6.2 vs 6.5 Injectors

[gsimpson]

This may be a dumb question but do 6.2 injectors have a higher pop rating due to compression(21.3 to 1) being higher than a 6.5 injector (18.1 to 1) compression rate.

Not a dumb question. The "18:1" compression 6.5TD is an aftermarket thing, not OEM in light trucks. 6.2L and 6.5L stock compression is similar. The 6.5TD injectors have a higher pop pressure than 6.2L and 6.5L N/A injectors. Variations of this in OEM form has been very minimal over the years.

Basic math tells me the 6.5 ones are at least .3 better.
