Update on the Ebay T3/T4 with V-Band
So from a week or two ago, I said I purchased this turbo:
http://cgi.ebay.com/ebaymotors/ws/eB...#ht_5222wt_939
Some people had doubts about the downpipe clearing, and im happy to say it does. It is not optimal (the bend out of the turbine housing) But it works well.
Please ignore the **** welds, all I have to work with is a Harbor Freight Flux Core! They are structurally in tact tho.
The mani is a BEGI unit.
Spool is ok, laggy but hits hard which is what I like

So someone clear this up for me once and for all cause I see that almost everyone here (with an internally gated churbo) has a downpipe that is fairly small (2"-2.5") that TRANSITIONS into 3" and eventually dumps into a 3" exhaust:
isn't that 2-2.5 bottleneck right after the turbo and before the 3" making the whole exhaust basically 2.5"? Isn't your exhaust as free flowing as its most restrictive section? Or is that logic not applied in this specific case?
I want to know cause its almost impossible to have a 3" COMPLETE downpipe with an internally gated turbo. (in fact I'm pretty sure its not)

You're right, it is almost impossible with our setups. To answer your question; as long as the diameter eventually increases to 3" or whatever it is you're looking for, you'll be ok. What's NOT ok is an ACTUAL bottleneck. Example: you have a 2.5" DP leading to a 2"(or 3"!) cat/mp to a 2.5" muffler.... not good. As long as there is an increase throughout, you're good to go.
