I have a del sol that has the jdm d15b vtec motor in it and i want to replace it with either a ls vtec or b20 vtec, but i need to know witch is the better combination, because i have heard that ls and b20 blocks weren't that strong, and i am andting to boost the engine. does anyone know which is better and can get higher horsepower levels?And does anyone have a ls or b20 block for sale?
