    hi i have a 88 hatch and i am puting in a DOHC ZC and everything went well until i started puting on the vacum hoses and found that the hoses to my intake were to small or to big, do i just change all the hose sizes?? some went from my car being biger to on my intake which was smaller hose size???

    -thanks for your time

    Are you sure they're going to the right place? Just look for a vacuum diagram. I did a few ZC swaps and I never had a problem with the lines. Was the car an automatic before?

    Okay, the main lines are a large black hose that goes to the brake booster and it's on the driver's side of the intake manifold, it's the only nipple coming out of the intake that size. And the rest are a smaller size. If you post some pictures or send them to me at elidschultz_bballer@yahoo.com I can tell you where they go. I've worked on 4 different EF cars and have a crx with the DOHC ZC in it right now so I got this.
