i would say that questions pretty much been answered by dv8's & forevra's dyno's. lots of money to make a 3.5 or 3.2 n/a give you 250+ at the wheels -- so i mean this in a serious-nice way -- it would be more cost efficient to start with a different car if you're looking to get 250-300 at the wheels (this is, from what i've gathered, pretty easy with some bolt on mods to a few other cars you can acquire for $3500-7000). i mean, 3.5 swap with "dv8 & telion" pulley, telion chip, obx headers & full exhaust, type2 IM, blackend damper, custom TB or at least TB bypass, custom fuel pump & injectors, CAI, porting & polishing of all possible components, 3 or 4 angle valve job, good racing rims & tires, some good suspension mods & remove a few items to reduce weight i'm sure you will be plenty happy & will at least be up there with the faster of the 3.5's.
Well . . .I think you may need to make amends with those who dislike you because of your initial arrogance. honestly, personally I don't think they got to know you, sure your young and idealistic but the subtlety of arrogance came during Swifts most disliked moments and you were a quick replacement. But having the chance to get to know you better I know that you are no different than many of us here when we were new (but a little more cocky) lol but hell it keeps things interesting. Take all that with a grain of salt
