You need to give information of what you want!! Do you want it to handle well? or is it just a drag car? how much power do you want? do you want it as a reliable driver? ETC...ETC.. A civic with a h22 will not handle very well!! too much weight in the engine, my freinds is a nightmare, even with coilovers it only helps aliitle bit!! If you want a fast civic which will handle well you shud stick to a b16 or b18, b18's are great, it just depend if you wanna go turbo/supercharged or N/A.if you do go b18 a teg engine will come with a LSD, a b18c4 (1800cc civic vtec) comes with a LSD after 98. no point in havin power if u cant put it on the black top! think about all these types of Q's and what you want, Then ask ppl to help
