Aidwin, Nah, yours is fine, just thought you wanted to upgrade to a bigger turbo later down the track:p
Mike, A GTR FMIC can handle 500hp worth of air:D
I wouldn't say that the performance gain from the Greddy plenum is huge, and with $1k+ there are many mods that will give you better bang for your buck, but I'm happy with my purchase, both for power gains and looks:D
