    What "brand" ebay turbo have you been using?

    And…did you send it out for professional balancing and shaft inspection / magnafluxing before using it?

    There was no specific brand, just super t70 written on a plate attached to the compressor housing. It sat on the wall of our shop for four years before I used it. I never sent it off for any work.

    I've had good luck with them, if you do your own work there isn't much to lose. Right now im deciding to buy a t4 exhaust housing to put on my 67/65 or buy an ebay for about 100 dollars more. Love my precision but the thrust play is pretty bad. Pretty amazing itt made all that powet t3.

    How much with the t3 hot side?

    Sounds like you trust the ebay turbos. Frankly, other than mostly gossip, there's a LOT of people buying them and mostly good results. Another good one for Myth Busters…"ebay turbos".

    I guess at the boos levels you run, you're gonna go through turbos quicker? Can't you get your 67/65 redone for less?

    Im looking at a rebuild plus a housing, it would be cheaper to go ebay but I know the 67 will push the power im wanting to push on the new setup.

    I am running a pte 6765 Dual BB.
    I currently pushing 25psi on it (forged internals) on my vg33.

    Its a load of fun. I haven't had any other experience on other BB turbos but my previous was a t3/t04e journal setup.
    Obviously, given that the 6765 is a bit bigger than a t04e there is some lag but overall the spool time is quick!

    I am sold on PTE and will never go any other route.

    How much power are you making at 25psi?

    I honestly don't know.

    Last time my Z was on a dyno was when it was getting professionally tuned for E85.

    I have since then added Schneider 274-70h cams and upped the boost to 25psi.
    It was tuned at 15psi which was at 396rwhp (Denver altitude, ~5500 ft).

    Similar boost with my setup put down in the 525-550whp range

    Very nice Rick!

    Thats probably where I am sitting with my build, except I am running 25psi on the 6262 Billet (vg33 forged).
  • #225
    Was boost going up towards the end of the runs, that bump in the torque at the end is substantial but its not in the 15psi graph at all? Great numbers rick, beautiful car too.
