hey im new to this but anyway i have a rb20 that was from NC. the turbo is going out and is leaking oil. I want to put the 25 turbo on it but do i have to do anything else to it if i do this? I live in south dakota and was wondering if anyone knows where i can take it to get it worked on. maybe around denver, minneapoils, or chicago.

it all bolts right up, take the wastegate actuator from your 20 turbo and put it on the 25 turbo so you'll still be running ten pounds of boost instead of only 5 pounds from the 25 actuator
