There was a thread not long ago asking where to get an adapter that goes from a v-band connection to I/C boot. also where's a good supplier for 3" boot hose? I know I need a 90 for off the turbo - I/C, not sure yet for other end.
For a 3" to v-band connection you will have to get one made. The PPE kit is a 2.5" and most other options are 3.5". A good place for hose is racepartsolutions.com.
I also would not recommend using a 90* boot if you are running a charger of decent size. I would go with a banks tube and a straight 3" boot.
I have a PPE v-band connection that will work with your stock intercooler pipe and boot if your interested.
Okay, the factory hose off turbo is a 90. Just figured I'd go up in size. Was gonna try ATS on flange. Didn't because I figured they'd want a ridiculous price.
