Jim,
Are you taking delivery of components directly from ECI? Or, are you having an engine shop build your ECI engine?
I had problems with component deliveries on my engine from ECI due to various suppliers not being able to provide the various components needed. However, I had America's Aircraft Engines build my engine. I worked closely with them through the process. There were some delays I had to face concerning the engine but I did get my engine built in August. I had originally talked with AAE at Sun 'n Fun in April. At that time both they and I were thinking I would be getting my engine by June. It turned out to be August after I talked with AAE and ECI at the ECI booth at Oshkosh before everything fell into place.
If you have not talked with your engine builder you should do so. I know Richard and Steve Fowler at AAE were very beneficial in helping me get everything going on my engine.
Good luck.
