Ported heads on a stock turbo truck I wouldn't think would get you much of anything being its forced induction. Still don't really see why bigger injectors are such a big deal?? I guess other than the reason most won't do them. Your still restricted with air flow with a stock turbo. As long as the the turbo remains stock and everything inside the motor(camshaft) remains stock then really everthing else is bolt ons. Here's the thing, is everyone going to be honest? I mean Tom could have been quiet about his build and no one would have known he had bigger injectors. Then could have said his old motor was really tired and the fresh one runs that much better lol.

The only legitimate complaint I can see anyone raise about Tom's motor is the pistons aren't stock anymore.

you would probably be surprised, getting more flow will add power and dropping boost while maintaining flow will add power because the air will be cooler having not been compressed as much and there will be less wasted energy driving the turbine wheel to create bigger boost.

basically what I'm saying is even if the flow stays the same because the turbo is incapable of any more flow ( which I doubt) there will be a gain.

You could look at it this way,

Does adding up-pipes make it not stock ?

Does a ported turbo mouth make it non-stock ?

Does adding a modified turbo compressor wheel make it non-stock ?

Does adding sticks without dual fuelers make it non-stock ?

Does stripping it for weight reduction make it non-stock ?

Stock could be viewed any number of ways ??

Glass is either half empty or half full, it depends on how you look at the glass, the water level didn't change !

Trent cut the shit already... LLY's have always been the most feared with our smaller induction system, smaller injectors, and even our random goofy defueling issues

My opinion which means nothing IS :


If the title or competition is labeled as stock then STOCK it is. Since we aren't discussing stock trucks as rolled off the assembly line then the discussion or subject is tuning. Correct?

The ONLY allowable changes would be exhaust and PRE turbo air intake modifications and a lift pump period. Weight reduction is foolish to discuss as some people are tall, some short, some skinny, some fat.

If you have made any INTERNAL modifications to your engine then it no longer stock and that would include injectors,turbos ,porting ,polishing,de-lipping pistons ,etc etc etc.

Otherwise your running a modified Duramax not a stock Duramax. So they should be in a class of their own. So have a slightly modified list with what is allowed.

It Is What It Is!

I don't have a truck in this discussion either but I agree with Mackin, you are either pregnant or you are not, can't be just a little. You guys had intake, exhaust, built tranny (Allison only), lift pump, modded regulator,tuning, suspension and tires. That looked pretty good to me. FWIW
