oh okay so you want to do an engine swap, I thought you're talking about tweaking the current engine.
Well remember, more 'cc' don't always mean more power. I think you mean the K20 when you say the 'Accord Engine'. Well, a K-series swap won't be easy, you'll need aftermarket mounts along with tons of parts and the whole swap (if done properly) will set you back at least 300,000.
Stick to D-series or even B-series if you're serious about this.
Type down what your requirements are and is the car daily driven or will you just use it occasionally? Like I said, everything depends upon your budget, so mention that as well.
