Firewall forward items
The Firewall forward parts are missing from the kit cost on van's website, though depending how you want to think about it, you could consider it part of engine installation. Depending if you go FP or CS prop, the cost for this ranges from about $4k to $5.5k (I've been pricing this up recently).
One experienced builder once said to me the costs are roughly 1/3rd Structure (Kit), 1/3rd Engine & Prop, and 1/3rd for everything else (interior, avionics etc)
RV-9, Empennage and Wings about done, Fuselage started.
