So I need to convert my 98 ls motor to obd1. My local junkyard just got in a 91 integra. My question is wether there is a difference between da and dc alternators, injectors, distributor? And if I can run my ls on the da ecu?

 

The difference for the alt,injectors and distributor are there plugs. You can reuse them from your motor now to keep everything plug and play.

No you can not use the 91 ecu in your 98,not without a lot of modding.

 

I'll just hold out and wait for dc parts then. Thanks
