I guess a small update is in order.
I am working on a desmog setup for this engine. I just have not been able to get the custom intake to play nice with the MAF sensor so the s*** is coming off. Just to recap, the MAF basically controls EGR input and that is what makes my engine run like s***. There is a pedal dance procedure that cummins has outlined to re-calibrate the system, but with my custom throttle setup it does not work, most likely that is my fault due to my custom throttle setup. Truth be told I swapped back to the cummins pedal assembly and it still did not work, I even moved the TPS with a screwdriver and bad my wife count off with a stop watch. I bet I took 50k miles off of my engine by having it hit redline before there was oil to the bearings, what a stupid ****ing idea.
I am working with a local tuner who currently has the ECM and is doing some tweeks as we speak. I designed some nice block off plates to allow for the removal of this god awful mess. If you remember back to the beginning of this process, it was the EGR that ruined the installation of this engine in the 80 series. They literally could not make it worse than they did, I suppose it would be great for a cab over style truck but not for a normal vehicle.
Had I done this initially I could have moved the engine back another 1.5'', then the adapter would look much more presentable.
Here is the intake block off, I designed in a little "dot" to serve as a guide in case someone wanted to drill and tap it for a boost gauge. This is 6061 Alum as you can prolly tell.
On the exhaust side I used some 0.25'' thick 304 stainless. Just look at all that new real estate. What an improvement. I should have done this months ago, but many searches turned up nothing for R2.8 tuning. I know I will get the "I told ya so" speech from at least one member on here.
