the f22 --> h22a swap is very very easy compared to all the other swaps out there. if you have not bought your h22 yet, i suggest going over to hmotorsonline.com because they have some very good deals on complete swaps, they will sell you everytihng u will need to do the swap incluing a 100% start up gaurantee. it doesnt get any better than that. the website will tell you what is included, but simply put, they include everything you will need excpet tools and such. the only other thing i would consider changing is your gauges.. there is a different redline for the h22 vtec compared to the f22... dont wanna rev too hard without knowing what rpms your at ya know. good luck
