Hey y’all I’m currently running the Garrett T-3 factory turbo on the truck with factory piping. I’m only running 10 psi right now. I plan on running a larger turbocharger with the 3in down-pipe to a 4in exhaust. The engine already has head studs. My question is what brand/type of turbo would be a good fit with the IDI and how can I reroute the piping from the turbo to the exhaust manifold and hopefully run more direct and slightly bigger pipes. My goal is to have better performance, lower EGTs while hauling, and around 10-18psi of boost.

Any thoughts or suggestions?
Many thanks in advance.

I know there's people out there that modify your existing turbo, classic diesel designs comes to mind.

Going with a different turbo would get tricky space wise. Maybe a borg Warner s300 series would fit?

Hot pipe size isn't really that important. Whatever your turbo has already is satisfactory.

Good luck with your venture.

 

ive not been on this forum for many years, but im begining to embark on another aassembled truck and im back now, so im a bit shy to call out my ideas, but here goes.
when getting into larger turbos, space limitations and higher heat zones, there might be a different route to take, especially if full on race engine is not your goal.

Remote turbo. put it under the cab,or in in the bed.
this approach, when properly designed, takes care of a number of issues but raises others. In my view, the benefits outweigh the potential costs.
imagine,
a dually 4x4 ranch truck, flat bed. use an isuzu cab over air intake and filter system that mounts to the back of the cab with an overcab snorkel and scoop. a turbo more or less under passenger butt. the layout would have a 90 degree off the hot side going back. the intake pressure side is a straight shot up the bell housing into the hat. an intercooler can be fitted or better a spearco heat exchanger. oiling is no issue either, an ebay turbo and some piping . redesign the y pipe for two pipes running to turbo for twin scroll and your in.
i know folks are gonna tell me that the turbo will lose heat, that the piping sizes are wonky, that....blah blah. but it has been successfully done on trucks and can work well in the idi situation where space, heat and noise are a consideration. this may not work well over 15 psi i cannot say. in my case ten psi is my goal, usable reliable power on a fresh 6.9.
gassers have gone well into the 30's with remote turbo. not that that means anything in the diesel world.
a remote turbo is crying for water meth injection and so easy to do

 

Alright so depends your skill and access to tools that will make it easy or not. Thier are upgrades for the OEM turbo like wicked wheel and such. R and d has upgrade that drops in from what I understand. Any other turbo will require some figuring out. I did a s300 based turbo was suppose to be a 66 mm more like 60. With a t3 to t4 adapter that raised turbo up enough to clean the OEM intake hat that I changed to accept a boot. But than thier was clearance issues with the cab. So do you have the tools and skills to make one fit? Trust me it's more work than you think but its wicked fun of your into it. Other option is to just run the stocker till she blows. Plug the waste gate hose wire the gate shut more if needed and let do its thing. I'm doing that my Dd right now. I dont even have a boost gate or egt gauge. Cleans the stock pump decently enough.

That's my new s366 I'm setting up on 6.9 with an r and d idi hot side kit. Just started setting it up last night.

 

I wouldn't recommend above 15psi of boost on that 6.9, studded or not. I stretched arps at 20psi.

 

Thanks y’all imma defiantly research those idea and hopefully come up with something.

 

when I go Turbo it will be electric

 

There are You Tube Videos guys sticking a Leaf Blower down the intake.
Was looking for one of them, but came across this one using an Electric
Turbo.
Watch the whole vid or advance down to about 14:00 where they do the
Dino run w/o it and then 2 runs using the electric one.
Chicom Turbo gives you more House Power...LOL

Right Charlie .. I wasn't talking about the China Crap

here is the Torque AMP version

Garret has been working on them too

so far great success on smaller engines like Audi https://www.motorauthority.com/news/...ocharger-works

Right now I have a BLDC motor that will spool up to 15K RPM using 96 volts the controller can run off an inverter with 24V input and in Theory I could probably make 5-8 PSI Boost with an AR turbo..... I wasn't looking for Monster HP



BTW I guess we should really call it a supercharger since it won't use exhaust.... BUT YEAH I love the Twin Leaf Blower Videos

 

The engine was 100$ and it ran, so I'm not really worried at all. Factory head bolts still too. Excited yet?

 

Sure am!

My stock headbolts that had been reused held 15psi all day long until I had that piston failure.
