i have this 01 911 carrera 996 3.4l with no engine (broken engine) IMS bearing. i got the car with the desassembled engine next to it. i still have the ims but not the bearing. now the guy said that the engine had a single row bearing. i purchased another engine, same car, same year, same engine. both of the blocks were cracked, so i replaced them with the original engine blocks. i think this other engine has the double row ims bearing. i want to upgrade the bearing before i will put the engine back on the car. now if the block use to have the ims with a single row bearing, and now is a double row bearing.... whitch kind of bearing should i buy? it'll work with these blocks? i just tought about it today, and i'm kinda confused.
Thanks for your help !!!

 

Jake at Flat Six Innovation is going to be the guy who can answer this question, hopefully he will chime in.

 

Its simple:
Buy the bearing that fits the IMS that you will be using. You have no other logical choice.
