EXTERIOR: TOPSECRET Front Bumper spoiler.

INTERIOR: SPARCO Racing seat, BLITZ Boost Controler,
HKS Meter box with TRUST Oil Pres., Oil Temp.,
Boost Gages. Audio system with CD Changer

ENGINE: Ordered made STAINLESS MUFFLER, HKS
Airfilter, TRUST Intercooler, TRUST Oilcooler,
TRUST Racing piping kit, CUSCO Towerbar,
OS GIKEN Twin plate racing crutch

This car modified as a boost up and horse power is
420hp and 80kg torques at 1.2kg boost.

Note 420hp = 357RWHP ... which is a below-average number for a bpu++ Mkiv Supra. I wonder why they've never run it over 1.2kg/cm2 (17 psi)?
