i have a 325is im just finished rebuilding it. its in excellent condition always has been. went through the block and head eveything is still in good condition. i bought a second motor to fully build. i was going to go with forged bottom end, and fully built head. should i do that or, my plans for now is turbocharge my motor with a generous turbo for fun until i get the other motor complete. so what what im rambling is since my motor is in good condition should i turbo that with a generous turbo or fully build the second? is it worth it. if i turbo my motor on the stock IS (Maybe a cam. can i excpect 300whp with a good sized turbo and electronics.(and the obvious fuel etc,etc, upgrade for the demands)
