The Toyota 86 (FR-S or BRZ) does everything quite well, right up until the moment you mash the throttle. The chassis would make an amazing race car, but something has to be done about its OE powerplant. Enter Rocco Bocchicchio of Level Motorsports who owns the S50 powered E30 BMW Time Attack car we’ve been long time admirers of. Rocco is the real deal. He can fabricate with the best in the industry and his attention to detail is a big part of his success. So when Rocco approached us about teaming up on his latest creation, we could not pass up the chance of being able to document the process. Rocco wanted to build a new chassis to compete in as the E30 was far from being a contemporary piece. He wanted something with modern suspension and with more sponsorship potential, a Toyota 86 for the Rear Wheel Drive Unlimited Time Attack Class.
Rocco is taking an unusual turn in building the car, instead of the usually forced induction FA engine or even a 2JZ swap, Rocco is instead using the BMW S50 engine from his E30 to power the 86! The main reason is that the S50 has a lot of power potential, is bulletproof and has been developed by Rocco to be a proven part of the equation. Let us look at Rocco’s first steps in building the 86 from scratch and using some stuff by obp Motorsport and Fuelsafe.
Our donor car was one that was bought cheap out of state as a flood-damaged car. Since it was only going to be used for the shell and parts, this was not an issue. Rocco first built a dolly to hold the car while it was being built.
Building a race car with true race parts is really the way to go. Instead of having the factory hydraulic system with its ABS and electronic proportioning, all of which would not be working in this car since it would not have the factory ECU and wire harness, a true racing brake system with a pedal box and a bias bar is by far the best option.
An obp Motorsport Pro-Race V2 floor mounted pedal system was selected. This is a great part for the price. The pedal box sits in a stiff mild steel cradle chassis with aircraft grade aluminum pedals. The pedals activate Alcon master cylinders and have an adjustable pedal ratio from 4.9:1 to 5.24:1. The pedal pads are adjustable in up and down directions as well as side to side.
