    M42 turbo starter/partial kit

    With California smog laws getting more onerous every year, it's become clear to me that I'm just not going to be able to run this stuff on a street car. A shame, but time for it to get out of my closet, my 318iC is going to have to go in a different (BAR-able) direction.

    What's on offer here is most of what you'll need to get an M42 turbo operational with a Garrett T3.

    The centerpiece is one of Otis' (good & tight) first run of M42 turbo manifolds, with new OEM gaskets:



    The turbo is the only part of this setup that is not BNIB. It's off of a 524td, which uses a .42/48 T3; a great starter turbo that will provide quick spool on an M42. It's got the very common 5-bolt exhaust flange, which means that as you're ready to upgrade later, bigger turbos that are a direct replacement will be very easy to find. It's still a bit dirty (you should have seen it when I pulled it out of the diesel car... ew) but I flushed some fresh motor oil through the center section and was happy to discover that the wheel spun freely and had *no* radial and very little (<1mm) axial play.



    Coming off the turbo hot side, you've got an ATP Turbo "Ultimate Internal Wastegate" setup intended to replace the stock internal WG. Compare this to the IWG that comes on a T3 and it's pretty readily obvious why this flows better. Has a 3" v-band outlet. Comes with a new Garrett wastegate actuator (in the brown box). Supposed to completely eliminate boost creep @ higher pressures. Read more about it here: http://www.atpturbo.com/mm5/merchant...de=ATP-WGT-023



    Completing the "exhaust starter kit" is a 3" Magnaflow cat, and a 3"-2.5" reducer since I have a custom 2.5" exhaust on my car that this stuff was supposed to mate to. The boost-crazy Swedes on e30tech tell me that the first 18-24" of the exhaust after the hot side are where it's most important to flow well; after that, things cool down, which is why I planned the exhaust setup this way.



    Now for the "cold side" stuff- I didn't go crazy expensive with the BOV, since a BOV is a BOV if you ask me. But it's here- everything you'll need to take care of that requirement.



    I intended to run a water-air intercooler with this setup, straight across the front of the engine, in order to minimize piping volume and keep spool quick. Never got as far as buying the actual IC, but I did snag a good length of 5/8"ID hose and the connectors you'll need to plug into the IC if you choose to go the same route. This diameter hose matches the Bosch Mustang intercooler pump outlet size, which is what almost everyone who runs water-air uses. Also pictured: new Walbro 255/hr fuel pump, and new M42 fuel pressure regulator- if you don't replace these parts when going turbo, you are Doing It Wrong.



    Finally; air intake bits. Pulled this from a running M42 car that was getting a swap. The bracket thingy holds your AFM in place after you remove the air box, and the flange will let you connect the IC piping to the AFM. Filter goes on the turbo inlet, obviously.



    Shit You Will Still Need:

    -larger injectors. mine will be sold off with my ITB setup, and they're only marginally big enough for a low-boost setup, so you can't have them. sorry.
    -fuel management. you can cheap out and go with a RRFPR, but PNP-megasquirt setups are so cheap now that you really don't have a good reason to do that.
    -downpipe. this'll need to be a custom piece to connect the v-band wastegate to the 3" inlet on the magnaflow cat. take it to the exhaust shop.
    -intercooler. ditch the included water-air accessories and go air-air if you want to, or you'll just need a barrel-style intercooler (suggest looking at http://www.frozenboost.com/ ) and a bit of piping & silicon connectors (ebay that shit).

    $1000 plus actual shipping from 94608; after receiving the $1k I'll haul this stuff down to the fedex office and get a quote to your location. shipping will occur on receipt of shipping payment (i'm doing it this way rather than charging for a worst-case shipping scenario to the east coast, when you might be in nevada or something).

    Thanks for looking.

    Oops, forgot one thing under "shit you'll need": oil feed/drain for the turbo. Also an off-the-shelf item.

              if i don't hear from above poster, i'll start selling parts off individually; less convenient, but i'll make more money; so PM if you want the whole thing.

                If you decide to split this stuff up I would be very interested in that good&tight T3 manifold, the 5 bolt to V-band / internal waste gate, and the garrett waste gate actuator.

                  Okay, nobody's sacked up and bought the whole shebang, so splitting up.

                  First on the block- the turbo manifold. Otis charges $525 for a new M42 mani- you can have this BNIB one for $400.

                      BOV piping is 2.5".

                      Taking offers on everything.

                        Still interested in manifold, ATP internal wastegate to v-band flange, and the garrett wastegate depending on what psi it is for. PM me dude.
