HX40 turbo?
#12
I'm just here to ask a question about my son's truck, mines a '99, he has a '94 and put an hx35 on it(among many other things). I think you'll like it much better and it'll last a lot longer. As said above, you can always give her a bigger set of teeth if you want, or save up for the phat shaft price tag. By the way, watch your boost level unless you've already replaced your headbolts with studs.

Oh yeah, I think I know his problem, but I'd like more opinions. After he put 100+ hp injectors in it he started having a problem where it will run fine at low rpms but starves for fuel as the rpms climb, unless you really romp on it then it'll run it's *** off. I'm thinkin the lift pump, he never changed it. His main pump on the lower engine went bad and he put a sweet elec. pump on that I could water the cattle with, so he's got ample fuel pressure there. Again it's a '94 12v 5.9 Dodge Cummins 3500 Dually. Can you bypass the lift pump? It seems to me someone told him he could, if I'm thinking right.
Thanks for any help!

hx35 is stock. right? but ether way i dont seee the hx35 buildin enough boost to blow ur head! You will blow the turbo before the head goes. As for the fuel starvin have the pump timed. That should help. mine helped alot wen i first started buildin. as for phat shaft yukky yukky yukky. I hate phat shaft. hx40w2= 64 or a 66 mm u can get them on dieselsite.com for $340 with next day delivery.

i could get 45psi out of my stock hx35, isnt the stock head at its limit at 40psi??? and on the 94 it could have had a h1c and he upgraded to a hx35-chokenonmismoke
dave59- get your son to advance his timing since he is running the bigger injectors it will help out alot with top end fueling and make it run alot better, also he could put in a set of 3k gsk (if he doesnt already have them) and it fuel really good all the way to 3000rpm
has for the hx 40, i have one on my truck but i found it laying around the shop and put it together with the 14cm exhaust housing for 100bux, it was a great upgrade over my stock turbo but if i was going to spend alot of money on it, i would just save up and go with a really good one
