Ant you cant say the 4.0 is a piece of shit engine tho, im not saying this just because of the fact that i have one but there are numberous guys on other sites that simply bolt on a powerhouse turbo kit, up the boost to 11 lbs and are running low 12's. SAFELY. i mean if you want a race car you should have bought a GT but to say they will always be slow isnt true. i would boost it before i would shoot juice. the only 4.0's that have blown up are from running boost and juice. there hasnt been one that has blown up from just boost. now im sure if u slapped the PH turbo kit on with 16# of boost then yeah eventually something would go but there are alot of people running 13# and running consistant high 11's.
