Alright, I have a 94 del sol with a stock B16a3, to make a long story short, the short block is in need of a rebuild, but for right now, i was gonna just buy a B16a2 stock short block and use it for right now.

I was wondering if there is modifications I would have to do? Since one is obd1 and the other obd2 I didn't know if I would have to add sensors or what not, would it run off my p30 ecu alright? I am basically looking for a quick replacement, and its hard to find a A3. Any help is appreciated. Thanks

 

is there any additional wires i will need to run or no?

 

Nah, you should be good to go. The head is another story though...
