I'm looking for a small turbo to put on my 1.6l na diesel to improve gas mileage. Under full throttle, from 1.5k-4k rpm it makes ~50-70 ft/lbs, and I was hoping for something that'll give me ~10-12psi under these conditions with boost off idle. Hopefully something that's kinda common at junkyards (mopar turbo), but if not I can always watch ebay.
