I'm wondering who's offering non-hybrid turbo upgrade options besides the 2 above companies. CTS' kit is out of stock anyway, and everything APR sells is simply more expensive than it needs to be, so they aren't a viable option. To put things in perspective, I'm stage 2 with EQT's OTS 91 octane tune and I'm itching for more. I've got my eye on their Vortex XL, but wanted to consider non-hybrid turbo's as well. I like the Borg-Warner EFR turbo that APR's kit offers, and I know Garrett is coming out (or has already) with a new line of turbo's and that's likely why CTS' kit is out of stock, so I'm just weighing my options before spending $5k or so for more power.
