Powerhouse Stage 4 Turbo Kits

For the ultimate in top-end horsepower and torque, coupled with fast response, the Stage 4 System leaves no questions to chance. This is one of the most powerful single turbo systems available for the Supra TT, period. Featuring the venerable dual ball-bearing ITS GT74 turbocharger fitted with a larger Q-trim exhaust wheel, the Stage 4 System can make upwards of 800 RWHP at 32 psi on a mildly upgraded or fully built 2JZGTE engine. At this level, PHR recommends larger upgraded camshafts, a full engine upgrade, and cylinder head porting to accommodate the higher boost levels and airflow requirements of this larger turbocharger. The Stage 4 System includes the original top-quality HKS 50mm stainless steel header, HKS GT 60mm external wastegate, 65mm 321 stainless steel wastegate dump tube, 4 mandrel bent downpipe with V-band connectors and 18mm wideband bung, 4 mandrel bent midpipe with V-band connectors, 3 mandrel bent drop down intercooler piping, please specify if you have a greddy 3 row, hks type R or S, high gloss 3-ply silicone connectors in red, blue, or black, 4 air intake tube, 4 K&N high flow air filter, GT74 turbocharger with polished ITS compressor housing, 10AN stainless steel braided oil drain line, 4AN Teflon stainless steel oil feed line, 4AN Teflon stainless steel wastegate control lines, stainless steel turbocharger gaskets, stainless steel locking exhaust manifold nuts, stainless steel hose clamps, and all hardware for a worry-free install. The HKS exhaust manifold and all exhaust components are fully Extreme 2000 black heat coated for durability and heat reduction, and all intercooler piping is ceramic coated to reduce thermal conductivity. Also, since all kit components are the same, the Stage 4 System can be upgraded to the Stage 5 System by simply changing the turbocharger if desired. Our famous drop down design intercooler piping takes a direct route to the front mount intercooler to reduce turbo lag, therefore, our intercooler piping is specific to each brand. Please specify your brand/model of front mounted intercooler and color of silicone connectors when ordering. This turbo system is available for shipment anywhere in the world.
