Twin Turbo Time!!

[samsonite01]

Hello everyone. It has been a while

I’m going to be upgrading to a twin turbo setup on the Dodge! Thought I would bring you guys along on the adventure!

It all started with an oil pan leak about a year ago. I tried to snug up the bolts and made it worse.
Roughly two years ago I had the transmission out for more upgrades and had a seeping rear main seal. I replaced the seal and did not get the retaining plate sealed up to the oil pan correctly. This was the third trans removal and install I’m not surprised its leaking.

Now we all know that the proper way to do the oil pan gasket is to remove the engine from the truck…...and while its out…………..might as well spend some rainy-day money!!!

So, the build plan is;

Take the engine to a reputable builder. I will mention his name in a later post after permission. He is a known Cummins performance guy in my area. I will be dropping the motor off today and discussing upgrades. ARP 425s, MLS head gasket, maybe some head work, stock bottom end, Fluid Damper, 200hp injectors,

I have purchased a Twin turbo kit from one of the big diesel web sites. It uses a 62/65/12 over a s475. It’s supposed to be a direct bolt on with no fab necessary. It has good reviews. I do use the truck for work and often tow large loads. I will also be rebuilding the vacuum pump and upgrading the cold side tubing of the intake. I will be keeping the boost at around 50psi. Looking for about 550 to 600HP.

The truck is a 2001 2500 QCLB 4x4. Current mileage 209K. My supporting modifications are, a pissed off wife, full built auto trans, one-piece 6in aluminum driveline, Dana 80 with Detroit True Track diff, DOR track bar and steering box stabilizer, 08 HD steering links, bigger brakes, Edge Juice with Attitude CTS. 4in MBRP exhaust.

My fuel system uses a Fuelabs 100GPH lift pump in conjunction with an additional CAT 2mic filter, all the factory fuel system has been removed except the fuel return line. The lift pump is mounted on the frame rail down in front of the tank. I used a bean diesel bottom sump out of the tank. All ½ inch fuel lines with JIC fittings. A complete stand-alone power system relayed of the ignition for the lift pump. And of course, an Autometer fuel psi gauge in the cockpit.

Goals are to have a reliable 550 to 600HP work/play truck, less smoke and manageable EGTs.

Let me know what you guys think. Please no negative posts.

I am looking forward to hearing more about what twin kit you went with and how you like it. Good Luck!

Looks like a fun project. Keep up with some progress pics, it will help motivated some of the procrastinators; mainly myself. I'm really slacking with other stuff going on, so it's good to see some of this stuff get going.

Who built your transmission, and what flash/brake stall does is the converter spec'd to?

 

[samsonite01]

Good morning. The turbo kit is from Diesel Power Source. My trans was built by ATO Performance. The converter stalls at about 300 rpm less. (I could be wrong on that, I will call trans place and ask to be sure.) The guys building the motor are saying to stick with 75 to 100 injectors or get the smarty and then run some 150s. I have read all the twin turbo build threads and there are many out there running much bigger sticks with no problems. I also think the EJWA will do fine. I like the backdown settings.

Sweet. I have been eyeing the DPS kit and have heard great things about it from another guy on the TDR.

 

[ofelas]

Trans build sounds ready, and converter stall seems about right for the twin turbo setup.

I might add - keep a close eye on that DPS kit's long blue double curved silicone hoses.

You may want to use them as templates to make beaded flange aluminum/stainless tubes to be used with short straight sections of the appropriately sized silicone boots needed.

Goodies on my door step today! 2 big boxes!! I have to complement DPS on the packaging. Everything neatly packed and placed in the boxes. Thank you DPS. They also called and with a couple questions to confirm the order. Any one looking to buy from them can have confidence they get what they ordered. Here is a picture of everything layed out on the table. Now all i need is my motor back!

You should be able to run larger than the 100 - 150 injectors. I'm running 200hp Formula 1 sticks (same ones for probably 10 years). A buddy of mine had twins and ran 250 Formula 1 sticks, Edge Comp & water meth injection in his 01 6 spd. We were out in it one night and he was going about 20 in 3rd gear, comp box on 5/5 he just played into the go pedal for a bit - "my feet came off the floor!!!" really.

Oh, have fun with project and "sliding down the slippery slope of BOMBing". I "think" (I was told some years back) the only limiting factor to horsepower on our trucks is the VP however they should still make up to 600 hp.

Been considering something like this when the time comes for major maintenance. Subscribed

Small update. Waiting for engine builder.

Rolled out and degrease/powerwash engine bay today.

 

[Joe Mc]

Boy oh boy, looks like you're having fun!!!

Sweet project. It's on my list, but keeps getting pushed back. Keep us updated on your progress.

 

[samsonite01]

Yesterday was a good day! Picked up my motor! Complete rebuild top to bottom.
Block machined 20 over, reused stock crank, stock rods, new everything else balanced, moly pistons, 178/208 cam, custom cam gear retainer, ARP 625 head studs, HD pushrods, MLS head gasket, complete rebuilt head nothing crazy would be comparable to a street performer head.

Was clear that we are not building a race motor. The builder took it from there only upgrading whats needed.

I put the turbos on this weekend and take some more pictures!

 

[samsonite01]

Got the turbos on and engine in the truck today

 

[samsonite01]

Well shes all back together. Still some small things to work on. I have approx 95 miles on the setup. I cant wait for the engine to be broke in. I have the Edge box back down settings at 15lbs of boost and 50% throttle for the first 1k miles. After 1k oil change I'll start to crank it up a bit. The truck is much quieter and i can tell going to be much quicker!

I did cheat a little yesterday and turn off the back down settings off for a quick drive. At 25mph just into second gear i throttled it. This truck is going to be stupid fast. The turbos boosted to 35psi almost immediately. With the truck bed empty the tires broke loose with no problem. I jump out of throttle and back it when she shifted to 3rd same thing tires break loose! I have a Dana Truetrac locker in the rear. The truck jumps side ways on the pavement like my Polaris RZR1000 dose in the dirt!

Ok turn the saftey settings back on and be cool till shes broke in. I tell you what broke loose other than the tires....a hudge smile from ear to ear! Im still smiling this morning!

 

[Rich Poirier]

Right on!!
Thank you for sharing your project with us.

Looking really good!

Why wait for 1K miles? When I rebuilt my 05 the builder wanted me running it at the power I was going to use right away. Short WOT bursts at first, but after a few miles let her rip with the trailer in tow.

The rings will have already seated since you've seen boost... nothing else to really break in. Get the assembly lube out of there with an oil change at 500 miles and get to driving it!

Have you looked at the Quad V2 tuning?

 

[bigceltic]

Any new updates? How do you like the DPS kit? Were you able to find a better filter?
