That looks great, I want one so bad!
So, any notable differences between the old and new Gturbo's?
My 2 were very similar, but had a few minor differences in appearance, but the 1st one was much louder and whistled hard, and the new one is very quiet, and I don't think hits quite as hard as the original while it lasted (maybe related?).
Your original Gturbo was MUCH older than the new one, so I'm curious to hear your observations.
My new one has a black wastegate as well, while the 1st one and the replacement wastegate they sent me were shiny metal finish, so there was a revision of some sort. Both had green impeller wheels, and the housings all looked the same.
Here's the table that Gturbo lists. I would bet my rig is on the low end of the spectrum for a Grunter. Still, it feels like night and day difference. I can easily cruise at 80 mph and don't slow down on hills. Towing my 5000 lb boat/trailer seemed natural as well. Back when I got the cruiser, my EGTs were higher than they are now and every hill felt like I had to almost floor it to keep speed. Another benefit now is that I can take hills using only 10psi of boost and keep speed. There is a lot more usable power in there.I wonder what the HP/TQ gains are from stock with you essentially being full bolt-on now.

Wow, my experience is almost identical to yours. My new turbo is almost silent and my old one had a (satisfying) turbo whistle to it. Also, when boost hit on my old one, it hit almost all at once and it felt like it hit hard. My new one gets into boost much earlier and gives me power in partial boost way better than the old one. But, at max boost, the old one felt a tad perkier than the new one. That's why I'm considering turning the boost up just a bit... maybe 24 psi. I wonder if they changed springs in the wastegate... maybe to a spring that has more of a progressive spring rate? (maybe the older version was more linear?)
What boost are you running right now? Long term would you see bumping boost up to 24psi to be an issue? (it seems higher than most folks run on here)
I tell myself that I'll bump up the boost after Vermont Overland. But, I'll have my wrenches with me. So, we'll see how that ends up...I'm currently running 20-22psi, probably the max I should be without an intercooler. You do have an intercooler, I would have no reservations about running 24psi on your setup.
Haha you’re not overpacked you still have the 3rd row seats installed! Great work!
Why would those 3rd row seats not have come out and went straight into storage when you 1st got that truck back home after purchasing?!? I mean, unless you use them, they are a complete waste of space back there and dead weight.
Man, the truck ran awesome. Spool came in earlier, EGTs were a little cooler, power was up. I still haven't turned the boost up but I might do that today. Also, the new intake had a place for the vent hose of the head. So, we routed the hose, post intake filter, into the intake stream. I want to either get a catch can or just vent that down to the frame again.But how did the truck run?!?
