wrong...sounds liek your gettin an k20a3 out of an Ep3 which would be the worst of the k swaps. If it's a Z then your in luck because its the most powerful one they have...I dunno what this guy is talkin about but they go for about 5-6 for a complete swap. Goodlucki think you may be getting a $2.5 k20. but the thing is, i bet its a k20z. which is worth ~$2.5 for a swap.
