Hi, just a quick question. Which ports do we use for the valve units? I've read in the forums that some use the "COM" and "NC" while others use "COM" and "NO" ports. I just want to make sure I installed this correctly. Thanks

"COM" goes to the wastegate. "NO" goes to a boost pressure source, like the compressor housing or the intake manifold. The 3rd port needs to to be left open.

Oh alright thanks. So this installation process is the same for both the star kit and hahn kit? Because I was aware that the wastegate is located differently between those two kits.

it says that in the manual. :P

Yeah I know, but the page after also has an installation procedure for external wastegates...doesnt the star kit have an external wastegate?

I dunno. Can't you tell us? I mean you do have the kit. Is the WG on the turbo or bolted to the manifold.

its bolted on the manifold. Sorry for the trouble, because one of my friends told me to use the other method (internal wastegate) and it didnt seem right to me. I just wanted to make sure, thanks
