I bought a used HKS T04R off of a freind and im pretty sure its supossed to be a V-band type outlet on the turbine housing,however somebody welded on a 4 bolt square flange where the V-band was...now i need to find a flange to match it for my downpipe and i need a gasket too..does anyone know what kinda flange this is and where i could get it and why someone would do that to the v-band housing? ill post up pics later..

 

if you measure the distance between the bolt holes you can send those measurements to atpturbo.com and they should be able to help you.

I think the t04r should be the same flange as my fc's t78, they just finished making my flange that goes from the 4-bolt to a 3" v-band, and then i got the v-banded 3"->4" transition. They now sell that flange on their website, its like $99 regular price.
