Re: The D4D Death Shudder
Your reasoning behind this is actually slightly flawed. The compression ratio does not directly depict the combustion pressures when you are talking about a turbocharged vehicle. The 1KZ-TE doesn't run as much boost as 1KD-TE engine. Part of the reason for the lower compression ratio is the 1KD-TE has better off boost driveability and comes onto boost earlier. Toyota actually have a reputation for severaly over engineering their engines - shame they couldn't do this with their gear boxes :x . The engine fault of a metled piston is more logically due to a failed inejector or lack of fuel delivery (leaning), not cheaper engine components.
