66/88 is a good setup. Only issue is gating a hypermax mount is a pita. I've thought about doing a compound setup using one. There is also a 71mm h2e that I'd pair with a s510 but the 71mm doesn't seem as stout as the 66. I don't see why even a 62mm h2e with a 80 - 83mm wouldn't be a good setup.
I have already gated my hypermax set-up with a turbosmart 45mm wastegate, this is the main reason I don't want to switch to a T4 mount.
It was a PITA to wastegate. I had to lift the body an inch all the way around to get it to clear the firewall.
I have a boost controller sitting in my garage.
I feel like I might be a good candidate for compounds?
So you think the GT47-88 would pair well with the modded h2e?
I'm pretty sure my H2E is 66mm and not 71mm, Beans is the one who modified it.
It would be DD street driven. I tow 8,000-10,000#'s a few times a year.
