NA fuel system upgrade opinions.
In light of recent talk of upgraded TB's, i have come up with a few questions. On a NA car with intake, VI, and y pipe, would it be possible to do the following mods? Ported MAF, pathfinder TB, 370 cc injectors, 255lph high pressure fuel pump, and SAFC. Now first will the SACF be able to properly calibrate this combo on a NA engine, and still have a decent idle? If this mod combe is possible what sort of gain could one expect to see?

Re: NA fuel system upgrade opinions.
There is no need for a ported MAF or 370cc injectors on a NA motor. The only time you'd have to port the MAF is when it is topped out flow wise. For example the stock MAF on a 91-97 sentra/200sx se-r tops out around 210whp. We have a small 60mm MAF, the maxima maf is like 80mm! The only gains you can get is throttle response with the P-funk TB. That in itself should be worth the cost in upgrading it
