I've got a '77 240D with just over 500,000 miles
The motor finally puked and I'm wanting to rebuild it. How can I get more power out of the motor? I understand it's not going to be a rocket, but I don't want to be trampled by these big 200HP idiots that are in a rush to get anywhere, ya know? Also, I understand there was a standard tranny as an option? Would it be worth it to swap one of those in?
