Hi i have a long question.. i have a 1995 Honda civic hatchback(automatic) and i was wondering if i should purchase the K20A or K20A Type R engine or any K-series engine, I also found out the B-series(like the b18) is good too but, would it fit? and is it worth buying for the hatchback(the hatchback is free so I'm planing to work on it... If not what would be the best engine for an automatic hatchback, I know it sucks that its auto but I'm planing to trade it for a manual but either way the question stands for both auto and manual.

& is an engine the first thing i should spend my money on, on a stock car? If not then what is? I've been getting a lot of different answers, but a nice sounding and high speed rocket sounds really tempting..
