for what I use the car for I would like more power but the torque of the ka is sufficient it actually works quite well on the track and in the mountains. I can keep up with sr cars easily during a drift I just carry more corner entry speed and keep it floored almost the whole time instead of lots of modulation its more fun that way for me I like lots of throttle. Mine just has intake I think with headers, pulleys, exhaust, decent clutch and lightwieght flywheel it should be a lot more fun. btw I have a lightwieght one piece driveshaft that makes a huge difference and I run lightwieght 16's they help also
but yea if I had the money I might roll the sr but right now the ka is a beast and keeps up with my skill level. I think it is helping me be better than if I had 400hp.
