oh man, I wish I could. Unfortunately, the realities of medical school/residency have me well occupied and poor.
However, I'd love to get my hands on one of those engines just for the hell of it. This is one of those projects that is more about the accomplishment rather than the cost, at least for the first time it's done.
If I got ahold of one, I would likely use my brother's approach to engine swaps. He's a bit of a gear head and has done all sorts of engine swaps for various reasons, including diesels into gassers. He usually takes one of his vehicles (usually a VW) that he already has registered and just swaps another engine into it in his spare time. No messing with the title, registration, emissions, or other headaches. He's done that for 20 years and has never had a problem with it (VW TDI into other cars, 5.9L Cummins into a Suburban, etc). I'm sure it's illegal, but no one ever looks under the hood if you live in an area without emissions testing.
I'd like to see someone else get hold of one of these motors and show us the build.
