Turbo Lab America Holset HE351CW turbine housing and 67mm shaft upgraded

Installed on a 12v when replacing the tired wh1c. Mildly modded, and dropped over 300 degrees on the pyro. Finally the answer to “I wish someone made a bigger housing”

Installed this on my stock he351cw compressor with a Wicked Wheel and prosource ceramic manifold. Great upgrade! Turbo comes in it feels about 200rpm later than stock but has great power in mid-range and beyond. Engine bay temps cooler, engine itself runs cooler, egts lower than ever and she tows better than ever before. Interested in seeing if i gain mileage as well.

Works great I paired it with a wicked wheel and the thing works amazingly. I didn't ask for the 12 blade kinda wish I did because cruising at 60 it spools 2 psi but will build quick once you put it under pressure. I wouldn't say it spools as fast as stock but I hit 41psi on it and that's the highest I've ever seen my truck, so I would call that a win. Deffinetly can tell the exhaust runs colder

Good turbine and housing, made all the difference in the way my truck runs, just wish it came with new turbo housing to manifold studs.

After installing this on my 2003 Cummins, I was not able to get towing EGTs above 1,170 degrees. I absolutely pounded the throttle to get it as hot as possible going up Whitebird Grade in Idaho ( 65 MPH, 2,700 foot elevation climb in 7 miles at an average gradient of over 7%). I was pulling a 10,000# trailer. In the past, my truck has seen excursions over 1,350 degrees on this climb. I have a Smarty set on level 3.

This kit really drops drive pressure and did exactly what I needed. It sounds amazing!! Nice whistle at idle and allowed me to add more top end fueling without high egt.
