first of all, this topic doesn't belong in chat, it belongs in the tech section. i wonder why it hasn't been moved there already. Secondly, both engines are good. And in what way do you mean effecient? both engines have their good and bad points. Pick one and use it. Part of the fun of building up a car is finding out shit for yourself. Now i'm not saying to go into the whole process blindly, but when i mean is learn the basics and whatever else you can and then the rest is purely up to you. that's just my 2 cents.
