So i’ve since brought the new trooper into the family by what else, taking it apart. The bad turbo came off not long ago since it was locked solid. Luckily, I found out that its a T25 standard flange! So in my search I came across a cheap GT2876r… Now, I dont know much about that turbo, other than its a big front end on a small back end. Is there any benefit to having that hugely mismatched turbo on the diesel? Its a 2.2l, 4k redline, non-intercooled… but i could pipe a side/top mount in it no problem. So, what do you think that turbo would do on that thing?? ---

Here’s your compressor map: ![http://www.turbobygarrett.com/turbobygarrett/images/catalog/Turbochargers/gt28_images/GT2876R_705330_2_comp_e.gif](http://www.turbobygarrett.com/turbobygarrett/images/catalog/Turbochargers/gt28_images/GT2876R_705330_2_comp_e.gif) You could probably run that at 12-15 psi (with a good intercooler) and see some nice gains if I am reading the map and your input parameters correctly. ---

I have NO idea how to find Pr, VE, or mass flow on that diesel… i’d need to see if there were diesel guys out there that played with this stuff. ---

I missed it on ebay. It did $430. I’m going with a stock replacement, just b/c the bottom end sounds like there is something in there wanting to get out!! ---

If it’s a small turbine, I think it’d hurt more than help. Remember how much exhaust diesels produce. They use huge turbine housings. Not that it matters now though, I suppose. ---

I hear you, but this is a 4cyl, 2.2l diesel. Its not exactly setting the world on fire. The stock turbo is a small t25 frame with the only suprising thing being it having a .63a/r turbine housing. ---

Externally gated, much larger A/R, and much larger turbine? That should be fun 😃 ---

Yea, that makes more sense. I heard “diesel” and immediately thought huge displacement. ---

You had better turn up the fueling a significant amount and install an EGT guage if you ever want that turbo to spool and produce much in the way of boost. ---

I’m still not clear on how the troopers fuel pump works and where the adjustments are. I might get a haynes manual as much as i hate them. I will definitly have the proper gauges to watch what is going on. ---

I know absolutely nothing about the I.P.'s on the Isuzu-- I am only familiar with Bosch pumps. Who manufactured that pump? ---

I’ve looked online and can’t find what it could be.
