Does anyone know the size of 2005 evo 8 turbo inlet

 

2.5"

 

Thanks im trying to do a boost leak test and looking for help i need to find something to go over the inlet so i can put compressed air and look for leaks

 

i ran into a problem with the 2.5in couplers....it wouldnt go around the turbo inlet.....the solution was to let it sit under hot running water for 5 mins to stretch out the coupler.

 

Well, yeah, 2.5" is the inner diameter. It has a thick lip and rim, so you need a larger one. I can't remember what size mine is, but it's larger than 2.5" and very snug. I don't have to heat it up, but I do have to work it on there.
