    M44/42 build

    I know the lowly 4 banger isn't too well received here but I will share anyhow. The build is as follows:
    M44 block, crank, rods, lower timing cover.
    Late M42 6mm head mildly ported and 4 angle valve job. (Could not get a 15deg to fit)
    Early cams, intake cam ground to 212deg at .050" and total lift at .390"
    US s50 pistons milled to 11.5:1 with total seal rings. Total displacement is 1950cc I believe
    12.5lb M20 SMF conversion.
    It's finally in one piece aside from what needs to be transferred over, right about when I'm ready to leave on vacation. Should be in the car and running in the next month or so.

              Cost is somewhere between 2k and $2,500. I did my own valve job and port work so add 400+ $$ for that. I milled the pistons as well. But that includes a $550 m44, with a cracked head I found out later, balancing everything and lightening the flywheel. The rest of the machine work, cam, m42 head, rings gaskets etc.
              The tune will be extra. I spread it out over 2 years so the wife barely noticed. That and my current m42 just won't blow up.

                  If you were doing that set up NA, what do you think the HP would be? 160ish?

                    Hoping for around 175 at the flywheel hence the 350.../2 post. Might need to save for ITB's to really open it up. I will be playing with e30 and e36 cam and intake manifold combinations to see what makes the best, most-usable power before dropping bank on ITB's, however.

                        Looks good. I see you have what appears to be an R1200GS in the corner of the first pic? ADV riding ftw.

                          Ever think of becoming a detective? It's a workmate's bike but it is a BMW r1200

                            It's in the car and running, my build thread is at m42club.com. I just added the COP KIT from hqautosport and love it. Pic won't load right now. Will try to get a smaller one.
                            While there also a lot of challenges from running OBDII, I love having data steam capabilities.

                              Did you remove the old motor with the tranny? Or did you leave the tranny in there?
