I have that one, the HE351VGT, it's got a huge turbine side, like 70mm exducer 85mm inducer I think with a much smaller compressor inducer/exducer at 61mm and 70mm respectively. It's water-cooled and variable turbine area (VGT - Variable Geometry Trbine) so I've looked everywhich way at how to use for low boost on my LQ4, but I just don't think it will cut it as a single. As twins, the turbine might be too big I fear. Also, Holset was tight-lipped about any details, especially a compressor map... the only one I could find on the nets was real sketchy, not to mention tall & skinny, which would be expected for a high-pressure low rpm diesel turbo. Really too bad because it'd be such a cool piece to have fitted under the hood

Yeah, Im at the point where the car is going back together. I found with my Grandnational, buy more turbo than you need then you can grow. Thinking about that GT45, but dont know if its huge, then I said the MP76Q should be smaller better to fit! Then there's the issue of getting some thing to tune with!

I started out with a holset wh2d and a hx50 for my rear mounted GTO. Which turned out to be the same 61mm turbos. Exhaust housing was huge. So BIG that I didn't need a wastegate at all. Would only make 4-5# in 3rd and 10# in od. Cheap though $300 new on eBay. My current master power t-70 has lasted for years, smaller/lighter, more power, quicker spool...double the price $600. But it is totally maxed out at 580whp

He probably means it has a 70mm compressor and 81mm turbine with a 96AR. Should be good for 700+ hp. So, yes.

Goood deal, I only paid 500$ for it and in the process of mounting it to a front turbo manifold using the truck manifolds, hope to make some good power.
