Why would you want another engine, what's wrong with the one you have...does it smoke, burn oil, run bad, etc.? You want a swap but don't want a GS-R engine? What are you wanting...for it to go faster or look better/differant? I'm just trying to figure out what's going on, what's going through your head...what's the basis for wanting a "swap"? Most importantly, how much are you wanting to spend...you're gonna have a budget on anything you do, how much are we looking at...i can tell you exactly what you can get done for that amount.
