Jarret Humphrey's the founder of PHR and I go back to the 1990's and were part of the group of American Supra enthusiasts who put the potential of the 2JZ on the map. We now offer the entire Powerhouse Racing line here at SupraStore.com.

If you are looking for the ultimate quality Single Turbo System for your Supra look no further. PHR reliability speaks for itself in the world of high-end performance, and when coupled with the powerful lineup of PHR turbochargers, the result is unmatched.

The PHR Stage 1 Single Turbo System is designed to fill varying needs, and can function with the factory fuel system and electronics to reduce cost, or can be coupled with the PHR Stage 1 fuel system and MAP ECU for the ultimate in power and response. The PHR Stage 1 is capable of 520 RWHP at 18 psi utilizing the factory fuel system and electronics, or 630+ RWHP at 29 psi using the PHR Stage 2 Fuel System upgrade and MAP ECU. This turbo system offers full boost (18 psi) by 3800 RPM and a broad, flat torque curve up to RPM redline. Because of the quick-spooling characteristics and broad torque curve of the Stage 1 System, this system is best suited to street cars and road-race cars.

The Stage 1 System includes the new PHR stainless steel header, Tial or Precision external wastegate, 65mm 321 stainless steel wastegate dump tube, 3" hand-built mandrel bent downpipe with V-band connectors, 3" hand-built mandrel bent midpipe with V-band connectors, exclusive PHR-style "drop-down" 2.5" mandrel bent aluminum intercooler piping, high gloss 3-ply silicone connectors in red, blue, or black, 4" air intake tube, 4" K&N high flow air filter, GT60 series turbocharger with fully-polished PHR 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. As an added bonus, the downpipe includes an oxygen sensor flange for the Toyota unit, as well as an 18mm bung for a wideband sensor.

The HKS exhaust manifold and all exhaust components are fully Extreme 2000 black heat coated for durability and heat reduction. Since all PHR Stage 1-5 Turbo Systems are "modular" in design, all can be upgraded with minimal changes so no components have to be wasted. Our famous PHR-style "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. We can also supply fully polished oil lines and fittings for a show appearance at additional cost. This turbo system is available for shipment anywhere in the world. Accept ONLY the best for your Supra Twin Turbo.

Note: Please choose your desired color of silicone and specific Intercooler pipe to fit. The new PHR manifold design is included with this kit (see pic of raw manifold). This is an amazing design and replaces the picture of the black version. You will receive a 2000 degree F coated manifold (not raw). All PHR turbo kits are built to order, so please allow 4 weeks for completion.
