Tuning Need a line on where to purchase a dual transfer port with low-side port

You could drill a small hole on the other side of your existing one and step it up till you get what speed you want. Just a suggestion you looked at both the places I would have only other place would be contact fx I'm sure they will sell you one they sold me a 500mm shroud when I couldn't find one I just sent a email and they did so over emails otherwise I don't know
 


You can't just drill a hole in the other side. You would also need to mill the slot to align the barrel as well.

I just sold one on the classifieds got it here but they be sold out of the .25 sorry.

FX got the last parts I ordered to me in just a few days though so you might want to just order from them directly.

True I forgot about the locating slot oops sorry
 
Thanks for the information. I tried calling FX USA without luck, no answer, so I emailed them with a request for more information.

I also emailed 910 asking the same question.

Shoot straight!

It's getting close to Christmas and with the supply lines so screwed up already I would imagine it's crazy for all of the vendors about now.

Good luck.

Apologies, didn’t notice you were after a low port as well, pre-java over here. I can’t imagine it being too hard to drill and notch for the low port.
