hi, i have a 92 acura integra with a b18a1 with auto trans. alot of mods and 183k on it and its about to go BOOM... i can get a 94+ b18b with auto trans with 25-35k miles on it for $790 + $159 for shipping. ok i wanna keep my dc sport header and custom powder coated valve cover and a few other things. Will the b18b be a direct bolt in replacement engine for my car??? Also will i be able to reuse my stock axles, motor mounts and ecu & harness from the b18a1???
