Built for Nissan SR20DET owners who want a serious jump in flow without reinventing their turbo system, this Garrett GT2871R with a GT28R style compressor housing and high pressure adjustable actuator delivers a true bolt-on upgrade path. It retains the familiar T25 style footprint many SR20 kits are built around while unlocking significantly more airflow than a stock-style GT28R. This is the turbo for enthusiasts who want stealthy packaging with real performance underneath.

Performance & Application
This GT2871R configuration is designed for small displacement engines up to 2.2L, making it a strong match for the SR20DET platform. The dual ball bearing center section gives it the ultimate spool up time compared to other units, while the larger 71mm/52 trim compressor wheel and GT28R style housing push flow capacity well beyond typical GT28R output. The external packaging can be made to look identical to a stock GT28R when the GT28R style actuator is selected, allowing for a stealthy upgrade that steps up total flow potential without requiring a major re-arrangement of existing plumbing or mounting points. It’s an ideal choice for builders who want more headroom while keeping quick throttle response.
