I'm looking for the best replacement for the OEM bypass valves on my R32 GT-R. Any suggestions? Power is around 500-600hp and the turbo setup is a pair of Garrett -5's.

Specific questions:

-The easiest to install (size and fitment- wise)? I'm planning to dismantle the front of my car this Friday and would prefer to order a set of bypass valve(s) before that so I can install them right away.

-Could I use a single big bypass instead of two standard sized? I've never heard of using a single bypass for a twin turbo but just wondering why not...? The throttle plates do close at the same time, thus the need for air circulation via a bypass valve should occur at the same time for both turbos?
