which engine for my crx?

hello everybody. i'm creatin' a car as kind of an advertisement for the power of my tuning garage. the exterior is pretty out of this world already. which motor could i put into my crx (with some fabrication of course) that will give me the most power? thanks for any help, and i'll be sure to show you guys the end result when it's all done. I'm postin' the whole project on my website, but it currently isn't up yet. I'm going to wait til' the car is done. Hopefully it'll attract some business.
