I did the math, if I put in a 10.8: 1 with a .5 overbore and build up the engine I will get some real decent gains, someone has done the build without the higher compression pistons and he is putting out 180whp (give or take 10-20whp), and a proper k20 swap will run about 2-3 grand more. it is all about budget. O and there is camshafts, and the full valve spring and retainer upgrades available, you can get up to stage 3 cams, but I am getting stage 2. Pretty much everything is offered for the D17A2 (civic EX) now. Also everyone is doing the K20 swap, I am not that big of a fan of it. paying 4 grand for 160hp, and still I would have to build on that, or for the RSX-s motor that is even more. it is not like I am looking for 300HP, just to max out my current motor, and put alot of people to shame when I show the dyno chart.
