98EKHATCH

Hello, this is my first post. I own a 98 Hatchback CX, and am looking to do a swap before i even think of doing anything else, i need some advice on which swap. I wanna do either a k20a swap, k20a2 swap, or do a built ls, turbo. IM trying to figure out pricing i figure the k20a swap to be about 8000, 6000 for the k20a2, and im not sure on price of a fully built ls turbo, i just know i can go pick up a ls motor right now from a buddy obd2 for 350 dollars, im just not sure on what to do and would like some advice on what u guys would do. Sorry for incoherent rambling
