honestly KA= the fucking suck.... i had a SR for around 1 year nearly beat the living fuck outta it... traded it cause it was fucking up on me a guess what my friend fixed the bitch... (wiring fucking nightmare for me) he took his time fixed it and the bitch still runs fucking good.. SR is better than fucking KA any day anyone can say you have to rev to get power bull fucking shit my SR would peak full boost in 2nd gear from a 10 roll and hit full boost at 27-2900 rpm.... and pulls through rpms quickly after 4 k... SR will rape any lightly modded KA or ka with intake hearder and exhaust... my ka right now Has intake and apexi exhaust 3 inch catback and guess what its fucking slow. do yourself a favor just pick up a sr... stock 205 hp... get boost controller fmic,turbo mani, 3 inch dp and 3 inch exhaust.... 12-15 psi you should be around 230-240hp range untuned prolly more idk im just throwing numbers.
