I am currently installing this package in 1990 Bronco with a 6 inch lift also installed. If anyone has any questions PLEASE ask.

Stock Turbo on JD4045
What is it? Will it be suitable for road use?
Hard to Say, that's the exciting part ;)

Here's your Borg Warner: https://www.mddistributorsstore.com/borg-warner-turbo-systems/318615/new-turbocharger

It's a large non wastegated turbo for low boost. It's gonna be lazy and slow on-road.
I'd fit a T3 flange and find a Holset HX30.

Thanks for checking into that. I am a ways away from optimizing HP
T3 is the most universal turbo flange for this size engine. If you are fabricating I would fabricate to T3 and run an adapter to T4 if you're bolting up the factory turbo.

Future proofing.
Thanks again for you help, and what you say makes sense now, after seeing the T4 to T3 adapters all over. Trying to use the stock manifold, pushes the turbo closer
to the steering shaft. the 45 angled stock manifolds are hard to find, this aint no CUMMINS, bigger chunk of iron. :)
Yeah I've seen these engines in gen-sets.
Yes, they are Industrial and Marine, never went after automotive, that I am aware of.
UPDATE, the SS 90 degree elbow I have ordered is T4 to T3 , so the HX30 turbo,s are not that easy to find, so I pulled the HX35W of the 24V Cummins I have for sale, and
will use that, together with a 30 percent increase in fuel. I should have some pics early next week.

Thanks , Steve

HX35 is too big for these engines and won't make much boost until very high rpm. The HX30 is a lot more active.

Well this subject has a lot of content on this site. Some have had GOOD luck with using it, but I realize there
are lots of variables. If nothing else, I will have a T3 mount for playing.

With the JD4045 having the oil pump at the front, makes installation much more interesting !

Interesting to see if balance shafts cancel out vibrations!

That,s what makes these engine,s so Superior. On a Genset, you can start them up,and they don,t start walking across
the floor like other engines, Super Smooth !

I should also point out that the Dynamic Balancing is a build option !

Currently working through oil pan modifications. The oil pump pickup needs to be sucking from the
deep rear sump, not tho original center. I also have to put a 6 inch access port to allow hooking up
new suction tube. A few pics,
