does anyone know anything about the h2c holset it came on my 4bt recon from cummins cpl857 I was seeing 30 pounds of boost, I swaped to a hx35 with plugged wast gate and now have higher exhaust temps with same boost numbers the hx has a 12 cm housing I can not figure out what the h2c has, but it does have the small compressor like the h1c
