i had some pics in my ct-27 thread years ago, i think they are gone now, but basicly they just grind out the ports to make them larger.

thats what i thought.... i figure its not like a port/polish on a head where flow rates need to be considered (knowing where take off and some times add material) pretty straight forward.

i didnt have a problem when i was running a 2.5 set up but with my 3 i see boost creep.

ima do the work myself when i get some time.

do i just make the ports bigger OR can i just make it one large oval shape port???

any one got n e pix to share? after looking at some pix of other turbos with wastegates ported i think i just have to enlarge the two holes rather then making it one big hole cus the waste gate seal is only the two holes and not the part in between them right?
