you can use a p13 from a 96 prelude if you can find one. i tried to find one for a long time and couldn't, you can buy a brand new one from honda for about $700, the 96 lude was the only year they made and obd2 p13 without the immobilizer. i am running a p72 from a 96 intrgra gsr and it works but it doesn't run nearly as well as it did when i was obd1 with the jdm p13. also you don't want to get the p73 because it wont control the iab.
