WHy not just get a JDM B20-A. It is the same as your B21- just from japan with low miles on it. it will drop directly in. It will not have the FRM issues that your B21 will have. Your B21 will have issues even if you rebuild it. I know- I've owned 88-91 preludes so I'm talking from experience. try another website specifically for 88-91 preludes.
