      Awesome build, I'm glad to finally see some more engine swap options for these Kompressor series Mercedes.

      Just put up another short video of the car driving down the road...
      https://www.youtube.com/watch?v=YrBlPZHep4E
      Drivability is really good and the power just keeps coming on...trying to take it easy until evaluations are complete then the powertrain will be pulled for revisions.
      Found the stock clutch (24V BDF 6 speed) wont hold more than about 8-10# boost without some slipping, so looking into clutchmasters 400 next.
      Cant wait to feel this thing under 20+ psi...

      Oh that boost.
      When you blow up the bottom end I have a BDF short block you can have free for shipping. No head or oil pump.

      Hey man you are the best, cant tell you how much we appreciate the support we get on here, actually have a BDF and a few AFP so we should be able to develop this car and have some fun!
      Every body just keep in mind that this is a junkyard car and motor that was put together with parts that were laying around and the only new parts are the ARP hardware, gaskets, rings and injectors.
      Wanted to keep the first build cheap and simple with a 12 valve but stopped and looked twice at the 3.6DI motor that was sittin in the junkyard, hopefully no one will twist my arm.
      After we get a clutch in this thing that will hold some boost we will be turning it up, letting it eat, and "sending it" all at the same time so stay tuned. Hopefully it will pop a wheelie before it pops the first motor....

      Thanks for that!
      We looked at your MK4 GTI build and it looks awesome!!
      Your attention to detail and self discipline will pay off in an amazing vehicle, and a real "sleeper/keeper".
      Make sure you put a Valentine One radar detector in it when you drive it on the street...

      We are trying to get this car prepped for a trip to the track and, because we don't have the extra "flow" for a new set of wheels and tires, decided to just "try" a set we had laying around for the Z28....


      [IMG][/IMG]

      We used a 1" adapter to go from 5x112 to 5x4.75 and it looks like we can make the 26x10 M/T`s work with a little fender rolling and an airbag in the springs...

      [IMG][/IMG]

      Will make every effort to prevent this combo from turning the tranny to glass....


      [IMG][/IMG]

      Been tempted to just back half it and put a nine inch and a powerglide in there but would rather just play it out and see what it will hold..... trying to stay all German for now..
      Got a 3.69, 210mm center section out of a 300 SL ,welded solid, sitting on the side lines and ready to go when the 3.27, 185mm unit gives up the ghost...
      Will provide updates and pics
      Thanks for looking

      Wanted to provide some updates on the project...
      The stock fuel pump was not keeping up with the engine under high boost so we installed a summit 340lph E85 compatible fuel pump.
      [IMG][/IMG]
      While we had the FSU out we retrofitted a MK4 fuel level sensor resistor card and float onto the MBZ FSU housing, this way can keep tabs on the fuel level in the "pump side" tank chamber...
      [IMG][/IMG]
      [IMG][/IMG]
      We had to get creative with the in tank fuel hose connection at the pump but it worked out fine..
      [IMG] [/IMG]
      Because we are currently running 93 octane pump gas we needed to install a methanol injection system to help reduce pre-ignition under high boost..

      [IMG] [/IMG]
      Also installed an EGT sensor in the rear exhaust manifold.
      [IMG][/IMG]
      Here is a shot of the turbo exhaust flange we forgot to show on earlier post...we milled out the flange and welded in at 3 inch pipe with a divider to block the internal waste gate, which is also welded shut..
      [IMG] [/IMG]
      Working on a VSS solution so we can get the speedo working.
      [IMG][/IMG]
      We also had a little fun coming up with a trunk badge that symbolizes a new standard of performance in this car...
      [IMG] [/IMG]
      More updates and video coming....

      Thanks for the kind words and enthusiasm, we appreciate it!
      We haven't been to the track yet because the stock clutch is barely holding, it seems to be seating in more with every test drive but we are sure it wont hold with the slicks on it and we don't want to just lay waste to the clutch just yet. Trying to save up some cash to get a stage 4 clutch then we can go to the track and see what it will do... also curious about the weight of the car cause we been weighing everything coming off and going into the car and looks like we were able to reduce the weight substantially and we can actually weigh the car at the track.
      Just put up another video driving the car around under mixed conditions..
      https://www.youtube.com/watch?v=ZV1BQUXD6O4
      We made a gauge panel out of plexiglass and mounted all the gauges in one place, still working on getting the speedometer working accurately, should have it sorted out soon...
      Were also getting a lot of boost creep and determined that the WG diaphragm is leaking so that will need some prompt attention.
      You can hear momentary audible preignition in the video, occasionally as the boost sweeps past 10# and before the alcohol system delivers its mix.
      We haven't logged the ECU yet but suspect it is pulling some timing when that occurs.
      The oil pressure and temperature are looking good as is the coolant temperature...
      The engine cooling fan started acting up near the end of the test drive and resulted in elevated oil temp... will sort out the fan issue also
      We noticed that the MK4 coolant gauge does not always show fluctuations or spikes like an aftermarket gauge does, this is probably due to sampling and averaging. Have actually seen our MK4 GTI VRT boil over with the gauge reading steady at 190 degrees, probably due to localized hot spots.

