Post any small tricks you've learned or tips you have after doing things to your car. Things that you don't really see mentioned on the boards/vfaq.

When you're porting your exhaust manifold/turbine housing, you should use a used gasket to mark the outline of the hole. I used a new 7cm^2 gasket and ported to that, and when I pulled it all apart after a year running on it, I noticed that the sealing ring had crushed causing the gasket to bulge slightly into the exhaust flow. If you're going to use a new gasket, leave maybe a sixteenth to an eighth of an inch to allow for it to crush and seal fully.
