"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.

Understand the differences between our VGT turbo and the S400 Complete conversion kit before you make your next purchase!

08/12/2026

Why pay $7,000–$10,000 to replace the turbo in your Cummins ISX, ISX15 and X15… when you can UPGRADE for less? 🤔

The factory Holset VGT is good — until it isn't. When it fails again, end the cycle. This is the DPS S400 Turbo Conversion Kit for the Cummins ISX, ISX15 & X15. 🔥

The S400 is a fixed-vane turbo — NO actuator, NO moving vanes, and far fewer failure points than your stock VGT. 👊

✅ 3 sizes to match your truck: 75mm / 78mm / 80mm (550–750 HP)
✅ Complete kit — piping conversion + the highest-flowing DPS T6 exhaust manifold on the market
✅ Pre-tapped exhaust pressure sensor port
✅ Every part CFD-tested for high flow
✅ Lower EGTs + better fuel mileage
✅ 1-Year / 100,000-Mile warranty

On a previously deleted truck it's a complete direct bolt-on — bolts to your intercooler, your intake, the manifold bolts to the engine, and the turbo bolts right to your exhaust. It's a one-stop shop. 💨

Fits Cummins ISX / ISX15 / X15 (2008–2024) — Freightliner, Peterbilt, Kenworth, Volvo, International & Western Star. For previously deleted trucks only.

Want the best of both worlds on your 5.9 or 6.7 Cummins? DPS compound turbo kits pair an S300 high pressure turbo with an S400 atmospheric turbo for instant spool and serious top end airflow. Everything comes in one box: both turbos, manifold, piping, oil lines, and hardware.
Expect 200 to 400 degree lower EGTs and 400 to 1,200+ HP capability depending on your setup, plus a true bolt on install with no cutting or fabrication required.
Better spool, better airflow, better towing and performance across the board.

Upgrade your Cummins ISX15 or X15 with a DPS Compound Turbo Kit built for faster spool-up, lower operating temperatures, and improved throttle response. Choose from S472/S488 or S475/S488 configurations to match your horsepower goals.

By combining two S400 turbos in a compound setup, you get quick low-RPM response with the airflow needed for heavy hauling and high-horsepower applications. Complete with a DPS high-flow exhaust manifold, this kit delivers the best of both worlds without the compromises of a large single turbo.

Your stock VGT turbo isn’t going to last forever. When it fails, don’t replace it with another turbo that has the same known weak points. Upgrade to a 3rd Gen Swap Kit for improved reliability, lower EGTs, more horsepower, and better performance all around.
