For what it's worth, the T4 .81 a/r housing was reaching it's flow limits on a 6765 at 515whp on a DD (about 580whp DJ). The EBP was approaching 2:1, at 18psi of boost. On the larger displacement G37 that magic 2:1 would come in a bit sooner. This is all on pumg gas of course.

In other words, for anything past 600whp (DJ) a .96 a/r is the way to go.

I like it. For a street machine i think the 6266 would have been the way to go since back to back they were right at the 700hp mark on a supra at sound performance. Compared to the old 6765 they were putting down about 50hp more and it was 800rpm sooner. Now, that 6766 will put down more numbers but i don't think you will be pushing that stock block any further (at least i just assume) so that spool might be desirable.

I'll be switching from my 6765 to a 6266 since my 700hp will be within the range of 6266 on e85 and i want some extra spool for street tq.

Are the DE kits going to be on the right side of the car like this?

It's the .96 T4. This turbo was selected by the customer to reach a higher power figure than what we projected the 35 or 62 would do. The 35 on the Z did spool faster but made about 50 less hp right under 10psi.

The DE kit will be on the left side, buddy.
