    ok cool, that's great info..

    now, i seem to remember you saying that you couldn't get more then like 12
    (???) psi out of the 36 turbo correct?

    i actually installed the n9tea turbo on my car a while back, seemed like
    after i started to up the boost, my (??) rod bearings went downhill, fast.
    car now sounds like a diesel between 2500-4000 with little load.

    thanks again for the info,
    august
