If you're looking to crank up the power on your build, the Garrett G42-1450 turbo assembly kit is worth a serious look. This bad boy is engineered to handle some serious horsepower, boasting a capacity of up to 1450HP. Whether you’re working with a compact 2.0-liter engine or pushing the limits with an 8.0-liter beast, this turbo has got you covered.
One of the standout features is its quick spooling capability. You’ll notice that low inertia compressor wheel working its magic, giving you faster boost response when you hit the gas. That’s a game changer when you’re trying to get the most out of your ride. The ten-blade, forged G Series compressor wheel isn’t just about looks—it’s fully machined for high-flowing aero, making sure you get that sweet power delivery without any hiccups.
Speaking of efficiency, the new turbine aero wheel is a notable upgrade. It flows 10% more than the previous GTX42 model, hitting a peak efficiency of 77%. For those of you keeping score, that’s a step up from the GTX42’s 74% with a 1.01 A/R. This means you’re not just getting power; you’re getting it more effectively.
Durability is also a big deal with this turbo. It’s built with inconel super alloy, so it can handle operating temperatures soaring up to 950°C without breaking a sweat. You can push this turbo hard, and it’ll keep coming back for more.
Now, let’s talk specs. The compressor wheel has an inducer size of 79mm and an exducer size of 98mm, with a trim of 65. On the turbine side, you’re looking at an inducer of 82mm and an exducer of 75mm, with a trim of 84. The compressor housing A/R is set at 0.85, which complements the overall design perfectly.
When it comes to installation, you won’t be left hanging. The kit includes a variety of coolant and oil fittings, flanges, and components to make your life easier. You’ll need two 14mm coolant fittings and lines, and for oil, there’s a -4 AN feed flange with a built-in restrictor, plus gaskets and drain options to fit your setup. The V-band inlet and outlet flanges and clamps are also included, ensuring a tight and secure fit.
In short, the G42-1450 isn’t just another turbo; it’s a solid investment for anyone serious about performance. With its blend of quick response, high efficiency, and robust construction, you can trust it’ll deliver the power you’re after. Just make sure to check out the alternate coolant and oil fittings available if you need something specific. This turbo is ready to take your ride to the next level!
