I have a d16y8 1.6L Vtec with what appears to be bad bearings, so I need to swap out the engine. Because money is an object and I am new at this it's in my best interest to swap out with another d16y8 vtec, but am having trouble finding a good one. What I have found is a d16y7 block with a d16y8 head or a d16z6 - will either of these work and be easy to install? Will I be downgrading if I get either of these? Please help!
