Hello guys ! Im going to do a b16b or b18c swap into my 96 civic coupe in the next month. Ill need a service manual for to reasons: 1. to help me in the swap. 2. to use it for reapiring and maintaining the new engine. Which manual do u reccomend to buy? Factory ? Helm ? Haynes ? Chilton ? Which will be the best for my needs and where could i buy it ? Thanks.
