i have a 98 civic and am going to be swapping in a b18b. im having the block machined and rebuilt and all for ls/vtec, but for right now, im going to have a complete b18b with a built high compression block. do i need to convert down to obd 1 since a few of the things im going to be using are obd 1? or can i keep it obd2? what kind of wiring will i need to change if i do convert to obd1? i know im going to have to go obd1 for the ls/vtec anyway. but a head will a built valvetrain is gonna cost a pretty penny, and probably wont get done for a while.

 

anyone? can i run an obd2 ls ecu? or can i just run mine? i dont have a knock sensor, does the obd2 ls have one? just trying to get on the road soon.

 

convert to obd1 and save the headaches of running all those extra sensors and bs

 

oh and you'll need a vtec ecu anyways.
