I'm building a locost, but it will be a while before I can drive it:

That's what got me into LFS. I thought I could get a taste for what it would be like to drive this kind of car.

Now playing LFS interferes with the time I should be building my car!

Lots of people build these kinds of cars (LX4, LX6) from scratch. Search the web for "locost".

You don't need a dry sump on a BEC (bike engined car). They work fine with the stock oil pumps. Here in the states there are lots of sports-racer prototypes using 1-liter motorcycle engines without dry sumps. They race in the SCCA DSR class.

There's no doubt in my mind that somewhere there is a locost with an inline 6 engine.
