I have a brand new hx40. My truck is an 03 ho auto with a banks exhaust and it's got a TST, I keep it on 4-4. I was thinking of using this turbo. What kinds of reliability problems does it have? The way I see it, if the tiny stock turbo holds up, why won't this one? It's from a ISC 8. 3 engine and they hold up good on it. I checked the dimensions of it against the stock turbo and it seems it would be rather easy to bolt on, I also have the intake adapter and clamp. Give me your expert thoughts guys. Thanks.
