Interesting. I hunted for an hx27 for a while. Never came up with one. How much power at that boost level?

We have a company here in New Zealand called Motorsport Engineering who supplies Holset turbos. They can put a Holset core into pretty much anything, mostly into china chargers after they shit their seals. He also can custom spec turbo's to suit whatever you want. |

So 250whp in American power. I have no idea to read that torque units.

The way the tuner said the dyno works out torque is the torque at the wheels divided the diff ratio then times 1.1 for drivetrain loss. So you end up with 262FtIbs
