I was hoping to get a little help with a Q here... I'm looking to buy a Turbo on the board "GT6152-S turbo. 4” in, 2.5” out. Precision .63 exhaust housing. It has approximately 1500 miles since new, but was on an engine that developed a rod knock, so it may or may not need a rebuild. It has no thrust play, but there is a bit of radial play". If I put this on my car to run untill it needs a rebuild if not now could it cause any damage to my engine? I figure for the price I can run it till it would need a rebuild just dont want to hurt my engine doing so.
