I have the above combo with the LilJon stage II cam. Expect HP in high 6's low 7's on 93. The exit of the S475 is at 5" od. How far would you guys stay at 5" before reducing to a more manageable side to navigate through all the chassis/trans areas?

I have the same turbo. I reduced mine down to 3.5" due to space issues. I made this choice against everyone who said not to do it because it will choke it out too much. I have yet to start it.

Run it as large as possible as far as possible then split it to duals if possible and they obviously should be as large as possible.

Mine reduces to 4" about 5" from the turbine .

4" all the way passed the rear axle .

OK. Ive got room to run about 12" of 5, reduce to 4", a 90* turn to get under the car, then split into dual 3". Sounds like I'll be fine. Thanks guys.
