3116 turbo upgrade ??

I found this on ebay and was wondering if anyone could tell if it would work for the 3116. It says they are for the 3126B or C7 motor, the nsn # 2950-01-518-3535. If anyone knows what to look for to be able and verify if it would work that would be helpful. Thanks in advance

I would like to know this also as I have my fuel turned up and just need a turbo

Hi, for my hp upgrade I used the turbo from a 290HP engine. That with the fuel adjustment was all that was necessary to REALLY wake up the 3116 in my LMTV. I have the parts manual and could look that up but it will be a bit.

Saw this as well...curious

You could put an S300 on it but you would want bigger injectors. The S300 comes on the 350hp rated 3116. The turbo from a 3126 will work. You would need some fuel adjustment though to get any gains. so I would just adjust the rack and leave the stock turbo on it.

On the version of the turbo listed in that ad. It will work. I would honestly cut the wastegate rod in the middle and thread both ends and put a turnbuckle on it so you can shorten it so it will hold longer and produce more boost.

There is a 600hp version of the 3116 but its a special cat build inside and meant for marine applications.

Some power upgrades for the 3116.

The turbo part number for the 3126 is 4R8915 and they don't offer a rebuild kit for it anymore. I might end up going that route and getting one from an 6x6 but was just exploring other options and cost$$.

Please refrain from posting links to ebay, per the rules.

Yes, please let us know the part # of the turbo.

MPG will very due to differences in weight of right foot. Mostly negative affect to MPG.. turbos add air to 1. Be able to add more fuel for more HP, 2. Assist in lowering EGT. In the TM range is the same for the 225hp and the 290. But experience shows if more HP is available it is used.

Sorry for the ebay link but here are the specs and I was wanting to know if this unit would be plug and play besides the fuel adjustment or if any other mods would be required to fit the turbo. I know the 6x6 turbo will work but they seem to be harder to come by and for 500$ this seems like a cost effective way to get to the higher HP as long as its not too much turbo. Any info would be appreciated

What are the 3116 turbo specs?

I do not know but I purchased the turbo that I had asked about and it appears that it would bolt up, the gasket matches and the intake and exhaust are the same. I haven't hooked it up yet since I do not know how to adjust the fuel properly, if anyone does or has a recommendation that would be great.

I haven't made any progress at all, I need to find a shop that would do the tuning but haven't had any luck. I wish there was a write up on how to dial in the fuel mixture after installing a different turbo, but i haven't found anything. If i make any progress with it I'll let you know.

Uh. Simple. Put on turbo. Increase fuel. Install Pyro and boost gauges. Load truck with weight or a heavy trailer and find a hill. May be a challenge in Texas though

While driving monitor Pyro vs boost and foot position. Blowing black smoke under Load vs its pulling power at a certain point. You will know when it's right after a few adjustments

Its mechanical. Noone is gonna get a good setting from only 1 adjustment

This is the tag off the one I received.
