not really but I need to know if I'm missing anything to swap turbos, and install down and up pipes.

I have:
up pipe gaskets both ends
down pipe gaskets both ends
turbo gaskets
2 CEL fixes

Is there anything I'm missing? (besides tools etc..)

Do you have the usual upgraded injectors and fuel pump to go with the new turbo? What are you doing for engine management?

Most definitely yes. Do it right the first time and just wait.

it could be very, very bad.....you will starve your engine of fuel, and could potentially burn up your piston rings, or even worse, throw a valve.....I would wait....because unless you drove your car like grandma, and stayed OUT of boost all the time.....you will need bigger injectors/ fuel pump.

yea, injectors and fuel pump are a must. Oh and when i did my install i lost a lot of coolant so when you get it started back up, you should bleed your coolant lines if you lost a lot of coolant in the process of changing your turbo to eliminate the air bubbles in your coolant lines. And you should also upgrade your spark plugs NGK iridiums are a good choice.

I was told as long as I turn the boost to around 13psi I should be fine.

But im a total greenie when it comes to stuff like this.

BTW its a stock sti vf-39 turbo, if that makes a difference.