      We finally managed to take the car to the track for some testing in the quarter mile...

      A link to the YouTube video is here https://www.youtube.com/watch?v=oQVg-_qm3Rk

      The car proved to be quite reliable under some severe operating conditions and the clutch was the weakest link....

      Development continues.....

      Ah you were the Kompressor at Fixx this past Saturday. Well done, the car got consistently faster on subsequent runs. It does seem as if you had some type of issue/failure on the last run that day.

      Yea that was us at FixxFest, what a perfect day for a drag race.
      We finally got a chance to test the car and after running it on a 12# spring we started to turn it up...The hood was only opened for short cool downs and to check for leaks..
      The low 12 second pass was at 22#s...the clutch took a beating as we made a total of 10 runs before it broke...but we knew it would eventually let go, just glad that the motor and tranny held up to 1.6 60fts with 26x10MTs maintained at 14 psi, could have gone a little lower....
      We will continue to experiment with this combo and we are sure that it could have broke into the 11s if it would have gone a few more passes...
      Was well worth the effort to take down the high tech AMG with the low tech VAG....Ahh yes

      More to come

      Kicking myself for not coming and checking your car out in person. Anyway, next time. Good job again though.

      Want to give some updates and bring you up to speed with this project as we look in a new direction..

      No, not an OM606 swap, not yet, but definitely going to adapt a Mercedes automatic to the VR6 for further abuse and testing, this is a 722.351 out of a 1990 W126 sedan with inline 6 pertrol motor and it is not an electronic transmission, will basically need engine vacuum supply to modulator and some regulating linkage adapted for the control pressure cable, more on that stuff later....
      We started out with a VW auto flex plate from a 09A and the MBZ flexplate from the M103 CIS-E motor...grinded the rivets off to get the ring gear and fitted onto VW plate

      Tried to get it as centered and true as possible by putting it onto the lathe.

      Then we stitch welded it together on the back side and drilled the converter bolt holes through the plate. In order to clear the starter we had to shim the flywheel out from the crankshaft with a .100" shim we made from the center of another VW flex plate...

      We had to trim the nose off the rear of the crankshaft so we can get a little more clearance for the converter pilot..

      And we still needed more clearance so we made a little more space,.075" with a re-purposed valve spring seat fly cutter and a home made bushing..

      We cut another .055" off of the converter pilot..

      Then we took a 3/4 inch thick plate steel 10"x10" and rough cut the center with a hole saw then drilled and countersunk the flywheel bolt holes and then cutout the outside dimension with a larger hole saw, a little cleaning up on the lathe and we get this home made converter pilot,

      Next we had to make some spacer pucks for the converter mounting lugs …


      We broke out the old skill saw with a carbide tipped plywood blade and carved up a spacer plate out of 3/4" T6 aluminum and cleaned it up on the mill with a 5/8" end mill and arrived at this set up..

      Notice that we can easily switch back to the 6 speed at any time by removing the spacer plate and swapping the flywheel...
      More to come...

      We forgot to show a few mods we did before going to the track so here they are...
      Needed a E-brake to load the car and for some occasional drifting so we took the pedal operated apparatus off the kick panel and mounted on the trans tunnel like this

      After routing the cable around to the tunnel we made a mounting plate and bolted it together...

      Made some clamps for the bracket..

      Then we repurposed a spare jetski handle bar that was laying around..

      The whole setup is adjustable and seems to work pretty good so far..
      Moving on to the rear differential, we didn't have the flow for a LSD so we just went ahead and welded it up and it seems to be holding up pretty well so far..

      The hardest part was cleaning out all those little spatter balls

      Anyway, this is what the engine looks like when it is pulled for service..

      Because we know it will have to be removed several times during development we tried to make it modular with emphasis on minimizing loss of fluids during the R&I process..
      Oh yeah, and this is what happens when one of your pressure plate straps break during a low 12 second run...

      Probably should have taken it a little easier on it at the starting line with the 26X10 M/Ts
      So we will see how the automatic trans works out next and actually prefer an automatic for the track.
      Stay tuned

      Hey man just wanted to let you know that this swap is absolutely crazy! I’m doing a vr6 12v turbo in a rx7 fc mated to a cd009 and I’m facing the same sump problem and I would need your solution if possible! My email is [email protected], thank you!
