hey i have the stock hx35 in my 1996 dodge diesel and was just reading my diesel power magazine and saw they have more aggressive aftermarket compressor wheels for the hx35 turbo for around 220 has anyone ever bought one or know anything about different wheels they showed a chart on a dyno that the more aggressive compressor wheel increased the boost from 32psi to 42psi and had lower egts and quicker spool up any one ever bought one or know anything

 

the most common upgrade for the hx35 is a hx40 compressor wheel swap making you a 60mm compressor. the 6 blade hx40 compressor is the most aggressive. i have also recently found that s200 wheels fit the shaft of an hx35 and 40. they have very similar profiles to s300 wheels and im sure flow more than the hx35 but i have no proof to back this up. anyways a hybrid hx35/40 is a decent upgrade if you are on a tight budget. you will still be very held back on the turbine flow but you will see a gain. for the money you will have in your hx35 $220 and labor to install and balance the assembly, i would prefer an he351cw swap. its a better turbo similar to yours but slightly bigger with a smaller housing and it would cost you the same money to just swap chargers. and now with a larger turbine you can squeeze a few more ponies out of the old truck.

stock hx35 is a 56/58/12 im pretty sure
stock he351cw is 60/60/9
a hx35/40 hybrid can be made 2 ways a 60/58/12 or a 60/65/12 the later being more expensive because you machine the housing to fit the 40's shaft.
the shafts and bearings are the same size in the hx models the only difference is the compressor size and the turbine size. the 351 has slightly different bearings.

 

Each wheel when manufactured is balanced ...... just so ya know ...... u can rebuild it either way and don't need anymachine shop help unless like stated ... u need to stuff big wheel in small compressor housing .... the hx35 is a good to start from platform ..... the hx34/40 is ok ...... he351's have there limitations as well ....... if u have some money to spend a s300-(62/65/14) will support around 400-425 easily ..... more has been made .. with this set up ...
For pulling and heavy towing the hx with a ht3b as secondary is phenominal from all that I hear ..... this is what I'm planning on running after I finish studs and oringing head and such ..... should be around 450-500 .... safely

 

i dont want to go threw the trouble and money for studs or id put a 62mm or 64mm

 

you can run a 62mm all day long @ 40lbs and newer see a problem. any bigger and i would start to fret. i would not worry about that size charger.

 

WHAT .... I'm runnign the stock HX35W and I overboosted mine and poped my HG ......

SERIOUSLY .... if you want to make anything more than stock power levels ..... STUD IT UP ...... or you will have to do a HG real soon ..... I can take a pic of my engine and send you pics, hell I will send you a video of it leaking while runing just to prove it .....

Its a fatal issue the 6BT has ..... studs are around 500 bucks .... way cheeper than a new turbo .... and its a real good insurance policy ... then you can play and make all kinds of power ...... well ... up to about 500 .... then you will have to do stus and O-rings ... then you cna play a little more ... thewn it gets serious after about 550hp

I will be doing a full build pics and all on mine this winter .... have to finish my Ol' IDI for winter ... will be posting all theose pics as soon as its running ..

 

its not because of the boost pressure its because of the drive pressure. people dont get that. do you know what your drive pressure was before you lost the gasket? i bet if you were over 50lbs on the hx you were over 100PSI on the exhaust side. THAT is why you blew a head gasket. things werent anywhere near 1 to 1 and way out of harmony.

studs are good insurance but not nearly as necessary as the internet makes them out to be. a good flat block and head and a good even torque job get you a long long way.

 

Go with a new turbo, I like the S300 series for power, reliablity and economy, if you have the $. You can sell the old one and then add a second if you like later. Please get the head o-ringed or fire-ringed and studs and good gasket (and have it assembled right, as the previous gentleman so nicely suggested) before you play with it too much or you will learn about the rebuilding process sooner than you might like. Good luck. I am looking at upgrading my stock turbo as it is working great and running well but the cost and investment may outweigh the benefits when you look at what is out there to do a bolt on upgrade. Just say in.

 

Thanks Cheesy,

If you wanna play llike the big guys , its not cheep my friend, but if you dont heed the warnigns it will cost you far more and when u dont have it either..... I would know ..
