Hi I have question recently I bought Rb25 s14 and my car has t4 top mount turbo which has 3 inch intake and then air flow sensor I was wondering how can I put just 4 inch intake straight on a turbo what's gonna happen with air flow sensor cause right now from 4 inch turbo to 3 inch intake pipe I think I am loading air flow?

You opt to put the MAF on the FMIC piping and run a blow thru setup. Or, go PFC D-jetro (or any other stand alone ECU setup), get rid of the MAF all together.
