I did mine at skyzone... u can try going there. They'll send it to a machine shop to port... as they don't have the necessary equipments. I think most workshops also will have machine shop connections... try ask your own workshop and see lar. If you wanna go SkyZone and ask... go to 4GTuners.com there.... got map to SkyZone. Its our sponsor workshop.
so alvin, wat did they do to ur intake manifold during the porting process? they enlarge ur plenum opening? wat abt the inside of the intake manifold? the runners etc. hope u can provide me with more details. oh, and not forgetting.... the price :) hehehe. anyways im a member of 4gtuners also, so got discount ah?:P
