well, im new to this board.. so hello everyone. now for my question, a friend of mine is swaping out his b16 out his 90 si and is selling me his shell w/ mounts, axles and linkage, after looking around i found a great deal on a b18a1, if i was to pick up the motor would it drop right in with all the parts he left for me? mounts axles and linkage? i would most likely have to get a ecu and harness which should i be looking for? and finally i hear the b18a1 head is not all that great, i have access to a b18b1 head would i be able to swap that on is it even worth it?.. thanks for reading.
