I was wondering if there is anyone out there who could give me advice on my current Hilux problem: I have a 1993 3L Diesel Hilux, with a turbo added. As I was driving I heard a knock, followed by a loud ghostly noise that changed it’s pitch along with the sound of the turbo. Upon inspection from a mechanic, he showed me the turbo’s impeller was quite badly smashed up, as if a rock or nut had gone through it.
The first and more preferable option (if it didn’t cost so much), would be to take it to a mechanic and have them fix it. I would tie this trip in with a replacement of the head gasket.
Secondly, the turbo- although retro-fitted- is stamped with a Toyota logo, so I assume it is off a surf or similar. Does anyone have any advice on swapping it or the impeller for a second hand one?
And the final option is I find a stock intake manifold and return the motor to normal aspiration. Can anyone give me experience regarding top cruising speed, economy, and torque on normally aspirated 3L diesels? I spoke to someone who said his cruises at 105kmh easily, whereas mine doesn’t really like going above 95kmh.
Thanks everyone for your help.
