Thinking of buying a 98 honda civic ex. The car has a swapped motor, it now has a B18C1 from an Integra GSR and a new transmission from an Integra Type R equipped with LSD. The owner said when he swapped the motor he opted out of a/c and power steering. He hasn't got back to me if he actually has the parts to put in ac and power steering. But i was wondering if he did have the parts how hard is it to install? if he doesnt have the parts what would i need to buy and how much am i lookin at spending?
