If you're looking to take your turbo setup to the next level, the Garrett G30-660 standard turbo assembly kit is worth a serious look. This isn't just another turbo; it's built with some serious tech that really makes a difference on the road or the track. With a 3" inlet and a 2" outlet, this turbo is ready to deliver when you need it.
One of the standout features here is the new G Series compressor wheel aerodynamics. It's designed to improve efficiency while still packing a punch. The fully machined speed sensor and pressure ports mean you can keep an eye on performance without any guesswork. Plus, it comes with both standard and reverse rotation options, so you can tailor it to your setup.
Worried about durability? The one-piece center housing and backplate are solid, and the Mar-M turbine wheel material can handle some serious heat—rated up to a staggering 1050°C (1922°F). The stainless steel turbine housings also match that heat tolerance, so you know you're not going to run into issues when you're pushing your engine hard.
Installation is straightforward, too. The kit comes with an oil restrictor and water fittings, plus four water jacket ports for customizable installation. You’ll also get all the necessary hardware, including V-Band clamps for both the inlet and outlet. Just make sure you grab the right flanges: the inlet V-Band flange is ATP-FLS-350, and for the down-pipe, it's ATP-FLS-351. Don't forget the oil drain flange and gasket—those are crucial for a tight fit.
In terms of specs, you're looking at a compressor wheel inducer of 54mm and an exducer of 67mm, with a trim of 65. The turbine side has a 60mm inducer and a 55mm exducer with a trim of 84. The compressor housing has an A/R of 0.70, which helps with spool time and overall performance.
This turbo is a fantastic choice for those who want to push their build without compromising on quality or reliability. Whether you’re hitting the streets or the track, the G30-660 is ready to deliver the boost you need.
