Still working on it, so it's not finished, but I think the tab is in the $10K range right now. I found a lot of ignition issues while getting to the plugs so it should run much better after I'm done. You'd be amazed what a V12 can hide driveability wise.... I don't mind working on it but you have to have a lot of patience. My hands and arms are all scraped up from trying to get to everything too. You have to be like a giraffe to reach over the quarter panels and into the engine compartment. We've ordered most of the parts through a Lamborghini dealer and a lot of it has to be shipped here from Italy. The fuel system is good ole CIS. It's basically setup like two inline sixes.
