hey, i just received my sfmu(paid 60shipped on ebay ;) ) now i only got 2.72 disc and silver spring, the question is can i run 440cc injectors with this, I have been reading a lot on this subject, and i know there is a post, on what disk/spring people are using, but the only guy that has 440cc injectors is using 2.72 disk and black spring, so would silver spring work, if not where can i get disks and springs thank you

is everything there?

as far as i know the bits and pieces are only available through vortech. www.vortechengineering.com as far as the disk/ring combo i couldnt tell ya. but aside from some missing disks/rings and what appears to be a modified vacuum screw, it looks complete. but dont take my word for it i just got mine not too long ago and im having issues with it. btw, i have that same hex key set

you can try the spring you have. I believe it has worked for some people, I really don't recall which one you are going to need. Install it and see if you can get your idle down to where it needs to be with that spring, if not you need the other one. Idle should be <20, I can't remember if it's supposed to be 14-15ish or 17-18ish.

ok, thx guys
