Now your talkin Baby !!!! Go Cummins !!!!!!

 

Hi, I have a 2wd 1990 F250 7.3L diesel with 215,000 miles. I just straight piped it to a 6" miter stack and i would really like it to roll a little black without damaging my pistons at all. Does my truck have a torque screw like the 6.9's? or is there something different that i have to do? please get back to me and let me know. Thanks.

 

u were in the right place with your previous post. turning up the fuel will cause little more smoke. just dont go crazy with it, u will melt down the motor.

also do a search on turning up the fuel, many posts about it. if ur out for just smoke, get a cummins.

 

i got mine turned up and just right not to much smoke but still smokes i turned 6 flats about the damn oil line went out that goes to the turbo i just but a high pressured water line on it its doing ok once i get it to stop leaking and noticed my damn manifold is cracked

 

i have a 94 7.3l idi and it has a blown head can i put turbo heads on a non turbo system some body told me that i could

 

Will make comp. Ratio different ..... The combustion chamber is in the head unlike most other diesel engines where the piston bas a large bowl in the piston and those heads are flat ... like a cummins .... not too sure what the comp ratio would be but the turbo would ah a slighly lower compression ratio to make room for boost .... where the NA would have a 21.5:1 comp. Ration ... turbo would have 20.5:1 i beleive .... should be realclose to that ..... Diesel crawler has the exact numbers if i recall right
