Nismo intake

Caravanshaka · 06-13-2009, 10:35 PM

so, if the stock airbox is pulling air from outside of the engine bay (most airboxes I have seen do this), then the gains seem to be coming from either:

a) more filter area, allowing more flow
b) less restrictive piping between the airbox and the intake manifold
c) possibly larger diameter tubing around the MAFS tricking the ECU into leaning out the mixture for a few extra ponies

Could we build an effective intake system utilizing the stock airboxes but improving the flow between them and the intake manifold with aluminum piping? Could we build a whole new intake that takes an "airbox" design that sucks air from the front but still uses a conical filter and velocity stack inside a more efficient airbox in the stock location for the best of both worlds?

maybe I need to learn how to weld aluminum now....
