Hey guys I'm thinking of switching from OBD-0 to OBd-1 and wnat to know what I'm going to need besides the harness. I have a '90 Crx if that matters and right now I'm using a PR4 computer and have no sensors either!!

 

Please someone help I need to know how much it's going to cost and also everyting I'm going to need?

 

obd1 distributor, 4 wire 02 sensor, and the ecu preferably a vtec ecu if you are vtec.

 

I have a JDM B16a motor swap so I'll need vtec ecu, next question's is about how much is this going to cost me and is it true that I can pick up 10-15hp by doing this?

 

i dont know about the power gains you will get since you can make either obd0 or obd1 make power its all in tuning. the main reason to go obd1 is if you get a motor swap that is obd1 already and want to put it in your ef. and the parts for obd1 like the distributor is easier to get, since obd0 distributors tend to go out alot. and hondata is crap for obd0
