2.2 2.5 questions

[88jbody]

how diferent are the 2? I have a free long block 2.5 n/a out of a 91 or 92 caravan and am wondering how diferent the turbo to non turbo are, I am thinking if the 2.5 is ok to boost, I'll rebuild it and have a fresh engine. my car is aproching 300,000 and is stock bottom end so I am a bit nurveous of putting too much boost to it
