i think the stock turbo inlet size is 2 inches, i just used a rubber coupler from ace hardware, it was for like drainage pipes or something, it never leaked or anything, what is the point of using silicone(i forgot)?

 

^it won't burn or something what kind of intake do you have?

 

92 if I remember correctly.

 

60mm or ~2-3/8". A 2.5" coupler will clamp onto it.

Rubber plumbing hardware has no place in an engine bay. It will eventually harden due to the heat, the crack and leak. There are industrial grade rubber hoses available that are suitable for engine bay temps and cost a lot less that the inflated prices you pay for "performance" silicone hoses.

You people need to stay the hell out of plumbing stores...
