can I make that adjustment in the Ver 1/2 G4 to accommodate this? Thanks in advance.

Phil Williams Posted January 11, 2010 Report Share Posted January 11, 2010 Hi William. Version 1 to 6 WRX all trigger in the same way so this shouldn't be an issue. Quote Link to comment Share on other sites More sharing options...
