6.2l detroit question

Anybody ever install a turbo on one? I seen banks has a kit but never heard anything from anyone about them. I know the 6.2 was replaced with a 6.5 turbo for some reason. any info would be greatly appreciated.

Banks Engineering had a kit that would work on a trucks, pickups, and HUMVEE's.

Clearance issues and a lack of volume prevented them from developing a kit for vans and cut-away chassis trucks and buses.

Even the 6.5L turbo presents some challenges when it comes to repair parts. It wasn't a popular option at the time and ever since GM stopped production and the repair parts stream the van/cut-away chassis specific parts are becoming very difficult to discover.

That is not to say you couldn't get a pickup kit and make it work on your bus. It would require changes in the dog house and a few other modifications but it isn't rocket science.

I have a 6.2l as well and was thinking about turning up the fuel delivery through the injection pump screw. I have been reading a lot about it. So, I am in research mode still, to see if it's a good idea. I looked into the turbo idea, but not sure if I want to go that route ($$$)

I owned 5, still own one. All my hot-rodding on those engines involved cramming as much n/a air into the intake WITHOUT using a Banks turbo. Hood scoop, modified filter covers, everything I could do except go with a K&N air filter. The K&N filters let too much dirt pass though and cause scoring in the combustion cylinder for my standards.

Messing with the fuel injection distributor pump is like playing with fire, you WILL get burned. Either the injectors, or other tender parts will get damaged. All you will do is push through fuel that won't get burned anyways because there isn't enough air to burn the extra fuel.

In a nutshell, those are my experiences with the 6.2L GM diesel. I've had friends that put on a Banks, watched as their fuel economy went into the toilet without any significant surge in power. Were they faster than mine? Yes. Was it worth the money they spent? They thought not. I reliably got 21 to 23 mpg with my three M1009's, 16 to 18 mpg with the M1010, and 15 to 17 mpg with my M1031 that I still have.

Just my thoughts.....

I'm not a user of K&N, either. On anything.
