5k is more than a trade for an srt 6? the new slk is almost as fast as the srt too, so your saving ten grand, even based on a completely guessed at number of 5k. and i wasnt referring to b series motors, but k series motors. they are the sizes i stated and line right up. of course extra work is required but in that app i describes its cost about 2k. 2.4 liter k series gets a 2.0 liter type r jdm k series head. Seems everyone is speculating, i was just wondering if anyone had any idea or not. not guesses......
