howdy guys. iam mostly on 240sx forums. and thought id get some insight on here.. i have a rb20 swapped s13. heres a dyno run of my car without any mods really..

YouTube - ‪dyno run 3‬‏ (http://www.youtube.com/watch?v=JbFhYU_ujP4)

yeah slow as shit i know but since then...

ive gotten but havent installed yet.

-a nistune
-a hx30 turine
-z32 maf
-650cc detchwerks injectors

i have to have the manifold custom fabbed up this for the hx to fit.


question is iam aiming for 350+whp now. would a front facing intake plemnum make a big difference in doing this?? i was looking at this model.
