i have never had a ls/vtrec or b20/vtec but i have had freinds that have.....its a 50/50 thing. sometimes you do good other times you **** everything up. i have alot of experience with turbo cars though....9 of the 11 cars i have owned were turbo. buy a good turbo kit get tuned and enjoy your car that is faster than a ls/vtec and imho more reliable...that topic will be argued alot in this thread..reliability is a big thing.
