well my question is simple, what do to i need to do with the factory vaccum lines on my sc400? hopefully some one can post up and tell me, i havent heard many people address this subject. im trying to figure out all the small stuff before i get started on my 1uzfe-T build. to just clarify my thinking with you, being as the stock intake tube which has vaccum lines coming off it cannot be used, as this would be an intercooler pipe now. not sure where or what to do with them.
