HaabHauling Posted Thursday at 05:26 PM Share Posted Thursday at 05:26 PM For a 1991 RD688s does the turbo number S3A038 and 631GC5127AM22 sound correct? I'm finding this turbo belongs on a 250hp motor. Is there any other turbo you would use on a non turned up e7-350? Please provide part numbers if at all possible. I'm having trouble finding the turbo listed above. It's moderately pushing oil. Thank you in advance!
