I have a 90 dx ef and I was thinking about putting in a sohc zc motor, do you think it would be ok if I leave it a 2 injector setup or do I need to rewire it to 4 injectors? Just curious if the motor would run lean, has anyone tried this? Im not looking for preformance just want to get my gas saver running.

 

It'll work fine. Don't expect big gains for a minute increase in capacity though. Most of the extra power comes from the engine having more efficient intake and exhaust manifolds (which you don't plan on changing).

 

Thank you for your help, so if I run the 2 injector manifold I can use the 2 injector computer also?

 

yes. it is literally a replacement motor. if you are not changing out your fuel management system you will be fine.
