They are not major problems. i did a 00 b16a2 Si in my 98 dx coupe with no probs. i used a 98 ex wireing harness and a 98 gsr ecu and it went great for YEARS. I got 165 whp out of it and now i am rebuilding/replacing the block for a poor mans type-r set up.
long Story Short, a dohc swap would be best. Everyones done them, so all your info is obtainable. What you should do is a K series swap. I know quite a few friends with big smiles on their faces now because they switched from the b series to the k series engins!
