Builds Dirty Koala Build - Cummins Common Rail + NV4500 + HF2AV Swap

[mjosoba]

My old boss is getting ready to sell his HO CR. The wheels are turning. 500k miles, but doesn’t miss a beat, nearly 0 blow by, doesn’t use oil. Just the rest of the vehicle is failing.

Awesome! Do you have any notes on the wiring mods you did to the painless harness? And I am excited to hear there might be swap parts available soon.

What you're doing to the engine sounds very similar to what mods are on my truck currently (dual disk clutch, 90 horse injectors, mod'd cp3, head studs, and a few tunes) and that setup will be an absolute monster in an 80

I have a plan for the wiring harness, but haven’t made the modifications yet. Plan to do that soon.

The motor has been built to easily hold 700hp, but the plan is to cap it around 500hp.

Head studs w/MLS gasket, 12V forged connecting rods, 104lbs valve springs, performance cam, more fuel capacity through the CP3 and larger injectors, bigger turbo, 5 custom tunes & a Fluidampr to smooth if all out.

I'm worried for my wallet when I ask how much?

Sounds great, I'll be following along.

For the he351, check out the turbo lab of America upgrades. I'm using that turbo in my compound set (4bt) with the larger turbine wheel and it's amazing. I've read that without the larger compressor wheel on a 6bt, it produces high backpressure, but ymmv. The larger compressor wheel has been amazing for me.

Love it. Did you do the spring waste gate control or an oem style diaphragm (boost reference) waste gate control?

I run a stock, ported wastegate he351 on the 12 valve in my ZF6 Superduty. Spools quick, tows good. EGTs do run on the high side towing. Been wanting to try the larger turbine. But it works fine as is. It can get on the freeway at 85 mph or tow 30k gross up 7% at 65. And zero smoke with 5×.013's.

It came with a boost reference style waste gate. I may add a boost elbow if I feel the need to increase the boost.

Yeah these HE351’s are great turbo’s for the “mild” Cummins build. Once you go north of 600hp you need more air than these cane supply.

Yeah, but in a cruiser, you're talking driveshafts and diffs well before that point.

Keep it up man, love the build.

No idea. I’ve avoided asking him specifics so I don’t buy it. But I’m doubting it’ll be very much. He said it’s just work out, body/frame/axle wise. He drives it several hundred miles a day. I don’t drive that far. I keep telling myself I don’t need it.

Exactly why we are going to limit the top tune to about 500hp. At that point we are already in the breakage zone if not careful. One of the tunes is going to be an off-road tune to really dial back the power and response time to help avoid breakage.
