rear mount turbo qestion I found this turbo online which appears to be a hx40/50 hybrid turbo. Just wanting some insight on how well this would work on a stock internal ls1. If I purchase this turbo I will be attaching a p trim garrett t4 exhaust housing with a 1.00 a/r.
Holset hx45
Compressor Wheel (7/7 blade)
Turbine Wheel (10 blade)
Inducer Dia. 67.00mm
Exducer Dia. 99.00mm
Inducer Dia. 76.00mm
Exducer Dia. 64.00mm

Should be workable. I used this website to help make a decision on the turbo that I bought.

Basically fill out the data and select the turbo you wanna install or one really close and see where the data points fall on the compressor map. You want the points to be in the most efficient part of the map but if they aren't it will still work, just less efficiently as long as most of the points are on the map.
The really big issues that you will have with the rear mount is keeping oil scavenged from the turbo. A pressure check valve on the oil feed line, a good scavenge pump, and a bit of accumulation tubing below the turbo before the scavenge pump help keep that under control.

I used the calculator to determine if a cheap ebay turbo would fit my application. I selected the turbo on the calculator that was closest to the one I was looking at buying and then confirmed that it would work. When I got the turbo it was very good quality and have been running it for a couple of months without problem. I would suggest that you find a new ebay turbo that is closest and buy it.
