I think the n51 might be Canadian only and I think it is a 2.5L. Then again I though the 2.5Ls were called 323s. I've never seen an n51 powered car before. Anything I've seen is n52 powered. Anyone with a 328 should not have too much of a problem with this mod. The engines are almost identical and they both have the same ECU as the 330 and 325.
