That might not get people to help you.

Turbo big block is pretty fly. Should be the best of both worlds. Those that do it seem to have EGT's in the basement, I'm guessing because they have not upped the fueling rate? One would presume you can go a lot more fuel than where you are at now (lower button #?)? Nice job, regardless...

Understood. Looks like you could up the fuel even more then if you wanted?

Does the stock Cummins 250 PT pump has a provision to add fuel under boost? I would guess not, and you are just pouring more fuel in?

Nice tune. EGT actually seems a pinch cool?

Spot on. Found it. Looks like maybe try a historical way or apply as a business with less than 3 trucks, or keep it registered out of state, or...? https://www.arb.ca.gov/msprog/onrdiesel/onrdiesel.htm So, about that 250 turbo power up....

It will pass the laws of the emission generation it was manufactured. In my case, it will be a 2005 engine, in a 1990 truck. But, I think emission laws are based off the vehicle mfg date, and not the engine? Interesting case though. If for some reason your area requires a sniffer test, then...

Swap out the old dinosaur engine with something more modern. It can be done cheaper than you think. I am doing it to my M925a2. I just bought a 24 valve common rail Cummins ISL motorhome engine for a song, much less than what people here spend trying to hop theirs up and then battle smoke and...

Pop-Rocks in the fuel tank provides for some good entertainment. Love the You Tube commenter that said "That was knarly, do it again!".

That's good enough reason right there! Anything with a spooling turbo sounds like it is going to rip the guts out of whatever it is hooked to. 300F is a fabulous drop, that sounds like in increase in reliability to me... It will help to prevent this (advance to 2:03 for the fabulously funny...

Yes, I'm 2 pages late. It is natural to want more and proceed that path. Keep in mind these trucks were designed and built via lowest bid contract to meet specific performance requirements, which they did. They were not built with the intent to be personally appealing as race cars after their...
