can u take 6.5 injector pump and injector and put in a 6.2 will u gain or dont mess with i have to get pump and i was going to do injectors to do the right way

The mechanical 6.5L IP and injectors will work fine, the 6.2L inj. lines will need to be slightly tweaked as the 6.5LTD inj. have a shorter body. Without a turbo, the pump will very likely need to be turned down if it was calibrated for the turbocharged engine.

no turbo at this time i have to get new pump and inj. so i was thinking if i got 6.5 pump and inj would the truck gain more power its a 1985 6.2

Hi,

Switching to a 6.5 pump/injectors without an increase in air will give you higher EGT's, which will force you to lower your fuel rate. Going to a higher pressure (6.5 system), will reduce injector noise, besides the obvious of putting a shorter burst of fuel in the cylinders.

If you intend to turbo the truck in the near future, then the 6.5 pump/injectors would save you from doing the r/r procedure twice.

I noticed a drop of 2-3 mpg when I switched to a 6.5 system. I added a banks turbo at the same time. More than likely, the drop is because I now enoy the monster under the hood...

More air will need to be drawn into the engine to get more power. A free flowing exhaust and intake will be required.

Here's one idea for a better intake: 6.2 intake kit (http://forum.thedieselpage.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=2;t=002272).

Dr. Lee devised a double stack air cleaner box and header adaptors for more flow - do a search for his posts for more info.

[/QB]I've tried to find info on how he made his very nice double stack (think I saw somewhere, it uses a pair of Olds 442 elements) cold air system . . . I'm guessing it disapeared . . . :(
