Tomei ARMS 7760 Bolt On Turbo 400 WHP (WRX/STI)- $1659.00 Shipped
The ARMS M7760 is the largest bolt-on turbo possible that TOMEI engineers can fit into the limited space of the EJ engine. Despite the size, the internals of the turbocharger speaks otherwise; extracting the most and finest efficiency from its design. With bolt on exhaust system, we have seen the dyno horsepower up to 390 to the wheels.
This is a 100% bolt on kit for USDM Spec EJ20 or EJ25 engine, including gasket and coolant lines.
Tomei Oil Pan Baffle Stiffner - $399.00 Shipped
At TOMEI our testing found that there is insufficient oil supply in the crankcase from the oil pan. Our Baffle Stiffener adds strength where needed by bridging both left and right of the crankcase by utilizing dual structure to improve rigidy. Also oil cavitations are prevented with the use of rubber baffles to improve a stable oil supply. Tomei confirmed that this solved the problems in extensive testing. Another must have upgrade for EJ20 owners for circuit use.
