If you're looking to push the limits of your build, the Garrett GT4508R turbocharger is a beast you need to consider. With a hefty 108mm compressor wheel and a turbine wheel measuring 87mm, this unit is designed to handle some serious power—up to around 1200 HP, to be exact. That’s enough to get your heart racing and your tires squealing.
What sets this turbo apart is its compact 42 footprint and the divided T4 turbine housing with a 1.15 A/R ratio. This design not only helps with quicker spool times but also keeps the exhaust flow efficient, so you can make the most of every rev. It’s a solid choice for those who want to make their engine roar without sacrificing responsiveness.
When it comes to installation, you’ll need a few extra parts to get everything running smoothly. Here’s what you should grab:
You'll also need a T4 turbine inlet flange, which you can find under Product Code: ATP-FLS-057 if you prefer mild steel. Don’t forget the gasket for the divided T4 turbine inlet (Product Code: ATP-GSK-014) to keep everything sealed tight.
Just a heads up: there are alternative coolant and oil fittings available if you want to customize your setup. This turbo is a serious upgrade for anyone looking to make a real impact on their ride's performance. Get ready to turn some heads—and maybe break a few speed limits.
