alot of v-8 also come with alot of luxury items/parts/functions that also increase the price. Alot if imports wont see that because there is no need to with half the power of a v-8. Also in the end, a real import that is customized to have the power,system , and luxury of a v-8 will come out about even. I will tell you what a very knowledgeable tuner told me here on AF. "if a v-8/v-10,12 decides to tune their car like we do, don't race it. we are talking boosting to make the power of a v-8 and there making the power of a v-8. so what if they boosted? Don't race it." Also it is not the cylinders that make that price. it is the luxury alot of 4 bangers don't have.cause they don't need it.
