Neighbor has a 1992 W250, 5 speed, stock engine. He had the VE pump rebuilt a couple of years ago and I turned it up a bit. Other than that, it is stock. It has the stock non waste gated turbo and his EGT's can climb when towing. Is there a waste gated turbo that might be better to keep the EGT's in check when pulling hard? HX35 from a second gen?
