Slant 6 225 swap

Well it's a stock 225 and I got it about a week ago and my friend drives a 2008 Toyota 4 cyl and he just out right smoked me I don't want a fast car just something better then my friends and all the guys at the car show I went to said I should do a 318 swap I'm only 21 and this is my first car so if making the slant six faster would be easier on me I would do it ... I just don't what I can do personally
