At the time, the FJ20ET was popular as a tuning engine, and fierce battles took place at drag strips around the country. Big One’s DR30 was also modified for street drag racing. The engine has 0.5 mm oversize pistons, and a T04S turbo at 1.3 bar makes 450 PS. It runs in the 12-second range and is a wild machine… [continues].
The FJ20 is an ancestor of the SR20. It has polished ports, 89.5 mm pistons, a T04S turbo, 264-degree intake cams and 256-degree exhaust cams. At 1.3 bar it makes about 450 PS. Main injectors are 550 cc; the additional injectors are currently not activated.

The FJ20 transmission is also scarce and difficult to find. Big One’s solution is to install an HCR32 transmission. To fit it, the bellhousing, transmission mount, and propeller shaft… [continues].
Only minor machining is needed. Once modified, even if it later breaks, the HCR2 transmission can still be used—an advantage.
As another new approach, they plan to install an F-CON V Pro. Upgrading from the stock 8-bit system to 16-bit allows support for modern ball-bearing turbos, promising more power and sharper response. It also removes the troublesome stock flap-type airflow meter. A dedicated V Pro harness is being made.
