Hey Paul, good to see some info up on this 7163.

Any chance you can comment on the boost transition, recovery time? Not the boost threshold that you can see in a plot, but what it feels like on the road in 2nd gear at 3500 when you go WOT.

Can you really tell the difference between the lighter weight titanium exhaust wheel in drive-ability?

To Geoff:

I tried calling you a few times, but you are obviously busy. I should (finally) have a 13 STI on order, and I want to know when I can actually physically have one of these complete kits in my hands.

Also, is there any way one can have your "1.5" scroll header, and then the appropriate UP to work with the SS B1 frame EFRs?

One last question for you:

-if we have to wait a while for the 7163 to come out, what are your thoughts on the 6758? I know Perrin did the one test, but the results seem skewed due to a possible TGV issue. Is the 6758 (all things being equal) a turbo that will have a few hundred rpm better boost threshold, but 30 whp or so less potential?

I am thinking of the following for a 2013 STI:

-stock or possibly aftermarket TMIC
-94 octane E10
-your 1.5 scroll system if available
-3inch TBE, with possibly a 3.5" HFC, vs a 3" unit
-TGV delete
-some sort of intake and inlet pipe

I have been waiting forever to purchase a car wanting 400 whp and Stage 2ish response, and I even spent a fair bit of time test driving used GTRs and 911s, but I think I kinda want the practicality of a STI. Please tell me I can actually buy one of these kits soon!!!!!
