12A Turbo Longevity?

So I fixed my 12A's fuel issue by putting a smaller pump on it. Now its boosts pretty good but still has some awkward spots. I boosted a lot tonight, and it was so much fun! I find myself asking how long should a 12AT last when maintenance is kept up with? So all you guys with 12at or even 13B turbos how long are your motors lasting? Still going ? Popped?( if so please explain what you think caused it)

Each motor is different. I can't speak for 12a's but I know that the rew has issues with the water seals.

30-40k for a motor that is properly maintained and is decently modified. There are many factors that can influence this though. Just boost it and have fun.

on low boost they can last over 100,000 miles, as the boost goes up reliability goes down..
