In depth Turbo Discussion
Absolute Brutal truth from frustration and Logic.
If you don't care about the history of what I learned and how I learned it, Ignore the next paragraph.
I bought a 2012 Ram 2500 Quad Cab Short bed from my mother. She had been Tempted by, and given into, the whispers of others to give the truck more power. At 30k miles, It got a leveling kit, CAI, XRT pro, and an exhaust system to get rid of the DPF. The EGR system remained intact, but unplugged. Driven fairly, but worked until 80k, when I bought it. My 12 valve gave up the fight and I needed a reliable truck.
I drove it for 12k until the motor blew the head gasket. I figured it was the EGR cooler leaking, so I deleted it all except the throttle valve.
Finally realized it was the head. New gaskets from the deck up. ARP studs. Resurfaced Head. 10k later the overdrives started to shift HARD. $250 for H&S overdrive unlock for my tuner. Also buy an Edge CTS2 with pyro probe to monitor the truck. Got better for 5k miles. Then lost 6th gear only once driving down the highway. Saw it as the only warning. Spent near 10 grand on a Suncoast M3ga JR and billet Triple disk converter. 5k miles more. Variable Geo. Turbo is starting to lock up on start up because of soot build up. Spend $2,500 on a Fleece Cheetah. I like the exhaust brake and the ridiculously wide boost range, otherwise i would have bought a 2nd gen swap. Now to the meat of the matter.
I was 1 mile from my house when the stock turbo gave up. Compressor wheel came apart in about 20 pieces. Nothing got in the intercooler. Limped it home. My buddy and I installed the Cheetah in one night. Thankfully, I had it sitting in my living room. Was procrastinating from pulling the stock. I got less than 2 hours total drive time from the turbo. Shaft snapped off inside the compressor bearing and oil pressure forced the turbine down my exhaust into the muffler. Contacted Fleece because I have a 1 year warranty. 2 weeks and 93.00 in shipping costs later, I recieve a replacement. Installed on the truck the night I get it. That night (morning) I test drove the truck after a good break in procedure. Exhaust brake kicked on for 2 seconds at cruising speed (60 mph quarter throttle) then wend back to normal operation. Wrote it off as a dirty MAF or MAP sensor. Cleaned them and put the truck up for the night. Over the next week, the events not only happened again, but increased in regularity. Finally got tired of it. Obviously it's a bad actuator. On a turbo that i bought for 2,500$.
Let's talk about 2nd gen swaps.
I see many kits out there. The most tempting of which is the BD super B kit. After some research, I find that not many people like the s300 frame for 6.7's. So I researched the s400 frame. I use the truck for daily driving, mostly highway and city. I see that a common swap is the 475. seems excessive and i'd imagine it would suffer from extreme lag at low RPM. So the s465 is what I see as a good option. Except now i need to know what turbine will be best. A.R? I see 1.10, 1.0, and .9. Am I wrong in choosing the 465?
I tow medium fairly often. I daily drive it in stealth mode the most. I also enjoy beating up on the occasional powerstroke in the back country 1/4 mile.
Future plans include a 475 or 480 compound, EFI Live, and a Fass 150 Lift pump.
My goal is 650 on max tune, 575 clean.
So I ask you this:
Stick with the fleece and make them honor their warranty? or 2nd gen swap it?
if 2nd gen, What turbo (Specifics including compressor, turbine, and A.R) will provide the best for daily single and small in a compound?
What are the benefits of 464, 465,466? Turbine Size?
Who's EFI live tunes should I buy? (I live in Idaho and want them CUSTOM tailored to MY truck, not box tunes)
I'm at wit's end. The options are endless, and your combined knowledge is more than I could hope to amass in years.
