I am one of those people running around with a 1.9 TDI vanagon conversion and is "flybywire". I used a later TDI ALH and was told it would not work. Rather than go into details, if you'd like to ask me some questions, you can email me directly at nospam at bocafed dot org. Even at 50 degrees, the engine cover is notched. It is not a problem for us. We sleep up top and use the back for storage. My guess is the reason no one is doing this type of conversion is because of the time and money to do one correctly. The transmission also needs to be regeared. Someone asked about the Overland/Eurospec conversion. I looked it over on the website and it does look more suited to the do it yourselfer. They don't mess with laying the engine over. They have a fabricated cross bar and hydraulic mounts. These do not appear to be "flybywire" engines, but mechanical. I am also using an air to air intercooler. Others are using air to water intercoolers that require an electric pump auxilary radiator and plumbing. While my Diesel Vanagon is no longer original it is the most awsome vehicle I have ever owned or driven.
