what would be a better motor than any k series motor??????? i mean i didnt even pay for the k20a3 my brother gave it to me cause he wreked his civic si. so im just putting money into it. and there no such thing has a sucky motor or better motor its what you do with it. ive seen a geo metro motor thats 3 sylinders running 8 flat. anyway ima build the k20a3 so i can put it on my 91 integra i dont see alot of DA running with k20.
