The 5.9 Cummins turbo is the main reason your truck’s engine is significantly more powerful than a similar-sized engine from decades ago. The turbo compresses air and forces it into the engine. More air allows more fuel to be burned, which ultimately means more power is produced. However, turbochargers have a finite lifespan; eventually, you must replace this essential engine component. +Read more
When replacing a turbocharger, you can opt for a stock turbo for 5.9 Cummins. This is a like-for-like replacement, and the new, official part will perform exactly like the old one when it was in optimal condition. If you’re happy with your truck’s performance, this is likely the best option.
However, if you want to get a bit more out of your vehicle, you can perform a 5.9 Cummins turbo upgrade by overlooking the stock turbo and opting for an aftermarket turbocharger instead. If your old turbo needs replacing, it’s an ideal time to perform a Cummins turbo upgrade 5.9, as the labor involved is pretty much exactly the same. The only difference is some minor tuning to adjust for the new Cummins 5.9 turbo’s increased performance.
If you were to opt for a 5.9 24V Cummins turbo upgrade later, it may be significantly more expensive. Not only would you have splashed out on a stock turbocharger, which will, at best, be sold on as “used,” but you would have to either pay for the labor involved again or take time out of your own schedule to install it yourself. So, if an upgrade is on your mind, then the end of your previous turbo’s service life is a golden opportunity to perform a turbo upgrade for 5.9 Cummins. Yes, the part may be a little more expensive, but you’re saving a lot of money overall.
