I have a used M44 DASC Superchager kit for sale. I bought the kit used from bimmerforums a few years back. I think it had about 20k miles on it. I started making sure I had all the parts and started gathering any additional things I should replace while in there. I never got to install it. We are working on getting new cars so this won't be getting installed.
-M44 (96-99) that was on a 318ti. You will have to find out if it fits a sedan or an E30.
-What I believe is the full kit minus one 45-degree bend on the intake and the MAF brackets that support the intake. You can run without them or use something to brace it if you want. It's not needed according to downing.
-Extra fuel rail and injectors that can be sent to get cleaned a head of time
-boost gauge with pod/hoses
-new manifold gaskets
-new prelude air filter. Use this instead of the K&N so you can run a proper paper filter
-coolant hoses that attach to the block that always break anyways
-new accessory pullys
-new gatorback belt
-a few new pieces from DASC
-all new hoses
-check valve that adds about .5psi
-new hardware
-extra TB, I believe a M3 one
-air filter heat shield
I also have the install manual and parts list from DASC on .pdf.
