The turbo does amazing things to the diesel engine. Installation is really very simple if you get the entire kit with the exhaust included. The hardest part for a stock 6.2 conversion in my opinion will be getting the set screw out of the block for the pressurized oil feed. Everything else is just plug and play with pretty good instructions from Banks.
I would suggest a new Delphi lift pump gets installed when you remove the pump to put the turbo oil drain plate on.
Any of the 1994 to 2000 GM 6.5 turbo trucks and Suburbans have the GM version of the turbo set up. Those can be pieced together for a lot less money. But, exhaust down pipe, cross over pipe and a few other things will have to be thought out and figured out by you. The Banks system was designed for a Square body 6.2 and it just plain fits. The GM units aren't it shows.
