    AWD Speed 3 Project - Halfmilespeed3

    Quick Update on my Rear Suspension Plans: - I completed the assembly design for the inboard rocker arm & pushrod actuated setup. - I am working out how much bracing I want to add to support the main tube and how I incorporate the parachute mount to anchor directly to the cage vs just the rear...

    AWD Speed 3 Project - Halfmilespeed3

    I'm not going to lie...the thought has been bouncing around in my head but looking at what has been needed so far and what I expect in the future...there isn't alot that is truly one-off. - RMM for Speed 6 trans in MS3 subframe - Could do diff mounts for the CX7 (technically not required...

    Ok, one more post...I guess I had too many images in that last one. - IMG_3845, 3846, & 3848: At this point I was ready to see it on the ground. With 255/50r16 on 16x8+38 wheel/tire setup installed, we set the car down and were pleasantly surprised. Fitment is on point, ride height appears...

    Last update for the weekend: This is the mock up test fit using the CX7 subframe with the MS3 trailing arm, toe, arm, camber arm, and lower control arm. - IMG_3838: We removed the complete "moving" components from my MS3 subframe and bolted them directly into the CX7 subframe. Everything...

    AWD Speed 3 Project - Halfmilespeed3

    Continued update so each post isn't too overwhelming. - IMG_3828: I knew the front section of the spare tire tub needed to be trimmed and I knew that I wanted very easy access later on so i opted to cut the entire spare tire tub out of the chassis. This may not be the goal for others, but in...

    AWD Speed 3 Project - Halfmilespeed3

    Update from the weekend: - Overall, the process has been pretty straight forward and after some trial and error. - CX7 rear end in a whole is not the solution. It is a combination of CX7 and MS3 components to get the proper track width. Images showing removal of components: - IMG_3816...

    AWD Speed 3 Project - Halfmilespeed3

    Quick update this am: Worked on the rocker arm design. This will be a billet 6061-T6 AL material and fully CNC machined. Ratio is 1:0.7 This gives me more suspension travel for a shorter damper but I will need to run a stiffer spring rate to compensate...around 500-550 lb/in in the rear to...

    3.5” exhaust

    Simple answer is yes. And to answer your concern that your turbo outlet only has a 3" v-band connection...well that typical and ok. The turbine wheel exducer (outlet) is only 62mm (2.44inches) but that also doesn't matter in this case. The rate that the exhaust gas can expand and escape the...

    Just curious about CS 80mm exhausts

    Some of this comes down to material selection and manufacturing processes. In the grand view of things the 4mm (0.125") difference will not be noticeable or measurable. So 3" vs 80mm is essentially the same for 99% of builds. Now...the 3.5" (89mm) has a full turbo-back option or downpipe...

    I know two other guys that would be interested in jumping on this oppurtunity.

    I talked to the owner a bit. He worked directly with AWR/DG Motorsports to do the build. Knowledgeable guy and had the goal to keep the car very OEM like with that build. Moving on now because he jsut doesn't have interest and is boosting his SC400. He kept the CX7 outer suspension...

    AWD Speed 3 Project - Halfmilespeed3

    Quick update: Has nothing to do with AWD swap, but I pulled the turbo out to do a rebuild with a new compressor wheel and compressor housing from Xona Rotor. The new wheel paired with a larger compressor housing is much more efficient and should result is same or more power at a lower boost...

    Ya maybe a few years ago but I have alot invested into my chassis at point and want to stick with the novelty of it.

    I talked to him. Not interested in parting out right now and I'm not buying a whole car haha

    I suppose I could ask him about the transmission. Not sure if he is open to parting it out a bit.

    Unfortunately they are unique due to the PTO connection. From my research, only Damond has developed one and that was a group buy they did awhile ago.

    Factory is open diff in the front. I'm wanting to source one so that I add that when I add the dog box gearset.

    AWD Speed 3 Project - Halfmilespeed3

    Hello Guys & Gals, As winter rolls in here in the PNW, I am preparing my car for an AWD swap. I see that @Roger Mesler has been doing fantastic work with his and I have gleamed some info from it; thank you. While I haven't been great about documenting the many phases my car has gone through, I...

    CS EBCS Failure Analysis, Prediction and Troubleshooting

    That was our main test location and the compressor housing like OEM. The MAC bullet valves were designed for high vibration and varying temp locations and working at a much higher duty cycle then we put them through. Also jsut a note: CS is not the only company using the bullet style for...

    CS EBCS Failure Analysis, Prediction and Troubleshooting

    So voltage would actuate but function was not occurring. Thats an odd one. How long were they in use? Did these get sent to CS for investigation? I personally have not had a failure or issue with one of our EBCS units nor have we in the company. Not saying its not possible, just been...
