Had a weird idea...(6.2 turbo)

    Think a stock 6.2 could handle the boost from a stock import turbo? I'm pretty sure it could, but I think the exhaust temperature would melt the impeller in it. Whatcha think?

    I'm not an expert by any means (my turbo is a '87 Shelby Lancer - someday rice spanker), but I don't think an import turbo would make enough boost for our engines. I just don't think they're big enough. Maybe if you ran a twin turbo set-up... hmmmmmm

    A single import turbo wouldn't make enough boost. Most of the import ones only make 6-10 psi on a 2 or 3 liter engine. You need to make 10 psi on a 6.2 or 6.5 liter engine. The next option is dual turbos, you could then probably make some acceptable numbers.

    Sorry, forgot this part. All turbo impellers are steel, you don't have to worry about melting it like the aluminum pistons.

    So you're saying this could possibly work?

    Sorry, but are you referring to the pistons in an import, or the diesel?

    You don't have to worry about melting the turbo because it was from an Import. The impeller in the turbo is steel, you would melt the pistons in your engine before you melted the turbo. But yes, it could work, but i think a single turbo wouldn't make enough boost.

    Think I should try this or just buy an aftermarket turbo for a diesel?

    Depends on your ability. If you fab your own then you need to make the exhaust mounting and intake runners etc. If you simply purchase it then it all comes in a kit and you pretty much bolt it on. I like to fab stuff, if I had access to a couple import turbos that I knew were good I would build it myself.

    Id just buy after market, at least you know its going to work. Unless you have the stuff lying around you can experiment with.

    I don't even have the engine yet. Imports are big around here, and everyone is ditching their stock turbo's, if they have one. The truck isn't built either, so I can pretty much do what I want right now.

    Just a couple of ideas. 1. A turbo from a Buick GN. 2. A turbo from a Cummings or a Powerstroke.
    I think the GN turbo would be on the the small side, I had one and it looks smaller than a Powerstroke turbo. No evidence though, just guessing.

    I do not think that the turbo would make enought CFM for a 6.5 l diesel.
