I have a guy that has all the h22 parts you want for a decent price. Personally, my h22 and the lsd trans was $2690+ shipping, but that was in 2006. You can get them cheaper if you buy them from someone personally. Google is gonna be your best friend to see which motor you like the most. I enjoy the h22, it has a decent amount of torque, for a Honda. What are your plans for the car? Yes, you have to change the axles with an h22, or, you could do an H2B and keep the b series axles.
