Turbine inlet? Yes, it just hasn't made it to resellers yet.

What "indy engineers" told you that?? There have been >>zero<< indycar turbo failures over the last 3 years, this is something we take very seriously. The aluminum bearing housings work great when watercooled (this is mandatory -we tested this in the lab) I was with tony kanaan, he loved the new EFR7163 turbos. Dario Franchetti's guys loved them... Andretti's crew loves them. Buddy Lazzierre and his dad were blown away. Bobby Unser said its the most significant change in turbos since the 1970s... so yeah the guys we talk to have no complaints. would like to know who you speak with

correct, the 7163 is the largest and highest flowing rotor group possible to cram in the B1 frame turbo. All of these B1 frame turbos (6258, 6758, 7163) share identical outer dimensions and plumbing connections.
Aside from the rotor pairs, the only hardware differences are in the way of new turbine housing options. We have larger 0.85 A/R in T25 IWG, Vband-IWG and Vband-EWG, and there is a brand new twinscroll T4 0.80 a/r IWG.. these will all carry over to the other B1 turbos once 7163 supply stabilizes. That being said im really excited to try a twinscroll 7163 on everything i own (F150, SR20, evo, bmw..) its a very interesting turbo. once i can get my hands on one, the 8374 is coming off my evo and t4 0.80 7163 is going on, i plan to use every bit of the comp map!

no problem - going from a 71mm gt2871 vband-ewg to a 71mm EFR vband-ewg would be a great comparison. the transient response of the EFR is unique and since the 2871 does not shine in this regards, I think would be worthy of consideration. as others have mentioned - dont underestimate the 6258 and 6758, those turbos absolutely rock for the 44lb/min->53lb/min airflow range
