They sell a kit. Call them...supposed to be nice fellas
I can't say personally tho.

 

I spoke with them the other day about the DIY D66. $650. seemed pleasant enough and helpful

 

Yea, James is a good guy.

 

is it necessary to change the injector cups when doing injectors?

 

no it is not necessary to do the cups when you do the injectors.

 

just a quick update, I ended up settling on stage 2s, 160/80 from rosewood. I also did T-500, E-Fuel from Bar None, intercooler from a 6.0, and s366 turbo and then tied it all together with Gearhead tunes on a hydra chip. All I can say is wow! It is a whole new truck. I haven't towed with it yet but so far it has run very strong and cool. I'll update once I do some towing through the mountains. That will be the true test. So far I am super impressed though. I should have done it a long time ago!

 

Crap, you've been busy.

 

You did a s366 or d66 ? I thought you were talking about the border d66?
I bet you HAVE been busy.heck I have been working on mine for like 5years lol

 

yup I sure have been busy! I've been wrenching all day, every day for the last week or so. Had to get her ready to drive across country in a couple weeks. And yes, I settled on the S366. There were too many mixed reviews on the D66. I'm sure it would be better than stock but I couldn't decide if it was worth it. Plus, the T4 setup will give me a lot more options in the future.

 

Where's the pictures

 

I'm so bad about taking pictures as I go... I will snap some of the engine bay and see if I can figure out how to post them... haha

 

don't worry. I always think about it after I do the job too.

 

I'm glad you settled on stage 2's. Despite what some may think, the larger nozzle can definitely run cooler EGTs if the tuning is correct. That setup should be making 440-460hp. Glad you're happy with it.

Since Darin will almost inevitably come and argue this, I will say that there are many cases where the larger nozzle can be hotter and I believe this to be due to inaccurate tuning and/or less injector pulsewidth. I did notice lower EGTs per the amount of power with larger nozzles in my SD. I also noticed higher EGTs in my OBS with larger nozzles and the stock turbo. Without going into too much detail, a 160/stock and 160/80 injector flows the same amount of fuel. Neither injector is capable of any more than 160cc. The larger nozzle can just empty that fuel quicker. Tuning still dictates how long the injector sprays fuel, how much ICP it runs, and therefore how much fuel quantity is sprayed each revolution. IMO the two injectors when being asked to spray the same quantity of fuel in attempt to make the same amount of power, the larger nozzle can make that power at less EGTs due to the reduced injector pulsewidth required to get the job done therefore requiring less timing advance at higher RPMs to be able to get all the fuel into the cylinder. This would allow a tuner to potentially be more accurate with the tuning by being able to start injection and stop injection exactly when it needs to.

 

That's interesting Travis. Now the hard part is finding a tuner that can make it all work without live tuning.

 

So why can't Glenn get his EGTs down? Do you think the live tuning will solve his problem?
