Hi everyone, I'm hopeing someone can help me. I'm new to the swap thing.I have an 89 crx si. I bought this b18a1 engine (obd1 93 integra) from ebay for a grand. And I got spanked. The water jackets on exhaust side had a major leak. So now that I finally got the head swaped. But here is the problem I'm having. I converted obd0 to 0bd1. But I did not know if I need to use the crx vacuum stuff like purge soleniod and map sensor, like in a b16 swap or use the soleniods and stuff from the integra. Does anyone have a diagram of what to do with this vacuum system?
