The inake manifold is about as good as it gets as far as oem sohc goes...I wouldnt change it.
TB is pointless because honda makes the size is about right per application...gains would be very minimal (even when combined with the intake mani)
Inake...alright thats pretty standard...I'll let it slide
If I were you, Id take that money and just set it aside for turbo a little later down the road...thats where the power is. Sure there's N2O....but my opinion is ''nah'' on that.
The standard IHE is going to give you nothing but the feeling of wasted money on sohc in my opinion... Even those things with new intake mani and tb are still gonna leave you wanting a hell of a lot more. For real power from the sohc you need either boost, N2O, or a build...hell build and boost/N2O.
