To be honest I don't think there's any good shops that just sell Honda parts or similar. Just the usual supply shops like SCA/Bursons/Autobahn etc, and obviously independent places. There's a few wreckers and stuff but the scene generally isn't as big here as it is on the eastern coast.

If you want parts you're best off ordering what you want. It's not like F&F1 unfortunately, where you can just go into a shop and walk away with a full turbo setup + NOS with Vin.
