can someone who actually knows for certain if the 4.2 is direct inject?
well i assume the factory TD is direct, the DX is indirect
can some one verify.

The compression ratio stays the same regardless.
If you want to run the Turbo at a high pressure to get more air into the combustion chambers(which is the whole idea of a turbo), you reduce the compression ration to alow more space between the cyclinder head and the top of the piston at TDC to force more air in.
High boost with a N/A compression ratio will result in failure in time.
With the TD 42 engine, it is engineered to be very under stressed to some 20 or 30% from what i ahve read.
This being the case the, the standard engine can handle up to around 18PSI easily before problems arise.
