im wanting to build a 4.0l turboed for a small car for drag racing nothing like outrageous or anything but a head turner. i have been reading up and it seems like the 4.0s are faster 0-60 than 5.0s. so i could save wieght and have more room for turbos and everything else in a small already tight car im just having problem finding performance internal and externalparts for the 4.0l. so i was just wondering about performance parts for the new mustang maybe there is alittle more out there beleive me i know the explorer is alot heavier than the mustang
