EklipzGSXkid: I will let you know man! I am in no rush for them, since I still will have to buy slicks for them, and thats gonna run like another ~800
knochgoon24: Hey man that VGT stuff sounds pretty neat. but you have to keep in mind with these engines they can handle a lot of power in stock form, however it is really the torque that kills the stock motor. So to me I would want a decent amount of lag so my power band can be higher up in the Rs. I have been running an hx35 on my talon at 33psi for over 3 years now on a bone stock bottom end, (Just ARPs, Cams, Springs/Retainers). My set up is surprisingly laggy but I feel like because I am not making a **** ton of torque down low and its all top end power it has helped my car stay together for all this time. I am planning on switching to the T3 70AR Hx40 so I can make more power uptop and sacrifice a little more low end power. With a high HP turbo like the holset, I would be scared to have 30psi by 3000rpm because these motors make peak torque around those RPMs.
Either way, good luck with you Cummins plans! Hopefully it works out, I would do anything to get an opportunity to work at Cummins!
