Here’s just one of the many features that make our DPS Compound turbo kit so unique!

Upgrade your setup with the Diesel Power Source Compound Turbo Kit. Built for serious power gains and reliable performance under load. Engineered by diesel guys, for diesel guys.

08/25/2026

Bolt-in power. Zero guesswork.
The DPS HE300VG Turbo & Manifold Package for the 6.7L Cummins (2007.5–2024) is a matched system designed to work together from the start. Choose from three tiers: factory replacement, or our HE363VG (63mm) and HE366VG (66mm) upgrades. All are direct bolt-in and all retain factory exhaust brake and emissions equipment. Pair it with a DPS exhaust manifold, CFD-optimized for better flow and built to outlast the factory single-piece design.
One job. One labor cost. Problem solved correctly.

Our DPS HE470VG Turbo & Manifold Package is built for ISX15/X15 semi trucks that need more than stock can give. The 70mm compressor wheel — based on the HE400VG platform — bolts right into the factory location, supports up to 675HP, and drops EGTs while boosting mileage. Paired with a DPS exhaust manifold engineered with CFD software for better flow and long-term durability, this is a matched system built to work as one.
No spool-up compromise. No drivability issues. Just more capability where it counts.

Faster spool. Zero compromise.
Our Ball Bearing Turbonator® VGT combines two spool-up innovations in one turbo: the ball bearing CHRA (~200 RPM faster spool) and our patented ball bearing unison ring for more precise, longer-lasting vane control. Add in the Turbonator® VGT’s variable .45–1.1 A/R range, and you’re looking at 200–300 RPM better spool-up than a comparable fixed A/R turbo — with the exhaust brake capability to back you up on the way down the mountain, too.
Small A/R spool. Big A/R top-end. One turbo.

08/17/2026

If you’re tired of dealing with the factory VGT on your deleted Cummins ISX, ISX15, or X15, the DPS S400 Conversion Kit is built to simplify your setup. Choose the S475, S478, or S480 to match your build, then bolt on a complete system designed for better airflow, lower EGTs, and the reliability of a fixed-geometry turbo.
Everything you need is included, so you can spend less time chasing parts and more time on the road.

"This was the best mod I've spent money on." 🔥

That's straight from Eric Fillmore after putting a DPS Compound Turbo Kit on his '07 5.9 Cummins — running our Turbonator® VGT (S3) compounded with an S475. 👇

His goal was simple: lower EGTs on heavy tows. He got that… and a whole lot he didn't expect:

✅ ZERO turbo lag
✅ Lower EGTs under heavy load — exactly what he came for
✅ "Changed the entire attitude of my truck… it just wakes the 5.9 up"
✅ Effortlessly smooth acceleration, loaded or empty
✅ Even killed the diesel drone from his 5" turbo-back — quiet, but still big exhaust

Eric ran an S373 single before this. His words: the EGTs were borderline and the lag without a tune was rough. The DPS compound setup? "Way better. The best of both worlds." 💪

That's the compound advantage — quick spool AND huge top-end, more power, lower EGTs, and better drivability all at once. One turbo charges the other, which charges your engine, so your Cummins sees nearly 3X the air of a single.

Thanks for the honest write-up, Eric — this is exactly why guys are making the switch. 🙌

DPS Compound Turbo Kits are built to make more power, lower EGTs, and improve overall performance while towing or daily driving.

By using two turbos working together in stages, compound turbos deliver significantly more airflow, quicker spool, strong top-end performance, and 200–400°F lower EGTs.

Every DPS kit is CAD-designed for an OEM-style fit and CFD-tested to optimize airflow.

What if your diesel could make BIG power, tow like a beast, and drop your EGTs at the same time? 👀

That's exactly what DPS Compound Turbos do. 🔥

Here's how: air runs through the filter into the BIG turbo first, then the small turbo, then your engine. One turbocharger charges the other, which charges the motor — so your engine sees almost 3X more air than a single turbo. 💨

The result:
✅ More horsepower (two-stage compression)
✅ 200–400°F LOWER EGTs — a non-issue even while towing 🏔️
✅ Better fuel mileage
✅ Quick spool down low + huge top-end pull
✅ The ultimate high-performance daily driver

And every kit is CAD-designed to fit like factory parts, then CFD-tested to optimize airflow — so it bolts on with no cutting or custom fab. 👊

Available for 12V, 24V, 5.9L & 6.7L Cummins, 4BT, ISX15/X15 semis, plus Fummins & Chummins swaps. Kits from $3,924.
