no probs dude..

common EG swaps are..
1. b16a (as mentioned above)
2. AUDM b18c (little more expensive than the b16a, better torque)
3. JDM b18c (little more expensive than the AUDM b18c but a better engine)
4. h22a (very heavy but very quick in an EG, expensive and difficult to fit)
5. b16/b20 conversion (lots of torque, not recommended b20 isnt strong enough)
6. k20a (very very expensive, like 10k+)

very basic runover of some of the swaps available so u can search on each of those engine types and learn a bit more about each and decide

also..
b16a usually found in some del sols, JDM EG's, EK VTI-R's etc
AUDM b18c found in vti-r integra's (DC2's)
JDM b18c found in JDM integra type-r's
h22a usually in preludes
k20a from the newer integra's (DC5's)
