Why doesn't Garrett or Borg make these for tuner applications?

First off, pet peeve:
Cummings is a poet (and probably a **** star, I didn't look that hard). Cummins is a power equipment manufacturer.
Read what I actually wrote, please. I never said that no diesel turbo will work in a gas application. I said that no VGT diesel turbo will work in a gas application. There are people that do it, but nobody who road races or really abuses them (that I can find). I also know of no OEM that uses VGT turbos on gas engines (aside from Porsche at $5200 a pop).
It's very easy to figure out how much horsepower a diesel turbo will make on gas engine - it's about the same amount of horsepower the diesel turbo made on a diesel engine. Airflow is not magical.

According to Wikipedia, 3 manufacturers tried it in the late 80s and early 90s (Dodge/Shelby, Honda, and Peugeot). Nobody else was dumb enough to attempt it until Porsche in 2007, so that should give you a pretty good idea of the difficulty of making it work.

IMO I think one of the GT2/997 turbos would be best suited for someone in the 300-400 whp range. But I'm not rulin git out yet. More info/details to come tomorrow. If I pick up 2 would anyone be interested in the other?? They'll most likely only sell then in pairs because thats how they come.

Update: Just got off the phone with Full Race.....said only the Porsche's ECU could control the vanes(electronically) and as far as he knew there was no standalone ECU compatable for vane control/tuning....

At the core though, you're still pretty much just talking about a stepper motor. I know some people have taken apart the HE351 vane controller and wired uC based driver to it directly, so I'm sure something similar is possible with the porsche turbos.

Update: Just got off the phone with AEM tech and they dont make or have anything that can control the vanes.....
I would love to see this done but I'd also just like to get my car running so for now looks like I'll just stick with ole trusty 3071 and make 500 whp.....:-)
Anyone wanting to try I can get you a turbo, or 2

Please stay out of my threads as you are dumb as ***. When I said 650 CFM that's referring to peak flow. With a VGT a turbo that flows that much at peak power, could spool anywhere from 1-3 thousand rpms sooner than a traditional turbo depending on engine and powerband. Thats why I'm suggesting possible usage. As you see I'd like to make more than 200 whp like you, kthx. gby
260whp and there isn't enough horsepower in the world for you to ever keep up with me on a track. I also have a running, turbo Miata. Beat that.
