A b16 is any car is still fairly rare. Why do you think people bust a nut over a well done 6th gen Civic Si? Same with a del sol Vtec. Honestly, del sols are not a "swap car." (broad generalization) If you buy a car with the intention of a swap, you're noramlly looking for speed. That's why people go with the hatchbacks so often. They're lighter, and have a tighter chassis. Just the nature of the beast. People who buy sols are after the styling, the handing, the comfort, etc. Sols are normally more expensive than hatches of the same condition and year. If you already have a sol, that's when swapping into a sol become the obvious answer. D engines are fine for some. Hell, I've done a few myself. D engines are perfect for most. But when you really want some good power, and don't want to go FI, then a B engine is the way to go. If you're just going for a drag car, then a H engine is the way to go. Most people that want to drag are willing to sacrifice comfort. The people that still want to keep a daily driver stick with D's and B's.
All I'm trying to get across, is that you need to decide what you want out of the car, and then fit an engine, or any other mod to that. If you want to be able to take your granny to the store once a week, you're not going to slam it 4 inches and get rock hard shocks. You'd kill the woman, even though you might look good doing it... Get mah point?
