    S52: Compression Question

    I'm trying to source a S52 at the moment. I may have found one and was wondering if these compression numbers seemed okay:

    cyl 1 - 192
    cyl 2 - 190
    cyl 3 - 188
    cyl 4 - 191
    cyl 5 - 197
    cyl 6 - 190
    1989 US E30 Cammed S52

      I would also get a leakdown test if you can, (on a warm motor)

            actuial compression numbers will vary depending on a number of things like altitude and such. The biggest thing to look at is spread/difference between cyls
