I found a very nice, low mileage motor for very cheap but it says it does not have an air pump. My question is, can I install the non air pump motor in my air pump car? Are there any internal differences or can I just use the long block from the non air pump car with all my air pump accessories. I need to know as soon as possible as I'm definitely placing my order today. Thanks in advance!

 

Long blocks the same. SAS and EGR are external bolt ons

 

Just transfer the gear you need to keep the pump over to the new engine, that way everything will be "normal".

I came across something about deleting the air pump and not tripping the check engine light but I don't remember where it was. If you're pump is working it might be easier to just transfer it over.
