Does anyone know the part number for a Borg Warner turbo that is comparable to a Stage 1 PDI turbo. I have a 3406C Cat (3ZJ16402), screws cranked all but all the way out, makes in the neighborhood of 550 as it is. My PDI turbo is staring to lose a little bit of oil into the exhaust side and i am looking for a Borg Warner to replace it with. I do not want to use a Holset as that opens up a can of worms I don't want any parts of. I need more than the stock replacement, i get very little smoke with the setup i have now and would like to keep itty that way. Any help would be greatly appreciated.
