TURBO HELP
Need some advise. I hav a 92.5 f-250 7.3 auto trans. Turbo going out(bearings) turbo is a Garrett redone by Roto Master out of Canada. They no longer do smaller turbos only big stuff. Question is I have access to a new garrett turbo that was orig intended for a 91 international DT-466 220 hp. cold side is same configureation as the other one just a hair bigger caseing. Would need to change flange on my down tube but not a big prob. Only concern is to much boost but don't no for sure should be close. Anyone got any thoughts as to if this would work or not??? Any input would be greatley appriciated Thank.

Depends on the wheels and housing sizes...
If your just looking to get your truck on the road, skip the fab and just find a used turbo or have yours rebuilt...
If you want to explore options, and dont care if it requires a little extra work, look into the turbo itself and see how it maps out compared to your engine combo... Like Russ said though, its more than likely a shade too big on the housings, those engines were meant for large trucks with lots of weight, and needed free flowing housings, spool-up really isnt an issue in that sort of setup.

Hey Im looking for a turbo for my 7.3 project that will go in a 20,000lb MH. I want mine to be free flowing and laggy. I will be running more fuel than stock and will be using a J2 cam so I will be pushing more air through it to help spooling. I am looking for about 15 to 20 psi. I just don't want the high EGT's of a fast spooling turbo. If you have the map on that turbo please put up the model number of the turbo so I can use the info for comparison. I plan to run water injection for the long pulls on the hills just as insurance. Everybody seems to look for fast spooling turbo's so getting info on somthing "not" so quick is hard to figure out.
