OEM turbos trust me. I had ported the exhaust manifold a bunch by hand when I was doing the build and basically did all i could to the engine to get her there (balanced, line bored, cylinders honed, new pistons, etc). I was running 17.2 psi of boost. I did not see the A/F but I was told (and have no reason not to believe) that it was very rich. I was running good ol Texas 93 octane, and have never felt so much as a ping from detonation (yes I know you can't always here it, but I do know what it sounds like thanks to my buddies supra). I can't seem to get anymore pressure out of these turbos no matter how hard I push it. I am guessing that I have freed up the flow so much that the turbos can't keep up but that is just a theory. From what I understand the big restrictions on this car have been freed up (intercoolers, intake, exhaust, and the manifold a little). I am open to other peoples thoughts though. The bad news is that passenger side turbo is starting to smoke a little, but that just means I get the Disco Potatoes next!!! As for dynos and making any numbers you want on them, I guess I don't know how you would do all that. Basically I showed up at Intercrew and said I want a baseline dyno to see how I am doing so far. I will tell you she pulls hard but really feels like she is running out of breath at the higher rpms.
