yeah the stock turbo in 03-04 was the he341 and from then on to 07.5 it was the he351, i bet with just an he351 your exhaust temp drops a bit though, specs on an he351 is around a 60/60/9 whereas an hx35 is like a 57/60/9 i think a nice he351 and s400 setup would be awesome, I don't like to do this but ats makes a kit that would work very well for towing it's a stock he351 over an Aurora 4000 so both turbos are a good single turbo, but with the stocker over the 4000 it'll spool really fast, literally instantly and you can run it on a stock fuel system and be just fine with it

how much does that kit run? your lookin at 1200 bucks maximum if you do the piping yourself and run the hx... prolly around 1500 with the 351. i dont know if money is a factor or not, just something to compare

I actually think im gonna grab a used he351 for now, throw it on and see what happens.
And then if Im still not happy get a second one.. seems theres a lot to choose from. Ill keep you guys posted...
thx a LOT for the help :)

finally is there any differences in the he351s from the diff years? Im aware the electronic wastegate controller will either need to be plugged or tie the wires out of the way..

only difference in 351's i think is theres the he351 and then theres the he351ve off the newer trucks which is the variable vein ones i believe and you would need the controller from fleece to run it.

I'm pretty happy with my phat shaft 62/80. Spools quick, plenty of boost and my egt's have never seen more than 1350 pulling a 32 ft gooseneck at full throttle. Just my 2¢.... :tttt:
