I did.If i were to compare both cars in my own personal experience the evo has a lot of power to gain with some minor tweaks here and there, throttle response is quick compared to the Z in my opinion.In terms of speed I guess both cars are the same but if you drag the two the evo will get ahead first. Although mine wasn't stock at all.I have done a lot to the evo just like what you did to your STi which only gave me problems.The car was fun & fast but it is not reliable anymore to my daily driving.The Z is more of a lifestyle car you can bring it anywhere and people will give stares
.You can get more power if you will slap on some turbo and it will out perform a stock evo on drag or track.If I only had the money I'd still keep the evo although I didn't so I trade it
just my two cents
