yeah I did receive an invoice, and yes I personally suspect some things were missing, eg I didn't see the new smaller battery for instance. But a lot of the stuff was on an exchange basis too, so lets call it $10k + a stuffed rb25 motor including plenum and manifolds + return style intercooler.
I already had the PFC, fuel pump etc.
So $10k covered the forged bottom end build including sump adapter, an exchange skyline head, and chinese plenum/zorst manifold/turbo, and all the fabrication of cooler pipes, pod shield, tune etc. I thought it was time to give china's finest stuff a go and see if it can meet everyday requirements....I am far from convinced that we all need top $$$ stuff from japan for everyday builds.
