.57 trim wheel in .50 housing?

...Sigh... it was a lot simpler back in the old T4B days when A/R was a number and trim was a letter! Big Grin

I got one of the ebay t3/t4 57 trim turbos and it was over boosting, even with the clip off on the acuator arm. What it was is that the wastegate hole was 2/8 smaller than the stock turbo, so I ported it out to 7/8 stock size. That was last weekend, one time I got on it real hard and saw just a little boost creep. I have a feeling all have to go in and port it out just a little more.
