[QUOTE="Nadra, post: 16010420, member: 96452"] First...wow. This was tough to read. I can't imagine being in your shoes. Like some others have already said...I thought I had the crappiest luck around ...until I read about this abortion of a car. Moving on...Some thoughts on your 2.2 KB: this is the blower that is on my car and has been for the last 12 years. Some who are saying you are spinning the rotor pack outside of its originally designed operating range are both right...and wrong. Generally speaking, at ~18K rpm, you are already over what KB recommends. However, it is fairly common knowledge that they also built plenty of 'buffer' into this. While technically outside of their advertised 'efficiency' range, they will perform just fine at speeds upwards of 20k rpm. Look no further than the tried and true combination of a 3.1 upper/4 lb lower. This already has the blower operating just over 18k @ 6500 rpm yet there are countless combos like this still working just fine. Swap that upper to a 2.76, and you are now just north of 20k rpm....which is also a combination routinely used especially when switching over to e85. So the question isn't so much whether or not you are over working the blower as it is are you able to effectively remove the heat it produces because with the added boost comes added heat. If you are able to remove the heat and keep IAT2's in check, the KB won't be an issue. Too many have done this as proof....myself being one of them. Your problem, at least one of them, is running pump no lead (91-93, doesn't matter, both junk fuel for these cars and that's at much lower boost levels than you are running). If you are already at 20-22 psi, it's astonishing you haven't already wiped out a ring land or worse. I did that only much much lower mileage. I would tread lightly on your current combo... ;) All that said....KB uses an Opcon case and there ARE problems with the original OEM design. I had mine rebuilt at PSE when I went thru the engine back in 2015. They addressed some common problems and corrected them, one of which is the tendency of the rear of the rotor back to move and start grinding into the rear housing. But believe me, I know this is just one of many things you have to consider with this car you have. Best of luck to you. [/QUOTE]
