I had a 7064 twinscroll on my 2.0L WRX. Frankly, too big for me. I realize I'm in the minority and not chasing dyno sheets.
I'm not ripping the 7163 at all. All of the EFR turbos are awesome. Just for this community, 6758 is about as big as I think we ought to go. Really, the 6258 is plenty. Our drivetrains can take it anyway.
If I was going to build another Subaru with a 2.5L, I'd be going 6258 all the way. I like a low torque setup. For the miata, I wish they made a slightly smaller option. Just my 2 cents. V-band in and out. That's what I was holding out for on my next Suby build.
