I am in need of a new motor. My d16z6 is crapping out on me. I need 2 things from you guys here:

1-- What are some reliable JDM motor sellers/stores/shops?

2-- Is there a site that is dedicated to d16z6 motor parts and builds? I may keep my d16 and work the hell out of it. Just want some help and ideas if I go that route.

Thanks
Spike
