my first swap took me 12 hours straight...B16a into a 1990 civic si, me and my dad put it in he is a big mustang guy so i taught him a little about honda power, haha...It was pretty simple just alot of work and my brain was fried after that, and wiring up the vtec and sensors...but overall alot was learned, it was fun, now my engine uns great, and it kicks my single cams ***..
