replace a 14.1 detriot turbo with one from a 12.7 the old style turbo..

The racing idea is interesting, but probably needs to be on another site

 

it does work however you're leaving out a couple important parts of the modification. First you also need to have the EGR code deleted from the ECM and this modification cost about $4K

 

Ok. According to the EPA themselves.... http://www.epa.gov/otaq/highway-diesel/workshop/420f04022.pdf .... specifies the useful life of a heavy diesel on road engine for emission compliance. Once the engine meets these requirements, it no longer is required full compliance with the clean air emission standards of the particular engine. So, if the engine has met these conditions, you can modify it to your heart's content as it no longer falls under EPA emissions compliance guidelines. So the first EGR equipped engines should be either outside the life expectancy, or darn close, and then they are fair game for fiddling with.


(iii) For heavy heavy-duty diesel engines, for carbon monoxide, particulate, and oxides of
nitrogen plus non-methane hydrocarbon emissions standards, a period of use of 10 years or
435,000 miles, or 22,000 hours, whichever first occurs, except as provided in paragraphs (4)(iv)
and (4)(v) of this definition.

(iv) The useful life limit of 22,000 hours in paragraph (4)(iii) of this definition is effective as a
limit to the useful life only when an accurate hours meter is provided by the manufacturer with
the engine and only when such hours meter can reasonably be expected to operate properly over
the useful life of the engine.

(v) For an individual engine, if the useful life hours limit of 22,000 hours is reached before the
engine reaches 10 years or 100,000 miles, the useful life shall become 10 years or 100,000 miles,
whichever occurs first, as required under Clean Air Act section 202(d).

 

100k miles??? That's basically 1yr of driving. #### near most trucks meet that requirement lol. ...not to be confused with that 435k limit

 

Admin's post, through the link I posted, seems pretty clear, doesn't make exceptions for EPA limits. Perhaps they'd like to edit their original post or step in here to clarify what's allowed. If you find good information here, I'd encourage you to save it separately in case somebody deletes that post or the entire thread.

ETA. Where does it say that you are allowed to modify the emissions systems on engines past their EPA determined "useful life"? Not saying it doesn't, I just don't see it in the link provided. Would be good information to have when an officer questions your legal modifications.

 

Yeah, you're confused. Seemed clear to me. 10year/100,000 miles or 22,000 hours. If the 22,000 hrs is met before 10 yrs, then the 10 yr rule overrides.

 

Is the turbo a direct fit and does both oil lines bolt on?
