91' lude motor specs

[SnoXMX03]

i have a 91 prelude Si 2.0 Please corect me if im wrong but i belive it has a B20 motor. What can i do with this motor. I have another one coming and i need to invest some money into it so its a better daily driver. What is interchangable with this block (heads, cranks, rods,) from other motors and what type?

2.1 liter b21a1 should be what it came with unless it was swapped. to a b20. the only head swap that would be easy would be from a another b20a5 oe b21a1. I have herd that h23 rods work in these motors as for anything else www.preludepower.co can help you.
