The main thing that you should know... The stock turbo will fail much sooner than an appropriate turbo. Overspeeding and continuous high heat are the culprits. I was able to get 70 hours out of my stock (2nd gen single) turbo. That was mostly light duty turbo normalizing. I don't think anyone else even got that many hours out of the stock turbo. The twin stock turbos are particularly not suited for aircraft use because of smaller size. The twin system is meant to minimize turbo lag, not provide optimium performance.
I am now using most of the stock components: manifold, exhaust housing, oil and water fittings. But the innards of the turbo are very different.
Big and open are important aspects for the hot side of the turbo.

Steve, Dave, or anyone else using the stock turbo(s)
On my 20B installation I am considering using the stock turbo system. I would only be using low boost levels. I have a couple of questions for anyone who is using the stock turbos. Were your systems twins turbos? Did you leave both turbos in place? Is over speeding an issue for our mode of operation? What else should I know about using the stock turbos?
Thanks,
Joe
