ISR Performance - RSX3576 Turbo - T3 Inlet / V-Band Outlet - 0.64 A/R
Preorder date - Nov 2nd 2026
Available on backorder. Ships from ISR Performance in 2-4 weeks
Sized for 400 to 500 wheel horsepower on 2.0 to 2.5 liter engines, the ISR Performance RSX3576 turbo in the 0.64 A/R configuration is the quicker spooling of the two RSX3576 housing options. The T3 inlet flange and V-band outlet make it a straightforward match for SR20DET, KA24DE-T and RB25DET builds running an ISR T3 top mount or bottom mount manifold.
A tighter turbine housing builds boost sooner and delivers strong mid range, which is exactly what a street car or drift car wants when it needs to be on boost coming out of a corner. You give up a bit of peak flow compared to the 0.82 A/R version, but for most 2.0 to 2.5 liter engines in this power range the trade is worth it.
Suited to 2.0 to 2.5 liter engines such as the SR20DET, KA24DE-T and RB25DET. Requires a T3 flange manifold, such as the ISR top mount or bottom mount manifolds, plus a V-band downpipe and supporting fuel and tuning.
All ISR Performance products are designed for off-road use only.
