So this is confusing me, now. I was told that the japanese B20A with 160hp/130ftlbs is exactly the same as the motor in the 88-91 prelude except for how it sits. Why aren't most of the parts interchangeable? It seems like most simple things like oil parts, gaskets, valves, and stuff like that should be exactly the same. Am I lost, or are they in fact the same parts (and we really have to get them directly from Japan?) I'm so confused. I want to drop a b20a in my 88 LX, because my motor has 280k on it and is hurting. This is going to be expensive... ugh.
thanks ahead of time.
