I'm fin ta do a swap and Im torn on what to first. I plan on going with a b20zblock b16a head combo. only problem is that this is an expensive build and Im not that patient. the way I figure I have two choices. a full b16a swap and then start saving to build a block for it. once I have my bottom end build Ill pull the engine and get the head modified to fit the b20 and drop it in. the other choice is to find a b16 tranny axles linkage int. manifold etc, a b20 long block and a b16 ecu. then I can save the money for the rest of the bottom end components, and have the head all ready to go for when I rebuild it. My question is, which setup would "tide me over" best and would an sir ecu run a crv head well?
