I don't know why it isn't letting me edit my question so I'm adding it here.
One important question that I forgot is that how much will the modification cost?
Thank you.
I'm interested in old cars.
Not necessarily vintage cars but the cars from 70's, 80's and some even 90's.
However, the problem is with their engines. They devour gas like an ogre. Like having a mileage of just 8km/ltr.
I want to know what are some modifications that can be applied to these...
