a few of us are using the precision turbos and couldent be happier with the way they perform, my rb26 with a 6765 T3 .82 made a lazy 600rwhp on 26psi, another mates 26/30 with the same turbo makes 600rwhp on 26psi, we also put a 6262 T4 .84 on my old man's 32GTR and with a peice of shit hks log manifold made an easy 500hp @ the wheels on only 19psi on straight 98 pump fuel with stock bottem end, good proof for the people whinging about having to run 35psi and e85 to get good power results.. its a load of bullshit, my mate with the 26/30 gained 40hp @ the wheels with a 2psi boost increase, and during tuning his car was making 430rwhp on something like 14psi. these turbos dont stop making power, you can just keep going and going and the car will just keep making power.
