Should I buy another car?

I currently own a 2004 Honda Civic Si Ep3 with the HFP package. It has 159k miles and is in perfect running conditions. I really like the way the car looks and how unique and rare it is, but I'm deeply disappointed in how underpowered it is. I want to buy another car, preferably an S2000. I feel like I could get a decent amount of money if I sold the EP3, should I sell it and buy an S2000?

There's something called a k24 engine swap which will cost less than a s2000
