That's gonna be a hard one to get, and I'm not cutting up my spare 8 for ya

What exactly is it that you want the pic for? I know em inside and out, I just don't have any exploded or cross sectionals.

WAIT! I lied... I JUST found something on google.

Now... Other then the fact that it's in German, and it's not a Gm-8 (RHC6) This is an RHB6, Both are made by IHI, and they are built very similar, except the RHB6 doesn't flow as much air.

See, same family tree, just the baby compaired to the 4rd largest lol.

The major difference is when they switched from the wastegate in the housing, as seen in the pic below, in the gm-4 and went to the wastegate in the turbine outlet elbow for the Gm-8.

98 3/4ton 4x4 RC LB F vin L65 HO.
DSG gear set, gurdle and oil cooler, ported and half assed polished heads, HE351VE turbo, 3" downpipe, 2.25" xover, 3.5" DNA muffler and a 4" weed burner exhaust, NRK High idle switch kit and K47 relocated intake & AEM filter, Royal Purple in the trans, engine, and rear diff, 4 cobalt gauges, boost, pyro, trans temp and drive pressure. -6 CAT fuel system, Carter fuel pump. Sitting high on 35" Duratracs.
Bought it with a pooched engine and rebuilt it myself! 211,000 kms on the truck, 110,000km on the rebuild, still chuggin and still screamin.
If you're not drivin it hard, you don't deserve to drive it!
