Swap: Hemi to Hemi MDS
#1
I have a 2006 Ram 2500 5.7 Hemi, 6 speed manual, NOT MDS
I'm researching a couple options:
1. What is involved to swap in a Hemi with MDS, Ram 1500 06-08 Vin "D" 345 hp
2. What is involved to swap in Hemi with MDS and VVT, 1500, 09+ Vin "T", 390 hp
Will the engine controllers for MDS plug in to the 06 2500 harness?
Any known complications?
Will the manual trans flywheel bolt onto the crank from an auto trans engine?
Who sells the best software for doing my own tuning, part load and WOT?
Thanks,
Jim

So, the manual trans flywheel from the 2006 Hemi Non-MDS will NOT bolt onto the 09+ engine.
How about this combo: Will the manual trans flywheel from the 06, vin "D" non-MDS bolt onto the MDS engines from 06-08, vin"2"?

With the manual transmission you are going to HATE MDS. When MDS becomes active on the trucks equipped they unlock the torque converter to keep the whole truck from shuddering in 4 cylinder mode.
If you make the harness changes, I beieve the MDS programming is in all of the ECMs, just has to be turned on via SCT. I think the only real way you would gain with MDS is if you had a really steep gear ratio and short tires, like 4.56s and 32" tall tires.
Not to mention if you add a more aggressive camshaft than stock, you are looking at crazy Hemi lifter tick from the MDS lifters. I ran an 07 MDS engine on an 06 4.7 PCM and it ran in 8 cylinder mode with no hardware changes.
That being said, you are better off building around your current 06 engine. I would recomeend a Sidewinder cam and SCT custom tuning seeing you do not have a transmission to worry about adjusting.
