I currently started rebuilding my engine. I have a D15B8 engine. Found out it is very weak and won't get much more power out of it unless I put 16 heads on. I want to find an engine with power. Anyone have any suggestions on what I should drop in it and be able to pass smog. What ECU or wiring do I need? Do I also need to change tranny?

Thanks Snoopy. I already know the different types, well at least a few of them. Which ones give me the best bang for the buck and will pass smog. Passing smog is the biggest deal for me right now.

bang for buck and passing smog, i'd go with a b18c1.
