Best area to post this to?

Where would be a good place for this link within the forum? A friend has been working on this project and has questions about a tune-up for his (Lotus inspired, Volvo powered, low-cost Lotus 7 replica) custom built car.

in the volvo forum, with the relative car to the engine he has installed.

Actually, the Volvo non-specific forum might be better.
