I like your stub shaft. Most people use non-telescopic shafts and I'm a believer that no matter how well you align the trans/TC, as things shift, the bearings in the two inputs/outputs are going to suffer.

I'm dropping the 4BT/NV4500 in the J300 this weekend

Stainless Hydraulic Line

Where did you get that stainless hydraulic line made? Nice.

What rearend ratios are installed in your Dana60 axles?
With your 35X12.5R15 tires, how many RPM are you turning at 70MPH?

Mikel. I too am a believer that NOTHING in the driveline will stay stationary, inline, whatever under load.......especially 425 ft lbs of torque at 1500 rpm. Bearing would suffer greatly. Hope the transplant goes well for you this weekend.

As for the stainless hydraulic line. I found a shop that will take a fitting and put in in another fitting and marry it in a braided line. They do straight and ninety degree fittings. Never seen one on a rig so I thought Id give it a try.

Axle ratios are 4.10. At 70 MPH and .76 OD, that puts my rpms at about 2050. I have some 36s to go on soon. I think that knoks down to 2010 to 1950 er rpm calculator.

they love 1700-1900 rpm window over 2k they suck fuel much more. like 4-6 mpg difference. gear appropriately. 4.10s with 35's should be a good combo. check the size of your turbo exhasut housing they pickup a little bit when you swap on a hy35/ 9cm. i had one running a hx35/12 with a WG and when we swapped on the hy35/9cm it was quit snappier especially with a little extra fuel added.

good luck

Door panels

Dusty, turbo is a HX30. In stock trim my CPL made 350 TQ at 1300 RPM. Fuel was turned up slightly and added and ATA cooler.

Got the rough fit done. Now I just need to slap some insulation on the backside. Ill probably shoot some hammered gray metalic too.

hx30/ ? i think they used a 14cm exhaust housing but cant remember, anyways put a pyro on that baby and a boost gauge and keep your eyes peeled on the diesel pages the hy35 w/ 9cm exhaust housing is too small for the bigger 5.9s when you turn then up but pushes more air under load than a hx30 and with the smaller exhaust housing will spool a little faster. all food for thought. dont be bashful turning those things up they handle it really well.

Looking good

I agree. But, don't let mcinfantry see that, he will tell you it won't work and if it does the engine won't last.

little over 400k miles on one that i did for a friend ina chevy in montana right at 500 ft/lbs at rear wheels and over 230 hp. tows all the time pushes 35 +/- psi. have several others less smokey no issues. egts climb quickly but he has a pyro and backs out at 1300*

one of these days im going to get around to building one with a set of twins on it so i can keep egts down. and have a little more fun. i built a set of twins for my 5.9L 12v and had a blast for 200k miles on a engine that now has 350k and is still going. These engine take alot they are way over built and detuned.

Im thinking a hy35/9 (450 cfm) 54mm/9 top but im having trouble getting the right map for a bottom turbo fround a S300 66mm/16 that is mapped at (800 cfm) i need something with a map closer to 900 to get a proper drive pressure ratio. collecting parts right now

Well after seeing this I'm scrapping my truck mid project and starting over!!!


Yeah right

Very nice work, I probably should have went for a 4 BT.. Guess I'll just have to get a 4 BT for the 53 Chevy Panel van buildup. I may hit 425 TQ in my stroker SBC but I don't think I'll see it at sub 2000 RPM. The hydroboost setup is also quite slick. I just got my GM Master Cylinder and pedal installed for my nv45's hydraulic clutch.

Really nice work, I'm quite envious of the results on your truck.

Dusty- I dont think Ill be going to a larger turbo. I have GREAT response and power as is. Ill have to put a pic up of the guages. I have a pyro, oil pressure, tach, water temp, and boost mounted on the pillar. I plan on monitoring everything.

Friday is finish the door panels. Hopefully wire up the back up lights. Well generally finish the interior. Im sure there will be bugs that creep out for the next few weeks but thats expected.

yeah some know when to stop, some get bitten by the bug and hp is addicting. the hy isnt too much bigger its the exhaust housing that makes things a little snappier. i just like to throw it out there. as it was for me i started out stock and of the opinion that that would be plenty. then as i started adding i found my mileage didnt change much or actually went up a hair then in some sick way i justified it all. i think i was in it 200 for injectors, 250 for the turbo and then did some pump timing and adjustments as well as a set of gov springs

so long as i didnt mash the throttle to the floor the duty cycle didnt change at low boost it was only progressive, so lumbering down the road consumed no more than it did in stock or slightly modified form as i increased throttle it increased hp and then rear tires started rotating more easily and passing cars on the hills became very entertaining whithout down shifting......

Anyways i like to always try and influence people more towards the dark... smokey side of things. either way that truck is sick and if you ever do decide you love the power and want to add a little more neck snap remember these few tricks they are cheap and easy upgrades.

HY35/9 from a 99-2002 automatic dodge 24v (auto only)
POD - Lucas injectors
Pump timing loosen pump nut crank towards block. or have some one turn her up timing helps no mater what.
gov springs for a 89-93 12 dodge any performance shop Cheap $30-150

I love the gauge s on the pictures, that is a super clean install im keeping your pictures just to keep my motivation up to convert my chief someday.

Dusty, youll love this. I have the coveted P 7100! Not many 4Bs running around with those.I had a set of 3000 GS installed. Never know when you are towing something and you need the extra room to go.

those are coveted and good job on the gov spring install. shoot if you have the p7100, did you take the torque plate out and re-grind it? when you tuned up other things ? or which plate did you install, or did oyu slide stocker forward.

SWEET smoke

yep. like i say PROVE ME WRONG.

untill someone runs 60,000 miles on 400hp 4bt, i dont care what you THINK will work.

he said 350tq, NOT 350hp.

Mcinfantry,
Yes 350 tq, that is the key. I enjoy the motor as is. It passes uphill at highway speeds, gets mid 20s mpg. The only mods are turning the fuel up to match the air charge, nothing radical.

I know you have been saying build a 400 or whatever HP 4b and show me how long it lasts. I think I may have a way to demonstrate that without building one......tell me what you think.

If you plot on a linear regression the life expectancy of a motor vs peak horsepower it produces, you will get a curve. Start with a stock motor to top fuel and you will get a curve that runs from 200,000 miles to 1/4 mile. The more you power you demand the engine to return, the shorter the life. Large amoutns of power drastically decrease motor life.

Why are you not going to run the Hydro units? I got my squared away and am happy thus far.

i couldnt come up with an agreeable means to run any stick, so ive reverted to auto.

i understand what you srae saying on the curve. i think its just not possible to get that much reliably.

but, heres a thought.

cpl 2498
175 bhp @ 2500
420 ft-lb @ 1600
bosch "a" inline pump with rsv governor.

best part????????? ist a 4bna

Yeah..... reliabilty does go down......and quick.

Good luck with the auto. Are you thinking the 700r4? I think it would be a great option. With appropriate torque converter and maybe shifter servos, it will be a great trans.

Hope it goes well and keep us posted.
