Im not sure if its the K20 or the K24

If you look at your engine block, it should say either stamped into the block, or on a little metal label.

2002-2004 RSX-S is the k20a2 series.















2005-2006 RSX-S is the k20z1 series.

K20. The K24 is used in the TSX .

K20, but definitely a very under tuned version compared to the type R's K20 :P so, go hard or go home, type R or just forget about it. U'd want a TSX over a RSX type S, but if you already own one and you realise you've made a tremendous mistake because you thought a type S would be fast and wanted to do up a replica cheap version of the type R then it's ok. Don't cry, u've failed but it's not the end of the world or anything.
