Legality of swaps, just talked to state emissions guy
Found the number for my state's diesel emissions program, and gave him a call. Real nice guy actually, helpful, and very willing and able to answer lots of questions. Reinforced what Ive always known on gassers, applies to diesel, plus one or 2 things as well.
Same year or newer
same technology or newer
same classification of vehicle
-no diesel swaps in jeeps, 1/2 ton anything, unless youre using a 1/2t diesel engine ie liberty, 2lt etc
-no truck motors in cars, but can put car motors in trucks (at least in my state)
-12v swaps, nothing computer controlled. So no 95+ (electronic inj) fords are legit with a 12v.
-150 body on 250 chassis with diesel, not ok, vin and emissions goes off the body
Everything must also function correctly. Check engine light proper function, along with some things in the computer that they look at, that tells them the ecm/pcm is monitoring those functions as well.
Just wanted to let folks know. In case you are looking at a swap, and want to be legit.
Interesting point, EPA technically applies to everything. So a motor that was emissions controlled, but now in an offroad only application, still needs all original emissions equipment to be completely legal. Its not really enforced, but it is the law.
