VVTi 1JZ Bolt-On Turbocharger Upgrades
Our location in Vancouver, Canada puts us at an advantage when it comes to developing a turbocharger for Toyota's VVT-I 1JZ engine found in JZX100 and JZX110 sedans. As these cars have been legal in Canada for over 15, we have accumulated an excessive amount of hands-on experience with these unique motors.
If you've been able to drive or even be a passenger in a VVT-i 1jz vehicle, you will understand how well the low and midrange power has been improved over the previous 1st generation 1jz. With the stock engine package however, this has come with a comparative reduction in top end power output.
Our aim at the beginning of the development of these turbochargers is simple: Develop upgrade turbocharger options that are well matched to the low and mid-range Volumetric efficiency of these engines. As with all our products, we aim to maximize value, while also allowing for full customization of your Turbocharger system for Motorsports usage.
SM505/R- Perfect Power Characteristics.
Our latest update of the SM500/R kit is built around our latest dual Ball Bearing CHRA, with a 55mm Turbine and all-new Billet Compressor Wheel Capable of supporting up to 55lb/min of airflow. Improved rotor group sealing, with the addition of twin seal ring assemblies, ensure reliable sealing at both ends. An upgraded internal wastegate actuator is included, and can be calibrated for boost pressures between 14 and 20 PSI. Usage with or without upgraded camshafts can still provide impressive results. Output up to 500BHP can be expected with supporting modifications, however we have found this power range is difficult to surpass with the OEM Exhaust Manifold.
**Available with Either stock-fitment Compressor Housing or 3" intake w/ filter option**
SM555/R - Additional features and performance
Our Highest-Power VVTi 1JZ bolt-on Turbocharger kit is built around our 57/LPR Compressor. This Compressor features a high-trim, low-Inertia 57mm Compressor Wheel with a high degree of blade backsweep. The result is up to 60lb/min of airflow, with increased efficiency at low-mid range Pressure Ratio and very good surge resistance. This turbo features an all-new CHRA and can be built around an either Iron or Aluminum Bearing Housing, reducing mass and allowing for the unit to be fully corrosion resistant, Twin seal rings on both sides of the rotor group increase sealing effectiveness. This option is now offered with a higher flowing, investment-cast stainless Artec .85 A/R turbine housing for increased power potential and lower EMAP.
***Please note - the standard option for these Turbochargers has the OEM bolted flanges for both inlet and outlet of the Compressor housing and can work with either the OEM J-pipe or aftermarket J-pipe delete. While this is a lower cost option, we heavily suggest using our 3" inlet version.
The factory J pipe is known to be quite restrictive, and most of the aftermarket J-pipe deletes available are less than ideal, with a sharp reduction in diameter.
Our intake option includes a 3" aluminum intake, with provisions and lines for both the IACV and the valve cover crankcase breather. This kit also includes a K&N Filter, along with couplers, clamps, and a hot pipe piece to connect to your OEM charge pipes or any upgrade intercooler / piping kit. This compressor housing also increases efficiency and power capability.
For those running a JZX110 engine, or anyone else who will not require the factory IACV plumbing, please email to have the secondary port omitted.
