Last year my son was driving my 91 Jetta with AAZ 1.9TD when deciding to ford a gully washer - well he found out that water is not too compressible in comparison to metal engine rods. Now with newer rods/pistons and rings I am not seeing any boost out of the K14 that was on it when he crossed that bridge. So I was just wondering if ingested water through turbo into intake usually messes turbos up or not? Where is a good place to buy and or have one rebuilt? Or does anyone have a good used one for sale? Like I would think I would want a T2 or K14, I am assuming the T3 would be then next larger in that series but what about the K14 and up? Which would you recommend for this engine? One reason I really think that my turbo is shot is that I have taken the turbo's intake and exhaust hoses off and yes turbo is spinning but when revving up engine it won't suck in a piece of cardboard in held close to the inlet and there is hardly any felt boost from its outlet???
