If you are all praising the Nismo plenum, have any of you seen results from them?
I've been lucky enough to have a couple of diffrent plenums on our car.
For an all round driver i would recomend a single 90mm unit, this is if you arn't going to make over 1000hp.
If so, i would then step up to a 100mm unit.
As for the ITB setups call Troy from XS-Engineering over in the states and ask him what he thinks of the Nismo itb plenum.If you don't want to call him, He told me that they back to back tested the Nismo to the stock plenum and it made no extra power anywhere and it felt the same on the street.
