no its not.
healthy t-25 @ 1 bar setup right will do 280/280.
or in most cases at least 210/240. with a powerband equal to that of an n/a ka.
craig, id hit up ka-t.org and freshalloy. some of teh setups there are freaks, but the majority of people can put down good FUN power. the best part is you can use all SR parts, minus the manifold, so its all plug and play. s13 sr fmic will fit ka with a longer TB coupler.
