Personally I'm not a fan of the Lysholm/Autorotors due to the bad design of the boosted TB, or the expensive "hush kit" to have it setup as it's supposed to.  I'd also wait for a reply from Duffman as he has the inside scoop on all things BBM.

oh, and I edited another option to your poll 

i had bbm do an oe rebuild and a stage 4 port and so far am happy with it, although i have not really driven it much at all yet.

i helped a friend build a turbo set up a long time ago... in fact he then spun out and went into the woods backwards and i bought the motor, turbo, and everything, rebuilt it and put a xflow head on it that was going in my rabbit.  sold all that and just kept the turbo.  get a TT or SNS(if you can get ahold of them) chip and turbo that pussy.

i could really tell you a lot about the screw compressors....but i'm legally not allowed to. :) i could also tell you about rebuild parts....but again, i'm not allowed to.

screw compressors are more reliable, in the sense of needing rebuilds.

i'm not saying they are connected, but after the silencer kit was released, a lot of chargers came back seized....coincidentally, they were all running silencer kits. john at BBM managed to find other evidence of failure in most of them....i'll leave my personal opinion off of here about that subject.

if you are gonna leave it supercharged, i'd rebuild the charger you have. unless it works out in your favor to buy erics and ship it....either way, you are paying shipping on the damn thing. to rebuild it, you pay it twice. with erics, pending low price, you are paying once. and now you have a backup. how dependable that backup is, though, is questionable.

as for doing it yourself, if you have a press and the slightest mechanical aptitude, you could do it. but w/o one, you are gonna hate life when you go to replace 2 of the 5 bearings (i believe it's 5)...i also remember something about 2 of the seals are incredibly close in size, so mixing them up yeilds in a lot of oil out the exhaust side of the charger...otherwise, i've never rebuilt one and it's been a year and a half since i last watched one get rebuilt....our buddy jason is pretty good at it though. i think he told me one time, he woke up at 6am, had the charger out, disassembled, rebuilt, and reinstalled in time to make it to a gtg meeting spot by 9am that was 20 mins from his house....not to shabby.

but as far as mileage goes, after a rebuild, we used to tell people they would need to send it back in at 60k for another rebuild...we would also tell people that you can really only get 3 rebuilds out of them...sometimes 4....to be blunt, i dont know how much truth there is behind all of it. i would say i trust john at BBM in his research over the years before i worked there to have it backed....but i did work there. that's all i'm saying.

This one already has a tiny pulley on it, but I don't trust it because of the half-assed filter setup he was using. Think I'm going to buy a rebuilt one and send the old one in once I get the replacement.
