Just my .02
I just finished installing the upgrade, I went with the PM102 (China) and an autozone heater core. The diameter of the pm102 was larger, no doubt. I figured that in itself was enough for me because my blower motor on high is about as crappy a you could get. I used an air saw and cut out 1/4 in all the way around the opening, then stretched the original foam seal around the new motor.
It certainly moves more air than I thought possible!! I just drove around and was plenty comfortable on speed selection 2..up all the way it sounds like a 747, so unless I need to really defrost the heck outta something #2 is fine!
I would recommend this upgrade for sure, and to add to the posts in here, there are a total of 4 bolts (nuts) you have to get from the firewall on the engine side. and when you cut the new hole, make sure to cut a little extra up and towards the passenger side, the bolt restricted me from going in and the sleeve on the motor wouldn't let the unit come up...A perfect catch 22! I was able to pry the motor out a little using the sleeve, and pushed the unit up at the same time. It "popped" into place and held just fine, however if I was going to do it again, I would have trimmed that up so I wouldn't have to be a contortionist next time!!!
All and all, I love it. Chinese crap and all, it works for me.
