i know that. i have to get the swap before i go much further in the quest for horse power. thanks for all your replies. on another note, my buddy has a turbo that runs most efficently at about 30lbs. he is curious what the hell kind of motor could take that kind of abuse? i told him he's crazy & he'd need a $20,000 motor just to handel that. would be VERY cool though for top end. who knows maybe he'll sell it. as always any replies are appreciated
