    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?

    you can use some stuff from the crx like the map sensor and engiene wiring harness you just have to change some of the plugs to acomodate the new engine. as far as the obd conversion goes try to get a jumper harness for your ecu they even have them for the dizzy.

    johnson first of all, start your own thread, but put quite easily, if the car runs fine besides the high idle. get a vacuum cap from your local parts store, they sell them in all sizes in packs of like 4.
