I read the first couple of pages and there are a few misleading info about making the hybrid. I'll tell you that it can be as reliable as you make it. I advise you not to rush and be very picky with the parts you use. The stock h23a that's in the wagon accord does not make that much power and you can make a lot more by piecing together a hybrid with the right components.
This should help you out a lot and If I was going to build a hybrid this will be my blueprint.
