yes i have a few trucks though once i got to my goal in horsepower it wouldnt be everyday probably wont get 14 mpg in it with all the mods i plan on doin but im thinkin the cheapest rought is buy the s400 turbo theres a 91 mm but thats way to big imo and then theres a 77mm if im thinkin rite for 300 no reserve and for piping maybe a machine shop or votionspeed or extreme psi. i need a good deal on a manifold for twins maybe a used or new under 400. i got a question for u though u seem to know alot with my pump turned up runnin a no plate have it adjusted for it by mcn diesel then 140 hp injectors sdx custom dv's twin turbo's ( stock hx35/s400) and 60lb valve springs 4 gsk kit afc springs and a ram air aftermarket all set rite with the rite timing and a 5 speed with a 700 hp or better clutch wat is a rough guesstimate of hp range i will see

That hx35 is not really compatible with serious horsepower. You should get a htb2 for on top (don't think you're goin to get one off of ebay for $300)and a 3b or s400 for the bottom. This winter I'm goin to change to a s362/s475 combo with SDX 5 x 14s. Should be good for around 600 hp, maybe a little more depending on how well I can tune it.

the detroit allison came in it stock its on the paper when the first owner bought it the paper that tells u wat it came with a detroit allison 4speed with overdrive and i know a little bit for 18 years old on a diesel truck i just dont understand which turbo's to run with eachother for twins or the best match im swappin it to a nv4500 i want to sell the automatic

i would love to have combos like that but im only 18 and mow yards and pay my own bills so money is keepin me from a 3000 dollar setup. i believe u on the hx35 but thats all i can do rite now and run a s400 b2 with it. it may smoke bad but its better than one turbo plus imo if i made the hx35 a hybrid it would hold up better im shootin for 700 hp if i need bigger injectors and delivery valves than 140hp and sdx custom dv's let me know plus ill be runnin a no plate and have my pump turned up to make 200 hp on top of 180 so 380hp just the pump and no plate with no other mods is wat i was promised for 450 dollars with dyno or 300 no flow bench or dyno. i might sound stupid but im tryin to explain it one day ill be smartER

First lesson advertised horsepower of performance products added together does not a good running truck make.

i understand that i was just wantin a rough guesstimate im no diesel tech or anything close so i wouldnt have known that my bad. i guess ill just have to spend a few k's in the motor and put it on a dyno but all that should roll the smoke out shouldnt it

Once over the the 450-500 mark a ppump powered engine gets hot and smokey regardless. Gotta love static timing or better yet retarded timing.

for your piping 1994 - 2002 Dodge 5.9L Cummins Twin Turbo Kit
with a good set of twins and a trans you can hit 600 hp very easy
