i have a crx dx and im wanting to put in a b18b but i dono the deal about the obd0 and obd2 but how would i convert my crx to obd2/what is a crx obd0?? or is there a b18b with obd0 and what other things would i have to do to put a b18b in a crx

 

sry didnt mean to poast 2

 

even though its obd2 you are going to want run it obd1. you'll need...

-the engine itself
-trans of your choice (cable trans would be easiest route)
-90-93 non-abs Integra axles
-90-93 integra MANUAL intermediate shaft
-P75 obd1 manual integra ecu
-Rywire obd0-obd1 jumper with subharness
-b-series into EF shift linkages
-Motor mounts
-throttle cable from DA
-DA integra drivers side engine bracket
-DA integra rear transmission bracket, must be from a manual

You will be reusing your stock dx harness, but you will need to do a DPFI to MPFI swap.

You'll also need to make room for the alternator because it will rub the frame. 2 inches below a square shape hole near your alternator is where you want to start pounding away. And also make sure to take the dust rings out of the inside of the knuckles so the axles don't bind up.

 

ok so i need is a conversion plug like ones on ebay for like 50 bucks??

 

forget about ebay...go to rywire.com and go from there if you are thinking about ecu jumpers and other wiring needs.
It just makes everything less frustrating when you are rest assured your wiring is correct.

Obd-1 is definately the best way to go right now if you are running a bseries, therefore convert to mpfi and then convert to obd-1 via rywire or you can go straight to obd-1 which is a little trickier but no sweat.
Good luck either way.
