Holset Turbos...
what do you know about them. Know any really good resources about their sizing and compressor maps? Me and Darkblue TA have been talking about this tonight because it might turn into one of those junkyard projects if we find the right info.

The Holset units are good turbos. They are heavy for their size though, but very strong. Only drawback is the aftermarket support for them. Not much out their in the way of rebuilding and upgrading them. You can see more info below....

Jose, I did look @ their product range on their website, the only question is does that product range match up for a gasoline engine. I know Diesels like their air flow but it must be strictly matched up with fuel ( perhaps even more so than with a FI gas motor). Only true way to tell is to get a hold of a compressor map and air flow numbers. Just by looking @ a HX35W, the size appears to be around a 76-88mm turbo on the compressor inlet. Also, thinking about this, the cummins B motors are 359 cubes that max out @ about 3500 RPM (really firewalling it) vs. LT or LS1s with their 350 and 346 cubes but with nearly double the useable RPM range.
Guess I'll keep digging, since I just came across their tech. data online. I'll keep you posted, since this is my idea, and Darkblue and I are trying to figure out of it's feasible in terms of turbo sizing.
