I have a bigger turbo and big injectors so I don't know how that applies to a stock Benz.

I'm guessing its not a benz?

He's got a landspeed race truck with a 617 in it. Even without a bigger pump, I'd say the IC is worth having if it helps even a miniscule amount

Gas or Diesel, the problem is the same: you can't get more power by just adding air. You need to add fuel as well. Can't do it without uprating the delivery valves on a Diesel or the injectors on an EFI gasser. Save your money for something more sensible.

It's my understanding OP wants better efficiency. But i also wonder if there is any sense in putting an IC on the stock turbo.
Upgrading the turbo to something modern would make much more difference and would be a lot easier i think.

Yup. The T3 was designed in WW2. Adding more air is pointless with stock pump, adding more air earlier in rpm range will do wonders.

The advice i got on 4btswaps was TD04HL-19T, HE221, HE211 or even a T25.

I'm looking for Mileage, I'm also putting in a 2.47 rear end in if I can find one. I know that I have to up the fuel level, I understand that a lot if people believe that a intercooler is a waste of time. But I'm pretty sure everyone that is saying this doesn't have one or has never tried if I do it I'll be sure to tell everyone if it pays for itself.

Better efficiency is better milage. The stock turbo has a lot of lug it doesn't start producing boost until the rpms get pretty high. A newer turbo that spools sooner would allow you to produce torque in lower rpms
Good luck with the intercooler, frankly i'm considering one myself but i have upgraded the turbo already.

Foot idea. What turbo you running

I got this:

I haven't fully tested it though since my swap hasn't been completed and i heard opinions that it may not work to well.

I'm thinking about this brand. Maybe not thus extect turbo, little bigger than I need. I'm just looking to put my mpg up in the 30's. I've got 32 once put I'm at 28ish most the time. I have the intake and exhaust manfolds off to clean up the gunk. Hand cleaned the ports to increase the flow. It was pretty bad.

Those are all non t3 flanges, that should tell you something.

Who's AWIC do you think is in that W123 above? You cannot push enough fuel out of the IP with stock elements without melting pistons to make an IC worth it.

Buys fine German engineering, made of some of the best metals in the world, puts chinese crap on the intake...
