I have a 88 CRX SI with 210,000 miles on it. I am trying to figure out what swap to go to. The cheapest would be the ZC but if I bolt up the motor, what about the tranny and axels? do they all bolt up? With the ZC ill have more power, but will I have to get new axels and a better tranny cuz i have tons of miles on it? Plus with the high miles on my car Im wondering if I should just go with a B16a SiR I and change EVERYTHING out. And whats the diference between a 90-93 integra LS motor and a 94-01 LS motor? I eventually want to turbo charge my car so any suggestions would be appreciated. thanks
