I got an 03 rcsb with a 4.8 @ 138k miles. Got a friend that's got a bolt on turbo kit for my truck. It's a Garrett 55mm bottom mount turbo. Comes with everything he said and comes with an edge tuner tuned for a turbo. Problem is I have pretty much a stock truck. Got wheels exhaust intake etc. just wondering on how hard it would be on the rear end and tranny. What could make it hold 350-400whp with no problem. He said it runs at 15 psi. I myself have never heard of that small of a turbo on a truck unless they're twin but I'm wondering what you guys think. Any tips would be great.

I wouldn't expect that to last long. Start saving up. The rear end might last longer than the trany, but depends on how hard and much you beat on them.
